FLANGED PUMP CONNECTOR MANUFACTURERS & SUPPLIERS Pump connectors are normally provided for vibration and noise isolation between the piping and the vibration equipment. A standard pump connector consists of a stainless steel braided hose with fitting. These fittings come with either a flange type or threaded type pipe end. Of the two, threaded connections cost less than flange connections, as flanges have multiple parts & configurations. Designed for mechanical equipment, pump connectors are manufactured from authentic stainless steel. Pump connectors of longer lengths can be made to accommodate additional lateral deflection and excessive vibration based on specific customer requirements. In most cases, stainless steel pump connectors are used to replace single arch rubber connectors.
