Applications & Industries• For all applications where a self-priming pump is required. The pump is adapted for conveying clean, contaminat-ed liquids or dissolved gases (or not), which do not contain abrasive substances .• Supplying heaters, construction of installations, chemical and petrochemical industries, machine building, ship building, agriculture, and residential solution for irrigation/watering and drainage.

Features• The pumps come with oval counter flanges with threaded holes in 1″, 1¼” and 1½” • Maximum total head between 110 and 160 mCI since the pump is limited to 16 bar and 7.5 m 3 /h.

Applications & Industries • For all applications where a self-priming pump is required.

Features • Pumps come with one block (ZS_SFH…W) or two blocks (ZS_SFH…WW) • Maximum total head between 140 and 240 mCI since the pump is limited to 25 bar and 20 m 3 /h.

Applications • The pumps in this series are made of standard, interchangeable hydraulic parts. They have a consistent perfor-mance level and comply with DIN 24254, which makes them interchangeable with other manufacturers’ pumps. • Combined with the ZS_SFH pumps, they can be used for difficult chemical and engineering applications.

Features • Range of pumps complying with DIN 24254 or DIN/EN 734 • Maximum total head between 220 and 350 mCI since the pump is limited to 40 bar and 36 m 3 /h
