Hydraulic Pumps

Hydraulic Pumps

When it comes to the raw strength of hydraulic tools, STANLEY® hydraulic pumps are the gold standard. Our Submersible Pumps (SM series) are for use with relatively clean water and designed for pumping vaults, manholes, and other locations where high volumes of water are required to be pumped to a higher head. The close tolerance of the impeller and wear plate in this design provides the high head capacity with large volumes of water. The Trash Pump (TP series) is for liquids with solids up to 25% by volume and is ideal for water main breaks, (trenches/mud) sewage, and wastewater. The removable top plate design allows cleaning of the volute if the discharge becomes clogged. STANLEY® hydraulic pumps set the bar for performance and reliability.

Epiroc - STANLEY SM20 Sump Pump - Landscape

Submersible Pump - SM20

The STANLEY® SM20 Water Pump is a lightweight yet durable solution for a variety of pumping needs. With a capacity of 250 gpm (946 lpm) at a 10-foot head and the ability to handle solids up to 5/16 inch, it's ideal for use in vaults and manholes. Outperforming most gasoline engine-driven pumps, the SM20 eliminates the need for recoil starting, priming, or suction hoses. It can even run dry without causing any damage, offering unmatched convenience and reliability.

Epiroc - STANLEY SM50 Sump Pump - Landscape

Submersible Pump - SM50

The STANLEY® SM50 Water Pump is a reliable submersible centrifugal pump that requires no priming, making it ideal for a variety of applications. Powered by a contaminant-tolerant gear motor, it is specifically engineered for continuous high-speed operation, ensuring consistent performance in demanding conditions. The motor drives the impeller directly, eliminating the need for spindle bearings that require regular lubrication or replacement. Featuring a corrosion-resistant cast stainless steel, semi-closed impeller, the SM50 is built to withstand harsh environments. A series of advanced seals on the drive shaft effectively contain hydraulic fluid and water, allowing the pump to operate dry without risking sudden seal failure, making it a durable and low-maintenance choice for reliable water management.

Trash Pump - TP03

The STANLEY® TP03 Trash Pump is the lightest, most efficient solution for moving large volumes of liquid with up to 25% solid content. No priming is needed—just drop it in, and it's ready to work. Featuring a virtually indestructible urethane bowl, it is tough, abrasion-resistant, resilient, and impervious to petrochemical solvents, allowing it to pump a wide range of materials without damage. Its durability and ease of use make it an ideal choice for demanding tasks.

Trash Pump - TP08

The STANLEY® TP08 Trash Pump is a lightweight, heavy-duty, submersible pump capable of handling high volumes of water, sand slurries, gravel, sludge, and solids up to 3 in./75 mm. It’s self-priming, can run dry without damage, and uses just 9 gpm/34 lpm of hydraulic flow to pump over 800 gpm/3,028 lpm at a 10 ft/2.54 m head. Weighing 59 lbs/27 kg, it’s easy for one operator to handle, with durable construction featuring a steel volute, abrasion-resistant cast iron impeller, and UHMW polyethylene wear plates. Paired with the STANLEY® HP28 Power Unit, it’s perfect for high-volume dewatering and trash pump applications.
