CENTRIFUGAL PUMPS- DBXe SERIES

FEATURES

Casing: The casing has axial suction and top centre line delivery with self venting design. Smooth hydraulic passage ensures highest efficiency. Delivery flanges and supporting feet are cast integral with the casing.
Impeller: The impellers are of enclosed type. Hydraulic balancing of impellers is achieved by balancing holes depending upon magnitude of axial thrust. The impellers are statically and dynamically balanced.
Shaft: The shaft is supported between antifriction ball bearings. The critical speed of shaft is sufficiently above the operating speed. The shaft is critically machined and ground to maintain concentricity. It is fully protected from the liquid being handled by means of shaft sleeve and ‘O’ ring and gasket between impeller screw & impeller.
Stuffing Box: The stuffing box is sealed by either gland packing or by mechanical seal.
Bearings: Pre-lubricated grease sealed bearings are used as a standard scope of supply. Pumps with oil-lubricated bearings will be supplied against specific order.
Direction of Rotation: Clockwise when viewed from driving end.
Drive: Pumps can be driven by electric motor or engine
