Overview

INTRODUCTION



Thank you for purchasing a ComboPump from Crystal Engineering. ComboPumps are precision pressure and vacuum sources. Operate the ComboPump with

just one hand and use the pressure-balanced variable volume to precisely set pressure with just your ngertips. The extra-sensitive check valve allows for

partial strokes to easily reach your target pressure.

There are two pressure ports on top of the pump. Mount a Crystal Gauge or Calibrator directly on top of the pump, connect the spare port directly to the

device being tested, and you have a complete eld pressure calibration system.

All moving parts of the pump mechanism are protected from damage and dirt. There are no exposed springs or piston rods. The body and handle are anod-

ized aircraft grade aluminum and all moving parts are high strength, corrosion-proof plastics and metal. That’s why we are condent your ComboPump will

provide many years of no-maintenance service. If necessary, a rebuild kit is available (P/N 2802), so that you can service the pump yourself.

ComboPump Operation Manual

OPERATING INSTRUCTIONS



The ComboPump is only for use with pneumatic systems. Do not use the ComboPump with liquids of any kind.

For safe and reliable operation please read through the following instructions.

WARNING: To prevent damage to the pump and possible injury, never connect the ComboPump to a pressure source greater than 3500 kPa (500 PSIG,

!

Note: The operating pressure rating is printed on the pump body label, on the opposite side of the vent knob.

1 Connections: Your pump has two connections: two 1/8" NPT female pipe thread pressure ports (Figure 1). Always use PTFE (polytetrauoroethylene) tape

on the threads of any pressure ttings installed into the ComboPump.

CAUTION: Do not use liquid pipe sealing compounds (such as "pipe dope"). Be careful not to over-tighten ttings.

!

WARNING: Your ttings must have a pneumatic pressure rating of at least 5000 kPa (750 PSIG, 50 bar).

!

2 Setup: Connect the ComboPump to your test set-up. Move the Shuttle Valve up or down to select whether you want "Pressure Mode"

(up position) or "Vacuum Mode" (down position). Make certain the Shuttle Valve is fully up or fully down (Figure 2).

3 Vent: To close the Vent Knob turn it completely clockwise. Don't overtighten—ngertight is enough (Figure 3).

4 Calibrate: You are now ready to perform your pressure or vacuum calibration. Squeeze the ComboPump handle until the gauge displays a value close to

the desired calibration pressure or vacuum.

35 bar). Turn o, or isolate, all pressure-generating equipment from the pressure tap prior to connecting the ComboPump.

5 Adjustments: To make pressure (or vacuum) adjustments, turn the Variable Volume Adjustment Knob. Set the precise pressure (or vacuum) desired.

It is located on the bottom of the pump next to the squeeze handle (Figure 4).

6 Finish: After the test is complete open the Vent Knob to completely release pressure or vacuum. The Vent Knob can also be used to slowly bleed the system

by opening it only a slight amount and closing it once the pressure or vacuum is reached.

Note: Be sure to close the Vent Knob fully once the system is fully vented, to prevent the knob from vibrating loose when transporting the pump.
