Wet rotor circulation pump type ALPHA1L 25-60 130 1x230V 50Hz 6H ALPHA 1L series 99160583

Circulation pump ALPHA1 L 25-60 is an advanced solution for efficient water circulation in heating systems. Designed for both domestic and commercial installations, it combines high performance with ease of use. It utilizes a permanent magnet motor, which translates to low energy consumption and quiet operation. The pump is versatile – it works perfectly in radiator installations, underfloor heating, and domestic hot water systems.

Construction and application

ALPHA1 L is a non-clogging pump, which means there is no risk of the impeller being blocked by sediment. The compact design makes installation easy even in tight spaces. The ability to control via PWM (pulse width modulation) signal allows for precise adjustment of the pump's performance to the current needs of the heating system. Therefore, regardless of whether the installation requires constant flow or dynamic regulation, ALPHA1 L ensures optimal operation. The pump is particularly recommended as a replacement for older Grundfos UPS series 100 models.

Advantages and benefits

• High energy efficiency: EEI below 0.20 guarantees minimal power consumption and reduced operating costs.
• Versatility: Possibility of use in various types of heating installations – from traditional radiators to modern underfloor heating systems.
• Easy operation: Intuitive control panel allows for quick setting of the pump operating mode – constant speed or proportional regulation to the heat demand.
• Reliability: Solid construction with high-quality materials ensures long life and trouble-free operation. The cast iron GG 15 (GJL-150) body guarantees resistance to corrosion and mechanical damage.
• Simple installation and maintenance: Compact dimensions and easy access to control elements facilitate installation and servicing of the pump. Additionally, the ability to manually unblock the impeller in case of blockage greatly simplifies the maintenance process.
• Quiet operation: Low noise level below 43 dB ensures comfortable use even in residential premises.
• Wide temperature range: The pump can operate in a liquid temperature range of 2°C to 95°C and an ambient temperature range of 0°C to 55°C, making it suitable for various working conditions.

The ALPHA1 L pump is an investment in comfort and energy savings that will be appreciated by both professional installers and end users. Its reliability and ease of use make it the ideal choice for any heating system requiring efficient water circulation.
