MECP500
Pneumatic Hand Pump
Operating Instructions
The MECP500 Pneumatic Hand Pump is a compact, lightweight,
portable, hand-operated pressure and vacuum pump. When a digital
calibrator is added the unit can be used to calibrate or check pressure
measuring devices in the field. No external power or high pressure bottles
are required. The MECP500 is completely assembled and ready to connect
to the pressure device to be calibrated. Calibration is quick and simple
since the pump is taken directly to the pressure device. This pneumatic
pump provides a source of air pressure, 0-500 psig (600 psi max.), or
vacuum, 0-28" Hg.
1. Isolate the device to be calibrated. CAUTION: Do not connect to
high pressure sources. Safe operating procedures must be
exercised to avoid personal injury and damage to the calibration
system.
2. Connect the pump and calibrator to the pressure device to be
calibrated. Make sure the connection is pressure tight and be certain
to use Teflon tape to prevent leakage.
3. Turn the knurled knob on the needle valve clockwise to close.
NOTE: Hand tighten only to prevent damage to the valve seat.
4. Using a small screwdriver, set the shuttle valve to "pressure or
vacuum". Note that "P" and "V" are stamped on the sides of the pump
body.
5. Squeeze the handles until the desired or approximate pressure is
obtained. Additional force is required as the pressure is increased.
6. The pressure can be decreased with the needle valve.
7. The pressure can be "fine tuned" with the vernier knob. To increase
pressure, turn the vernier knob clockwise. Turning the vernier knob
