4" hydraulic powered submersible trash pump

The HDI TP40 is a compact hydraulic submersible trash pump engineered for high-volume liquid transfer in demanding environments. Lightweight yet rugged, the TP40 efficiently handles water, sand slurries, gravel, and sludge—making it ideal for construction sites, industrial cleanup, or emergency response.

This direct-drive centrifugal design requires no priming and can run dry all day without damage. With no belts, pulleys, or gears, all moving parts are self-lubricated by hydraulic fluid for virtually maintenance-free performance.

Key Features:

• Handles up to 30% solids – Ideal for sand, gravel, sludge, and slurry
• Run-dry capable – Submersible centrifugal pump design with no priming required
• Durable construction –Steel bowl, Ductile iron impeller, Aluminum wear plate
• Maintenance-Free Direct Drive – No seals to grease or drive components to adjust
• Flush-face hydraulic couplers – Thread directly into SAE ports (no NPT threads to leak)
• Discharge Outlet: 3" male NPT outlet fitted with standard 4" cam-lock adapter

Hydraulic Specifications:

• Flow Range: 7–9 GPM
• Max Pressure: 2,000 PSI
• Max Back Pressure: 250 PSI
• Hydraulic Return: Must discharge into an open, non-pressurized reservoir (open circuit only)

Important: Back pressure in the hydraulic return line can damage the pump shaft seal—ensure skid steers or other power sources meet open-return requirements.

Ideal For:

• Construction dewatering
• Trench and foundation cleanup
• Slurry and sludge pumping
• Septic and oily wastewater
• Flood response and stormwater control

The TP40 is your go-to solution when durability, mobility, and efficiency matter. Whether you're pumping mud, gravel-laden water, or just need a reliable site dewatering pump, the HDI TP40 gets it done—fast.
