Positive displacement lobe pumps with safety valve design

PUMP INTRODUCTION

Safety valve built-in type positive displacement rotor pump

The positive displacement lobe pumps must be protected from excess pressure when they are operating. BONVE lobe pumps can be fitted with a stainless steel safety valve or a safety by-pass. The valve protects the pump and prevents excessively high pressure arising in the circuit. It reduces the differential pressure between suction and discharge, but not the maximum pressure within the plant. Safety valve is an important method to protect the pump, to prevent over-pressure damage to the pump.

PUMP FEATURES

We pursue excellence, more than ten years of dedicated research and development, only to allow customers to obtain long service life, high precision, strong versatility, customized lobe pump.Below are the positive displacement lobe pumps main features.

Long service life: gap is kept between the rotor and the rotor, the rotor and the pump body; no friction; simple assembly and disassembly, easy maintenance and cleaning, and few wearing parts; energy saving, low failure rate, reliable sealing and low noise.

High precision: all main parts including the pump chamber, rotors, gear box, shafts, bearings are processed by CNC.

Strong versatility: we offer the targeted seal type and rotor type as per the specific product to be transferred. The rotors and seal types are interchangeable.

Customization: according to the customers installation condition, pump port direction can be horizontal and vertical. And the connection types can be screw and clamp type, etc.

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.
