The PGS-40 pressure calibration hand pump is used in conjunction with a precision digital pressure indicator or dial gauge for pressure testing or calibrating pressure transmitters, pressure gauges, pressure safety valves and switches and any kind of pressure device installed in a process plant.

The PGS 40 pressure test pump generates pressures and vacuum by simply squeezing the hand scissors and incorporates a volume adjuster ( fine control) for the precise setting of the desired pressure test point.

A valve selector is used for switching between pressure and vacuum mode.

To protect the unit under test and the reference pressure indicator, the PGS 40 calibration hand pump include as standard an adjustable over-pressure protection ( stroke adjustment) which limits the its pressure generation.
