Construction Drainage Pumps(1.5 HP to 10.0 HP) 50Hz.

Product catalog summary

Overview: The LAS Construction Drainage Pumps are designed for civil engineering applications, particularly for dewatering in tunneling, ground works, and storm water sewers. These pumps are suitable for handling fluids with solid sediments and are available in power ranges from 1.5 HP to 10.0 HP.

Performance Range: The pumps offer a flow rate of up to 2500 liters per minute (150 m³/hr) and a dynamic head of up to 37 meters.

Design and Features: The pumps feature a heavy-duty, lightweight, top discharge design that is easy to handle. They have a double outer casing with a water-cooled motor, making them suitable for low water level applications. The structure is fully waterproof with an IP68 rating and includes high-grade silicon carbide double mechanical seals. The impeller is made from high chrome alloy (HCR) steel, providing resistance to abrasive applications.

Specifications: The pumps are available in both single-phase and three-phase models, with voltage options of 1Ph. 230v and 3Ph. 400v. They include a thermal overload protector with an automatic reset motor protector to prevent motor damage due to high temperature, phase failure, voltage drop, or locked impeller.

Materials: Key materials used in the construction include AISI-304 for the outer cover, grey iron for the casing, and hard ductile iron for the impeller. The mechanical seals are made from carbon versus ceramic and silicon carbide versus silicon carbide.

Optional Features: The pumps can be customized with different voltages and are available in 60Hz. Discharge connections can be hose, flange, or thread.

Performance Data: Performance charts indicate the pumps' capabilities at 2900 RPM, with various models offering different flow rates and head heights. The LAS models range from 21A15 to 61035, with specific performance metrics provided for each model.

Applications: These pumps are ideal for dewatering in civil engineering projects, particularly where a robust and efficient solution is required for handling wastewater and sewage with solid content.
