APPLICATION
Volute casing pumps of the ZLK range (meeting DIN 24255 / EN
733 and ISO 9908) are used when clear or turbid liquids free from
solid particles are to be pumped. Application areas for pumps in
this range include:
Automobile, mechanical and general engineering industries
Food and beverage industry
Pharmaceutical industry
Paint industry
Plastics and rubber industry
Iron and non-ferrous metal industry
Paper and pulp industry
Textile industry
Building and construction industry
Heating and air conditioning
Drainage
Water supply
Irrigation
DESIGN
Single-stage volute casing pumps with connections and nominal
performances according to DIN 24255 / EN 733, plus 6 additional
sizes.
The design of the pump allows the complete drive unit to be
withdraw from the casing without disturbing the attached pipe work.
The close coupled design, also, allows dismantling or replacing the
motor without disturbing the pump.
There is no common shaft for pump and motor, standard motors
can be used.
The set is a space saving easy to install pump unit.
The range covers 34 sizes.
1) from 100160 to 200250 10 bar
CONSTRUCTION
Casing pressure:
Material 4B: max. 16 bar from -40 °C to 120 °C
Material 0B, 0C, 0E: max. 16/101) bar form -20 °C to 120 °C
Max. casing pressure = inlet pressure plus delivery head at zero
flow
Please note: The relevant technical regulations and safety rules
must be observed.
Flanges location:
Axial suction flange, discharge flange radially upwards.
Flanges:
Material 4B: Correspond to DIN EN 1092-1/PN16.
Material 0B, 0C, 0E : Correspond to DIN EN 1092-2/PN 16/101).
Flanges drilled according to ANSI 150 can be supplied.
