Liquid system

Pump

Diaphragm pump with 3 diaphragms, model 1303 or diaphragm pump with 6 diaphragms, model 363 or 463. Standard =
540 r.p.m. (6 splines shaft). Optional = 1000 r.p.m. (21 splines shaft). The design of the diaphragm pump is simple, with easily
accessible diaphragms and valves which ensures liquid does not contact the vital parts of the pump.

Valves and symbols

The possible functions of valves are distinguished by coloured identification on the function labels. The modular valve
system facilitates the addition of optional extras on both pressure side and suction side. A function is activated by turning
the handle towards the desired function.
μ
ATTENTION! Only the functions used should be open - always close remaining valves.
μ
ATTENTION! If a valve is too tight to operate - or to loose (= liquid leakage) - the valve needs to be serviced. Please see
the section 'Maintenance' for further information.
Pressure SmartValve (Green symbols)
This valve is to select 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 handle is turned
to a position without label (unused function) then the valve is closed.
Main tank
IInternal tank cleaning
(Rinsing nozzles)
(optional)
Suction valve (Blue symbols)
This valve is to select suction from main tank or from the rinsing tank.
The handle is turned so the label for required function is directed to the
indicator. If handle is turned to vertical position (indicator not pointing
at a label) then the valve is closed.
Main tank
Agitation valve (White symbols)
With the adjustable Agitation valve it is possible to combine spraying
with a high volume rate at high pressure with agitation at the same time.
This is controlled continously by the valve: The valve is marked with an
arrow on the disc that indicates the amount of liquid that passes
through the valve.
• Handle is turned to a position near the tip of the arrow: Only a
small amount of liquid is allowed to pass the valve resulting to a
lesser extent of agitation.
