MP-P Pressure Calibration Pump

Features a Delrin® plastic handle that prevents body heat transfer from interfering with readings, as well as an oversized check valve for smooth operation. The dual o-rings on all pistons ensure zero leakage. MP-P and MP-V have been in service for over a decade and can now be found in over two thirds of all power plants. Both models will out perform any manufactured pump in it's category.

No IssuesReview by Fred Sartwell - Ascend Cantonment, FL
The Magnum Pro pumps are the best. No issues at all. East Hills Instruments offers great customer service. (Posted on 11/16/2016)
Great Pump & Customer ServiceReview by Russ Pritchatt - Scheck Technical Services
The first time I received the Magnum Pro pump I had an issue. I called the toll free number on the pump and within a matter of only a few days the pump was repaired and back in service. They even paid to ship it back at no charge. This experience was truly “quibble free”.

BTW the pump and East Hills Instruments are my new best friends. I wish other companies could learn from them. (Posted on 6/20/2013)
