Each Magnum Pro calibration pump uses our unique patented design, utilizing a Schrader valve instead of a needle valve, dual O-rings on all pistons as well as other enhancements. These innovations have earned our calibration pumps the reputation of being indestructible.
Produces pneumatic pressure and vacuum to check calibration of gauges, switches, transmitters, and recorders. The contoured cushioned handles provide extra comfort while preventing the pump from sliding. The over-sized check valve provides smooth operation throughout the output range while the dual o-rings on all pistons ensure zero leakage. Patented Mash proof vent valve comes standard on all MVP-600s (No Needle Valve) and a non-oil based lubricant is used on all moving parts.
