Owner's manual

Omega’s 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.
