Installation and connection

For pumps in potentially explosive atmospheres (

ATEX

additional manual).

NOTE

Material damage due to distortion or passage of electrical
current in the bearing!

Do not make any structural modifications to the pump
assembly or pump casing.
Do not carry out any welding work on the pump assembly
or pump casing.

NOTE

Material damage caused by dirt!

Do not remove the transport seals until immediately before
installing the pump.
Do not remove any covers or transport and sealing covers
until immediately before connecting the pipes to the pump.

5.1

Preparing for installation

5.1.1

Check operating conditions

Ensure the required operating conditions are met:

Resistance of body and seal material to the medium
(

resistance lists).

Required ambient conditions

(

9.2.1 Ambient conditions, Page 32).

5.1.2

Preparing the installation site

Ensure the installation site meets the following conditions:

Pump is freely accessible from all sides

Sufficient space for the installation/removal of the pipes
and for maintenance and repair work, especially for the
removal and installation of the pump and the motor

Pump not exposed to external vibration (damage to
bearings)

No corrosive exposure

Frost protection

5.1.3

Prepare foundation and surface

Aids, tools, materials:

Steel shims

Spirit level

Installation options:

With concrete foundation

With steel foundation frames

Without foundation

1. Ensure the foundation and surface meet the following con-

ditions:

Level and horizontal

Clean (no oil, dust or other impurities)

Capable of bearing the weight of the pump assembly
and all operating forces

Stability of the pump ensured

With concrete foundation: Normal concrete of strength
class X0 in accordance with DIN EN 206

2. Clean pump sump carefully.
