Big on power yet short on energy consumption, the SP Series is one of the most versatile and economical centrifugal pumps on the market.
The exclusive SP Series combines deep-lift capabilities (up to 7.6 metres) lightning fast priming (5.5 metres in 90 seconds) with the advantages of magnetic drive technology, ensuring ease of operation with no seal replacement, no leaks and the capability to run-dry without damage.
What's more, its innovative design and corrosion resistant materials make the SP Series ideal for handling even the most difficult applications

- When run dry protection is need
Thermoplastic Priming Chamber
Functions as a fluid reservoir and features molded-in 'gooseneck' suction passage eliminating the need for internal check valves, integral fill and drain ports are standard. Available in GF-PP or CF-PVDF for optimal corrosion resistance
O Ring
Creates airtight seal between the inner volute and the 'gooseneck' suction passage. Helps the pump maintain the vacuum required for proper priming
Multiple Connections
NPT or BSP threads, raised face adjustable flanges or union
Separator Plate
Acts as a barrier between the low velocity fluid reservoir and the high velocity area in the rear of the priming chamber. Openings allow liquid to flow to the impeller and discharge the air/liquid mixture created during priming back into the fluid reservoir
Inner Volute
Houses the rotating impeller. Special design allows air to be efficiently removed from the suction passages for fast priming
Multiple Impeller Diameters
Allows hydraulic requirements to be precisely met. Two piece impeller design allows impeller to be changed without having to replace inner drive
Run Dry System
The SP can run dry without damage when equipped with a chemical grade carbon busing in optimum operating conditions. This helps protect the pump from operator errors and system upsets
Easy Set Outer Drive
Measurement-free outer drive ensures optimum magnet alignment and easy motor installation
