Water and firefighting pumps, centrifugal end suction surface pumps, centrifugal double suction pumps (split case), centrifugal circulation inline pumps with dry rotors, vertical multistage pumps and boosters, firefighting pumps according nfpa20 with electric motors and diesel engines..Manufacturer
Applications: Designed for delivering treated water (feedwater) at the pumping temperature of up to 438K (165C) into the fossil-fueled stationary boilers with absolute steam pressure of maximum 13.7 MPa (140 kgf/cm2).
Capacity, Q = 100 m3/h, Head, H = 580 m, Speed of rotation, 2970 rpm, NPSHr = 4 m.
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.
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, if viewed from the drive side.
Applications: Designed for the supply of water to industrial plants and communities. They are used also for agricultural land irrigation and drainage.
Capacity, Q = 400 m3/h, Head, H = 105 m, Speed of rotation, 1470 rpm, NPSHr = 4.5 m
The pump units shall be rigidly anchored to the foundation, and piping shall be rigidly connected to the pumps.
The TsN type pumps are centrifugal, horizontal, spiral with horizontal split casing, with transfer channels, two- or four-stage, with single-entry impellers symmetrically arranged on the shaft according to type BB1 or BB3 API 610. The pump rotor is supported by grease-lubricated roller bearings. Shaft seals are gland packing. The pump casing is the main part of the pumps, which consists of the lower and upper half of the casing, connected together by studs.
Applications: Designed for handling condensate in the steam and water circuit systems of the thermal power stations that burn organic fuel. May be also used to transfer water in heating plants and water supply systems.
Performance of the Pump:
Capacity, Q = 80 m3/h, Head, H = 155 m, Speed of rotation, 2940 rpm, NPSHr = 1.6 m
The pump as a component of the pump unit is an electrically driven horizontal multistage ring-section centrifugal pump between bearings, with single flow impeller arrangement.
The suction casing, delivery casing and stage casings are bolted together with tie bolts to form a pump casing. The suction nozzle integrally cast with the suction casing is located horizontally at side (radially to the pump centerline). The discharge nozzle integrally cast with the delivery casing is oriented vertically upwards. The pump casing is supported at the bottom with feet integrally cast with the suction and delivery casings. The pumping unit alignment is maintained during its operation due to dowelling the delivery casing to the baseplate, whilst the other end of the pump can slide axially thus allowing for free expansion of static components.
D 2500-62-2-S UKhL4 ( 2500-62-2- 4) make Between-Bearings Double Flow Axially Split Pumps
Pump parameters:
Capacity, Q = 2500 m3/hr, Head, H = 62 m, Speed of rotation 980 RPM, NPSHr = 6 m/
Applications: Designed for the supply of water to industrial plants and communities. They are used also for agricultural land irrigation and drainage.
Design:
The pump units shall be rigidly anchored to the foundation, and piping shall be rigidly connected to the pumps.
The pumps are electrically driven horizontal, foot-mounted, single-stage, axially split volute casing centrifugal pumps with a double entry radial impeller. The pump casing is a locating part of the pumps, which incorporates a lower and an upper casing halves bolted together by means of studs.
Pump shaft sealing is by means of packed glands.
Sense of rotation of shaft in all the pumps is counterclockwise, if viewed from the drive side.
Upon the Customer request, the pumps may be supplied with a rotor for reverse rotation.
