150TQJ(R) Electric Borehole Pump
You've got a borehole to run, whether that's a farm needing steady irrigation water, a municipal wellfield, or a factory that can't afford downtime — and you need a pump that goes down the hole, stays down there for years, and just works. The Hydroman 150TQJ(R)5-150 is a multistage submersible borehole pump built for exactly that: continuous groundwater abstraction from deep wells, with the flow and head you'd expect from a 150 mm diameter, 3 phase borehole pump designed for real working boreholes rather than a catalogue spec sheet.
It sits at the practical middle of the borehole pumps for sale on the market today — bigger and higher-head than the domestic 4-inch bore pump submersible units, but sized to fit standard 150 mm+ casings so it drops into most irrigation, municipal, and industrial boreholes without a special-order well. If you're comparing submersible borehole water pumps and trying to land on the right model rather than the biggest number on the page, this is the page to read before you request a quote.
What You Get With the 150TQJ(R)5-150
You're buying a pump and motor pairing, not just an impeller stack. Every unit ships as a complete submersible bore pump and motor assembly — multistage centrifugal pump end, matched submersible motor, and the mechanical tolerances needed to run fully submerged for years at a time.
A few things define how this pump behaves in the field:
The multistage centrifugal design stacks several impeller and diffuser sets on one shaft, so each stage adds a bit more pressure until you reach the head your well actually needs — this is how a compact 150 mm body produces heads that a single-stage pump of the same diameter simply can't reach.
It's built to run continuously, not cycle on and off all day, which matters if you're feeding an irrigation main or a town supply that can't tolerate pressure drops.
Materials and clearances are selected with corrosion and abrasive wear in mind, because groundwater is rarely as clean as tap water.
It's engineered around standard 150 mm+ borehole casings, so sizing the well doesn't become its own project.
You'll see this pump described elsewhere as a deep well borehole pump, an electric borehole pump, or simply a centrifugal borehole pump — they're all pointing at the same working principle: a sealed electric motor and a stack of centrifugal stages, run submerged, lifting water from depth to the surface.

150TQJ(R)5-150 Specifications
Because "-150" model families like this one are built as a staged range — the same 150 mm hydraulic platform sold in different stage counts to hit different duty points — the table below gives you the working envelope for this pump class. Your exact duty point (the flow and head pair your well actually needs) is confirmed against your borehole's yield test before we quote a specific stage count and motor rating; that's standard practice for any multistage borehole pump, not just ours.

If a "5 HP submersible borehole pump" or a smaller-diameter unit is closer to what your well can actually deliver, say so when you request a quote — Hydroman's range runs well below the 150 mm class too, and matching the pump to the well is the whole point of this exercise, not upselling you into more motor than the borehole can feed.
The short version: the pump and motor are one sealed unit, lowered entirely below the water, and the water itself is what keeps the motor cool as it runs.
Pump and motor together. Unlike a surface pump that sucks water up through a pipe, a submersible borehole pump pushes water up from below. The electric motor sits directly beneath the pump end, coupled on a shared shaft, and the whole assembly hangs on the rising main inside the borehole, fully submerged.
Multistage lift. A single centrifugal impeller can only build so much pressure. Stack five, ten, or twenty of them in series — each one's discharge feeding the next stage's intake — and the pressure compounds stage by stage until the pump produces enough head to lift water from real borehole depths, not just a few metres. This is the entire logic behind a multiple stage borehole pump, and it's why stage count, not motor size alone, is what determines how deep and how high the pump can work.
Delivery to the surface. From there it's straightforward: water travels up the rising main, through the wellhead, and out to a storage tank, pressure system, or straight into an irrigation main or municipal distribution network.
A pump can only perform as well as the borehole lets it. Three things are worth checking before the pump ever goes down the hole.
Borehole cleanliness. Drilling debris, loose sediment, and fine sand left in a newly drilled or poorly developed borehole will wear the pump's stages and can jam the intake screen outright. Boreholes should be properly developed and, ideally, pumped clear at a higher-than-normal rate until discharge runs clean before the permanent pump goes in — a step covered directly in the NRCS/USDA water well construction standard, which calls for pumping a new well at roughly 120% of its intended production rate until the water runs clear.
Air and water level. Low submergence, air entrainment, or a vortex forming at the intake all starve the pump of the smooth flow it needs, and a submersible motor that briefly runs dry loses both cooling and lubrication in the same instant — which is why the minimum submergence figure in the spec table above isn't a formality.
Borehole yield. This is the one people skip, and it's the one that matters most. Pump capacity should match the sustainable yield of the borehole — not the largest flow rate the pump can physically produce. Pulling water faster than the aquifer can replace it just draws the water level down past the pump intake, which is the single most common cause of "the pump keeps tripping out" service calls. Determining that yield through a proper pumping test, and never rating a pump above the confirmed sustainable rate, is standard well-industry practice recommended by groundwater professionals — the U.S.-based National Ground Water Association, for instance, publishes well construction and pump-sizing standards built around exactly this principle, and its member guidance sets a minimum sustainable yield of around 1 gallon per minute for continuous use, with typical household peak demand running closer to 3–5 GPM for a standard four-person household.
Which Submersible Borehole Pump Should You Choose?
Sizing a borehole pump correctly comes down to four numbers, in this order.
Pump diameter first. The pump has to physically fit the casing with enough clearance for cooling flow to pass the motor — this is the actual reason "150 mm borehole pump" and "borehole pump diameter" matter as search terms, not just as spec-sheet trivia. A pump too close to the casing wall starves its own motor of cooling water even in a high-yield well.
Required flow rate second. Don't size for the biggest number available — size for what you'll actually draw. A domestic supply, a drip-irrigation block, and a factory process line all draw water completely differently across the day, and the duty point should reflect that pattern, not a worst-case guess.
Pump head third. Total head isn't just "how deep is the water." It's the static or dynamic water level, plus the vertical lift to the discharge point, plus friction losses along the length and diameter of your rising main, plus whatever discharge pressure your irrigation system or distribution network actually needs at the far end. Skip the friction losses and the pump will underperform on site even though it tested fine on the manufacturer's curve.
Installation depth last — and this one has a common misconception. Deeper isn't automatically better. Installation depth is set by the static water level, the drawdown at your intended pumping rate, the total borehole depth, and the minimum submergence the motor needs to stay cool — not by "how far down is the bottom of the well." Installing a pump unnecessarily deep just adds pipe cost and makes future service pulls longer and more expensive.
Built-In Features and Optional Accessories
A pump on its own doesn't make a working system. Depending on the application, the 150TQJ(R)5-150 is specified with:
Where the 150TQJ(R)5-150 Is Used
Irrigation. Farms, greenhouses, and orchards running drip or pivot systems need consistent pressure through long pumping hours — this is one of the largest markets for irrigation borehole pumps generally, and one of the most sensitive to a pump that's undersized for its actual flow demand.
Deep well water supply. Where the water table sits well below what a jet pump or shallow-well pump could reach, a submersible unit is the only realistic option — this is the core use case for deep well borehole pumps as a category.
Municipal water supply. Groundwater abstraction for town and district networks, where reliability and continuous duty matter more than peak output.
Industrial water supply. Process water, cooling water, and general plant supply, often running around the clock rather than in short bursts.
Groundwater extraction more broadly. Anywhere a borehole or deep well needs to be drawn down steadily over long operating hours rather than switched on for a few minutes at a time.
Why Hydroman
Built for continuous submerged duty. The pump and motor are engineered as one assembly for years of uninterrupted underwater operation, not adapted from a surface-pump design.
Multistage efficiency where it counts. For applications needing genuine head — not just flow — a properly staged multistage submersible pump beats a single-stage unit on both output and running efficiency at depth.
A range that actually matches the well, not just the budget. Diameter, flow, head, and installation depth are all treated as inputs to a single sizing decision, so you're not choosing between "too small" and "wildly oversized."
Engineering support on the sizing itself. Tell us the borehole diameter, depth, static and dynamic water level, required flow, required head, and water quality, and Hydroman's team will work the duty point with you before you commit to a model — the same disciplined sequence (yield test, water levels, then total dynamic head) that groundwater engineers follow industry-wide, and the same logic behind standards like AWWA E101 for submersible turbine pumps used in water supply service.
Installing a Submersible Borehole Pump: What the Process Actually Involves
Check the borehole and the pump. Confirm casing diameter, total depth, static and dynamic water levels, and inspect the pump, cable, and rising main for shipping damage before anything goes down the hole.
Connect pump, motor, and cable. Couple the pump end to the motor per the manufacturer's torque and alignment specs, then secure and strap the submersible cable along the rising main at set intervals so nothing snags or chafes on the way down.
Lower the pump carefully. Guide it down the centre of the casing to avoid impact against the borehole wall, and stop at the calculated installation depth — not the bottom of the well.
Connect the control equipment. Wire in the control panel with overload, phase-failure, low-water-level, and (where applicable) earth-leakage protection, sized to the motor's actual rated current, not a generic default.
Test the system before you sign off. Verify all electrical connections, confirm correct motor rotation direction, check valves and pipework for leaks, then run the pump and confirm the flow rate, discharge pressure, and running current all sit where the duty point said they should.
Maintenance and the Problems Worth Watching For
Most borehole pump complaints trace back to one of a short list of causes: low flow, low pressure, unexpectedly high power draw, a motor that keeps tripping, sand coming through in the discharge, or a pump that's simply blocked.
Extending service life is less about heroics and more about consistency: never let the pump run dry, keep sand content within the rated limit rather than treating it as a suggestion, avoid excessive start-stop cycling (which stresses the motor and check valve far more than steady running does), keep an eye on the water level relative to the pump's minimum submergence, and check running current periodically — a slow upward creep in current is usually the earliest warning sign of wear, long before the pump audibly struggles.
Submersible Borehole Pumps vs. Other Types
There's a fair amount of confusion in the "types of borehole pumps" search results, so here's the short version.
Submersible borehole pumps run fully underwater, motor and all — this is what almost every modern deep borehole installation uses, because there's no practical suction-lift limit to fight and no noisy above-ground pump house needed.
Surface-mounted borehole systems, by contrast, sit above ground and draw water up through suction, which limits how deep they can effectively pull from and makes priming and noise real considerations — workable for shallow wells, impractical for genuine deep-well duty.
Multistage vs. single-stage is really a head question, not a general-quality one. Multistage pumps win decisively wherever real head is required — deep wells, long vertical lifts, pressurized distribution. Single-stage submersibles still make sense for shallow, high-flow, low-head jobs where you're moving a lot of water a short vertical distance and don't want to pay for stages you don't need.
And to answer the search itself directly — "submersible pump" describes how the pump is built and installed (motor and pump end underwater); "borehole pump" describes where it's used (in a drilled well). The 150TQJ(R)5-150 is both at once: a submersible pump purpose-built for borehole service.
Before you request a quote, it helps to have these on hand — borehole diameter, borehole depth, static and dynamic water level, required flow rate, required head, water temperature, water quality (including sand content if known), and available power supply. Hand over those numbers and Hydroman's engineers can confirm the right stage count, motor rating, and accessory list before anything ships — which is the difference between a submersible borehole pump for sale that fits your well and one that just fits a generic spec sheet.

What is a borehole?
A borehole is a narrow, drilled well used to reach groundwater below the surface, typically cased with steel or PVC pipe, and used for water supply, irrigation, or industrial abstraction.
How do I know what size pump is correct for my application?
Not from motor power alone. Work from borehole diameter, required flow, required head, and the water level — in that order — rather than picking a pump by horsepower first.
What percentage sand content can this pump handle?
The 150TQJ(R)5-150 is rated up to roughly 0.01% sand content by volume (around 100 g/m³). Water carrying more abrasive solids than that will shorten pump life regardless of the model, and a pre-filtration step is worth the cost if your borehole runs sandy.
How do I know what pump materials are correct for my application?
That comes down to water quality: pH, chloride content, iron and manganese levels, temperature, and abrasive solids all point toward different material choices. Share a water analysis if you have one — it changes the recommendation more than any other single input.
Can this pump run dry?
No — no submersible pump should run dry, briefly or otherwise, since the motor depends on the surrounding water for cooling. Low-water-level protection in the control panel is there specifically to shut the pump down before that happens.
What control equipment is available for this pump?
Control cabinets with overload and phase-failure protection, low-water-level cutoff, soft starters, and VFD options for variable-speed operation are all available depending on motor size and application.
Is the 150TQJ(R)5-150 suitable for irrigation?
Yes — its flow and head range covers most drip and pivot irrigation duty points, and it's commonly specified for exactly that. Confirm your system's actual required flow and pressure and we'll match the stage count to it.
What's the difference between a borehole pump and a submersible pump?
They're not opposing categories — "borehole pump" describes the application (a drilled well), and "submersible pump" describes the design (motor and pump end running underwater). Most modern borehole pumps, including this one, are submersible by design.
