Where particularly aggressive liquids are encountered, the SP borehole pumps are available in extra high grade stainless steel DIN W.-Nr. 1.4401 (AISI 316), or, for severe conditions, DIN W.-Nr. 1.4539 (AISI 904 L).
Please note: The range of SP Single Phase pumps must be installed with an SA-SP M3 control box to protect the warranty.
