The MHH Series are similar to EVR’s series of pump connectors in that engineering and materials can be matched to any situation. Available in diameters ranging from 1 to 24 inches and in lengths up to 50 feet. The MMH Series are available with full face flanges and backing rings, built-in steel nipples or a beaded-end design which provides a rotating floating metallic flange that gives perfect bolt alignment to both new and old installations, without torsion.
