MVP Master Vapor Pump 6CFM (New & Used) FOR SALE!

I have two master vapor pump’s available for sale in Oklahoma City. One is brand new in the box and the other is slightly used. They are both in outstanding condition. The used one comes with a c02 canister and two gauges as well. They have never been rebuilt and have no issues. We just don’t need the pumps anymore as we will be switching to a different form of extraction. Both pumps already have been wired for single phase and are ready to plug in and go. I paid over $8,500 for each of them with shipping, wiring, etc. I am asking $7,000 for the new one and $6,250 for the used one (as it has had little use and comes with co2 and gauges). Pick up only in OKC. I have attached some of the specs. C1D1 compliant!


Finally the pump the industry has been waiting for. Capable of recovering over 1 pound of vapor per minute. Decrease production times, increase your profits! Electric diaphragm pump for hydrocarbon solvent extraction processing. Built in the US on Patented Technology to meet the needs of large scale extraction systems. The MVP-6CFM is 3rd party certifiable with your system, UL listed and FDA compliant. The pump uses no oil or grease thus there is no chance of contaminating the product. Capable of Continuous 100% Duty Cycle (24/7 Runtime, won’t overheat). Maintain and repair the pump with easy DIYdiaphragm changing and internal cleaning as needed. One year manufacturer’s warranty on defect or workmanship.

Master Vapor Pumps MVP-6CFM Vapor Recovery Pump is designed for hydrocarbon extraction processing. The Dual-Diaphragm pump is electrically powered by an explosion-proof motor. It is built with stainless steel wetted parts and has a max allowable working pressure of 350 PSI. Each unit is certified and made in the USA.

Performance Factoids:
