Ejector Pumps

 

 

Ejector pumps are sewage handling pumps that are required when wastewater cannot flow to its destination by means of gravity at a velocity of at least 2 feet per second. There are two basic types of ejector pumps. One is the vertical suspended type where the motor is mounted on the cover of the basin, supported by its shaft connected to the pump housing inside the basin. The second type is the close-coupled submersible, where the motor is connected directly to the pump housing and impeller by a short shaft and is submerged completely inside the basin.
