Send back to the manufacturer the pump, the pump, the pressure pump, the complete evacuation of the pump, the disconnection of the electrical connection, and ensure that the motor will not reconnect the pump, the cooling of the pump, the removal of the coupling protection with the spacer: the removal of the spacer, the shutdown of the auxiliary operating system, the pressure gauge pipe, the press and the bracket that are free of pressure and have been evacuated and removed, only mail the pump or parts with the authentic and complete proof. If necessary, ask the manufacturer for the safety certificate (→ 9.4 Safety certificate, 41 pages)

Prepare to disassemble the pump No pressure pump Completely empty it, clean and disinfect it Disconnect the electrical connection, and ensure that the motor will not reconnect the pump has cooled down Remove the coupling protection

Coupling with spacer: remove the spacer and shut down the auxiliary operating system. There is no pressure and the pressure gauge pipe has been evacuated. When using the coupling with spacer, the motor can be installed on the bottom plate.

Attention during disassembly:

– Before disassembly, mark the installation position and orientation of all components accurately.

– Remove the components in the center without tilting them.

– Remove the pump (→ sectional view)

install

Re install the parts concentrically according to the marks without any inclination.

warning

Danger of injury from heavy components!

Pay attention to the weight of components, and use the corresponding lifting device to lift and transport heavy components.

Place components safely to prevent tilting and rolling.

warning

Danger of injury during installation! Carefully install parts with springs (such as end seals, pretensioned bearings, valves, etc.), as spring tension parts may be ejected.

Pay attention to the manufacturer's instructions (e.g. for motors, couplings, end seals, drainage equipment, cardan shafts, drives, belt drives, etc.).

instructions

Improper parts will cause property damage!

If necessary, replace the missing or damaged bolts with bolts of the same strength (→ 9.2.4 tightening torque, page 37). Seals can only be replaced with seals of the same material.

1. Attention during installation:

– Replace worn parts with original accessories.

– Replace the seal and install it freely.

– Observe the specified torque (→ 9.2.4 Tightening torque, page 37)

2. Clean all parts (→ 9.2.6 Cleaner, 37 pages). At the same time, remove the possible good marks.

3. Install the pump (→ sectional view).

4. Install the pump in the equipment (→ 5 Installation and connection, page 16)

7.5 Ordering spare parts

In order to be easily replaced in case of damage, it is recommended to reserve a complete insert assembly or a spare pump. It is recommended to reserve spare parts for continuous operation for 2 years according to the guidelines of DIN 24296. (→ 9.3 According to DIN 24296 standard, spare parts can be used for two consecutive years (40 pages)

Keep the following information for spare parts ordering (→ model nameplate):

– Abbreviated name of the pump

– Pump code

– Year of manufacture

– Component code

– Name

– Number of pieces
