Solenoid pumps as close-coupled pumps are available in many sizes and designs. From very small mini sizes up to roughly 100 m³/h. An enquiry is always worthwhile, even if a lot of data is missing here. Below are some sample photos. The following versions are available, depending on size and operating conditions:
- normally aspirating
- self priming
- partly up to 3-stage for higher pressures
- partly according to ATEX
- made of PP, PVDF plastic and stainless steel
- mini volume flow to very high pressures as a drive vane pump, up to 200 m and up to 1200 l/h, as magnetic seal-less or with mechanical seal
