A Wet End PUMP KIT includes everything needed to assemble a close coupled end suction centrifugal pump except the motor itself. Standard construction is all close grain cast iron with bronze shaft sleeves and volute wear rings where applicable. Bronze fitted kits (identified with a BF suffix) are constructed the same as standard units except they have bronze impeller. On all-bronze kits (-AB suffix), all wetted surfaces are bronze castings. Other seals and sleeves are available for special conditions. Consult factory for additional information.
