Pre-Operation - Pumptec 107SS Series Operating Instructions And Parts Manual

Pumptec Operating Instructions and Parts Manual
splashing. The pump must never be installed on a vertical
surface with the pump head higher than motor, like a capital
letter "T", for example.

PRE-OPERATION

INLET CONDITIONS
CAUTION!
DO NOT STARVE THE PUMP OR RUN DRY.
Temperatures above 130°F will require a pressurized inlet to
avoid cavitation and seal damage.
DISCHARGE CONDITIONS
Open all valves in system prior to operation to avoid excessive
load on motor and system from a pressure spike. Follow the
instructions of proper system design. Refer to supplier if
assistance is needed.
PRESSURE REGULATION
Verify pressure regulation devices are operating correctly.
NOZZLES
Nozzles create pressure in most systems, and the nozzle size
becomes larger with use. Larger nozzles decrease system
pressure. Verify the quality of nozzles prior to operation.
MOTOR SHAFT ROTATION
CAUTION!
Motor shaft rotation must always be
counterclockwise to assure proper function of pump otherwise
the warranty may be void.
PUMPED LIQUIDS
Some liquids may require a flush between operations or before
storing. For pumping liquids other than water, contact your
supplier.
OPERATION
GENERAL OPERATING INFORMATION
Pressure is often created by forcing a volume of fluid (flow)
through a specific size hole (nozzle). Additionally, pressure can
be created by pumping into a non-expanding chamber. Pressure
is measured and stated in pounds per square inch or PSI.
Flow is created based upon the pump displacement and speed
(RPM) of the motor. Pump plunger size affects flow based upon
the same RPM. The faster the motor speed, the greater the
flow. Flow is measured and stated in gallons per minute or GPM.
The pump, driven by a motor or engine, draws fluid through a
set of valves into the pumping chamber and the fluid is then
3
forced out of a set of valves to exit the pump. The back-and-
forth movement of the plunger in the sealed pumping chamber
creates the suction and discharge actions.
Once the fluid has exited the pump it must be controlled until
it exits the nozzle or reaches the place it needs to go. This
control is achieved via the use of system components such as
an unloader or regulator. Theses pumps are positive
displacement pumps, which provide a specific amount of fluid
constantly while operating. This volume of fluid must be
directed out thru a nozzle or back to a tank because it cannot
be stopped completely without creating excessively high
pressure and risk of damage to the pump, components,
property, or person. It is recommended a safety device such
as a regulating valve (regulator) be installed directly on the
pump head as protection in case of the failure of another
component. Pressure switches can be used to automate pump
operation, but they must have a pressure regulating device
installed as a safety device.
Fluid can enter a pump either from a filtered tank or pressurized
fluid line.
It is common to use a tank with pumps that are mounted above
the pump. Filtration is important to maintain proper function of
the pump and system. The extent of filtration may be more
extensive based upon the application of the pump such as
misting with ultra-fine nozzles.
INLET CONDITION CHECKLIST
Inadequate inlet conditions can cause serious malfunctions
even in the best designed pumps. Surprisingly, the simplest
things can cause the most severe problems or go unnoticed to
the unfamiliar or untrained eye. REVIEW THIS CHECKLIST
BEFORE OPERATION OF ANY SYSTEM. Remember, no two
systems are alike so there can be no ONE best way to setup a
system. All factors must be carefully considered.
INLET SUPPLY
should exceed the maximum flow being
delivered by the pump to assure proper performance.
• Open inlet shut-off valve and turn on water supply to avoid
starving the pump. DO NOT RUN PUMP DRY.
• Avoid closed loop systems especially with high temperature,
ultra-high pressure, or large flows. Conditions vary with
regulating/unloader valve.
• When using an inlet supply reservoir, size it to provide
adequate liquid to accommodate the maximum output of the
pump, generally a minimum of 6-10 times the GPM. However,
a combination of system factors can change this requirement.
