Designed for delivering treated water (feedwater) at the pumping temperature of up to 438К (165oС) into the fossil-fueled stationary boilers with absolute steam pressure of maximum 13.7 MPa (140 kgf/cm2).

Description:

APE series pump units consist of a centrifugal pump and an induction motor, which are mounted on a common fabricated base plate. In case of АПЭ 150-63 and АПЭ 250 models the pump and motor are mounted on separate base plates. The pump and motor shafts are connected by means of a rubber-bushed (pin-and-bushing) flexible coupling enclosed with a coupling guard.

The APE 270-150 and APE 250 pump unit models are equipped with a gear-type coupling and is furnished with a pressure lubrication installation to provide their coupling and bearings with lube oil.

The pump units shall be rigidly anchored to the foundation, and piping shall be also rigidly connected to the pumps.

The pumps are motor-driven horizontal, centreline-supported, between-bearings multistage ring-section centrifugal pumps with single flow impeller arrangement.

The pump casing comprises a suction casing, a delivery casing and a set of stage casings, which are concentrically aligned with respect to each other on rabbeted fits and are bolted together with tie bolts. Diffusers are built in the stage casings and delivery casing.

The suction and delivery casings have flanged suction and discharge pump nozzles respectively, which are oriented vertically to the top.

The rotor axial thrust is automatically balanced with a balance disc. In order to ensure a normal functioning of the balancing device, its chamber is to be communicated with the suction pipeline. A bearing end cover, fitted in the non-drive side bearing housing, has a shaft position indicator for sight control of the wear of balancing device surfaces and for restraining rotor axial displacements towards the delivery side.

The pump rotor is carried by the plain bearings with ring lubrication (with forced lubrication from a pressure lubrication installation for the pump PE 270-150).

The design of pump shaft seal chambers provides both for housing mechanical seals and for packing the stuffing boxes, which are to fed with cooling liquid.
