Installation 4
4.1 Direction of Rotation
The direction of rotation is stated in the data sheet as well as on the pump type plate and must be
absolutely kept for the avoidance of damage of the shaft seal (dependent on direction of rotation
mechanical seals). The direction of delivery (flow direction) will be determined by means of the
direction of pump rotation.
4.2 Fastening of horizontal pumps
The pump is mounted by means of the mounting lugs on the base plate or the mounting holes
provided on bearing chair (KL20);
the mounting lugs on the base plate or the mounting holes provided on bearing chair and discharge
nozzle. (KL30 - KL 80). The pump has to be mounted on firm and level ground, e.g.

sufficiently dimensioned level concrete base plate;

a level and warp resistant steel construction.
The foundation must be designed so that it can take the weight of the pump aggregate on the entire
surface. It must fully absorb the load exerted on the foundations and ensure the stability of the pump
aggregate.
The diameter of holes at bearing chair and discharge nozzle support or the straight plates of the
base plate describe the bolt diameter respectively the diameter of the anchor dowels.
4.3 Fastening of vertical pumps
As a rule vertical pumps or pumps are mounted vertically get fixed on a hanging bracket or special
devices. (E.g. fixing flanges

see Data Sheet).
For all KLT pumps from series KLT 50 onwards, the fastening must be made as described in the
following:

by suspending on the hanging bracket (fixed setting) or

using the fastening on the lower bracket on the immersion tube and fixation via the bearing block
of the pump.

using the mounting flange, with which the pump is firmly attachment via this flange, or

using a 'tripod' which stands upright and is secured against slipping and using the bearing block
of the pump.
For immersion pumps (with a mounting flange and a homogeniser) whose discharge height is over 5
metres, an additional collection basket must be installed on the tank floor that securely prevents the
oscillation of the pump.
Possible damage

With sizes KL50T, KL65T, KL80T and KL100T, fastening via the bearing block of the pump
alone may result in a fracture of the bearing block housing.
