I am sure you are aware of the Goulds 3620 between bearings, radially split process pumps. But what about the new 3620 “Q” designated sizes? All the 3620 pump sizes ending with “Q” have been redesigned with new hydraulics. These new hydraulics are not intended to replace existing hydraulics but to augment our current hydraulic coverage.
All 3620’s still deliver smooth, reliable operation and fully meet the specification requirements of API-610. But now, available coverage resulting from the new “Q” selections will allow for the head rise and NPSH requirements most often required for your hydrocarbon processing applications falling within this product line.
We listened to our customers and corrected the hydraulic shortcomings on many of the 3620 models. The result is 18 new sets of hydraulics. The new performance curves are available on line at http://www.gouldspumps.com/pump_3620.html and can be accessed through the Pump Selection System (PSS). Again, these new hydraulics are not intended to replace existing hydraulics but to broaden and enhance our current hydraulic coverage.
