Hydroman® 150TQJ(R)5-200 Submersible Well Pump Description
When you're sourcing a submersible well pump for a deep well or borehole project, you need more than a spec sheet — you need a pump that will actually hold up under continuous duty, at the depth you're working with, on the power supply you have available. The Hydroman® 150TQJ(R)5-200 is a vertical, multistage, electric submersible well pump built to lift clean water from deep wells and boreholes, and it's a pump you'll find specified across industrial water supply, agricultural irrigation, municipal groundwater schemes, and large-scale water transfer systems.
This page walks you through how the 150TQJ(R)5-200 works, what it's rated for, how to size it against your own well, and what to check before you buy — whether you're installing a new deep well submersible water pump or working through a submersible well pump replacement on an existing system.
You install this pump vertically, and it runs fully submerged below the water level inside your well casing. That's the basic principle behind every deep well submersible pump: instead of pulling water up from the surface, the pump sits down at depth, right next to the water source, and pushes it up. For the 150TQJ(R)5-200, that means:
The 150TQJ(R)5-200 pairs a submersible electric motor with a vertical multistage centrifugal pump end. The motor drives a stack of impellers arranged in series, each one adding pressure to the water as it passes through, which is how a relatively compact pump generates the head needed to lift water from real well depths rather than just a few meters. You get electric drive, fully submerged operation, centrifugal staging, and a long, slim vertical profile that's built to fit down a standard well casing.
Key Features of the Hydroman® 150TQJ(R)5-200
The "200" in the model code refers to the pump's head rating — this unit is built to deliver against roughly 200 meters of total dynamic head, which puts it firmly in deep-well territory rather than shallow-well or booster duty. If your project needs water lifted from real depth, rather than just moved a short vertical distance, this is the class of pump you're looking at. It's rated for a flow of 5 m³/h, which is a moderate, steady output well suited to farm wells, small municipal points, and industrial process water feeds rather than high-volume dewatering.
Every stage inside the pump is one impeller and one diffuser working together. Water enters the first impeller, picks up velocity and pressure, gets redirected by the diffuser into the next stage, and the cycle repeats. Because the 150TQJ(R)5-200 uses multiple impellers stacked in series rather than a single-stage design, it can build up to 200 m of head from a pump body that's only about 1950 mm long — that stacking is what makes multistage centrifugal pumps the standard choice for deep well and borehole applications rather than single-stage surface pumps.
Because the whole unit — motor and pump end — goes down inside the well, you don't need a surface pump house, a foot valve, or a primed suction line. The pump is already sitting in the water it's meant to move, which removes the suction-lift problems that limit how deep a surface pump can realistically reach.
Running submerged, cooled by the surrounding well water and shielded from surface weather and contamination, this pump is built for the kind of duty cycle that industrial, agricultural, and municipal customers actually run: long hours, minimal supervision, and a well environment that doesn't always stay perfectly clean.

These are the numbers that actually decide whether the 150TQJ(R)5-200 fits your project — flow rate against your demand, head against your well depth and system pressure, casing diameter against the pump's outer dimensions, and power supply against the 5.5 kW motor. If any one of these doesn't line up with your well, it's worth talking to a pump engineer before you order rather than after.
A surface well pump sits above ground and has to suck water up through a pipe — and suction lift is physically limited to roughly 8 meters at sea level, which is why surface pumps can't handle real deep-well depths. A submersible well pump sidesteps that limit entirely by going down into the well itself, so it's pushing water rather than pulling it.
Groundwater is drawn in through the intake screen at the base of the pump and delivered to the first impeller stage.
From there, each impeller-and-diffuser stage adds more pressure to the water column. With enough stages working in series — which is exactly what the 150TQJ(R)5-200's design provides — the cumulative pressure is enough to overcome 200 m of vertical lift plus any additional system head from pipe friction, fittings, and discharge-side pressure requirements.
Pressurized water travels up the rising main to the surface, where it feeds into a storage tank, pressure system, irrigation network, or distribution main — whatever the project calls for.
Applications of the 150TQJ(R)5-200 Well Pump
You'll typically see this pump specified for:
Industrial water supply — factories, processing plants, and production facilities that need a dependable groundwater feed for process water or utility water.
Agricultural irrigation — farm wells and irrigation schemes where a steady 5 m³/h output over long run times matters more than short bursts of high volume.
Municipal and community water supply — smaller municipal wellheads and community groundwater points where deep aquifers are the only reliable source.
Deep well and borehole water extraction more broadly, anywhere the water table sits well below what a surface pump could reach.
Large water transfer systems, moving clean groundwater into storage tanks, reservoirs, or treatment intakes before it enters a wider distribution network.
Why Choose a Submersible Well Pump for Deep-Well Applications?
Compared with a conventional surface well pump, a submersible unit like the 150TQJ(R)5-200 removes the suction-lift ceiling completely, since the pump sits at or near the water source and pushes rather than pulls.
That also means less surface infrastructure — no pump house, no priming equipment — and quieter operation at ground level, since the noise and vibration stay down in the well.
For anything beyond a shallow well, submersible centrifugal pumps are the standard approach, simply because they're the only practical way to generate real head from real depth.
150TQJ(R)5-200 Installation Guide
Before you put this pump in the ground, work through these checks:
Well diameter and pump fit. The 150TQJ(R)5-200 needs a casing internal diameter of at least 150 mm to be installed and cooled correctly — confirm your casing size before ordering.
Required flow and head. Match the pump curve (5 m³/h at 200 m rated head) against your actual demand and your well's static and dynamic water levels, plus any additional system head on the discharge side.
Installation depth. Set the pump below the well's dynamic (pumping) water level, with enough submergence to keep the motor cooled and the intake clear of the sump, following the manufacturer's minimum-submergence guidance.
Rising pipe and cable connection. Connect the discharge pipe securely at each joint, and route and secure the submersible motor cable alongside the rising main so it isn't damaged during installation or operation.
Commissioning checks. Before you leave the pump running unattended, verify electrical connections and rotation direction, confirm water level and flow, check discharge pressure, and monitor the operating current against the 5.5 kW motor's rated draw.
How to Select the Right Submersible Well Pump
Sizing a well pump correctly comes down to a handful of numbers, and getting them right up front saves you from an undersized or oversized pump later.
Start with your required flow rate — how much water you actually need per hour or per day, based on the end use (irrigation schedule, process demand, or peak household/community draw).
Then work out total head, which is the sum of your well depth, dynamic water level, required discharge pressure, vertical lift to the point of use, and friction losses through pipe, fittings, and valves. A pump rated for 200 m of head, like the 150TQJ(R)5-200, is chosen because the total of all these losses lands in that range — not because 200 m sounds impressive on its own.
Check your well casing diameter against the pump's outer dimensions (≥150 mm for this model), confirm the motor power suits your flow and head requirement (5.5 kW here), and factor in your duty cycle — industrial and municipal applications generally call for a pump built for continuous operation, not intermittent bursts.
Maintenance of a Deep Well Submersible Pump
A submersible pump is largely out of sight once it's installed, which makes a basic monitoring routine worth keeping to.
And when performance does decline, or on the schedule your maintenance plan calls for, pull the pump for a proper inspection rather than waiting for a full failure.
Submersible Well Pump vs. Surface Well Pump
| Feature | Submersible Well Pump | Surface Well Pump |
| Installation | Inside the well, below water level | Above ground |
| Deep-Well Use | Suitable for deep wells and boreholes | Limited by suction lift (~8 m) |
| Water Lifting | Pushes water upward from depth | Relies on suction from the surface |
| Surface Footprint | Minimal — no pump house needed | Requires surface housing and priming |
| Noise | Contained underwater | Audible at ground level |
| Typical Use | Deep wells, boreholes, high-head systems | Shallow wells, short-distance transfer |
Common Problems with Submersible Well Pumps
Reduced water flow is usually traced back to a falling water table, a partially clogged intake screen, worn impellers or wear rings, or the pump simply operating outside its intended curve.
Low discharge pressure can point to an undersized pump for the system's actual head, worn or damaged stages, or excessive pipe friction losses in the rising main.
Motor overheating or overcurrent often comes down to insufficient submergence for cooling, a supply voltage problem, mechanical binding, or the pump working against a load it wasn't sized for.
Pump won't start — before assuming the worst, check the power supply, the control panel and starter, the motor cable for damage, and the motor protection device, since these account for a large share of "dead pump" call-outs that turn out not to be the pump at all.
If you're evaluating a submersible well pump replacement rather than a first-time installation, a few extra questions come into play.
When is it time to replace, rather than repair? Persistent performance decline, repeated electrical faults, worn hydraulic components, or maintenance costs that keep climbing are all reasonable signals that a like-for-like repair isn't the better economics anymore.
What actually drives submersible well pump replacement cost? Rather than a single number, replacement cost is a function of several variables together: the pump model and motor power required, well depth and installation depth, the length of pipe and cable that needs replacing, any electrical or control-panel upgrades needed, and the labor involved in pulling the old unit and installing the new one. Water well pump replacement cost varies enough by site that a like-for-like quote based on your actual well data is more useful than any general figure.
Match the replacement to the existing system, not just the old pump's horsepower or discharge size. A pump that looks similar on paper but doesn't match your well's actual flow, head, and casing diameter requirements can leave you with a system that runs, but underperforms. Before ordering a replacement, it's worth re-confirming your well's flow requirement, total head, and casing diameter, the same way you would for a new installation — a submersible well pump diagram or performance curve from your supplier makes this comparison easier.
What is a submersible well pump? It's a pump designed to operate fully submerged inside a well or borehole, combining an electric motor and a centrifugal pump end in one sealed vertical unit, so it pushes water up from depth rather than relying on surface suction.
What is the difference between a deep well submersible pump and a regular water pump? A deep well submersible pump is built with multiple centrifugal stages to generate high head — 200 m in the case of the 150TQJ(R)5-200 — and is sealed for continuous underwater operation, whereas a regular surface water pump is limited by suction lift and generally can't reach the same depths or head.
How deep can a submersible well pump be installed? Installation depth depends on the specific pump's design limits, the well's water levels, and cable length, but multistage submersible pumps like this one are specifically built for the head requirements of deep wells rather than shallow ones — check the manufacturer's maximum submergence and cable specifications for your exact installation depth.
Can this pump be used for borehole water supply? Yes — the 150TQJ(R)5-200 is designed for exactly this kind of deep well and borehole extraction duty, provided your casing diameter is at least 150 mm and your flow and head requirements fall within its rated performance.
What water quality is suitable for the 150TQJ(R)5-200? This model is built for clean water applications; heavily sediment-laden or abrasive water can accelerate wear on the impellers and stages, so it's worth checking your well's sand content before installation.
How do I select the correct well pump flow rate? Base it on your actual demand — irrigation schedule, industrial process needs, or peak community usage — rather than the well's maximum yield, since running well above sustainable yield can drop the water table faster than the aquifer recharges.
How do I calculate the required pump head? Add together your well depth, dynamic water level, required discharge pressure at the point of use, and estimated friction losses through your pipe, fittings, and valves — the total is your system head, which should sit within the pump's rated performance curve.
What information is needed to select a replacement submersible well pump? Your supplier will generally want your required flow rate, total head, well casing diameter, existing pipe and cable lengths, water conditions, and available power supply — the same information you'd need for a new installation, whether you're replacing like-for-like or upgrading the system.
