Are these Excel spreadsheets compatible with Goulds 3196 and Durco Mark III pumps?
Yes — fully compatible. These tools are designed for ANSI B73.1 process pumps and apply to:
- Goulds 3196
- Durco/Flowserve Mark III
- All interchangeable ANSI pump models
All methodologies follow HI (Hydraulic Institute) and ANSI standards used across North America.
How do I calculate NPSH for a centrifugal pump?
NPSHavailable = Psuction + Static head − Vapor pressure − Friction losses
- Our free NPSH calculator handles all variables automatically
- Critical rule: NPSHa > NPSHr + safety margin
- Prevents cavitation damage in chemical process applications
What is the difference between static head and friction head in pump systems?
Static head: vertical elevation difference between suction and discharge liquid levels (independent of flow).
Friction head: energy loss from fluid flowing through pipes, fittings, and valves (varies with flow rate).
- Our hydraulic calculator computes both separately
- Sums them for total dynamic head (Darcy-Weisbach equation)
- Built-in friction factor & local resistance coefficient databases
Can I use these Excel tools for slurry pump selection?
Absolutely. Our Slurry Pump & VFD Selection Calculator is purpose-built for mineral processing and chemical slurry transport:
- Slurry rheology: weight/volume concentration, solids density
- Critical deposition velocity — prevents pipe blockage
- Viscosity effects on pump performance
- VFD optimization using pump affinity laws
- Worked example: carnallite & potassium-mixed salt slurries at industrial scale
