low flow rate centrifugal pump

[rotaryguy]

i am looking for manufacturer who produce centrifugal pump at 3 gpm which can be used as dosing pump how ever i can not use metering from Milton roy pumps as system is pulsation sensitive. is any body aware of any manufacturer who produces low flow rate centrifugal pumps?

Depending on your specific head requirements, many manufacturers make low flow pumps....Goulds has a LF3196 that can do 1 gpm; efficiency is terrible, but since hp is low, it's not a huge hp loss.

If you're looking for an ANSI design pump, pretty much all of the big names have a similar design.

What is the head (pressure) required?

 

[rotaryguy]

required head is 75 psi

The miton roy (or other such pumps) pump will not have a pulsation if you are mixing 3 gpm with 100 gpm. One version of the milton pump has a very long stroke and slow rpm.

As tenpenny has pointed out - any of the ANSI or similar pump models / manufacturers can achoieve this duty for you.

IF YOU WANT TO GET 3GPM @ 75PSI WITHOUT PULSATION AND A CONSTANT FLOW RATE THE BEST PUMP TO USE WOULD BE A PROGRESSIVE CAVITY PUMP. IT WILL WORK MUCH BETTER THAN A CENTRIFUGAL IN SUCH LOW FLOWS AND HIGH PRESSURES. WHAT IS THE PRODUCT YOU ARE PUMPING, TEMPERATURES, ARE THERE SOLIDS?

You might look at Viking, a maker of rotary pumps. They would be especially suitable for higher viscosity liquids.

Or a regenerative turbine pump - specifically designed for low flow/high head. Cheap as chips, great little pumps, reliable as i dont know what.

You may want to try Sundyne Pump. They're generally high head, low flow.

Rotaryguy,
Centrifugal pump should be always the first shot, but
no always can meet any rated point.
