The physical density of an exterior mechanical housing determines the overall survivability of fluid machinery submerged in volatile processing centers. Constructed entirely around an ultra-dense casing, the Grundfos SE1.80.80.75.4.50B.B is an elite non-self-priming, single-stage, centrifugal pump designed for handling wastewater, process water and unscreened raw sewage.
This uncompromising cast iron barrier provides exceptional resistance against the highly abrasive forces and rapid pressure spikes typically found in deep commercial collection pits. Shielding the internal electromechanical elements from continuous exposure to suspended liquid contaminants, the rigid structure completely prevents microscopic structural warping while securing the operational envelope.
Advanced hydrodynamic acceleration is achieved through a specialized S-TUBE impeller configuration, guaranteeing the unimpeded passage of heavy suspended solids. Utilizing a massive 7.5 kW motor connected directly to a strict 3-phase 415v power grid, the system smoothly scales to an approximate maximum head of 23 m alongside an approximate continuous flow volume of 3300 L/Min through its 100 mm entry and 80 mm exhaust ports.
Maintaining absolute thermal equilibrium is executed by an autonomous liquidless maintenance-free cooling layout, actively supporting continuous running cycles within flooded or permanently dry installation spaces. An innovative stainless-steel clamp assembling protocol guarantees the entire motor unit can be rapidly decoupled from the pump base for immediate internal service access without heavy industrial tools.
Features
- Secured by an IP68 standard enclosure housing specifically optimized to block external moisture penetration in flooded subterranean pits.
- Safely supports continuous long-term deployments at a maximum certified installation depth measuring up to 12 m underground.
- Features a heavy-duty 15 m Lyniflex power cable explicitly configured to secure versatile remote facility grid connections.
- Maintains superior internal electromechanical integrity utilizing a certified premium Class F electrical insulation standard rating.
- Manufactured with an overall substantial total machine weight measuring exactly 222 kg to drastically minimize operating vibration.
- Rated to reliably operate internal shaft rotations at an exact operational speed of 1455 rpm under peak loading conditions.
- Actively sustains a strict maximum operating environmental fluid pressure parameter measuring up to 6 bar dynamically.
