Technical sheet

These pumps move water no clean-water centrifugal would tolerate: wastewater with solids, dewatering excavations full of mud and sand, sumps, basement and flood drainage. They are submersible and work inside the liquid.

Solids passage is what decides

The specification that determines whether a wastewater pump is fit for a job is not power but what size of solid it will pass. An impeller that jams every three days is not a pump, it is a recurring maintenance visit.

That is why the discharge is large relative to the power — 2″ to 6″ NPT across this series. A bigger diameter is not there to move more water; it is there so that what comes with the water gets through. Reducing that line at installation with an adapter "to make it fit" is the most common cause of blockages in a newly commissioned system.

Dewatering and wastewater

The same machine covers two different jobs. Dewatering is clearing accumulated water — an excavation, a flooded basement, a pit after rain — where the duty is intermittent but urgent. Wastewater is continuous service in a sump, starting and stopping on a float for years.

Continuous service puts the weight on duty cycle and seal robustness; dewatering puts it on speed and on starting submerged without priming.

Thirty-nine configurations cover 0.5 to 25 hp, single phase at 110/220 V and three phase at 220/440 V.
