Pump Engineering Resources
Technical guides, worked sizing examples, troubleshooting resources and application engineering for progressive cavity and centrifugal pumping systems.
Use ACCA’s engineering library to select pumps, evaluate viscosity and abrasion, determine pressure and solids-handling requirements, diagnose operating problems and identify replacement components. For commercial product navigation, explore industrial pumps and pump solutions, industrial pump parts, or ACCA’s progressive cavity pumps.
Core Pump Engineering Guides
Progressive Cavity Pump Selection & Sizing
The master selection workflow covering flow, pressure, solids, abrasion, viscosity, materials, stages, drive-end selection and horsepower.
Progressive Cavity Pump Troubleshooting
Diagnose startup problems, loss of suction, reduced capacity, noise, seizure and uneven flow using symptom-and-cause troubleshooting tables.
Worked Pump Sizing Example
Follow a complete 40 GPM raw-sewage selection at 125 PSI from application data through element, stages, speed, drive end and horsepower.
Progressive Cavity Pump Selection References
Maximum Particle Size & Solids Handling
Use particle size and pump-element geometry to establish the minimum practical element size for solids-bearing service.
Speed for Abrasive Fluids
Understand how abrasion severity changes recommended pump speed and why larger elements at lower RPM can improve wear life.
Speed for Viscous Fluids
Review cavity filling, viscosity-related speed limits and the relationship between displacement, RPM and viscous-fluid performance.
Pressure per Stage
Determine how elastomer selection, element size and abrasion severity affect allowable differential pressure per stage.
Drive-End Pressure & Horsepower Limits
Connect the selected pumping element and pressure duty to drive-end capability, torque and HP-per-100-RPM limits.
Stator Elastomer Compatibility
Screen stator materials around fluid chemistry, temperature and service conditions before final compound selection.
