Application:
These series of rotary pumps is used to transfer high viscosity media like asphalt, the pumps transfer different media of viscosities, it is depended on the rotary technical structure and material, they can transfer media as:
Temperature from -10℃ —200℃,
The temperature of the type NYPO.78,and type NYP2.3 is from -10℃ —80℃
The range of media viscosity is 1.0cSt—300,000CST

Features:
1. The rotors structure offer powerful pumping power
2. No noise during the pumping working
3. Self-priming water
4. The displacement has the liner function with the rotary speed of rotors, by adjusting speed to change the displacement
5. The rotary pumps are generated by after researching lots of industrial pumps, many advantages of other industrial pumps are used into these asphalt high viscosity pumps
Structures:
The rotary pumps are constructed by rotors, shaft, pump body, front cover, support, seal, bearings, packing seal is implemented when the pump need to transfer high temperature and high viscosity medias, there is temperature layer between the pump body and front cover for melting solid material.
Laifu offers various kinds industrial pumps such as internal gear pump, external gear pumps, screw pump, centrifugal pumps, and rotary pumps.
