2" Submersible Hydraulic Water Pump

HDI SP20 Submersible Trash Pump

The HDI SP20 is a highly efficient, compact submersible hydraulic trash pump designed for dewatering construction sites. Engineered to move large volumes of liquid quickly, the SP20 is lightweight and easy to operate, making it an ideal solution for a variety of applications.

Key Features:

• No Priming Required: The SP20 uses a centrifugal design that eliminates the need for priming and allows it to run dry without damage for extended periods.
• Self-Lubricating: With a direct drive system and all moving parts being lubricated by passing hydraulic fluid, the SP20 requires no maintenance.
• Durable Impeller: The semi-closed stainless steel impeller is corrosion-resistant and capable of drawing down water to a depth of just 1 inch.
• Efficient Flow: Operates with 5-8 GPM of hydraulic oil. Please refer to the flow chart for specific details.
• Versatile Coupling: Fitted with a flush face coupler that threads directly into SAE ports—no NPT hydraulic joints to leak or weep.
• Easy Connection: The pump comes standard with a 2” female NPT output port, complete with a 2” Cam Lock fitting for secure and easy connections.
• Robust Construction: The SP20 is designed for longevity, with its corrosion-resistant impeller and heavy-duty construction that ensures reliability even in harsh conditions.

Important Notes:

• Hydraulic System Requirements: The hydraulic motor must return to an open, non-pressurized reservoir in an open circuit configuration. Back pressure on the discharge or return side of the hydraulic system may damage the shaft seal.
• Testing Information: All testing was conducted in a controlled environment using regulated pressures and flows. Field results may vary depending on specific conditions.
• Skid Steer Consideration: Users should be aware of the open circuit requirements when using the SP20 with skid steer loaders.
