APPLICATION

nnnn

Volute casing pumps of the ZLK range (meeting DIN 24255 / EN

nnnn

733 and ISO 9908) are used when clear or turbid liquids free from

nnnn

solid particles are to be pumped. Application areas for pumps in

nnnn

this range include:

nnnn

Automobile, mechanical and general engineering industries

nnnn

Food and beverage industry

nnnn

Pharmaceutical industry

nnnn

Paint industry

nnnn

Plastics and rubber industry

nnnn

Iron and non-ferrous metal industry

nnnn

Paper and pulp industry

nnnn

Textile industry

nnnn

Building and construction industry

nnnn

Heating and air conditioning

nnnn

Drainage

nnnn

Water supply

nnnn

Irrigation

nnnn

DESIGN

nnnn

Single-stage volute casing pumps with connections and nominal

nnnn

performances according to DIN 24255 / EN 733, plus 6 additional

nnnn

sizes.

nnnn

The design of the pump allows the complete drive unit to be

nnnn

withdraw from the casing without disturbing the attached pipe work.

nnnn

The close coupled design, also, allows dismantling or replacing the

nnnn

motor without disturbing the pump.

nnnn

There is no common shaft for pump and motor, standard motors

nnnn

can be used.

nnnn

The set is a space saving easy to install pump unit.

nnnn

The range covers 34 sizes.

nnnn

1) from 100160 to 200250 10 bar

nnnn

Shaft sealing:

nnnn

The shaft is sealed by means of a single mechanical seal, flushed

nnnn

from internal source.

nnnn
