Selection of low-flow pumps
Thread Content
I work in the catalyst industry, and I need to select a pump with a head of 20 meters; the lower the flow rate, the better. The fluid contains solid particles with a diameter of around 10 microns, the temperature of the fluid is between 35–40°C, and its pH level is 3.5. Which type of pump would be suitable for my needs? How to choose? Furthermore, the medium contains chloride ions and is somewhat corrosive; what material should be used for the flow-through components of the pump? Please ask an expert to help solve this! Thank you!

What is the viscosity of the substance, and what is its density?

Reply to 3# stove: Viscosity can be ignored; the density is around 40%. How should I make my choice?
Diaphragm pumps are chosen; they have a minimum flow rate of 0.8 cubic hours and a head of up to 50 meters. They are suitable for handling various corrosive liquids, liquids containing particles, as well as liquids that are highly viscous, volatile, flammable, or highly toxic

Reply to 6# saitai: Are diaphragm pumps a bit expensive? Is there a suitable centrifugal pump, or would a reciprocating pump work?
Reply to 9# bingyu1218: Pneumatic diaphragm pumps are not expensive. If a fluoropolymer centrifugal pump is used, with a head of 20 meters and a flow rate of 10 cubic meters, it will be more expensive than pneumatic diaphragm pumps; reciprocating pumps generate too high a pressure
For low flow rates and high head, high-speed pumps can be used.
