Flow rates and pressure formula for gland water service.
Flow rates and pressure formula for gland water service.
(OP)
I am in the midst of commissioning a mill which will extract gold. Question is; where can I find a formula for gland water service on a 14" by 12" slurry pump which will feed slurry to the cyclone pack 3 levels up?

It is a capital mistake to theorise before one has data. Insensibly one begins to twist facts to suit theories, instead of theories to suit facts. (Sherlock Holmes - A Scandal in Bohemia.)

I know you have some mining experience, you are correct;slurries are variables, pressures fluctuate in addition, we are running a vfd which adds to the situation of "getting it right". I have 24GPM going into a 1 inch pipe to the stuffing box, there is, however, some concern as to the amount of water being added to the slurry process. It is Warman pump, tried , true and tested. We are, however, just running water in a loop for the commissioning, we just noticed some steam and probably some cavitation as there is a "witches hat" in the intake pipe(for construction debris.... this will be removed for normal service. We have set the flow rate per Warman.
Thanks again!!!

24 gpm sounds like quite a lot to me for a stuffing box flush, but it that's what the vendor says then go with it. I would try and get a reasonably high pressure supply ( higher than your max inlet pressure) turned down before your pump so that any changes in the inlet pressure don't really affect the flow.
