Master Vapor Pump MVP-6CFM Explosion Proof Recovery Pump

Master Vapor Pumps MVP-6CFM Vapor Recovery Pump can recover a staggering 1lb of vapor per minute. Each system is certified and made in the USA for superior quality. This pump is 3rd party certifiable with your system, UL listed and FDA compliant. The mvp recovery pump uses no oil allowing for zero contamination of your product.

You can run this explosion proof diaphragm MVP pump with 100% duty cycle, 24/7 without overheating or issue. The dual-diaphragm pump is electrically powered by an explosion-proof motor, and has a working pressure of 350psi.

Performance Factoids:

    • Recover LP-Gas vapor at over 6 CFM (cubic feet per minute)
    • Recover butane at up to 1 LB/Min (pounds per minute)
    • Recover and re-condense butane at over 12 GPH (gallons per hour)
    • Maximum pumping outlet pressure: 60 PSI (4.1 bar) continuous, 70 PSI (4.8 bar) intermittent
    • Maximum pumping inlet vacuum produced: 27 InHg (0.91 bar)
    • Maximum pumping speed: 190 CPM (cycles per minute)
    • Pump static withstand pressure rating: MAWP 350 PSI (24 bar)
    • Materials: pressure section: stainless steel; diaphragms: FKM; reed valves: stainless steel
    • Optional PTFE diaphragms kit available
    • Process gas temperature range: FKM -40-275F (-40-135C); PTFE +40-220F (4-104C)
    • Recommended FKM replacement schedule: every 1000 hours running time
    • Air temperature range for motor/gearbox operation: 32-104F(0-40C)


Pump Head Charge:

    • Motor is coupled to diaphragms with patented gas pressure charged chamber
    • Pumping outlet pressure runs about 10 PSI lower than the charge gas pressure level
    • Non-reactive CO2 gas is used to charge the pump head
    • CO2 gas is safer than air for driving the pump
    • CO2 gas is non-flammable and non-explosive with LPG (should a diaphragm ever leak)
    • CO2 gas regulator with gauges is provided with pump assembly
    • CO2 tank is operator provided (cannot ship filled tanks) – from any welding supply store
    • Pump charge gas supply: standard (#20) 5 LB tank of industrial CO2
    • Typical CO2 gas usage: <0.2 SCFH (very little); estimated life of charge gas tank: 1 year
    • Pump charge gas pressure range: continuous 5 to 70 PSI (1.4 to 5.5 bar); to 80 PSI intermittent
