Hydraulic balancing disc

Hydraulic balancing disc

Hydraulic balancing disc

(OP)
Does anyone knows the calculation method for sizing the hydraulic balancing discs in multistage pumps and a material for hydraulic balancing discs resistable for sandy water?

RE: Hydraulic balancing disc

Sorry, but I cannot help you right now with sizing the balancing disc, but I can comment on the sand issue.

A balancing disc or drum works by providing a "tretcherous path" (pardon my spelling) for the water to flow.  For it to properly work, you need *tight* clearances.  For this reason ALONE, you should NOT use such a balancing device when you have a solid-containing fluid.  In other words, do not use a balancing disc or drum.

Regards,
Tim
