Lobe pumps consist of a dosing head made of AISI 316 stainless steel and a gearbox that transmits the pressure from the engine. The motion from the motor shaft is transmitted to the rotor shaft by two gears. As the rotor pair rotates, the volume in the inlet line increases, creating a vacuum on the suction side of the pump. This vacuum draws fluid into the pump body. The fluid is transferred to the outlet line as a result of the reduction in volume at the outlet with the rotation of the rotor.
All surfaces in contact with the fluid are stainless. Lobe Pump is hygienic in accordance with food norms. Depending on the viscosity and chemical properties of the fluid, different rotor and seal options are preferred.
In MIT Lobe Pumps, the rotors move in the opposite direction. There are very precise gaps between the rotors and the body during rotation. Thus, metal parts do not corrode and do not crush the product. Lobe Pumps are especially used in processes such as CIP (Clean in Place) and SIP (Sterilise in Place) for the sterilization of the pump in the food and pharmaceutical industries.
In cases where the process is not continuous and the fluid tends to freeze, lobe pumps with internal heat jackets are used. Thus, freezing of the product in the lobe pump is prevented. Thanks to their modular design, Lobe Pumps allow easy replacement of main parts such as rotor and shaft seal.
