Master Vapor Pump 150


The MVP 150 is a certified LP-Gas recovery pump specifically designed for Butane, Butane/Propane, or pure Propane vapor recovery. The motor is Explosion-proof and rated for C1D1 areas.
It is available in both three-phase and single-phase models and can operate 24/7 without the need for an air compressor. CO2 gas is used to charge the pump-head and must be supplied by the operator.
