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
