Overview:

DL series of pump is a single suction, multistage stage type, vertical centrifugal pump, flow range of 5 ~ 350m³/h, head range of 22 ~ 300m. It is one of the preferred products for industrial and civil water supply, heating and fire protection systems. Changing the material of the flow parts can transport corrosive media (such as seawater, etc.) or oil products. The relative position of the inlet and outlet of the pump can be in different forms, when the user has no special requirements, the factory according to the inlet and outlet in the same side (0 "one (type) supply.

The shaft seal has two forms of soft packing seal (graphite ring) and mechanical seal. Not into the cooling water, medium maximum temperature 80ºC; Through cooling water cooling shaft seal parts, medium maximum temperature 130ºC.

Main parts of the manufacturing materials: water inlet section, middle section, outlet section and other pressure parts, ordinary cast iron, ductile iron or stainless steel; Impeller cast iron, cast copper or stainless steel; Shaft one carbon steel or stainless steel.

When the pump is used for the fixed fire feed pump, in order to avoid the rust of the rotor parts caused by long-term stop of the pump, the parts that may rust are treated with rust prevention.
