Product Overview
Built from premium cast iron to maximize environmental endurance, the EF30.50.11.E.Ex.2.50B Grundfos EF AUTOADAPT pump is a portable pump for both domestic and industrial applications. This high-capacity drainage unit utilizes embedded self-calibrating logic, dynamically managing dry-running sensors straight from its internal array.
Flow dynamics are explicitly tuned to generate a stable flow rate of approximately 666 L/Min alongside an impressive maximum vertical lift of 17.9 meters. Processing commercial fluids effectively, the system utilizes a single-vane semi-open impeller that maintains a 30 mm free passage, helping to mitigate the buildup of thick fibrous materials.
The architectural framework features a resilient EN-JL-1030 cast iron casing intended to protect internal electronic sensors. To preserve the 1.1 kW three-phase 415v motor during intensive cyclic loads, an intermediate oil chamber provides thermal dissipation while simultaneously lubricating the fast-replacement double shaft seal cartridge.
Weighing 46.4 kg, this explosion-proof certified machine is developed for safe deployment in regulated hazardous industrial facilities. It is suitable for guide rail installations utilizing an automatic coupling arrangement aligned to P/N 97644486 to enable service extraction without wet well entry. High-grade polyurethane potting secures the main cable.

During heavy wastewater influx, what maximum fluid volume passes through this submersible assembly?
Under peak inflow conditions, Grundfos EF30.50.11.E.Ex.2.50B delivers a maximum volumetric throughput of 666 L/Min.
Within regional wastewater pumping sumps, what vertical fluid lift is sustained under peak delivery duty?
Operating in regional wastewater sumps, EF30.50.11.E.Ex.2.50B sustains an operational dynamic head of 17.9 m.
What are the motor power output, phase voltage connection, and running current draw for this unit?
The electric drive in EF30-50-11-E-Ex-2-50B delivers 1.1 kW across a three-phase 415 V operational feed, drawing 3.1 Amps at full load.
What internal clearance dimension prevents solids obstruction across this semi-open pump casing?
Internal volute geometry in EF30 50 11 E Ex 2 50B sustains a 30 mm spherical through-let, preventing particulate accumulation in collection sumps.
How does the internal control architecture adapt pumping intervals to community inflow surges?
Self-monitoring routines in EF30/50/11/E/Ex/2/50B eliminate separate starter cabinets, while compatibility with the Grundfos auto-coupling system (97644486) facilitates rapid hoist maintenance.
