Low flow and high head! OH6 or a Reciprocating Pump?
Low flow and high head! OH6 or a Reciprocating Pump?
(OP)
In the following condition:
Diff. Head = 270m
Rated Flow= 14.3 m3/hr
Viscosity= 0.2027 Cp
I've selected OH6 pump but a friend of mind said a reciprocating pump may also meet these conditions.
Is there any preference (technical of economical) to choose between these two types of pumps?
Thank you all!

The more detail you give, the better answer you will receive; and vice versa.
WOuld be helpful to see:
fluid, SG, solids?, temp, lots of starts/stops?, etc.

All in all at these sorts of head and flow I would go for a centrifugal unless you have big variations in head
My motto: Learn something new every day
Also: There's usually a good reason why everyone does it that way

In this case the pressure isn't variable and it seems that Cent. pump is a better choice.

I only used OH6 when absolutely necessary.

I thought that between bearing pumps are generally large and are used when the capacity and head are high.
You mean that BB1, BB2, BB3 or even BB5 could be used for low flow? (like 40~60 gpm)

MultiStage Radial Section or Ring section called BB4 with acceptable effy of 40%.
OH2LF - Low Flow could do it, but very low effy , around 12%.
