Pneumatic Oil Boost Pump is a machine which will increase the pressure of a fluid. This pump boosts water pressure and, in many cases, improves the flow rate. This pump is designed to help pumping systems achieve higher flow rates and overcome high system head. This pump is used in water systems or applications that have low waste contamination.Pneumatic Oil Boost Pump works just like a fan. A fan has blades that spin around to increase air movement, and a booster pump has an impeller inside that increases water flow and pressure in the same fashion.
