Dynamic load calculation for PD Pump
Dynamic load calculation for PD Pump
(OP)
Hi Guys,
I have few doubts and new your advise. Am referring to PD Pumps (Internal Gear)
There was this question from my customer which am not getting a satisfactory reply from the manufacturer.
1. What does dynamic load imply to PD pumps?
2. How to calculate Dynamic load?
Thanks in advance.

Gear pumps tend to be quite smooth so maybe the level of variation is low.
But maybe you or your client is referring to a different "dynamic load".
Difficult to know.
Vendor data is normally the only way to get any such loads.
Remember - More details = better answers
Also: If you get a response it's polite to respond to it.

Noted. But how do you calculate the dynamic load for PD pumps?
LittleInch,
There is no clear representation / requirement from my customer about dynamic load. I am not sure if this is used for centrifugal pumps either.

Is there any formula / handbook which we could refer to calculate the dynamic load?

Measurement of the system pressures will tell the level of these peaks and also the troughs in this ripple.
Use that min and max pressure to determine the cyclic torque applied to the pump.
Torque is pressure x displacement / 20 PI
