Question: How much should you reduce the pump R.P.M. in order to get less flow?
Answer: Required R.P.M. = Expected flow x Max R.P.M. allowed
Max allowed flow
Question: Which diameter the engine/ motor pulley should have to achieve these R.P.M.?
Answer:
External diameter of the motor pulley =
External diameter of the pumps pulley x pump R.P.M.
Engine/motor R.P.M.
Question: What’s happening if it is not possible to replace the engine/motor pulley?
Answer: External diameter of the pump pulley =
External
diameter motor pulley x engine/motor R.P.M
Pump R.P.M.
Question: If the engine/ motor is running at lower R.P.M. than the max. R.P.M indicated in
the label, which is the maximum flow rate to achieve?
Answer: Attainable maximum flow =
Engine/motor R.P.M: x Max. flow indicated in the label
Max. R.P.M. indicated in the label
Question: What is the approximate power required to achieve the max. performances
allowed?
Answer: Required power (kw) = Max flow (L/min) x Max pressure (bar)
