electric motor driven ballast pump
electric motor driven ballast pump
Our end suction centrifugal pump is specialized in pumping water , liquid, chemical substances, etc. With compact structure , its working diameter ranges from 50mm to 300 mm, each model of our product has 4-5 impellers with different sizes, the rotation speed is 1450rpm, 1750rpm, 2900rpm, 3500rpm for optional. This circulation for air conditioner, sewage treatment and other fields.
DA is used for handing clear water or the liquids similar to the water physically and chemically finding the applications for water feed and supply service in mine, plants and towns, air -conditioning, extinguishing and irrigation.
In spite of the same specification, the pump’s performances vary with the diameter of the impeller. (Indicated with the block letters A, B and C in the type.)
The pump is simple in structure, reliable in performances, small in size, low in power consumption, convenient in maintenance of good cavitation proof.
