Fluoroplastic and fine ceramic are used in the liquid end parts. These materials enable strong acids, strong alkalines, and virtually all chemical solutions to be handled.

The exterior of the pumps is covered with ductile cast iron (FCD400). Ample pressure resistance has been provided in the rear casing through the adoption of a unique shape that prevents the concentration of stress, and a dual structure reinforced with an FRP cover. In addition, the spindle and magnet capsule, which are subject to the repetitive stress of rotational vibration, are made of fluororesin with special metal inserts. These are thus built to withstand sustained operation over an extended period under harsh service conditions.

The pumps have back pullout construction, enabling their internals to be inspected or their component parts to be replaced without disconnecting associated piping. Moreover, the simplified construction consisting of unit components makes maintenance and inspection easy.
