Where can I find boiler feed pumps with low flow rate and high head?
Thread Content
Boiler feed water pump: Medium – boiler feed water (deoxygenated water); Temperature: 105 degrees; Head: 500 mH2O; Flow rate: 1–1.5 m3/h. Are there any manufacturers of this type of pump in China?
Is a head of 500 meters that high? This estimate requires customization and two units stacked together; it’s not possible with just one unit
It’s easy to achieve a pressure of 5 MPa at 1,000 liters to 1,500 liters
High-speed pump or Flowserve’s low-flow multi-stage pump
You might consider this one, the smallest model
Give priority to high-speed pumps; they are widely used by Beijing Aerospace.
Why isn’t the operating temperature of the fluid included in the sample?
There are two types of pumps that can be considered for this purpose: piston pumps, but these generate pulsations; and venturi pumps. There are many cases abroad where venturi pumps are used as boiler feed pumps, and there are also quite a few such examples in China. If possible, please contact via WeChat (phone number): 13162294857
It is recommended to use a venturi pump, which is known as a rotary shell pump in China; it is the most suitable for applications requiring low flow rates but high head pressures. In China, this type of pump is produced by Sichuan Nikki
