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) Water quality according to VdTÜV 1466; additional requirement:O2 (oxygene) < 0,02 mg/l.
2) from 100160 to 200250 10 bar
CONSTRUCTION
Casing pressure:
Material 4B: max. 16 bar from -40 °C to 120 °C
max. 14 bar from 120 °C to 140 °C
Material 0B, 0C, 0E: max. 16/102) bar form -20 °C to 120 °C
max. 14/92) bar form 120 °C to 140 °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 16/102).
Flanges drilled according to ANSI 150 can be supplied.
Hydraulic:
Frist Hydraulic: Design code A
Second Hydraulic: Design code B
Bearing:
Bearing bracket equipped with one ball bearing lifetime greased according to DIN 625.
Volute casing with feet, n = 1450 rpm. code: 3
Volute casing without feet, n = 2900 rpm. code: 4
Shaft sealing:
The shaft is sealed by means of a single mechanical seal, flushed from internal source.
Code B27: Unbalanced bellows mechanical seal, seal face materials WC/carbon, elastomer EPDM
Code BH3: Unbalanced bellows mechanical seal, seal face materials SiC/carbon, elastomer EPDM
Code BHS: Unbalanced bellows mechanical seal, seal face materials SiC/SiC, elastomer FPM (Viton)
Code BHJ: Unbalanced bellows mechanical seal, seal face materials SiC/carbon, elastomer FPM (Viton)
