The SM50 Sump Pump is a submersible, centrifugal type pump that requires no priming.

It has the capacity to draw down water to a depth of 3.5 inches and can handle water containing up to 10% solids.

  • The SM50 can draw down water to a depth of 3.5 inches
  • Putting the SM50 in a sump will allow it to pump all but 3.5 inches of water remaining in the sump.
  • The pump will handle clear water and water containing up to 10% solids.
  • Ccontaminant-tolerant gear motor uniquely designed for continuous highspeed operation.
  • Drives the impeller directly meaning there are no spindle bearings that require periodic lubrication or replacement. 
Run Dry

A series of seals on the drive shaft effectively keep hydraulic fluid and pumped water where they belong while allowing the pump to be run dry without sudden seal failure. 

Ease of Use
  • The SM50 is fitted with dripless flatfaced HTMA quick couplers for easy connecting and disconnecting of the pump and hydraulic system.

  • The water outlet is 3-inch pipe thread fitted with a 3-inch groove fitting to which can be connected a cam hose end fitting. 

  • Access to the pumping chamber for cleaning requires the removal of only two capscrews.
  • The motor with the impeller attached is then easily removed from the pump casing. 

The cast stainless steel, semi-closed impeller resists corrosion. 


The integral screen effectively keeps solids larger than 3/8 of an inch out of the pump.
