Selection of low-flow, high-head pumps
Thread Content
Dear all**, the medium being transported is water, with a flow rate of 2.8 t/h and a head of 550 meters. How should I choose a pump for this application?
For multi-stage centrifugal pumps, which one offers the best cost-performance ratio?
Choose a high-speed pump; it’s more mature in terms of performance. For the lubrication system, it’s highly recommended to opt for one with an auxiliary oil pump – avoid those manual-type pumps!
The piston pump is still the most suitable option, as it offers high energy efficiency
Vane pump – the most suitable, inexpensive, and simple in structure. High-speed pumps are too expensive, and piston pumps are even worse – they have a high failure rate and are also costly. Moreover, the pressure they can generate isn’t high enough to warrant the use of piston pumps.
Plunger pump: convenient, simple, stable flow rate, low price...............
