DG series horizontal single-suction multistage centrifugal pumps are suitable for supplying clean water of other liquids with similar physical & chemical properties with water. This series pumps are developed by the pump trades and its effeciency is 4% higher that of the old products. They are recommended by the nation as a kind of ernergy saving products.
For type DG pumps, the medium tempreture is not excess 130℃ and they can be used for bolier water supplying, water flooding in oil-fields and in other spots.
Allowed suction pressure≤0.6MPa (suction nozzle pressure must be indicated in order)
Capacity: 3.75cbm/h-185cbm/h
Head: 69m-684m
Construction: the pumps have vertical inlet and outlet
Drive: the pumps are directly driven by motor through flexible coupling. The rotation is clockwise viewed from motor end.
Shaft seal: soft packing are used to seal the shaft or mechanical sealing the shaft sleeve can be renewed.
Bearing and balance: rolling bearings are used to surpport the pump and the bearings are lubricated by grease. Mainly axial force is balancing disc and others are absored by rolling bearings.
