SEWAGE GRINDER PUMPS
Sewage Grinder pumps are designed to handle raw sewage pumping jobs, just like the Sewage Ejector pumps. However, grinder pumps are much more powerful. These pumps grind up sewage into a slurry and pump it at a very high pressure to its destination. There a couple of applications that these pumps are normally used in. The first is to pump from a residence into a shared pressurized sewer main. The second is to pump over extremely long distances, or up over very high elevation changes.
All of our Grinder Pumps start at 2.0 HP and have 1-1/4’’ NPT discharges. They are available in both Little Giant and Ashland Pump brands. Each model comes in two forms, one with internal capacitors and one without internal capacitors. The most commonly used forms are with internal capacitors. These require no control panel for operation. The units without internal capacitors require a special control panel with built in capacitors to operate the pump.
GRINDER PUMPS OR EJECTOR PUMPS.... WHICH DO YOU CHOOSE?
PLEASE NOTE: Grinder pumps must be used in scenarios where there will be at least a minimum of 30 feet of head pressure put on them. If they do not have to pump against at least this much back pressure, the motor will begin to spin at an extremely high rate of RPMs causing it to burn up fairly quickly. Therefore, if you are not pumping into a shared sewer main or have less than 30 feet of head, you do want a Sewage Ejector pump not a Sewage Grinder pump.
You should only use a Sewage Grinder Pump when one the following apply to your application:
- When pumping to city sewer.
- When pumping to a pressurized sewer main.
- When pumping a very long distance (1000 feet or more)
- You have a high vertical distance to lift the water (minimum of 30 feet)
Below are the scenarios when a Sewage Ejector Pump will work best:
- When pumping sewage to a septic tank.
- When pumping sewage to a gravity sewer main.
- When pumping sewage short distances (750 feet or less)
- You have a low vertical distance to lift the water (under 70 feet)
In summary, not all sewage handling pumps are Grinder Pumps and a Sewage Grinder pump is not always necessary to pump raw sewage. In fact, in most cases a Sewage Ejector pump is the much better option. And, there are certain scenarios when you could use either type.
