Product Overview
The absolute integrity of the external structural housing fundamentally dictates the operational lifecycle of machinery deployed inside volatile fluid processing centers. Built specifically upon an ultra-dense casing, the Grundfos SE1.100.100.55.4.50B.B serves as a premium non-self-priming, single-stage, centrifugal pump designed for handling wastewater, process water and unscreened raw sewage.
This uncompromising cast iron metallurgical barrier aggressively deflects the abrasive mechanical forces and rapid fluid pressure spikes incredibly common in deep subterranean collection environments. By completely shielding the sensitive electromechanical drive elements from continuous exposure to suspended liquid contaminants, the rigid structure preserves absolute geometric alignment across the active envelope.
Advanced dynamic internal fluid velocity and thermodynamic stability are accurately governed by a specialized S-TUBE impeller configuration, effortlessly guaranteeing the free passage of suspended heavy solids. Utilizing an energetic 5.5 kW motor connected to a 3-phase 415v grid, the system consistently scales to an approximate maximum head of 16.2 m alongside an approximate flow volume of 4284 L/Min using 150x100 mm lines.
Maintaining absolute internal thermal equilibrium is flawlessly executed by an autonomous liquidless maintenance-free cooling layout, actively supporting continuous heavy running cycles within submerged or totally dry installation spaces. An innovative stainless-steel clamp assembling protocol guarantees the primary motor unit can be smoothly decoupled for immediate internal access without deploying heavy dismantling tools.
