In this video, Pump Products expert Nick explains the difference between sewage pumps and grinder pumps. This is a question that we get often and it's simple to remember the difference. Sewage pumps can transport water with waste solids up to 2" in diameter; grinder pumps use a cutter to grind waste solids into a fine slurry.
