By safely processing untreated wastewater and fibrous debris, this robust unit is intended to support predictable circulation across demanding municipal distribution loops.\u003c\/p\u003e\u003cp\u003eHydraulic mechanics are specifically scaled to deliver a maximum flow output of approximately 648 L\/Min combined with a maximum vertical head of 16.8 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 kinetic blockages.\u003c\/p\u003e\u003cp\u003eUtilizing heavy-duty EN-GJL-250 cast iron, the external housing is designed to assist in resisting severe abrasive degradation. An intermediate non-toxic oil chamber serves as a dependable thermal buffer, intended to support the 0.9 kW single-phase 240v motor. This internal reservoir continuously lubricates the double shaft seal cartridge.\u003c\/p\u003e\u003cp\u003eWith a verified net weight of 41.8 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.
