Centreline-supported single-stage end-suction overhung pumps shall be designated pump type OH2. This structure eliminates the misalignments of the coupling in high temperature applications resulting in lower unexpected shutdowns and maintenance.
High temperatures, high pressure fluids - the extreme conditions in the petrochemical and chemical industries require sophisticated and often complex solutions. Thanks to professional manufacturing and comprehensive service, our high-quality OH2 Centerline Mounted Chemical Centrifugal Pumps maximize performance and reliability.
The Features of OH2 Centerline Mounted Chemical Centrifugal Pump:
1. Volute casing and impeller offer high hydraulic efficiencies for reduced energy consumption2. The Centerline supported case and base plate are crucial components, which can effectively prevent distortion and misalignment caused by high temperature and pressure, ensuring the stability and reliability of the equipment under extreme conditions.
3. High interchangeability of pump parts reduced the cost on spares parts for clients.
4. The seal chamber is compatible with multiple sealing configurations and is suitable for various operating environments, including the most demanding working conditions. A full complement of API 610 seal flush piping plans is available, ensuring reliability in different application.
5. The auxiliary device for mechanical seal transforms severe working conditions into an environment suitable for the operation of mechanical seals, enhancing the performance of mechanical seal and the safety factor of equipment operation, making zero leakage of the medium possible.
We committed to the design and production of chemical centrifugal pumps, optimize the flow channel design, select the appropriate materials, and configure effective mechanical seals, all of this in order to extend the service life of chemical centrifugal pumps.
Pump Configuration:
We have eight modernized workshops covering 12,000 square meters, which producing ability was designed as 18000 pieces per year. The factory consists of foundry workshop, finish-machining workshop, plate welding workshop, assembly workshop and testing center. The maximum lifting ability for tramelling crane is 50 metric tons; There are 510 sets of large and essential processing facilities which enable the requirements for producing all kinds of industrial pumps.
Casting of parts and components is an important part of the industrial pump production process. The precise control of the pump material smelting and the flow path size of the over-current components is our key control program for the quality of the pump products. The annual production capacity of 8,000 tons of alloy cast iron and dozens of new casting equipment such as AOD refining furnace and spectrum analyzer, as well as a group of skilled stylists, ensure the excellent quality of our castings.
