Liquid System
Pump
Diaphragm pump with easily accessible valves and diaphragms. Model
364 or 464 with 6 diaphragms.
Standard = 540 r.p.m. (6 splines). Optional = 1000 r.p.m. (20 or 21 splines).
The design of the diaphragm pump is simple, with easily accessible
diaphragms and valves that ensure liquid does not contact the vital parts
of the pump.
Pump model 464 is shown in the picture.
Valves and Symbols
The possible functions of valves are indicated by colored discs on the function labels. The modular valve system allows for
the addition of optional extras on both the pressure and suction side. A function is activated by turning the handle towards
the desired function.
˜
ATTENTION! Only the functions used should be open - always close remaining valves.
˜
ATTENTION! If a valve is too tight or too loose to operate (= liquid leakage), then the valve needs to be serviced. Please
see “Adjustment of 3-Way Valve” on page 80 for further information.
Pressure SmartValve (Green Symbols)
This valve selects which function the pressurized liquid from the pump
will be routed to.
The active function is indicated by the indicator. The handle is turned so
the indicator points to the label for required function. If the handle is
turned to a position without label (unused function), the valve is closed.
