PRODUCING POSITIVE PRESSURE

1) Connect one of the Model PPP-3P’s ports to the

auxiliary port is not used, it should be securely
plugged.

2) Set the brass fine pressure adjustment knob on
the top of the pump to the mid-travel position as
indicated by the line cast into the pump body.

3) Turn the black discharge knob on the side of the
pump fully clockwise. Do not overtighten.

4) Squeeze the actuating levers to generate
pressure. At pressures above 150 psig the le­vers should be squeezed harder and more quickly
at the end of the stroke. Additional force is
required to open the discharge valve due to
higher line pressure.

5) Use the discharge and fine pressure knobs to

WARNING

Even nominal pressure values can generate
extreme force if fitting or tubing failure occurs due
to improper installation or usage. Since the Model
PPP-3P is capable of generating pressures over
100 psig, it is imperative that all pressure
connections and test procedures be done by
qualified service personnel, according to standard
engineering practices, to prevent possible
personal injury or equipment damage.

clockwise to generate the desired negative

pressure (to -2 psig).

TEMPERATURE CONSIDERATIONS

Since the pressure change of a contained
volume of gas is directly proportional to absolute
temperature, temperature control is critical when
using the Model PPP-3P with any high-resolution
measuring device. Tubing should be kept away
from heat sources (i.e., lamps, operating
electronic equipment, excessive hand contact,
etc.) as well as from heat-dissipating structures
(i.e., open windows, air conditioning vents,
ventilation ducts, etc.) to minimize temperature
variations that might induce measurement error.

Air is compressed when the Model PPP-3P’s
actuating levers are squeezed. This
compression causes some heating of the air as
it is forced into the system. Consequently, a
noticeable decrease in pressure—caused by the
cooling of the newly compressed air—may occur
immediately after cessation of pumping.

LUBRICATION

The Model PPP-3P is lubricated at the factory
and under normal operating conditions should
not require additional lubrication. If lubrication
is required, invert the pump and apply two drops
of a light-grade machine oil to the piston rod near
the base of the pump body. Do not over-oil.

LEAK PREVENTION AND DETECTION

In order to obtain maximum pressure indication
stability, leaks must be avoided. It is strongly
recommended that either Teflon® tape or
commercial pipe sealant be used at all tapered
fittings and connections. If Teflon® tape is used,
care must be taken that the proper amount is
applied. Excessive tape may fray and cause
plugging of relief valves, orifices, nozzles, etc.
Overuse of pipe sealant may cause similar
problems.

External equipment should also be checked
carefully for leaks. Process connections, flange
bolts, and vents must be tightly closed. Defective
gaskets, leaking valves, and damaged
diaphragms are all potential sources of leaks.

For detection of very small system leaks, the
traditional soap bubble method may not be
sufficient. Halogen leak detection devices may
be required when using highly sensitive pressure
calibration equipment.
