Stanley SM20 Hydraulic Pump

2½" Hydraulic Submersible Wastewater Pump

Stanley SM20 Hydraulic PumpThe Stanley SM20 Hydraulic Pump is one of the lightest and most durable pumps available. Pumping 250 gpm (946 lpm) at a 10 foot head and moving solids up to 5/16 of an inch makes it ideal for vaults and manholes.

The SM20 will out-pump most all gasoline engine driven pumps. There is no recoil starting, priming or suction hose as with gas engine driven pumps. It can be run dry without damage.

Submersed into the water and with its easy hookup to a power unit, the SM20 is instantly pumping.

The standard urethane impeller is highly abrasion resistant for long service pumping gritty slurries.

The abrasion resistant cast iron inlet wear ring is easily replaced from the inlet sit of the pump.

With only a few moving parts, the SM20 is virtually maintenance free.


  • Maximum Head: 43 m
  • Maximum Flow: 82 m³⁄hr
  • Safe Hydraulic Drive can be used where electric power is hazardous or impractical
  • Operates with our HS10DH Hydraulic Power Unit


The Sterling SPP Hydraflow S4VHL Hydraulic Pump is suitable for a range of applications:

  • Sewer bypass into force mains
  • General transfer of solids laden fluids
  • Where electric power is hazardous or impractical
