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 valves of the valve system are distinguished by coloured
identification on the function labels. Symbols corresponding to every
possible function of use are located on the discs for easy identification
and operation. The modular MANIFOLD system facilitates the addition
of optional extras on both pressure side and suction side. Furthermore
the suction manifold can be fitted with a return valve which ensures
better draining of the sprayer before cleaning. A function is activated by
turning the handle towards the desired function. The valves are:
A.
Agitation valve (optional equipment)
B.
Pressure valve
C.
Return valve
D.
Suction valve
E.
External filling device valve (optional equipment)
(D) Suction valve
This valve selects suction from main tank (for spraying) or rinsing tank.
Turn the handle so the indicator points towards the label of the required
function. If the handle is turned to vertical position (indicator not
pointing to a label), the valve is closed.
(B) Pressure valve
This valve selects where to direct pressurized liquid.
The active function is indicated by the indicator. Turn the handle so that the indicator points to the label of the required
function. If the handle is turned to a label-free position (unused function), the valve is closed.
(C) Return valve
With this valve you select whether return liquid should be directed back to the main tank or to the pump. Normally the liquid
is directed to the tank return. When the tank is nearly empty, the handle is turned so the liquid is directed to the suction side
of the pump in order to fully emptying the tank prior to cleaning.
(A) Agitation valve (optional)
With the Agitation valve you can select between agitation in the tank or tank cleaning with the rinsing nozzle.
Suction from main tank Suction from rinsing tank
Filling of main tank with
TurboFiller Spraying
Return to pump Return to main tank
