Positive displacement lobe pumps with safety valve design
PUMP INTRODUCTION
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.
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.
