Product Details

DAYLIFF DS submersible multistage centrifugal pumps are specially designed for water supply for water supply from boreholes. They are manufactured to the highest standards that gives high energy efficiency, dependable perfomance and long service life in the most demanding of applications.

FEATURES

All metal parts are made of 304 stainless steel, except for the shaft, which is made of 431 stainless steel to give years of trouble free operation.
Heavy duty stainless steel discharge head with built-in check valve for long life and ease of installation.
Motor specification are according NEMA standards
High quality shaft bearings providing low friction and high wear resistance.
Stainless steel strainer to restrict the entry of sand and other extraneous material.
High efficiency oil filled motors with non- toxic oil meeting all installation conditions.
Single phase pumps are supplied with a separate control box which incoporates an isolator, run indicator light thermal overload protetion and starting capacitor with auxiliary terminals for control probes, pressure switch or float switch can be connected directly to the mains power.
