The East Hills Instruments Magnum Pro MP calibration pump is the most reliable, rugged pressure and
vacuum calibration pump for calibrations up to 150 psi. The "Schrader" valve totally eliminates failure
caused by the vent valve failing. East Hills Instruments Magnum Pro MP calibration pumps are leak-free
due to double O-rings and no-needle valves, and virtually never need rebuilding. The Delrin housing
eliminates heat transfer so the readings don't appear to drift.
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. If the hose is damaged, simply cut off the end and
reinsert it into the fitting. 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!
Each East Hills Instruments Magnum Pro MP calibration pump includes a pump and one hose assembly
with a 1/4" NPT female end. The East Hills Instruments Magnum Pro Pressure Calibration Kit includes
the calibration pump, an easy-to-read analog gauge with 1% accuracy, case, and hose to connect to
item being tested. The MP-PK and the MP-VK kits are easy to use and handy for field work.
