Product Overview
Engineered to assist with processing heavy fluid volumes in rigorous industrial setups, the EF30.50.11.Ex.2.50B Grundfos EF pump is a portable pump for both domestic and industrial applications. It operates smoothly under intense mechanical stress, helping to manage commercial wastewater safely across complex elevation changes.
Hydraulic mechanics are specifically tuned to deliver a maximum flow output of approximately 738 L/Min combined with a maximum vertical head of 20.9 meters. Processing fluids through a 50 mm port, the system utilizes a single-vane semi-open impeller maintaining a rigid 30 mm free passage, helping to prevent the accumulation of fibrous materials.
Built primarily from heavy-duty EN-GJL-250 cast iron, the external housing is designed to assist in preventing abrasive degradation. An intermediate non-toxic oil chamber serves as a dependable thermal buffer, intended to support the 1.1 kW three-phase 415v motor. This internal reservoir continuously lubricates the double shaft seal cartridge mechanism.
With a verified net weight of 42.0 kg, this explosion-proof certified unit operates securely within hazardous environments. It supports guide rail installations utilizing an automatic coupling base matching P/N 97644486, permitting rapid extraction access without requiring personnel entry. A polyurethane potted cable plug tightly limits moisture intrusion.
