DFG50-200A/2/4 — Factory-selected Configuration

This DFG configuration is documented by a dated factory selection with a trimmed impeller. The displayed hydraulic point, motor and connection details describe that selection. They do not define every unit carrying the same model designation.

When to consider this equipment

Consider this configuration for clean-water supply or circulation after checking the new duty. The selection records fluid temperature, density and viscosity; its medium-name field is blank. Confirm the actual fluid and compatibility before ordering.

What to include in an enquiry

Provide the required flow and head, fluid and temperature, inlet pressure, available electrical supply, pipe connections and operating mode. Reference the full DFG50-200A/2/4 designation. Confirm the hydraulic duty and installation fit against the factory selection; the recorded point does not establish a complete pump curve.
