Pump Selection HandbookElectric Submersible Clean-Water Pumps
Powerful Three Phase models perfect for removing water from confined areas. The compact design and high performance engineering ensures professional results for every application. Three Phase model discharge sizes range from 3” to 6”.
This submersible centrifugal pump is a heavy-duty performance minded product for moving water in multiple confined and open area applications. This very powerful, versatile, low maintenance pump is perfect for a wide range of operations supporting Contractors, Service Utilities, and Municipalities. Further, the ST41460 Series incorporates a rugged stainless steel housing, oil-filled, double mechanical pump seals, dynamically balanced high chrome impeller, and molded 33’ Power Cable with strain relief. This type of pump requires a Control Box to provide safe operations and safety shutdowns such as thermal & voltage overload protection. Further, the Control Box would permit float switch (if required) connections.

CB1456
Control Box
Control Box
A Control Box is required to
provide overload safety shut
downs that are thermal &
voltage related, and to assist in
powering float switches. MQ
offers the control box CB1456 to
support the ST41460.
ST41460 Series - Pump Curve
As elevation (head) decreases, volume capacity increases.
When using any pump, avoid operating on the edges of the pump curve.
The center of every pump curve represents the pumps maximum efficiency.
