Speroni SK 70-80-85 - Submersible Pumps for Construction Site Drainage and Civil Engineering
The Speroni SK 70-80-85 submersible electric pumps are designed for professional drainage of construction sites, civil engineering works, and applications where water needs to be moved continuously, reliably, and efficiently. Made with robust components and selected materials, these submersible drainage pumps combine high performance, resistance, and durability. The cast iron construction of the pump body and motor cover ensures solidity, while the high-chrome alloy impeller is designed to handle demanding working conditions. The top discharge system facilitates motor cooling during operation. The double mechanical seal in silicon carbide, installed in an oil bath, further contributes to reliability and protection.

Functional Specifications
SK 70-80-85 Submersible Electric Pumps for Construction Site Drainage
The Speroni SK 70-80-85 are cast iron submersible electric pumps developed for construction site drainage. The range is designed for professional applications requiring continuous operation and efficiency. The pumps can be used for general drainage, offering a robust solution for water evacuation.
Robust Construction and Durable Materials
The structure of the Speroni SK 70-80-85 submersible electric pumps is made with materials chosen to withstand demanding working conditions. The pump body and motor cover are made of cast iron, while the impeller is made of a high-chrome alloy. The stainless steel motor shaft contributes to the overall resistance. This configuration makes the pumps suitable for professional drainage on construction sites.
Top Discharge and Motor Cooling
A characteristic feature of the SK 70-80-85 series is the top discharge, designed to promote effective motor cooling during operation. The pumps are also equipped with a double mechanical seal in silicon carbide, installed in an oil bath. This solution offers high guarantees of durability and helps protect internal components.
Three-Phase Motor and Continuous Duty
The Speroni SK 70-80-85 electric pumps use a 2-pole induction electric motor, three-phase 400V-50Hz, with Class F insulation and IP68 protection rating. The design allows for continuous duty with the pump fully submerged. The maximum immersion depth reaches 25 meters with an adequately long cable.
