Sewage Pump
Pumps
that can handle liquids other than water are classified as sump pumps,
effluent pumps, grinder pumps or sewage pumps. This classification is
done by the largest particle size they can manage. For example, sump
pumps can handle small solids. The largest particle size an effluent
pump will handle is about 0.5 inch in diameter. A sewage pump will pump
up to 2-inch-diameter solids. The sewage will pump higher flow amounts.
Sewage pump is not the same as grinder pumps. Grinder pumps grind the
solids into slurry before they are pumped, while the solids pass through
the sewage pumps.
Types of Sewage Pumps:
There are two basic types of sewage pumps:
- Vertically suspended ejector pump : This pump features a
motor that is mounted on the cover of a basin and is supported by a
shaft that is connected to the pump housing inside the basin.
- Close-coupled submersible ejector pump : This pump uses a
motor that is connected directly to the pump housing and impeller by
a short shaft and submerged completely inside the basin.
Applications of Sewage Pumps:
A Sewage pump is used in a variety of applications such as:
- Commercial Application
- Industrial Application
- Maritime Application
- Municipal Application
- Wastewater Treatment Application
Uses and Features of Sewage
- Sewage pumps are used when sewage cannot flow to its destination
by means of gravity at a velocity of at least 2 foot per second.
- Sewage pumps are used to move sewage from buildings to sewage
systems and from sewage systems to treatment plants.
- Sewage pumps are used to pump effluents, semi-solids, and small
solids in a variety of applications.
- These pumps are typically made of durable materials such as
stainless steel.
- Sewage pumps can move media either horizontally or vertically,
depending on the direction of the pump stator and rotor assembly.
- There are continuous duty sewage pumps which maintain performance
specifications at 100% duty cycle.
- There are run dry capable sewage pumps that can operate without
pumped fluid or external lubrication for an extended period of time.
- Some sewage pumps include a backup battery, level control device,
thermal overload protection, grinding mechanism, control panel, or
suction.
- Some sewage pumps are close coupled, explosion-proof, corrosion
resistant, self-priming or portable.
- Specifications for sewage pumps are maximum discharge flow,
maximum discharge pressure, inlet size, discharge size and
horsepower.
- Power sources for sewage pumps are AC, DC, compressed air,
gasoline, diesel fuel, hydraulic systems, natural gas, steam, water,
and solar energy.
- Pumps that do not include a power source typically provide a
drive shaft for connection to a motor.
