Liquid System; Pump; Valves And Symbols - Hardi NAVIGATOR DELTA FORCE Instruction Book

Liquid System

Pump

Diaphragm pump with 6 diaphragms, model 363 or 364 or 464.
Standard = 540 rpm (6 splines shaft). Optional = 1000 rpm (21 splines
shaft). The design of the diaphragm pump is simple, with easily
accessible diaphragms and valves, which ensure that liquid does not
contact the vital parts of the pump.
Pump model 363 is shown on the picture.

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
"Adjustment of 3-Way Valve" on page 133 for further information.
