Product Overview
Delivering exceptionally stable hydraulic force for deep well networks, the EF30.50.15.Ex.2.50B Grundfos EF pump is a portable pump for both domestic and industrial applications. The system helps manage the continuous transfer of untreated effluents, providing predictable routing for facilities facing volatile sub-surface challenges.
Hydraulic mechanics are specifically tuned to deliver a maximum flow output of approximately 774 L/Min combined with a maximum vertical head of 22.5 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 1.5 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.
