LDTN Vertical Multistage Barrel Condensate Pump

Product details

LDTN pump is a vertical multi-stage barrel structure, with the suction and discharge ports located on the discharge seat. Suction and discharge ports can be adjusted at multiple angles such as 180 degrees and 90 degrees angle, and the impeller is closed. Pump inlet diameter is 80-400mm, the flow rate is 7-702m3/h, the head is 35-232m, the power is 3-630KW, and the voltage is 380V/6000V. LDTN type condensate pump is suitable for transporting condensate water in the condenser of thermal (nuclear) power plants, and can also be used in chemical processes with restricted installation surfaces such as NPSH to transport water with physical and chemical properties similar to water, with a water temperature not exceeding 180 degrees. 200LDTN-125*5. 200: suction diameter 200mm. L: vertical. D: multistage. T: barrel type. N: Condensate pump. 125: Discharge diameter 125mm. 5: Pump stage. Transporting clean or slightly contaminated chemically neutral or corrosive liquids in refinery, petrochemical plant, power plant, pipeline pressurization, offshore oil extraction platform. Vertical barrel pump is multi-stage and radially split. The type of impeller is a single suction radial type, equipped with a single-stage shell, and the first stage impeller is generally a suction type impeller. The axial force is borne by the centripetal thrust ball bearing. In the case of a large pressure difference, the axial force is balanced by the balance drum device. The shell only bears the inlet pressure, and the length of the shell and the installation depth of the pump depend on the requirements for NPSH cavitation performance. The radial thrust ball bearings in the bearing housing rely on lubricating oil for lubrication. The constant position oil cup can automatically maintain the working oil level. The fluid dynamic radial sliding bearing is located at the inlet end of the pump. Shaft seals include single and double end mechanical seals, series mechanical seals, etc. The position of the suction pipe and discharge pipe is at the upper part of the installation flange, forming a 180-degree angle with each other. Other layout methods are also possible, such as a 90-degree angle. The motor drives the pump to operate through a flexible coupling, and the installation type of the motor is V1. From the direction of the drive end, the pump rotates counterclockwise. (150LDTN-100 pump is clockwise).
