In fact, in most cases a Sewage Ejector pump is the much better option. In summary, not all sewage handling pumps are Grinder Pumps and a Sewage Grinder pump is not always necessary to pump raw sewage. You have a low vertical distance to lift the water (under 70 feet).When pumping sewage short distances (750 feet or less).When pumping sewage to a gravity sewer main.You have a high vertical distance to lift the water (minimum of 30 feet)īelow are the scenarios when a Sewage Ejector Pump will work best:.When pumping a very long distance (1000 feet or more).When pumping to a pressurized sewer main.You should only use a Sewage Grinder Pump when one the following apply to your application: 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. 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. 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. The units without internal capacitors require a special control panel with built in capacitors to operate the pump. Basin Extension Model: RM18x12EXT 24 x 12 in. Basin Extension Model: RM18圆EXT 18 x 12 in. These require no control panel for operation. 1/2 HP Pre-Plumbed Sewage Pump System Model: JPACK30S-550T 1/2 HP Pre-Plumbed Sewage Pump System Model: JPACK30S-550T-HD 1/2 HP Pre-Plumbed Sewage Pump System Model: JPACK45S-550T-HD Basin Extensions 18 x 6 in. The most commonly used forms are with internal capacitors. Each model comes in two forms, one with internal capacitors and one without internal capacitors.
They are available in both Little Giant and Ashland Pump brands. The second is to pump over extremely long distances, or up over very high elevation changes.Īll of our Grinder Pumps start at 2.0 HP and have 1-1/4’’ NPT discharges. The first is to pump from a residence into a shared pressurized sewer main. There a couple of applications that these pumps are normally used in. These pumps can grind up sewage into a slurry and pump it at a very high pressure to its destination. Sewage Injectors are necessary when public sewer lines are at a depth of 2 to 4 n below the street level SEWAGE INJECTOR SEPTIC TANK A Septic Tank is a It is used to liquefy and receptacle or vault precipitate solid waste used to collect organic purifying odorous waste discharged from materials the house sewer. However, Sewage Grinder pumps are much more powerful. Sewage Grinder pumps are designed to handle raw sewage pumping jobs, just like the Sewage Ejector pumps.
