PUMP INTRODUCTION

V-inlet rotary lobe pumps/ Rotor pumps with oil lubrication

BONVE self-lubricating lobe pumps are equipped with an oil cup for their mechanical seal. The main purpose is to optimize the lubricity of the mechanical seal, so as to realize the idling of the mechanical seal in a short time and prevent the mechanical seal from dry grinding during operation.

PUMP MAIN FEATURES

The all main parts are made by CNC, which have high precision;
Simple structure, easy to clean and maintaince;
Long service life, reducing use cost;
Energy saving, low noise;
Various of drive method can meet customers’ requirement;
The transportable medium viscosity is upto 1.5 million cp, and the slurry with a solid content upto 70%;
It can transport three-phase mixture materials such as vapor, liquld and solid.

WORKING PRINCIPLE

Stainless steel pump factory

The self-lubricating lobe pumps with oil cup adopt two lobe rotors, which rotate synchronously driven by a pair of synchronous gear 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.

Note:
1. Tested medium: water. Your liquid's density, viscosity and temperature are necessary to supply when choose the pump.
2. Speed, flow rate, electrical power and pressure will be varified according to different liquid properties.
3. Port size can be changed as needed.
