What Is a Sewage Pump?
What exactly is a sewage pump? A sewage pump, in simple terms, is used to transfer sewage solids and liquids from one place to another. They are the ideal solution where there is no gravitational flow available.
The pump itself works to collect, and then move sewage to its designated exit point – whether that be a connection to the sewer system, or a septic tank is located uphill.
Sewage pumps are usually located submerged in the sewage basin which is why sewage pumps are also often referred to as a submersible sewage pump. Sewage pumps can normally be found in a bathroom basement.
A sewage pump can be used in one of 3 different modes: manual, automatic or dual mode. A manual pump bypasses the switch and is plugged straight into the mains socket.
However, it is advised that the sewage pump should not be used in manual mode as there is the possibility the sewage could overflow.
An automatic pump is plugs into a float switch meaning that the pump will only work when the float switch is activated. In dual mode, the sewage pump can both used in both manual and automatic.
How Does a Sewage Pump Work?
Sewage pumps allow for solids to pass through without clogging up the pump.
The way that it works is that when the pump is turned on, the motor rotates the impeller that then creates a centrifugal force which pushes the wastewater into the impeller. It is then ultimately discharged into the main sewer system or septic tank.
Different Types of Sewage Pumps
There are 3 types of sewage pumps are that can be used. These are effluent pumps, small handling pumps (sewage ejector pump) and grinder pumps.
The most commonly used in smaller buildings is the effluent pump. While both solid handling pumps and grinder pumps have to allow solid waste to pass through the pump effluent pumps do not.
Effluent pumps tend to pump clearer liquids due to the solids being broken down in the septic tank.
Without having to handle the sewage solids, it allows the effluent pump to be more efficient in pumping high levels of waste than other types of sewage pumps.
Grinder pumps, unlike effluent pumps, can pump raw sewage away. Grinder pumps act like waste disposal grinders in that they cut up and grind up sewage solids into small pieces before being pumped away into the sewer system.
Solid Handling Pumps (Sewage Ejector Pump)
Sewage ejector pumps just like grinder pumps can pump solid sewage away. Sewage ejector pumps do not have grinding blades. The sold handling pump pumps sewage waste from your property to either a septic tank or main sewer system.
What is the Difference Between a Sewage Pump and a Sump Pump?
Sewage pumps often get confused with sump pumps. However, the biggest difference is what each pump deals with.
Sewage pumps, as already described, deal with wastewater and solids while on the other hand, sump pumps are designed to just get rid of water in a basement that may be at risk of flooding problems.
Another difference is that the sewage pump is powered by being plugged into an electrical socket while a sump pump can be powered by both electricity and battery backup system.
