Stainless steel rotary lobe pumps for daily chemical
Bonve stainless steel rotary lobe pumps are widely used in the daily chemical industry, due to the low speed operation, the pumps are particularly suitable for the medium that is easy to foam, high viscosity, high concentration and strong abrasion. The pumped product quality does not change and cannot afford any physical and chemical reactions. There is a certain gap between the pump rotor and the rotor, and between the rotor and the pump body, without friction, and long service life. The pump has a compact structure, easy maintenance, almost no wearing parts, and low operating costs.
Typical mediums transferred:
AES, LAS, AOS, K12, glycerin, fatty alcohol, bath shampoo, skin cream, shampoo, detergent, toothpaste, pure soap, liquid soap, washing powder slurry, etc.
Work Principle
- Bi-wing rotors diagram
- Tri-wing rotors diagram
The even rotation of the rotor pair creates a vacuum on the priming side of the pump, which can be defined by the direction of rotation of the drive. This vacuum draws the liquid into the pump chamber. With further rotation, the pumped medium is conveyed past the pump wall into the pressure area. Up to six chamber charges are displaced with each drive rotation– depending on the rotor type. When the rotor is at a standstill, The pump seals off almost completely.
