Diaphragm pump
Positive displacement pump made for long
life, easy service. Ideal for applications that
demand higher pressures, such as walking
spray booms, painting greens during the
winter months, and tree spraying.
• Pistons operate in oil bath for long life and
optimal lubrication.
• Mounting location allows for easy
servicing of diaphragm.
• Effectively handles paint and other tough
spray solutions.
• Excellent for providing plenty of
pressure for walking spray booms.
• Hydraulically driven.
Centrifugal pump
Pumping action is delivered by a rotating impeller.
Perfect for applications that demand higher fl ow
rates. Available in cast iron or stainless steel versions,
this proven, high-quality pump can be intermittently
run dry without failing its seal.

EXACT PRESSURE
Spraying is all about precision, which is why
throttling valves are standard equipment on
the SelectSpray Series. Whichever pump you
choose, they maintain correct system pressure
when individual booms are turned off and on.
EFFICIENT ROUTING
Short hose lengths and the combination
of throttling valve and strainer bypass lines
together makes for simpler plumbing.
EASY TROUBLESHOOTING
With only two primary valve-bank assemblies,
it’s easy to pinpoint the source of a potential
service issue. A pressure regulator assembly
includes jet agitator, self-cleaning line strainer,
and pressure regulator valve. The boom valve
assembly has three electric boom valves with
throttling valves and one manual valve for
hose reel or walking boom.
• Cast iron option is a good general purpose
sprayer pump.
• Stainless steel option can handle more
corrosive chemicals, like chelated iron.
• Powered by hydraulic motor.
• Standard bleed line helps maintain pump
priming by purging air from pump.
• LifeGuard™ silicon-carbide seals allow pump to
intermittently run dry without failing its seal.
