Series CHP Pneumatic Hand Pump
Specifications - Installation and Operating Instructions
B
ulletin TE-CHP
The Series CHP Pneumatic Hand Pump is the most dependable and
rugged pump for applications up to 100 psi or 28.8˝ Hg Vacuum. The
durable Acetel plastic and anodized aluminum construction prevents
body heat transfer, resulting in drift-free, accurate readings. The Series
CHP 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. The
Series CHP is ideal for checking calibration of pressure or vacuum
gauges, switches, or transmitters.
CAUTION
INSURE ALL GAUGES AND INSTRUMENTS TO BE CALIBRATED ARE
DISCONNECTED FROM PROCESS PRESSURES BEFORE
CONNECTING PUMP. THE MAXIMUM PUMP DESIGN PRESSURE IS
150 PSIG. CONNECTION TO A PRESSURE SOURCE GREATER
THAN 150 PSIG COULD CAUSE SERIOUS INJURY.
OPERATION
Pressure Venting Valve Cap:
The small, knurled pressure relief knob relieves pressure from the pump.
Turning the knob counterclockwise allows the system to vent in
increments as small as 0.01˝ of H2O. Do not over tighten the valve. See
Figure 1.
