Self-priming magnetic drive pumps that are resistant to dry running. The SMD series is horizontal type self-priming magnetic drive pumps made of reinforced plastic. Since these pumps are of the gas-liquid separation type and do not require the use of a chamber or self-priming valve, they provide high self-priming speeds and perform self-repriming efficiently. Their pumping sections incorporate our patented pinpoint contact system, which has already gained an outstanding reputation through its use in the MDH series pumps. These pumps offer significantly improved durability during dry running operations...
