KN Brass - Regenerative Turbine Electric Pumps

Product catalog summary

Specifications:
The document describes regenerative turbine electric pumps designed for welding and cutting applications, specifically for MIG, TIG, and PLASMA cooling units. These pumps are available in brass or polymer and feature high-efficiency motors compliant with IE3 standards, characterized by low starting torque. They are not self-priming and are suitable for clear, non-aggressive liquids without abrasive substances. The operational temperature range for the liquid is -20°C to +90°C, with an ambient temperature limit of +40°C. Compliance with standards EN 60034-1, EN 60034-30, EN 60335-1, and EN 60335-2-41 is ensured.

Procedures:
The pumps can be equipped with either an induction AC motor or a sensorless brushless DC motor. Customization options include special voltages, dual-frequency, and fluid temperatures up to 180°C. Accessories such as heat exchangers, flow switches, and tanks are also available.

Norms and Standards:
Manufactured according to EN 60034-1, EN 60034-30, EN 60335-1, and EN 60335-2-41 standards, these pumps are designed for continuous duty (S1) with a 2-pole motor and insulation class F. The protection class is IP42 for AC motors and IP54 for DC motors.

Recommendations:
The pumps are recommended for applications requiring high pressure with low flow and long life. A magnetic drive execution is advised to minimize leakages and maintenance.

Key Data from Tables and Graphs:
Performance graphs illustrate hydraulic characteristics for water at 20°C at nominal pump speed. The document also provides dimensions and material specifications for different pump models, such as KN37 and KN45, including details on power consumption and construction materials.
