SPECK Pump ASK Series

Side channel pumps with NPSH suction stage in modular design with mechanical seal or magnetic coupling (Self Priming, Delivering Gas)


Pumps of the ASK and ASK-MK series are designed for the delivery and re-circulation of liquids at unfavourable suction-side conditions and liquids close boiling point.

They are suitable for liquids without abrasive contaminatuions and without solid content.

For example :
– Boiler Feed Water
– Condensates
– Distillates
– Liquid Gas
– Coolants
– Solvents

Main Applications

The pumps are mainly used in the following sectors :
– Basic process engineering
– Chemical industry
– Food, beverages and tobacco industry
– Instrument engineering
– Shipping
