Sizing flow-regulators

Sizing flow-regulators

Sizing flow-regulators

(OP)
Greetings,

I am needing to size a flow-regulator for a pulsation dampener pumping system.

Does anyone have any good references to do this or perhaps some tips from performing similar tasks yourself?

Thanks for your help.

RE: Sizing flow-regulators

To clarify,

It is a reciprocating, positive displacement, diaphram pumping system that has a pulsation dampener fitted.

Cheers.

RE: Sizing flow-regulators

If it's a positive displacement pump, your best way to regulate/control flow is by controlling the pump's speed or stroke using a flowmeter or by feedback from a tank weighscale.

If you don't want to do that for some reason, you can use the pump as a mere pressure source by putting a back-pressure regulator on a tee in the discharge line, directed back to the tank, sized for the full output of the pump (note- not the suction of the pump- that may cause overheating due to recirculation).  Then you size a control valve/flowmeter combination for the forwarding line as usual.
