APPLICATION
Volute casing pumps of the ZLN 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
Plastic 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
A range of materials is available to meet the specific needs of
customers. For applications not covered by this pump range we offer
the ISOchem range.
DESIGN
Horizontal, single-stage volute casing pumps with connections and
main dimensions to DIN 24255 / EN 733, plus 19 additional sizes.
The design of the pump allows the complete drive unit to be
withdrawn from the casing without disturbing the attached pipe work.
If a spacer type coupling is used, it is also unnecessary to disconnect
the motor.
The range covers 50 sizes with only 5 different bearing brackets.
CONSTRUCTION
Casing pressure:
Material 4B: max 16 bar from - 40 °C to +120 °C
max 14 bar from 120ºC up to +170 °C
Material 0B, 0C, 0E: max 16/101)/142) bar from - 20 °C to +120 °C
max 14/91)/82) bar from 120 ºC up to +170 °C
Max. casing pressure= inlet pressure + 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 design 4B: Complies with DIN 2543 PN 16
Material design 0B, 0C, 0E: DIN 2533 PN 16 / 2532 PN 103)
Flanges drilled according to ANSI 150 can be supplied.
