Product Overview
Operating within demanding drainage environments, the SL1.50.65.15.Ex.2.50B non-self-priming, single-stage, centrifugal pump designed for handling wastewater, process water and unscreened raw sewage addresses operational load challenges. The assembly supports liquid transfer in commercial facilities, operating optimally in continuous submerged installations.
Constructed with an EN-GJL-250 cast iron pump housing, the architecture is engineered to endure aggressive fluid dynamics. The cast iron motor house provides structural protection for internal mechanisms while submerged. A SiC/SiC primary shaft seal acts as a resilient barrier against fluid ingress, intended to support the lifespan in raw sewage applications.
Evaluating hydraulic paths, this submersible wastewater pump achieves a maximum flow of 1170 L/Min and a maximum head of 16 m. Driven by a 1.5 kW motor requiring a 415v three-phase power supply, it draws a rated current of 3.8 Amps. Registering a net weight of 55.3 kg, it is suitable for guide rail installations using an automatic coupling arrangement.
This explosion-proof configuration is intended to support safety in hazardous environments. The EN 12050-2 approval verifies its capability to handle unscreened sewage. Utilizing a stainless-steel clamp system, the pump allows direct maintenance access without special tools, helping manage downtime during routine facility evaluations.
