Low flow rate, high head
Thread Content
1. I would like to ask which pump manufacturers can produce pumps with low flow rates and high head, excluding metering pumps. Flow rate of about 1-2 cubic meters; Yang Cheng is about 400 meters away
High-speed pump, rotary jet pump (pitot tube pump)
You can consult Beijing Cruise and Beijing Aerospace Petrochemical; we are using high-speed pumps from these two manufacturers here, but they do not have the specifications you mentioned.
High-pressure plunger pump/diaphragm pump~~~
Sulzer’s rotary vane pumps are designed specifically for such operating conditions
It depends on the properties of the liquid and the temperature. For conventional liquids, a high-pressure three-plunger diaphragm pump can handle the task easily; it is a seal-less pump similar to a three-plunger pump. Compared to metering pumps, it has almost no pulsation. Compared to high-speed pumps, the power-to-volume ratio is very low.
