BADU®21-80 SP
Self-priming circulation pumps
 |
Our range of pumps for installation of the types 21-80/32 SP to 21-80/34 SP are single stage spiral casing centrifugal pumps of high efficiency thus energy-saving. They are compact and reliable. All parts in touch with the pumped liquid are made of anticorrosive synthetic material or of stainless and acid-resisting steel. Field of application includes pool and industrial filtration units, counter swim units, air conditioning units, pool attractions, cleaning units and many other applications with flow rate up to 90m3/h.
Priming-times completely depend on the installation. The suction line should be short. A pressure line of 0,35m above shaft level
allows a suction head of 1m in about 1 minute. For larger suction heads a check valve should be provided in the suction line.
Consequently, a 0,5m vertical pressure line allows suction heads up to 4m – depending on the pump size.
