Selection and ordering
Maximum flow and maximum pressure are separate ratings. Confirm the fluid, temperature, required flow, discharge pressure and complete configuration before selection.
For a configuration check, provide the complete pump model, fluid composition, concentration, operating temperature and duty point. Wetted-material compatibility must be confirmed for the intended service.
Photographs identify the series structure. They do not verify the internal diaphragm material or every ordering option. Maximum flow and maximum pressure are separate ratings.
