High Viscosity Rotary Pump

 High Viscosity Rotary Pump

Application:
The rotary pump are used to transfer high viscous media, viscosity is 1.0cst - 300,000cst
(but, NYP0.78, NYP2.3 types pumps 1.0cst-10,000cst),
The range of temperature of the media transferred is -10℃-200℃
(the pump types NYP0.7and NYP2.3 is from -10℃ to 80℃)
The high viscosity pumps are widely used in the chemicals, petroleum refinery factories, medicine manufacturing, dye, paint, and food industry, these rotary pumps are self-priming pumps.

Structures:
This series is new designed pumps with different material to make internal parts, the new material is corrosive resistance and heat resistance, for high temperature viscous media transferring the high temperature resistance packing seal is used in to seal the pump shaft, packing seal and temperature, there is insulation layer heating by steam to melt the solid media

Laifu offers various kinds industrial pumps such as internal gear pump, external gear pumps, screw pump, centrifugal pumps, and rotary pumps.
