SIHI SuperNova Pump ZLN

SIHI SuperNova Pump ZLN are horizontal, single-stage volute casing pumps with connections and main dimensions to DIN 24255 / EN 733, plus 19 additional sizes. The design of the ZLN pump allows the complete drive unit to be withdrawn from the casing without disturbing the attached pipe work. A spacer type coupling is standard making re-alignment unnecessary. The range covers 50 sizes with only 5 different bearing brackets. Compared to its competitors this pump range has larger shafts, giving longer seal and bearing life. Also, see ZLI and ZLK close coupled pumps.

Volute casing pumps of the SIHI SuperNova Pump 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.

A range of materials is available to meet the specific needs of customers. For applications not covered by this pump range, we will be able to offer an alternative Flowserve pump.
