Description

Figure 2 (Page 3) shows the main components of the Portable MicroPur ge Pump and
the assembled pump. The body twists of f for quick change of the disposable poly-
ethylene (PE) bladder . The bladder simply pushes on to provide a leak-tight seal for
most applications without the use of clamps.
The cap of the pump twists off for full disassembly of the inlet and outlet check
valves and the tubing connection components.
The pump uses 1/8" O.D. tubing for compressed gas supply and 1/4" O.D. tubing for
the sample discharge. Tubing connections to the pump are made via push-in fittings
built into the top of the pump.
The push-in connections provide excellent pull out strength when used with QED
tubing, so that use of a support cable is not required. Ho wever a connection eye is
provided on the top of the pump and tubing for use of a cable when preferred. The
connection eye is threaded into the top plate of the pump and can easily be removed
or reinstalled as desired. The push-in fittings on the SamplePro pump are designed
to provide at least 25 lbs. combined pullout strength when used with QED tubing.
QED is not responsible for loss of the pump if non-QED tubing is used.
