The East Hills Instruments Magnum Pro MP calibration pump is the most reliable, rugged pressure and vacuum calibration pump for calibrations up to 100 psi. The "Schrader" valve totally eliminates failure caused by the vent valve failing.

The East Hills Instruments Magnum Pro MP calibration pump feature unique push-on hoses and fittings. In addition, a swivel keeps the hose from tangling.

An optional hose kit is available with purchase of the East Hills Instruments Magnum Pro MP calibration pump so that a tee is not necessary when connecting a sensor and calibrator. A special non-dispersing lubricant makes the first stroke as easy as the others and eliminates wear caused by the grease migrating to the ends of the stroke. Construction is so strong that the East Hills Instruments Magnum Pro MP calibration pump can be repeatedly dropped on a concrete floor without damage!
