Premium EN 1561 EN-GJL-250 cast iron defines the impenetrable exterior of the SL1.95.100.220.4.52H.N.51D.A.T, delivering resistance against submersed wear. Incorporating a 150 mm inlet and 100 mm outlet, this pump locks in structural integrity for municipal treatment plants. Operating within flooded pits, the asset manages severe fluid surges without compromising infrastructure.
Buried at the center of this thick metallic housing lies a precision-cast S-Tube impeller governed to maintain a massive 95 mm free passage. This internal clearance proves critical for capturing and relocating solid-heavy municipal sewage without stalling. By neutralizing dense blockage risks at the transfer layer, the circulation loop safely spares public facilities from overflow events.
Supplying kinetic force is an efficient 22 kW Grundfos 4-pole motor wired into a standard 415v three-phase grid. This assembly outputs an impressive maximum head of approximately 29 m, accompanied by capacities peaking at 4986 L/Min. The carefully structured fluid velocity paths efficiently harness this energy.
Solidifying its highly protective profile, the system houses sensitive moisture sensors and motor-protection thermistors natively within the core. These reactive monitoring components constantly trace the sealed motor cavity, building a defensive wall against submersed breaches or thermal overloads.
Features
- Utilizes a state-of-the-art cable entry connector that allows the fifteen-meter heavy waterproof cord to be fully disconnected without removing the upper motor casing.
- Features an easily accessible double shaft seal configured in a dedicated cartridge design, permitting rapid maintenance interventions without heavy specialized equipment.
- Manufactured with a highly durable secondary shaft seal built from an ultra-tough silicon carbide and carbon friction material configuration to isolate the internal core.
- Built using premium EN 1561 EN-GJL-250 cast iron across the main pump housing and exterior motor shell to ensure maximum mechanical resilience in flooded environments.
- Designed to seamlessly process immense fluid loads continuously at dense temperature ranges from ten to forty degrees Celsius within permanent municipal networks.
- Engineered to safely endure a maximum continuous installation depth of twenty meters while preserving an absolute eight bar internal operating pressure tolerance.
