Pump Flow Rate

Give these people a ring, and talk to them:

I tried www.silverson.com/ but they do not have any mention of this pump. How old is this pump? May be they did not make it but outsourced it. You already have the flow rate = 450 litres per minute. You can always measure the pressure. 2080 may be the year of manufacture of the pump.

"2080 may be the year of manufacture of the pump..." - only if someone's found the keys to the KrisDel™ Time Machine . I though they went down the plug-hole.

I think more than 10 years. that is why i am here to seek expertise.

It's not a pump. It's a mixer.

Thanks, lyn. I thought as much. How strange that the OP does not know what he has & what he wants?

"How strange that the OP does not know what he has & what he wants"

Actually that's all too normal for OP's here.

So. This is a mixer and not a pump (see #6↑).

So the flowrate is whatever the [something else] is passing through it.

This is a Mixer Homogeniser. Contact them and ask them what ever info you need. They might (or should be able ) to give you a copy of the specifications for this mixer.

A very easy task: Obtain the performance curves for that exact model, size and speed pump from the manufacturer. Read the suction and discharge pressures with the pump operating. Enter the difference of the two pressures onto the curve shown for the appropriate speed and that curve will tell you the volume pumping in gallons/liters per minute. The BHP will be shown for water. For fluids of a specific gravity different than water, the volume will remand the same but the BHP will change accordingly. Your pump supplier can help you with all this.
