7.Maintenance

2021/11

Assembly

Install the discharge valve (96A) on the pump by means of seal (91E) and clamp (91D).

Attach the discharge tube (98) to the elbow clamp from mixer

’s entrance

by means of seal (91C) and clamp

(91A).

Finally, fasten the discharge tube (98) to the discharge valve (96A) using seal (91E) and clamp (91D).

Position the venturi tube (102) on the tube clamp (38A) but do not tighten down. Then, join the venturi tube

(102) to the pump by means of seal (91B) and clamp (91). Subsequently, finish fastening the venturi tube to
the frame by strongly tightening down the tube clamp (38A).

Join the butterfly valve (96) to the venturi tube (102) by means of seal (91B) and clamp (91).

To assembly the hopper, put the flat washer (18) on the frame (38) by aligning the seal drill holes with those

on the frame.

Place the hopper (101) on the frame (38) aligning the threaded studs used for fixing the hopper (101) with

the drill holes on the frame (38) and the seal (18).

Join the hopper to the butterfly valve (96) by means of seal (91B) and clamp (91).

Fasten the hopper (101) to the frame (38) using washers (53) and blind nuts (54).

7.4.2.

Pump and/or mixer

Proceed to maintenance, disassembly and assembly of the pump and/or mixer according the specifications from own
instruction of each component.

ATTENTION! When installing the new seal on the pump or mixer, use soapy water when

fitting the different parts and gaskets to allow them to slide better; apply to the
stationary as well as the rotating parts.
