7.3.2 Dismounting
Pump depressurized
Pump completely empty, flush ed and decontaminated
Electrical connections disconnected and motor secured
against being switched on again
Pump cooled down
Auxiliary systems s hut down, depressurized and emptied
Manometer lines, man ometer and holdings dismounted
WARNING
Risk of injury during disassembly!
Secure the pressure-side gate valve against accidental
opening.
Depressurize the blocking pressure system, if available.
Wear protective gloves as components can b ecome very
sharp through wear or d amage.
Remove spring-loaded components c areful ly (e.g.
mechanical seal, tensioned bearing, valves etc.), as com-
ponents can be ejected by the spring tension.
Observe the manufacturer's specifications (e.g. for the
motor, coupling, m echanica l seal, blocking pressure sys-
tem, cardan shaft, drives, belt drive etc.).
1. Observe the following during removal:
– Mark the precise orientatio n and posi tion of all compo-
nents before dismounting them.
– Dismount components concentrically without canting.
2. Dismount the pump (→ sectional and exploded drawing).
7.3.3 I ns talling
Install the components concentricall y, without canting, in
accordance with the markings made.
NOTE
Material damage due to unsuitable components!
Always replace lo st or damaged screws with screws o f the
same strength (→ 9.2.3 Tightening torques, Page 31).
Only replace s eals with seals of the same material.
1. Observe the following during installation:
– Replace wo rn parts with genu ine spare parts.
– Replace seals, inserting them in such a way that they
are unable to rotate.
– Maintain the prescribed tightening torques
(→ 9.2.3 Tightening torques, Page 31).
2. Clean all parts (→ 9.2.6 C leaning agents, Page 32). Do
not remove any markings which have been applied.
3. Replace the antifriction bearings.
4. Install the pump (→ 9.1 Sectional drawings, Page 28).
