Product catalog summary

Declaration of Conformity
Lubi Electricals Limited confirms that the LBS Series Centrifugal Pump and Induction Motor comply with CE directives for low voltage, machinery, and electromagnetic compatibility. Relevant standards include IEC 60335-2-41, IEC 60335-1, EN 809, IEC 61000-6-3, and IEC 61800-3 for pumps, and IEC 60034-1, IEC 60034-5, IEC 60335-1, EN 809, IEC 61000-6-2, and IEC 61000-6-3 for motors.

Product Overview
The LBS series features single-stage bare shaft end-suction pumps designed per ISO 2858. They are suitable for applications such as water supply, pressure boosting, industrial washing, fire protection, cooling systems, and irrigation. The pumps are non-self-priming with axial suction and radial discharge ports, available with gland packing or mechanical shaft seal.

Performance and Construction
The pumps offer a discharge range from 3 to 660 m³/hr and a head range from 4 to 158 meters, with motor ratings from 0.37 to 132 kW. They are dynamically balanced to ISO 1940 standards and mounted on a fabricated steel base frame. The back pull-out design facilitates maintenance without disturbing the volute casing and piping.

Operating Conditions
Designed for non-explosive, clean liquids without solid particles, the pumps can handle liquid temperatures from 0°C to +140°C, depending on the mechanical shaft seal. The ambient temperature should not exceed +45°C for EFF2 motors and +60°C for EFF1 motors. Higher output motors are recommended for installations above 1000 meters or in higher ambient temperatures.

Construction Features
The volute casing is robust, with standard flanges available in PN 16, PN 25, ANSI 125, and ANSI 250. The impellers are closed with a smooth finish, dynamically balanced, and can be trimmed for specific duty points. The pumps are hydrostatically tested for leakage, and the motors are squirrel cage induction types, complying with IEC standards.

Sound/Noise Levels
The motor noise levels comply with ISO 3743, ensuring they do not exceed the maximum sound pressure levels specified.

Motor Specifications and Requirements
