Product Description

High-Efficiency Stainless Steel Rotary Lobe Pump for Fluid Transfer 


Bonve is the Chinese leading manufacturer of rotary lobe pumps in China since 2001. Its pumps are widely used for food and chemicals. Based on this, our pumps are mainly devided into two series, sanitary lobe pump and chemical lobe pump. All the contact parts are made of stainless steel, so we called them stainless steel pump. Bonve has the most advanced pump technology on it and produce the biggest flow upto 400m3/h. Now, Bonve pumps are covered each sector to transfer liquids. There is a liquid, there is a Bonve pump.

The pump are mostly driving by the electrical motor, so we called it as electrical motor pump. Surely, you can match the motor by yourself to save the cost, so we supply the bare shaft pump. Below are the pump details. 

Product Description

Bonve rotary lobe pumps are designed based on the exploration of more than 3,000 fluids in various industries. They are particularly pumping for high viscosity, high solids, sanitary and corrosive fluids. The pumps are widely used and have long service life benefits from the below features.

1. Interchangeable rotors, multi connection type and installation type, fit for various applications.
2. Targeted seal for specific application, ensure a reliable sealing.
3. Compact structure, easy assembling and disassembling.
4. Maintenance in place (above the models of 80BV), easy cleaning, CIPable and SIPable.
5. Few wearing parts, low maintenance.
6. All main parts proceed by CNC, high precision fabrication.
7. No contact between the rotors, rotors and pump chamber.
8. Multi bearings with separate arrangement, high pressure resistance. 
9. Axis key synchronous adjustment, no rotor collision problem.
10. The flow can be controlled at will by frequnecy inverter.
11. Capable to pump the viscous medium from 1cp to 2million cps.  
12. Capable of pumping mixture of gas, fluid and solid medium.

Working principle

Bonve lobe pumps basically consist of two lobe rotors, which rotate synchronously driven by a pair of synchronous gears in the gearbox. The rotors are driven by the main shaft and sub-shaft to rotate in a synchronous reverse direction, which changes the pump capacity, builds up high vacuum and discharge pressure, thus an efficient pumping is formed. Gap is kept between the rotors and between the pump casing, no friction, long life, no damage, no physical and chemical reaction to the pumped products.

Pump advantages


Bonve has an advantage over lobe pump that no other company can match.

1.Rotor:The error of the rotors processed by CNC is extremely small. The unique rotor perfectly seals the inlet and outlet of the pump. The vacuum degree of the pump is up to -0.095MPA. The rotor material and type can be selected according to the characteristics of the pumped product.

2.Shaft: The transmission shaft is processed by CNC machining center, whice has characteristics of high precision, high bending strength and strong wear resistance.

3.Pump cavity: The pump cavity is sealed by a pump cover that can be opened quickly, enabling quick maintenance of the pump. The pump body is processed by CNC maching.

4.Gears:High-precision, High-Standard synchronous gears have good meshing, smooth transmission, low noise, and excellent bearing capacity.

5.Mechanical seal:The seal material and type are selected according to the characteristice of the pumped product, to ensure zero leakage, no pollution, and more environmental production.

6.Bearings: Six bearings arranged in a separate arrangement increase the concentricity of the pump operation, enhance the bearing capacity of the shaft and make the pump running more stable, thereby increasing the service life of the shaft and the mechanical seal.

7.Gear box: The gear box is processed by CNC, with high precision, hogh concentricity and strong versatility.

8.Spindle:We use splines the bearings and spindle, makes the pump less likely to slip. The high-precision spline makes the pump run more smoothly, and the service life is much higher than that of its peers.
