Pump Fundamentals
Pump Engineering Fundamentals
A short, practical guide to the engineering that decides whether a centrifugal process pump will run efficiently and reliably in your service. Each topic ends with the data we need to turn it into a pump selection, so the fundamentals feed straight into a quotation.
NPSH and Cavitation
Why suction conditions and liquid temperature decide whether a pump cavitates, and how to keep a safe margin.
Pump & System Curves and BEP
How the pump curve and your piping set the operating point, and why running near the Best Efficiency Point matters.
Viscosity and Slurries
How viscosity, solids and abrasion change performance, power and material choice.
Pipe Friction and System Head
How static head and friction combine into the duty point a pump is selected against.
How the Fundamentals Feed Your Selection
Across all four topics, the same handful of figures drive a correct selection: the required flow and head, the liquid with its temperature, viscosity and any solids, the suction conditions, and the piping. Gather those and a pump can be matched to your duty against a reviewed curve rather than a nominal chart. The selection guide lists the full checklist, and the FAQ answers the common questions.
Standards, Seals & Ownership
ANSI / ASME B73.1 Explained
What the process-pump standard fixes, back pull-out design and why interchangeability matters to buyers.
What Is an ANSI Pump?
The B73.1 pump type: design features, typical uses, materials and how it differs from ISO and API pumps.
ANSI Pump Size Codes
How to read codes such as 2x3-13 and 3x2-13, and convert between the Goulds 3196 and Durco Mark 3 patterns by designation.
ANSI, ISO and API Standards Compared
Which of ASME B73.1 to B73.3, ISO 2858, ISO 5199 and API 610 fix dimensions, and what that means for a replacement.
Mechanical Seals for Process Pumps
How seal arrangement, chamber and face materials are chosen for the liquid and duty.
Efficiency & Cost of Ownership
Why energy and maintenance dominate lifetime cost, and how correct sizing lowers it.
Ready to Select a Pump?
Send your duty point and liquid data and we review it against real pump curves for the G196 and D Mark III series.
This is general engineering guidance for buyers of ANSI/ASME B73.1 process pumps. Final selection always depends on your verified duty point, liquid data and installation conditions. Send your data for a reviewed proposal.
