Pedro Gil BPG rotary piston volumetric booster pump

Volumetric booster with rotating pistons

A guarantee of controlled flow and sustainable performance, vital for industrial applications where any interruption is unacceptable..

‍

The operating principle is based on two synchronized rotors rotating in opposite directions inside a precision-machined cast iron body. These rotors operate without contact with each other or with the housing, which eliminates any risk of internal wear and allows operation without lubrication in the compression chamber. This design guarantees perfect cleanliness of the fluid conveyed, a key point for air and process gas applications.
