Rotor pump, also known as high viscosity pump, universal transfer pump, has a wide range of applications, because in the process of operation, there is no friction between the rotor and the rotor in the cavity of the food-grade rotor pump, so the service life is also very long.

Screw pump in the use of the process can not be empty operation, there must be liquid conditions to work.

Protection devices such as safety valves should be installed on the outlet pipeline of the rotary lobe rotor pump. Once the outlet channel of the rotary lobe rotor pump is blocked, the safety valve can be opened to relieve pressure.

1. Rapid change of ambient temperature 2. Emptying, cavitation or holding pressure for a long time, resulting in seal damage and leakage of cam rotor pump unit.3. The return flow is too large, which leads to the sediment at the bottom of the suction tube side container (tower, kettle, tank, pool), which damages the seal.

High viscosity rotor pump in daily use pay attention to the preservation of electric oil pump should be placed in a dry, clean and corrosive gas-free environment. Save each part and replace the same part, when disassembling and inspecting the high viscosity rotor pump, you should save each part, and pay special attention to the flameproof surface of the flameproof part can not make its damage, including insulation gasket and casing

The rotary lobe pump is a kind of volumetric pump which can change the volume of the pump through a pair of synchronous rotating rotors, resulting in high vacuum and discharge pressure to realize fluid transportation. There are many kinds of rotor pumps, among which the most common types are stainless steel rotary lobe pump, high viscosity rotor pump and food transfer pump.
