Working diaphragm

Fig. 43 (Disassembly of working diaphragm)



Screw working diaphragm onto connecting rod



Set stroke length to 50 %



Put pump body onto base ring. Tighten fixing screws
crosswise with correct torque (see Chapter. 8.1 / Ta-
ble.09).



When mounting the pump body please note:

CAUTION !

Pressure valve above; suction valve below !

(Consider the direction of the arrows on the valves, described
in Chapter 7.2.5)



Note direction of arrow on pump body



Fix suction and pressure line



Reset original stroke length



Apply voltage



The solenoid diaphragm pump is ready for operation

Fault analysis and corrective action

sera

- products are sophisticated technical products which are

only shipped after having been thoroughly tested and checked
at our factory.
Should there be any faults, these can be detected and rectified
easily and quickly if the steps in Table 14 are carried out.
