Single face seal: using injection flushing, the washing solution is reduced second-line wax oil at about 100C, and the pressure is higher 0.05~0.15Mpa than that in the sealing cavity. Hot water (soft water) is used for rapid cooling on the outside of the gland. It can generally be used for one cycle (ten months).

Single butterfly curve type: this series of pumps are specially designed and manufactured to solve the problem of conveying large granular materials, and its unique shape and curve form enable it to have incomparable advantages over other pumps when transporting large granular materials. It can effectively avoid particle damage in the process of conveying materials, and it is the first choice for conveying materials containing particles.

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.
