Applications: designed for delivering treated water (feedwater) at the pumping temperature of up to 438К ted, nsure 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. Sense of rotation of shaft in all the pumps is counterclockwise (clockwise in case of pe 270-150), if viewed from the drive side. Pump designation: first number indicates the capacity, m3/h; the second number indicates the head, kgf/cm2.
