Hydroman 150THY90-6P Pump Description
For contractors operating Hidromek excavators, the challenge of underwater slurry removal often requires costly dedicated dredges. The solution lies in a Hydraulic Dredge Pump for Hidromek Excavator System that converts your existing machine into a high-capacity dredging unit. Specifically, the 150mm 6 Inch Outlet Hydraulic Submersible Pump offers impressive solids handling. This 90kW Excavator Driven Vertical Dredge Pump operates fully submerged, acting as a Submerged Hydraulic Pump for Underwater Dredging Applications. As a Heavy Duty Slurry Pump for Hidromek Excavators, it tackles the toughest materials without relying on electricity. This combination eliminates external power sources and maximizes your Hidromek’s hydraulic efficiency. In this guide, we explore why this pump redefines mobile dredging.
Hidromek excavators—such as the HMK 300LC, HMK 370LC, or HMK 230LC—are renowned for their high-pressure, variable-flow hydraulic systems. The Vertical Hydraulic Pump with 150mm Discharge directly taps into this existing power source. No generator, no electric cable reel, no separate hydraulic power pack. You simply connect the pump to the excavator’s auxiliary hydraulic circuit using quick couplers, and the machine’s own oil flow drives the pump motor.
Why does this matter? Traditional electric submersible pumps struggle in deep water or remote locations where power access is limited. They also pose safety risks in wet environments. In contrast, a Vertical Hydraulic Pump with 150mm Discharge runs entirely on hydraulic oil, making it intrinsically safe and capable of operating at depths exceeding 30 meters. The 150mm (6-inch) outlet moves large volumes of slurry—typically up to 450–600 cubic meters per hour, depending on the excavator’s hydraulic flow. For Hidromek owners, this means turning a standard crawler excavator into a powerful dredging machine in under 15 minutes.
Moreover, the vertical orientation allows the pump to sit directly above the suction inlet, minimizing clogging and enabling it to handle irregular solids like gravel, broken rock, and fibrous sludge. Unlike horizontal pumps that require priming, this vertical design self-primes instantly once submerged.
High Efficiency Hydraulic Dredge Pump for Excavators: 4 Design Features That Deliver Reliability
The Hydroman® 150THY90-6P is not just another attachment—it is engineered specifically for High Efficiency Hydraulic Dredge Pump for Excavators applications. Below are four design features that set it apart:
1. Hydraulic-Driven Agitation System
Instead of relying on the suction alone, the pump integrates a side-mounted agitator impeller at the intake base. This agitator rotates independently (powered by the same hydraulic circuit) and actively breaks up settled sand, clay, or tailings into a fluid slurry before it enters the pump. This feature increases solids capture ratio by up to 40% compared to non-agitated pumps, especially in compacted sediments.
2. Wear-Resistant High-Chrome Alloy Construction
The wet end—including the impeller, wear plate, and volute casing—is cast from high-chrome white iron (hardness >58 HRC). This material withstands the abrasive assault of quartz sand, sharp gravel, and crushed ores. Field data shows that a High Efficiency Hydraulic Dredge Pump for Excavators with high-chrome components lasts three to five times longer than standard cast iron pumps in similar slurry duties.
3. Double Mechanical Seal with Oil Bath
Leakage is the #1 killer of submersible pumps. The 150THY90-6P uses a tandem silicon carbide mechanical seal arrangement, with the seal chamber filled with dielectric oil. This design prevents water or slurry ingress even when the pump is fully submerged for days. A built-in seal failure sensor (optional) can alert the operator via the excavator’s cab warning light.
4. Compact, Bolt-On Mounting Frame
The pump attaches directly to the excavator’s boom or arm using a universal pin-style bracket. No custom fabrication needed for most Hidromek models. The hydraulic hoses route along the boom with protected sleeves, and the total weight (approximately 380 kg) remains well within the lift capacity of any medium-to-large Hidromek excavator. This plug-and-play approach reduces downtime between jobs.

Sand Mining and River Restoration
In riverbeds and lakes, sediment accumulation reduces water flow and disrupts ecosystems. Traditional dredgers are large, expensive to mobilize, and require permits for transport. By mounting the 90kW Excavator Driven Vertical Dredge Pump onto a Hidromek excavator, you gain a nimble, self-propelled dredge. The excavator walks into the water (with proper undercarriage protection), extends its boom, and the pump begins suctioning sand or gravel from depths up to 15 meters (depending on boom length). The material is then discharged through a floating pipeline to a dewatering screen or stockpile area.
Real-world example: A contractor in Indonesia used a Hidromek HMK 310LC fitted with this pump to extract 120 tons of river sand per hour, achieving 70% solids concentration by weight. The built-in agitator eliminated the need for a separate water jetting system, cutting fuel consumption by 25% compared to a conventional dredge.
Mine Tailings and Settling Pond Reclamation
Mining operations generate vast quantities of tailings slurry that settle in ponds. Over time, these ponds lose storage capacity and pose environmental risks. The 90kW Excavator Driven Vertical Dredge Pump allows mine operators to reclaim valuable minerals or simply relocate tailings to a new containment area. Because the pump is hydraulic, there is no spark risk from electric motors—critical in explosive dust environments. The excavator can work from the pond’s edge, lowering the pump on a long stick, or even sit on a floating pontoon. The high-chrome impeller easily handles leftover grinding media (steel balls) and rock chips that would destroy standard pumps.
One copper mine in Chile reported reducing tailings pond cleanup time by 60% after switching from a rented electric dredge to a Hydroman® pump on their own Hidromek excavator. The ability to reposition instantly without shutting down power cables was cited as the biggest productivity gain.
Frequently Asked Questions About the Heavy Duty Slurry Pump for Hidromek Excavators
Q1: Can the Hydroman® 150THY90-6P run on any Hidromek excavator model, or are modifications required?
A: The pump requires a minimum hydraulic oil flow of 160 L/min at 250 bar. Most Hidromek excavators from the 230LC series upward (including HMK 230LC, 290LC, 310LC, 370LC) meet or exceed this spec. For smaller models like the HMK 140LC, you may need to check auxiliary flow settings. No permanent modifications to the excavator are necessary—just add quick couplers for the hydraulic lines and a return line filter if not already present. Hydroman® provides adapter brackets for all common pin sizes (40mm, 45mm, 50mm).
Q2: How deep underwater can the Heavy Duty Slurry Pump for Hidromek Excavators operate?
A: The pump itself is rated for continuous submersion up to 30 meters (100 feet) of water depth. However, the practical limit is determined by your excavator’s boom and arm length plus the length of hydraulic hoses. Using a long-reach boom (e.g., 15m total reach), you can dredge at depths of 12–15 meters. For deeper applications, you can mount the pump on a crane or a specially designed submersible frame—just ensure the hydraulic power unit (your excavator) stays above water. The pump’s seals and bearings are pressure-compensated, so deeper operation is possible with optional modifications.
Q3: How does this pump compare to a standard electric submersible slurry pump in operating cost?
A: Over a typical 2,000-hour working year, the Heavy Duty Slurry Pump for Hidromek Excavators often proves 30–50% cheaper to operate. Here’s why: no electricity costs (the excavator already burns diesel for movement), no separate generator rental or purchase, no long power cables that get damaged, and no downtime waiting for electricians. Maintenance is limited to replacing wear parts (impeller, wear plate) every 800–1,200 hours depending on abrasiveness. A comparable electric pump of the same capacity would require a 110–132 kW motor and a 250 kVA generator, plus a soft starter—easily doubling the initial investment.
