Functional Specifications

SK 27-30 Submersible Pumps for Construction Site Drainage

The Speroni SK 27-30 are submersible drainage pumps developed to work in demanding conditions. Their cast iron structure ensures solidity and resistance, making them particularly suitable for professional use on construction sites, in civil engineering, and for drainage operations. The top discharge is designed to promote effective motor cooling, helping to maintain reliable performance during operation. The pumps can operate continuously when fully submerged.

Robust Construction and Resistant Materials

The Speroni SK 27-30 range uses selected materials to ensure reliability and durability. The pump body and motor cover are made of cast iron, while the impeller is constructed from a high-chrome alloy, suitable for professional use. The stainless steel motor shaft completes the structure. A particularly important element is the double silicon carbide mechanical seal in an oil bath, designed to offer high guarantees of durability and protection of internal components.

400 V Three-Phase Motor and IP68 Protection

The Speroni SK 27-30 submersible electric pumps are equipped with a 2-pole induction electric motor, powered by a 400 V - 50 Hz three-phase supply. The motor features Class F insulation and an IP68 protection rating, characteristics that support its use in applications with the pump fully submerged. The motor configuration is designed to offer operational continuity and reliability in professional drainage applications.

Resistant Materials for Professional Applications

The construction of the SK 27-30 is designed to ensure robustness and resistance. The pump body and top cover are made of cast iron, while the impeller is made of a high-chrome alloy. The stainless steel motor shaft contributes to the resistance of internal components. The silicon carbide mechanical seal in an oil bath completes a configuration designed for reliable and long-lasting use.
