Back Pull-out Facility

All pumps incorporate the “back pull out” facility allowing the remove of the complete rotating element without disturbing the pipework. This features enables quick and simple maintenance to take place.

 

Interchangeability

Many of the components are interchangeable, this features resulting in a reduction in spares requirements, and an initial cost saving.

 

Excellent Bearing Housing Design

Incorporated with lifting eye to simplify removal of the rotating element during maintenance, “safe guards” are installed to prevent rotating shaft from human reach while in operation.
