Overview
INTRODUCTION
Thank you for purchasing a Hydraulic Hand Pump from Crystal Engineering. This pump provides you with a portable pressure source for calibration of high
pressure gauges, recorders, switches, and transmitters. The built-in variable volume gives you precision at any pressure.
There are two pressure ports on the pump. Mount a Crystal Gauge or Calibrator directly to the front of the pump, connect the spare port directly to the device
being tested, and you have a complete eld pressure calibration system. A 1m (3ft.) CPF high pressure hose, and CPF Female to1⁄4" Male NPT is included,
along with a convenient plastic bottle for hydraulic uid. A rebuild kit is available (P/N 2940), so that you can service the pump yourself, if necessary.

any petroleum based hydraulic oil, light weight motor oil, or mineral oil. Do not use brake uid or synthetic oils; they may
crack the polycarbonate reservoir or cause swelling or decomposition of the "O" rings.

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
!
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 (polytetra uoro-ethylene) tape on the threads of any pressure 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 o er a wide variety of CPF ttings to
permit using the sy
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 uid or synthetic oils which may attack the polycarbonate
reservoir, or cause swelling or decomposition of the "O" rings. Your uid can be stored in the convenient plastic uid dispensing bottle
(supplied with the pump). See Priming the Pump on page 3 for more information.

PRIMING THE PUMP
1 Put a small amount of uid in the Reservoir; enough to cover the bleed-o valve hole in the
bottom of the reservoir.
The easiest way to ll the Reservoir is to remove the Vent Plug, and use the uid bottle to squirt
uid into the Reservoir.
2 Turn the variable volume handle clockwise until it stops turning.
3 Open the Bleed-o
Fluid and trapped air should circulate out of the Bleed-o Valve hole back into the Reservoir.
4 Squeeze the Handle repeatedly until no air is seen coming out of the Bleed-o
5 Fill the Reservoir, in prepation for use.
Note: We recommend that you keep the pump primed.

TROUBLESHOOTING
The Pump Will Not Generate Pressure
Reason
The pump has probably lost its prime.
Solution
If it will not prime, remove the reservoir and insert a small wire into the inlet check valve hole to make sure the valve moves freely. Squirt oil into the inlet
check valve while squeezing and releasing the handle. Then reinstall the reservoir and prime the pump. Another possible reason for pump failure is dirt under
one of the check valves, which may prevent uid from owing freely back into the reservoir. We recommend removing, cleaning, and reinstalling the check
valves. See the diagram below for proper check valve reassembly.
Outlet Check ValveInlet Check Valve
Support 5
The Pump Does Not Hold Pressure
Reason
The pump may be leaking internally or externally.
Solution
If pressure goes up when the handle is squeezed and drops when the handle is released, there may be dirt under the outlet check valve. Remove the brass
plug, clean the check valve, and reinstall.
