What pump should be used to transfer material containing 10% solid particles?
First, what material? Basic parameters such as temperature, flow rate, head, and specific gravity are needed so that I can help you make a choice!
Material with 10% solid particles is pumped using a slurry pump
For a pilot-scale project, the particles serve as catalysts; the flow rate is not very high, and the feeding height is within 15 meters. Should a centrifugal pump, diaphragm pump, plunger pump, or some other type of pump be used?
This one? Can it be used in the pharmaceutical and chemical industries?
Among these three pumps, the centrifugal pump and diaphragm pump are inexpensive and can meet the requirements. Open impeller for centrifugal pumps
What is the pressure in your system as well? ! ! ! ! ! ! ! ! ! ! ! !
An open impeller centrifugal pump will do; diaphragm pumps must not be used at all
Oh, why is it said that diaphragm pumps can’t be used?
If you study the structure of diaphragm pumps, you’ll see that they have check valves at both the inlet and outlet, which limits their use in liquids containing solids
The inlet and outlet of the diaphragm pump each have two balls; one must be open and the other closed for continuous discharge, otherwise, without a pressure difference, no material can flow in. . . . . Well, if there is corrosion, you should choose a mortar pump from the UHB series or a slurry pump of type 2PNJA; in the absence of corrosion, you can opt for an alloy centrifugal pump or a regular carbon steel centrifugal pump. Alloy pumps tend to be much more expensive.
