PlexSizing takes an ESP design from well data to a pump, motor and cable you can defend — in your browser, with nothing to install. Choose equipment from a maintained catalogue, check how it performs, compare candidate designs side by side, and print the report your team and customers expect.
Sizing
Enter well, fluid and production data and size the pump, motor, protector and cable. Design alarms and a clear summary show you what needs attention.
Performance
See the pump corrected for your fluid, frequency and flow, with the operating range and your target point marked on the curve.
Comparison
Put two or three candidate pumps side by side on the same duty and pick the best fit with confidence.
Scenario analysis
Change frequency, intake pressure, temperature or viscosity and compare up to ten cases against the base design.
