Sewage and grinder pumps and how they work

Sewage and effluent pumps are submersible pumps that protect the motor with a sealed compartment that can be submersed into the liquid that is being pumped. Most effluent and sewage pump motors are electric and can be used in basements or any below-ground level area where sewage drains need support or have to run uphill.

Features of sewage and grinder pumps

• A grinder pump will shred and chop sewage so it is ground to a fine slurry that can be pumped through a 1-1/4’’ line.
• Most grinder pumps come with 1-1/4” discharge.
• Sewage pumps however uses a “deep vane” or “vortex” impeller to pass wastewater solids of 2” and up and come in discharge sizes of 2” and up.
• Many industrial applications run a duplex system (2 sewage or grinder pumps) which requires a control panel to alternate the pumps and has a high water alarm.
• An alarm is important to ensure that the user is notified of any required maintenance or repairs with the plumbing shutting down until the work is complete.
