SEWAGE EJECTOR PUMPS VS. SEWAGE GRINDER PUMPS

SEWAGE EJECTOR PUMPS

Sewage Ejector Pumps are considered high volume/low pressure submersible solids handling pumps. Sewage Ejector pumps do not have grinding blades. They use spinning impellers that intake the raw sewage through the bottom of the pump and force it under pressure out of the outlet and into the discharge pipe. Sewage Ejector pumps are designed to handle up to 2’’ diameter solids.

The most common application for a Sewage Ejector pump is to move raw sewage from a residence to a septic tank or gravity flow sewer main. These units normally have a 2’’ discharge and range from 4/10 HP all the way up to 5 HP. Sewage Ejector pumps can pump high volumes of sewage (up to 580 Gallons Per Minute). These pumps are designed for short pumping distances (under 750 feet) and can handle head pressures of nearly 75 feet.

SEWAGE GRINDER PUMPS

Sewage Grinder Pumps are considered high pressure/low volume submersible solids handling pumps. Sewage Grinder pumps have grinding blades that grind the raw sewage into a slurry before passing it through the discharge line. Sewage Grinder Pumps are designed to handle the same type of materials as a Sewage Ejector Pump.

Sewage Grinder Pumps are commonly used when pumping from a residence to a pressurized sewer main. Because a pressurized sewer main is under pressure from another sewage pump, it takes a pump that can overcome that pressure to pump liquids into that main. Sewage Grinder Pumps have the ability to do this, pumping liquid at nearly 60 P.S.I.  Sewage Grinder pumps normally have a 1-1/4’’ discharge and range from 2 HP and up. They generally will pump low volumes of sewage (30 Gallons Per Minute or less), but can push it over longer distances (thousands of feet) and can handle head pressures of nearly 130 feet.

It is not recommended to use a Sewage Grinder Pump when pumping sewage from a residence to a septic tank. The sewage gets ground up into such a fine slurry that once it enters the septic tank the solids do not ever separate from the liquid and get passed on to the secondary system. This will quickly ruin your subsurface leaching field. Sewage Grinder pumps also require a minimum of 20 to 30 feet of head pressure in order to operate correctly. Using a Sewage Grinder pump in a low head situation (very little vertical lift, short horizontal run) will quickly burn up the pump. Most manufacturers rely on that minimum amount of head pressure to keep the RPMs of the electric motor down. When that head pressure is not existent, the motors spin faster causing them to pull more amperage and run hotter which will eventually lead them to burn up much faster.
