The 2RP lobe rotor pump is a rotary positive displacement pump. It is suitable for transferring media with temperature from -30°C to +80°C and viscosity from 30 to 1.0 × 10⁵ cSt, including suspended liquids containing solid particles, corrosive media, and media with high sanitary requirements.
The parts inside the pump body that contact the medium are made of stainless steel. According to the different physical properties of the medium, the pump speed can be adjusted to meet process requirements.
Structure & Working Features
The 2RP lobe rotor pump mainly consists of lobe rotors, shaft seal, and gearbox. A pair of synchronously rotating transmission gears drives the lobe rotors, allowing the pump to transfer the medium through positive displacement action.
The shaft seal can be designed as a packing seal or mechanical seal according to different working conditions. The pump uses a high-strength cast iron gearbox, helical gears, and heavy-duty bearings to support long service life under suitable operating conditions.
The main part of the 3-2RP stainless steel food pump uses a cartridge-style assembly, allowing rotor clearance adjustment without disassembling the gearbox.
The O-ring material is silicone rubber. When the medium is corrosive, PTFE can be used. Viewed from the motor toward the pump, the standard pump rotation direction is clockwise.
