Suggested Installation, Operation, Maintenance and Troubleshooting

The Pro-Flo

model

P100 Advanced

™ plastic has a 13 mm (1/2") inlet

and 13 mm (1/2") outlet and is designed for flows to 58.7 lpm (15.5 gpm).
The

P100 Advanced

™ plastic pump is manufactured with wetted parts

of pure, unpigmented Polypropylene or PVDF. The

P100 Advanced

™

plastic pump is constructed with a glass fiber filled PP center section.
A variety of diaphragms and o-rings are available to satisfy temperature,

chemical compatibility, abrasion, and flex concerns.

The suction pipe size should be at least 13 mm (1/2”) diameter or larger

if highly viscous material is being pumped. The suction hose must be
non-collapsible, reinforced type as the

P100 Advanced

™ plastic pump

is capable of pulling a high vacuum. Discharge piping should be at least

13 mm (1/2”); larger diameter can be used to r

educe friction losses. It is

critical that all fittings and connections are airtight or a reduction or loss
of pump suction capability will result.

CAUTION:

All fittings and connections must be airtight.

Otherwise, pump suction capability will be reduced or lost.

Months of careful planning, study and selection efforts can result in
unsatisfactory pump performance if installation details are left to
chance. You can avoid premature failure and long-term dissatisfaction
by exercising reasonable care throughout the installation process

Location

Noise, safety and other logistical factors usually dictate where
equipment will be situated on the production floor. Multiple installations

with conflicting requirements can result in congestion of utility areas,
leaving few choices for additional pumps.
Within the framework of these and other existing conditions, every
pump should be located in such a way that several key factors are
balanced against each other to maximum advantage.:

•

Access:

First of all, the location should be accessible. If

it’s easy

to reach the pump, maintenance personnel will have an easier
time carrying out routine inspections and adjustments. Should
major repairs become necessary, ease of access can play a key

role in speeding the repair process and reducing total downtime.

•

Air Supply:

Every pump location should have an air line large

enough to supply the volume of air necessary to achieve the
desired pumping rate. Use air pressure up to a maximum of 8.6
bar (125 psig) depending on pumping requirements.

For best results, the pumps should use a 5μ (micron) air

filter,

needle valve and regulator. The use of an air filter before the
pump will ensure that the majority of any pipeline contaminants
will be eliminated.

• Solenoid Operation:

When operation is controlled by a solenoid

valve in the air line, three-way valves should be used. This valve

allows trapped air between the valve and the pump to bleed off
which improves pump performance. Pumping volume can be
estimated by counting the number of strokes per minute and then
multiplying the figure by the displacement per stroke.

• Muffler:

Sound levels are reduced below OSHA specifications using

the standard Wilden muffler. Other mufflers can be used to further
reduce sound levels, but they usually reduce pump performance.

•

Elevation:

Selecting a site that is well within the pump’s

dynamic-lift capability will assure that loss-of-prime issues will

be eliminated. In addition, pump efficiency can be adversely
affected if proper attention is not given to site location.

• Piping:

Final determination of the pump site should not be

made until the piping challenges of each possible location have
been evaluated. The impact of current and future installations
should be considered ahead of time to make sure that
inadvertent restrictions are not created for any remaining sites.

The best choice possible will be a site involving the shortest and
straightest hook-up of suction and discharge piping. Unnecessary
elbows, bends and fittings should be avoided. Pipe sizes should be
selected to keep friction losses within practical limits. All piping should
be supported independently of the pump. In addition, the piping
should be aligned to avoid placing stress on the pump fittings.

Flexible hose can be installed to aid in absorbing the forces created
by the natural reciprocating action of the pump. If the pump is to be
bolted down to a solid location, a mounting pad placed between the
pump and the foundation will assist in minimizing pump vibration.
Flexible connections between the pump and rigid piping will also
assist in minimizing pump vibration. If quick-closing valves are

installed at any point in the discharge system, or if pulsation within a
system becomes a problem, a surge suppressor (SD Equalizer

)

should be installed to protect the pump, piping and gauges from
surges and water hammer.

The

P100 Advanced™

plastic Pro-Flo

equipped pump can be

installed in submersible applications only when both the wetted and
non-wetted portions are compatible with the material being pumped.

If the pump is to be used in a submersible application, a hose should
be attached to the air and pilot spool exhaust ports of the pump.
These should then be piped above the liquid level. The exhaust area
for the pilot spool is designed to be tapped for a 1/8" NPT fitting.

If the pump is to be used in a self-priming application, make sure
that all connections are airtight and that the suction lift is within

the model’s ability.

NOTE:

Materials of construction and elastomer material have

an effect on suction-lift parameters. Please refer to the
performance section for specifics.

When pumps are installed in applications involving flooded suction or
suction-head pressures, a gate valve should be installed in the

suction line to permit closing of the line for pump service.

Pumps in service with a positive suction head are most efficient when
inlet pressure is limited to 0.5

–

0.7 bar (7

–

10 psig). Premature
