Designed For Pumping Raw Sewage

Sewage grinder pumps are specialized pumps that are designed to handle raw sewage and wastewater from homes and buildings. They are used in locations where the sewage cannot be transported through traditional gravity-type collection systems.

The pump includes a cutting mechanism that grinds up the solid materials and pumps them through the system and into the main sewer line. The cutting mechanism consists of rotating blades that shred the waste into smaller pieces.

Sewage grinder pumps are commonly used in residential and commercial buildings, as well as in municipal wastewater treatment plants. They are particularly useful in areas at low elevations or where the sewage needs to be transported over long distances.

Sewage grinder pumps require regular maintenance to prevent blockages and other issues. Homeowners and building owners should have their pumps inspected and serviced by a licensed professional on a regular basis to ensure that they are functioning properly.

Grinder pumps tend to use more power than a similar sewage pump at the same flow and head. Grinder Pumps are installed in a pressure sewer system using small-diameter PVC pipes, 1-1/2 inch to 3 inches, with a wet well basin to collect the sewage. The grinder pump station collects all of the wastewater from the home or business and then pumps it to a city sewer main or directly to a septic system.
