ComboPump Operation Manual

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 fingertips. 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 field 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 confident 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.
