Overview:
 

It's multistage section centrifugal pump, the excellent hydraulic models are high-efficiency, energy-saving, and have wide performance range, operating safety&steady, low noise, long life and installing&repairing is very convenient and etc. It can deliver heat water, oil, corrosive or wearable medium by changing the material, seal or adding cooling system.

Type DF pump can deliver the corrosive liquid without solid particle, which temperature is from -20ºC~150ºC.

Features

It has compact structure,less vibration,high efficiency, mechanical seal,all parts touched with water can be made of stainless steel.

It's special used in low pressure,all parts touch with liquid can be of  stainless steel materials,cast iron materials is mainly for the clean water and physically chemically similar to clean water liquid,cast steel materials is for the mine water liquid with small liquid as it can anti abrasive, well,SS materials is for the corrosive liquid, for the sea water, it will be 316L SS or even better materials.
