DAB.K - single impeller pumps

The DAB.K series includes single-stage, horizontal centrifugal pumps with cast iron or polymer impellers, designed for clean, non-aggressive, non-viscous liquids. These pumps are suitable for heating systems, circulation, and industrial applications where medium to high flow rates and head are required. They operate within a temperature range of -10°C to +50°C for most models, with select variants handling up to +110°C.

Available in various flow and head capacities, these pumps are engineered for durability and efficiency in environments where liquid properties are similar to water.

How to choose

• Match the pump’s flow rate (1.8–96 m³/h) and head (up to 62 m) to the system’s hydraulic requirements.
• Select the appropriate impeller material (polymer A/B or cast iron) based on the liquid’s chemical compatibility and abrasion resistance.
• Ensure the motor type (single-phase or three-phase) aligns with the electrical supply and consider additional overload protection for three-phase variants.
• Verify the pump’s temperature range matches the operating conditions of the liquid being pumped.
• Confirm the connection type and size (threaded or flanged) for compatibility with the system piping.

Frequently asked questions

What is the maximum operating temperature for DAB.K models?
Most models operate between -10°C and +50°C, while select variants can handle up to +110°C.

Can DAB.K pumps handle aggressive or viscous liquids?
No, these pumps are designed for clean, non-aggressive, non-viscous liquids similar to water.

What motor protection is included?
Single-phase motors include built-in thermal protection and a capacitor; three-phase motors require external overload protection.
