TDOW Double Suction Pump
Product Description
The TDOW double suction pump can be used in a wide range of general purposes and industries. When selecting the right pump for a job, one must consider several technical and economic points, particularly with regard to safety, economy, and applicability, including the following:
- Flow rate and head (the intersection of the device characteristic curve and the pump performance curve) must be easily maintained to increase efficiency, reduce power consumption, and reduce wear and tear on the pump parts.
- The selected double suction pump should be long-working and efficient.
- The selected pump should have good anti-cavitation performance, stable operation, and long life.
When narrowing down a selection for a specific purpose, the following factors should also be considered:
- A user should know the characteristics of the medium to be pumped, including the diameter of the particles contained in the medium, the content of the medium, the temperature of the medium, and the required flow pressure of the pipeline system.
- The capacity and the head
a. If the minimum, normal, and maximum flows have been given in the production process, the maximum flow should be considered.
b. If the only normal flow is given in the
production process, a margin slightly beyond should be considered.
c. For large pumps with ns> 100 and low unintentional head pumps, the flow
margin is 5%. For small flow and high pumps with ns <50, the flow head is
10%. For pumps with 50≤ns≤100, the flow head is Take 5%. For pumps with poor
quality and poor operating conditions, the flow margin should be 10%.
d. If the basic data only gives weight flow, it should be converted into volume
flow.
Product Features
Main Application
- Compact structure, attractive appearance, good stability, and easy
installation.
- The optimally designed double-suction impeller reduces the axial
force to a minimum and has a blade-style with excellent hydraulic performance.
- Both the internal surface of the pump casing and the surface of
the impeller are precisely cast, extremely smooth, and are highly resistant to
vapor corrosion. - The pump case is double-value structured, which greatly reduces
radial force, lightens the load on the bearings, and increases efficiency.
- SKF and NSL bearings are used to guarantee stable running, low
noise, and long operational duration.
- The shaft seal uses Bergmann mechanical or stuffing seal to ensure
an 8000h life with no leaks.
This model double suction pump is suitable for use in waterworks, the petroleum, chemical, and power industries, metallurgy, mining, air-conditioning circulation, building, agricultural and urban irrigation and drainage, electric power stations, industrial water supply systems, fire-fighting systems, and shipbuilding.
