Typical Installation

The installations shown in Fig. 2 are only a guide to help
select and install a pump; they are not actual system
designs.

Typical installation includes (not supplied by Graymills):

D

For solenoid operation: a four-way, 5-port, 3-position
solenoid valve with 1/4-in. ports, or two 3–position
3–way valves. Mac series 44 (4–way), or series 35
(3–way). Either way, air pressure should be released if
not cycling.

D

PLC or timer.  Consult your local industrial controls
distributor.

For solenoid operation, the pump must exhaust through
the solenoid.  Failure to exhaust through solenoid could
cause the diaphragms to fail.
