OMEGA’s model HHP-10K 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.
SPECIFICATIONS 
Output Ranges: 0 – 10000 psi (0 to 700 bar) 
Gauge Connection: 3/8 BSP (¼ NPT adapter included)
Process Connection: ¼ BSP (¼ NPT adapter included) 
Materials: SS, Polyurethane, Anodized Hard-Coat Aluminum, PTFE, and nitrile
Weight: 3 lbs (1.36 kg)
GUIDELINES FOR USE
:
§ Do not exceed 10,000 psi (700 bar) as this is the pumps maximum pressure.
§ Each pump includes a built in pressure release valve to limit the maximum pressure. This 
is factory pre-set to 10,000 psi.
§ The HHP-10K pump has 3/8 and ¼ BSP ports. In order to use NPT fittings, the required 
NPT to BSP Parallel thread adapters need to be installed (Included BSP to 1/4 NPT 
Adapters).
§ Do not use of thread sealant paste or tape on the adapters. Bonded washers (included) 
are required to ensure proper seal. To seal the adapters, simply hand tighten and snug up 
with a wrench. Do not over-tighten.
§ Use with distilled water or mineral based hydraulic oil.

PUMP OPERATION
1) Remove the Fill Cap and fill reservoir to the recommended level with the appropriate 
fluid and replace plug.
2) Connect hose fittings and calibrators to adapters.
3) Connect master instrument to pump via the top port.
4) Connect instrument under test to flexible hose/gage adapter.
5) To prime the system, twist the knurled knob marked “release”. Squeeze the handles 
together and release. Twist the knob once again. Repeat 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.
6) Operate handle several times to build pressure. Please note, once pressure starts to 
rise, pressure can increase very rapidly. Warning: Do not exceed maximum operating 
pressure indicated on the pump label.
7) Careful uses of the release valve and fine control enable a controlled release of 
pressure, essential for calibration purposes.
8) 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.
9) RESERVOIR FLUID LEVEL: If the fluid level in the reservoir falls considerably during 
use, a partial vacuum can be created in the reservoir which may affect the pump 
performance. To avoid this, simply allow air to enter the reservoir by partly unscrewing 
the Fill Cap.
10) SEAL REPLACEMENT: Dependent on the frequency of use, the Main Piston Seal (and 
others) will need replacing. Call factory for replacement seal.
MAINTENANCE
No routine maintenance is required. A periodic check of system calibration is recommended. The 
pump is not field serviceable and should be returned if repair is needed (field repair should not 
be attempted and may void warranty). Be sure to include a brief description of the problem plus 
any relevant application notes. Contact customer service to receive a return goods authorization 
number before shipping.
