The heart of your sprayer is the diaphragm pump. The design is simple,
resulting in low maintenance requirements and guaranteed pump life.
The bearings and crankshaft are grease lubricated and are therefore
protected from spray solution if any diaphragm fails in service. A drain
hole is located in the base of the crank case to facilitate the draining of
any foreign matter. The pump is self-priming and can be run dry without
damage.
The EC-3 electric control unit consists of: Electrically operated master
on/off valve, electrically operated boom distribution valves, manual
pressure adjustment valve, 2-1/2" pressure gauge, and adjustable
pressure agitation.
The ET-2/ET-3 manual control unit consists of: Manual pressure
adjustment valve, boom distribution valves, 2-1/2" pressure gauge, and
adjustable pressure agitation.
