through the lengths of hose. For example, a 3 GPM system will
require (lose) 50 PSI per 50 . of 3/8” ID hose. A pump with
only 60-70 PSI may not provide the desired performance at the
end of the hose. See reference charts to assist in system design.
MISTING
It is crical to size the pump correctly in a misng applicaon. If
insucient ow is chosen, then proper atomizaon and droplet
size will not result. If excessive ow is chosen, then unnecessary
wear and wasted energy will occur in this very demanding
applicaon. Refer to the Nozzle Performance Chart for your
chosen nozzles to determine the required total ow at desired
pressure. For example, if 1000 PSI is desired from 20 pieces of
‘08 misng nozzles, then a minimum ow rate of 0.4 GPM is
required. Allowances need to be made for losses from tubing
lengths and ngs, too. It would be unwise in this situaon to
choose a 0.75 or 1.0 GPM pumping system.
Another consideraon for misng concerns the roung of the
bypass uid. DO NOT return bypass uid from regulang valve
directly back to inlet of pump. The returned uid will contain
large amounts of air bubbles that will cause cavitaon and
damage in the pump head. Also, the small amount of returned
uid can heat up rapidly and lead to further cavitaon and
component damage. It is recommended to route bypass back
to inlet of lter to allow air bubbles to dissolve and water to
cool prior to entering pump.
The pumps are shipped assembled to a custom-made
motor based upon your specicaons. It is not necessary to
order a motor separately. Communicate your specicaon
requirements and the supplier will assist with pump opons.
Please use the following charts as a guide to understand the
basic system requirements.
NOTE: Nozzle sizes in the performance chart are addive. For
example, 2 pieces of ’02 nozzle equals the performance of 1
piece of ’04.
Nozzles create restricon (pressure) in the system. If unsure
of the nozzle size needed for desired performance, refer to
Nozzle Performance Chart. If you are sure of your nozzle
size, but unsure of which pump set to choose, then use the
Nozzle Performance Chart along with the Horsepower Chart to
determine your required pump specicaon.
An example of how to use these charts together: when you
have 2 pieces of an ’02 nozzle and you want 500 PSI, the Nozzle
Chart will tell you that 2 pieces of an ’02 nozzle has a ow equal
to 1 piece of an ’04 nozzle. At 500 PSI, an ’04 nozzle has a ow
of 1.4 GPM. The performance specicaon is 1.4 GPM at 500
PSI.
The Horsepower Chart indicates that 1.4 GPM at 500 PSI
requires .408 HP. You will need to select a pump set that can
perform at this level. Refer to page 6.
