![]() The pump needs to be powerful enough to push the water up and away from your building. If the head height offers a lift of 20 feet, but your basement or lowest area is 30 feet below the drainpipe, the head height is not sufficient. In some constructions, this means you’re sending water from the top floor to the basement and out of the building to the sewers. Sewer lines usually run from the building into the sewers at the lowest level of a building. Head height is the distance (vertically) from the lowest level of the wastewater at the pump to the high point where it exits the building for sewer lines. Look for oil-filled, sealed motors that don’t require a lot of maintenance. You want a clog-free design on the impeller. Many have cast iron bodies with stainless steel cutters to grind the materials into small pieces. You also need to look at the type of materials the grinder pump is made from. ![]() Ensure you have this type over a horizontal discharge requiring a 90-degree pipe section for the wastewater to travel upward. Most have a vertical pipe that comes out of the top. Otherwise, systems use a float to turn the pump on and off when needed.Ĭheck the grinder pump’s discharge design. How does the pump work? For a commercial sewage grinder pump, you may need a control panel setup. If it can handle 6,340 gallons per hour, it would manage an average of over 100 gallons per minute. You’ll know this by the max flow rate that’s given in terms of gallons per hour. If your business has upwards of 100 gallons of wastewater each minute, you want a pump that handles that much sewage. If you own a brewery with its own small wastewater treatment plant, you’d need a grinder pump that can handle any grains or hops that make it through filtration.Ĭheck the pump’s max flow rate. The faster it does this, the better it is to prevent backups or clogs. Higher RPMs help the pump grind solid materials into a slurry. #2 – The Grinder’s Revolutions Per Minute (RPM) The right size pump lowers your maintenance and repair costs over time. You have to make sure you’re installing a pump that can meet your wastewater demands. A pump with less power is more likely to become overwhelmed and need repairs or replacement. In a building with multiple bathrooms or kitchens, this is important. A commercial grinder pump has a more powerful motor that’s often 2 HP or higher, and the RPMs usually are in the area of 3,500. Many residential grinder pumps range from 0.5 HP to 1 HP and have an RPM of around 3,000. It handles more wastewater, so the pump needs to be equipped to handle the higher capacity. These are the things you need to consider when you start researching your options.Ī commercial sewage grinder pump will be different from a sewage grinder pump you’d use at home.
