PRINCIPLE OF
OPERATION
The Warren Rupp Electro-
Pneumatic Speed Control System is
comprised of three components that
operate with most diaphragm pumps
to optimize operational variable fl ow
rate demands.
The fi rst component is an
electronically operated proportional
pilot valve that utilizes patented tech-
nology to provide extremely accurate
pneumatic control in a NEMA 4X
rated container. (See Figure 1.)
The second component is
a diaphragm, air-piloted pressure
regulator that offers higher fl ow rates
that translate into faster responses.
(See Figure 2.)
CAUTION!
Always disconnect
power before working
on units.
