Construction

The construction of process pump type AY is divided into seven kinds:single-suction.Double-stage and single-suctionetc.

The pump casing is split radially and installed horizontally,centerline mounted.The suction and discharge nozzle flanges are cast together on the pump casing and vertical upwards. The stuffing boxes and pump cover are cast together which can be installed with soft packing seal and mechanical seals. The water-cooled chamber jacket,which can be selected,is installed outside of shaft sealing chamber.

The impeller is cast integrally and balanced statically.The axial thrust of pump is balanced mainly by balancing disc,balancing drum and thrust bearing for multi-stage pump.

A journal ball bearing and thrust ball bbearing arranged back-to-back are installed on the bearing housing.And sliding bearing is mounted for multi-stage pump type 65AY to 150AY.The bearing housing of single-stage or two-stage pump is furnished with cooling fins that can be cooled by air and by fan. The bearing housing also can be cooled by water.

A flexible membrane spacer coupling assembly is installed on the pump to disassemble impeller,shaft,bearing,shaft sealing,etc,without disturbing suction and discharge pipeline.
