Butterfly rotor pump:
With butterfly rotor,it is superior to other rotor pump when transferring material with high viscosity and larger grain and effectively transports extremely stiff material.
Single butterfly curved rotor pump(grain rotor pump):
This pump series are specially designed to transport material with large grain.Its unique shape and curve makes it more outstanding compared to other pumps in delivering material with large grains.It effectively prevents grains from clashing,which is the first choice of pumps transferring material with grains.

Model Flow per 100
Adjusting speed
Liquid(L/H) Power(Kw)

The flow in the table refers to the data tested taking water as the medium.
Adopts stepless speed regulator or frequency transformer to adjust the speed, with speed
adjustable in 200-900rpm.
The motor power should be increased when delivering high viscosity liquid,
For mediums that flow slowly, suggest delivering in the inlet with pumps of matched flow .
The data in the table is subject to change without notice.See the actual products for the right data.
