3RP series rotary lobe pump is a multi-purpose two-way positive displacement pump manufactured by our company with advanced technology from Germany. The professional manufacturing technology and manufacturing precision of the products are close to similar products in Germany. It is suitable for conveying suspensions containing soft solid particles, corrosive media and suspensions. The temperature range of conveying medium is -30~130℃, and the viscosity range is 30cst to 1.0×105cst. Stainless steel is used for the parts contacting with medium. The rotational speed can be adjusted according to the physical properties of the conveying medium.The pump is made of two synchronous rotors/lobes. Rotors are driven by a pair of synchronous gears in the gearbox. Two rotors are rotated in the opposite direction driven by the main and auxiliary shafts, which causes the volume of the pump to change, thus forming a higher vacuum and discharge pressure. This kind of pump is especially suitable for delivering hygienic fluid and corrosive high viscosity fluid.
The rotor lobe pump relies on two synchronously rotating rotors that generate suction (vacuum) at the inlet during the rotation. Thereby sucking in the material to be conveyed. Both rotors split the rotor chamber into different spaces. Then operate in the order of 1-2-3-4. The medium is delivered to the discharge port. In this cycle, the medium (material) is continuously transported out by the source.

1. There is a certain clearance between the rotor and the rotor, no friction coefficient, so the pump has a long service life.
2. Easy to install and disassemble, easy to maintain and clean, less wearing parts.
3. High efficiency and energy saving, stable transport, low failure rate, no leakage sealing, low noise.
4. Conveying medium viscosity ≤2,000,000 Cp, can convey slurry containing 70% solids.
5. It can convey gas, liquid and solid three-phase mixture materials.
6. With Vfd, the flow rate can be adjusted at will, and it can be used as an ordinary metering pump.
7. If necessary, we can add heating jacket for the pump.
8. Temperature range: -50 °C to 250 °C.
9. Type of inlet/outlet connection: flange connection, threaded connection, quick connection.
10. Seal type Mechanical seal and packing seal.
