Although it is pretty common to use these terms interchangeably, there is actually a significant difference between sewage pumps and grinder pumps. Both these machines work differently to dispose of raw sewage. So, let us today discuss these differences and understand which pump is appropriate in which situation. Here is a crisp guide for you.

Introduction about Sewage Pump and Grinder Pump

Sewage Pump

What is a sewage pump? In simple terms, a sewage pump is a machine that transfers sewage waste from one place to another. Residential sewage comprises soft solids that usually have a diameter of up to 2 inches.

This sewage is pushed from the sewage basin into a sewer system. The sewage pump is placed at the lowest base of the sewage basin. In other words, the pump is submerged in order to do efficient pumping. Sewage pumps are of three types:

• Manual pumps
• Dual mode pumps
• Automatic pumps

Grinder Pump

Grinder pumps are effective waste management devices that pump sanitary waste from a building to the central municipal sewerage system. This machine is used when there is no ample slope for the sewage to flow directly to the municipal system.

Waste items from washing machines, sinks, and toilets are collected into the grinder pump's tank. When the waste reaches a specific level, the machine will automatically turn on and turn it into a paste. This mix is then transferred to the municipal sewer system.
