Features
For safe and reliable operation please spend a few minutes reading the following instructions.
!
WARNING: To prevent damage to the pump and possible injury, never connect your pump to a pressure source greater than 35 MPa
(5000 PSIG, 350 bar). Turn off , or isolate, all pressure-generating equipment from the pressure tap prior to connecting
the pump.
Note: Since handpumps are small displacement pumps, be sure to minimize the volume to be pressurized.
 
CONNECTION PORTS
Your pump has two connections; A 1⁄4" female NPT pressure port for a reference gauge or calibrator and a CPF female connection. Always
use PTFE (polytetrafl uoro-ethylene) tape on the threads of any pressure fi ttings installed into the NPT port. Connect your reference gauge,
or plug the 1⁄4" female NPT port prior to priming or using your pump. As for the hose connection, we off er a wide variety of CPF fi ttings to
permit using the system with most commonly used fi ttings.
 
FLUID OPTIONS
We recommend any petroleum based hydraulic oil, lightweight motor oil, or mineral oil. Water can also be used, but it will accelerate the
wear of "O" rings, and may cause some sticking of the piston. Do not use brake fl uid or synthetic oils which may attack the polycarbonate
reservoir, or cause swelling or decomposition of the "O" rings. Your fl uid can be stored in the convenient plastic fl uid dispensing bottle
(supplied with the pump). See Priming the Pump on page 3 for more information.
