Selection issues for low-flow, high-head pumps
Thread Content
For an experimental purpose, the material transfer pump is required to have a flow rate of 0.5–1 cubic meters per hour; the pump pressure can reach 0.8–1.2 Mpa, and the medium is phosphorus trichloride. At the moment, neither packed-sealed screw pumps (for leakage issues) nor magnetic screw pumps (for insufficient pressure) work. Could anyone help provide a solution?
Based on your requirements, a pump with low flow rate but high head is needed; you can consider the following options: 1. Self-priming pump: Self-priming pumps are suitable for transporting liquids or other fluids from a lower level to a higher one, without the need for priming or air release, which helps improve efficiency. For applications requiring low flow rates and high head, a self-priming pump is a good choice. 2. Submersible pump: A submersible pump is a type of pump in which the pump body is placed within the medium to be pumped; it can dissolve organic substances that are readily hydrolyzable. It has advantages such as low noise, no leakage, no vibration, and long service life, and is also suitable for transporting media with low flow rates and high head pressures. 3. Centrifugal pumps: Centrifugal pumps are generally suitable for transporting fluids such as clean water or slurries, but their structure can be modified to meet different requirements; for example, they can be made from corrosion-resistant materials to enable them to handle fluids with low flow rates but high head pressures. I hope the above suggestions will be helpful to you. It is recommended that you choose the appropriate pump type based on your actual needs and specific circumstances. .
Your reply is full of nonsense. 1 cubic meter, 120 meters – how many self-priming pumps and submersible pumps are available for use?
High-speed pumps, piston pumps, diaphragm pumps, rotary vane pumps
This flow rate is not small; a diaphragm pump will definitely work. More suitable for highly toxic media. If cutting isn’t possible, use a progressive cavity pump. Is the 2nd floor an A.I.?
The efficiency of the centrifugal pump is not high; it’s probably around 10. What is the density? Can I do a return shipment?
It is recommended to choose a pitot tube pump. Product parameters: Structure: Single-stage cantilever type; Design standard: API610; Flow rate: 0.5–160; Head: 80–1600; Temperature: -80°C–150°C; Pressure: 16
Hydraulic diaphragm pumps, piston metering pumps
It’s better to choose a screw pump of better quality; the prices of other pumps aren’t cheap either.
