Product Overview
Addressing long-term operating cost scaling, the SL1.50.65.11.E.Ex.2.50B non-self-priming, single-stage, centrifugal pump designed for handling wastewater, process water and unscreened raw sewage delivers reliable energy efficiency. Built to operate consistently in continuous submerged installations, the system supports dedicated commercial wastewater transfer stations.
Constructed with an EN-JL-1030 cast iron pump housing, the internal architecture withstands prolonged mechanical stress. The heavy-duty cast iron motor house ensures substantial protection for delicate components while fully submerged. A specialized SiC/SiC primary shaft seal provides a resilient barrier against fluid ingress, protecting the drive shaft in harsh applications.
This submersible wastewater pump provides a maximum flow of 834 L/Min and a maximum head of 12.6 m. Powered by a 1.1 kW motor requiring a 415v three-phase power supply, the unit operates at a rated current of 3.1 Amps. With a net weight of 59.5 kg, the unit is configured to be suitable for guide rail installations using an automatic coupling arrangement.
Engineered for hazardous environments, this explosion-proof configuration incorporates AUTOADAPT technology, allowing the unit to run autonomously without external control boxes. The EN 12050-2 approval confirms its capacity to handle unscreened sewage. A stainless-steel clamp assembling system permits rapid disassembly, streamlining routine inspections.
