Pump rotors are sealed by mechanical seals
The rotary pump consists of two rotors rotating inside the case without touching each other. As the rotors rotate, the space between the pump casing and rotors are gradually filled with product, which moves in a certain volume to the discharge hole. The pumped product generates a continuous flow due to the verified tolerances between the rotors and housing, ensuring an efficient pumping process.
