MH-10KT
Hydraulic Calibration Hand Pump
Operating Instructions
The MH-10KT Hydraulic Calibration Hand Pump utilizes a fully adjustable stroke control that allows for quick priming, easy pumping
and fast pressure generation up to 10,000 psi (700 bar). The ergonomically engineered handles provide extra comfort, while the patented
triple filtration system ensures pump operation in spite of dirty conditions. The shatterproof reservoir and stainless steel construction
guarantee leak free operation. The pump has oversized check valves to provide smooth controlled operation.

as necessary until system is fully primed and low pressure is indicated on either the master or test instrument. This feature can be changed at
any pressure.
Operate handle several times to build pressure. Please note that once pressure starts to rise, it will rise very rapidly. Be sure to not exceed the

maximum operating pressure indicated on the face of the MH-10KT.
7. Careful use of the release valve and fine control enable a controlled release of pressure, essential for calibration purposes.

To adjust the pressure relief valve, release the pressure and turn the valve counter clockwise 1/16 turn and then proceed to re-pressurize. Repeat the process if further reduction is necessary
If the fluid level in the reservoir falls considerably during use, a partial vacuum can be created in the reservoir which may affect pump per-
