The Omega’s HPP Series precision calibration pumps are designed to provide long term reliability in harsh environments. Four models are available to cover ranges from vacuum up to 690 bar (10,000 psi). Pumps can be purchased separately or as a kit that includes a carrying case, tubing and fittings.
HPP-100 Low pressure and HPP-VAC vacuum model pneumatic hand pumps are the most dependable and rugged pump for applications up to 100 psi or 28.8" Hg Vacuum. The Delrin and anodized aluminum construction prevents body heat transfer, resulting in drift-free, accurate readings . The pump is equipped with oversized check valves in order to provide smooth and controlled operation. Dual O-Rings on all pistons ensure the pump to be leak-free. The unit includes a 2 foot long hose, 1/8 female NPT gauge fitting, and 1/8 NPT pipe plug. An optional hose kit is available so that a tee is not required when connecting a sensor and a calibrator. This pump is ideal for checking calibration of pressure or vacuum gauges, switches, or transmitters.
HPP-VAC HPP-VAC are economical pumps designed for 0 to 6.9 bar (0 to 100 psi) or 0 to -0.95 bar (0 to -28 inHg vacuum). Both models feature dual O-rings on all pistons for smooth operation with zero leakage. A "mash proof" schrader valve replaces the needle valve commonly used for the vent.
HPP-600 The HPP-600 is a pneumatic pump that can generate both vacuum and pressure. It covers a range from -0.95 bar (28 inHg) vacuum to 41 bar (600 psi) pressure. Dual O-rings, oversized check valves, and a "mash proof" vent valve ensure smooth, trouble free operation.
HPP-10K The HPP-10K hydraulic pump can generate pressure from 0 to 690 bar (0 to 10,000 psi). It is compatible with most hydraulic fluids, oils and water. A precision stroke control adjustment allows for fast priming or shorter stroke for easier pumping at high pressure. It features a shatter proof reservoir, triple filtration system and a built in pressure relief valve.
