DISCHARGE CONDITIONS

Open all valves in system prior to operaon to avoid excessive

load on motor and system from a pressure spike. Follow the

instrucons of proper system design. Refer to supplier if

assistance is needed.

PRESSURE REGULATION

Verify pressure regulaon devices are operang correctly.

NOZZLES

Nozzles create pressure in most systems and they become

larger with use. Larger nozzles decrease system pressure. Verify

the quality of nozzles prior to operaon.

OPERATION

GENERAL OPERATING INFORMATION

Pressure is oen created by forcing a volume of uid (ow)

through a specic size hole (nozzle). Addionally, pressure can

be created by pumping into a non-expanding chamber. Pressure

is measured and stated in PSI – pounds per square inch.

Flow is created based upon the pump displacement and speed

(RPM) of the motor. Pump plunger size aects ow based upon

the same RPM. The faster the motor speed, the greater the

ow. Flow is measured and stated in GPM – gallons per minute.

The pump, driven by a motor or engine, draws uid through a

set of valves into the pumping chamber and the uid is then

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 sucon and discharge acons.

Once the uid has exited the pump it must be controlled

unl 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 regulang valve. The pumps are

posive displacement pumps providing a specic amount of

uid constantly while operang. This volume of uid must

be directed out thru a nozzle or back to a tank because it

cannot be stopped completely without creang excessively

high pressure and risk of damage to pump, components,

property and person. It is recommended a safety device such

as a regulang valve be installed directly on pump head as

protecon in case of a failure of another component. Pressure

switches can be used to automate pump operaon, but they

must have a pressure regulang device installed as a safety

device.

Fluid can enter a pump either from a ltered tank or

pressurized uid line.

It is common to use a tank with pumps that are mounted above

the pump. Filtraon is important to maintain proper funcon

of the pump and system. The extent of ltraon may be greater

based upon some uses such as misng with ultra-ne nozzles.

Inadequate inlet condions can cause serious malfuncons in

the best designed pump. Surprisingly, the simplest of things

can cause the most severe problems or go unnoced 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.

delivered by the pump to assure proper performance.

• Open inlet shut-o 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 ows. Condions vary with

regulang/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 mes the GPM

(however, a combinaon of system factors can change this

requirement).
