Overview

The KA-2.4 is a rugged submersible drainage pump designed for clean and dirty water transfer, sump drainage and light construction-site dewatering.

Built with a solid aluminium motor housing, cast iron pump casing and impact-resistant PVC strainer base, it is designed to withstand more demanding handling and working conditions than a typical household drainage pump.

Its semi-vortex urethane rubber impeller offers good wear resistance when pumping water containing suspended sand and silt, making it a practical choice for site drainage, basements, sumps and general water removal.

The KA-2.4 is supplied with an external float switch for automatic operation and a 10m electrical cable.

Key features

• Rugged aluminium and cast iron construction
• Semi-vortex urethane rubber impeller
• Suitable for clean and dirty water
• Designed to handle suspended sand and silt
• 50mm (2") discharge outlet
• Automatic external float switch
• Impact-resistant PVC strainer base
• Built-in thermal motor protection
• IP68 protection rating
• 10m electrical cable

Performance

The KA-2.4 is designed for drainage and water transfer applications where durability and solids-in-suspension resistance are important.

Pump performance

• Maximum flow: 240 L/min
• Maximum head: 12m
• Motor power: 400W / 0.4kW
• Outlet: 50mm (2")
• Maximum liquid temperature: 40°C
• Permitted liquid pH: 6.5–8.5

Maximum flow and maximum head occur at different operating points. Actual flow depends on the vertical lift, discharge pipework and friction losses.

The semi-vortex impeller is suited to water containing suspended sand and silt, but the pump should not be used for applications outside the manufacturer's stated operating limits.

FAQs

Can this pump handle dirty water?

Yes. The KA-2.4 is designed for clean and dirty water, including water containing suspended sand and silt. Its semi-vortex impeller provides improved wear resistance for suitable drainage applications.

Is it suitable for construction sites?

Yes, for light construction-site dewatering, including suitable water containing suspended sand and silt. It is not intended for unrestricted heavy-solids or slurry pumping.

Does the pump operate automatically?

Yes. The supplied external float switch starts and stops the pump as the water level changes, provided the float has sufficient clearance to move freely.

Can I use it for irrigation?

Yes. It can be used for suitable water transfer and irrigation applications, provided the required flow and delivery head are within the pump's performance capabilities.

Can it pump water containing stones or large debris?

The pump is designed for water containing suspended sand and silt, but a maximum solids passage size has not been specified. Do not assume it can handle stones or large debris.

Is it suitable for hot water?

The maximum permitted liquid temperature is 40°C.
