Weight 15 lbs


MVP-6CFM Explosion Proof Recovery Pump 

(This item may carry up to a 2-4 week lead time)

Our Master Vapor Pumps MVP-6CFM Vapor Recovery Pump is designed for hydrocarbon extraction processing and is electrically powered by an explosion-proof motor to ensure the complete safety of the user. For safe, efficient, and thorough recovery, this pump is the best choice available. The total max output pressure is 60psi.

This dual-diaphragm pump is built with stainless steel wetted parts. It has a max allowable working pressure of 350 PSI, and each unit Recovery pump is certified and made in the USA.


Performance Factoids:

  • Recover LP-Gas vapor at over 6CFM (cubic feet per minute)
  • Recover butane at up to 1 LB/Min (pounds per minute)
  • Recover and recondense 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 industrail 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
