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.
