Grundfos ALPHA1 L 32-60 180 Circulating Pump

The Grundfos ALPHA1 L 32-60 180 circulator pump, reference 99160590, is a high-efficiency solution designed for heating systems in domestic, commercial, and industrial applications. This state-of-the-art pump is equipped with a permanent magnet motor (ECM technology), which optimises energy consumption and ensures reliable performance. The Grundfos ALPHA1 L is suitable for both new installations and as a replacement in existing heating systems.

Adaptable control modes for greater efficiency:

The ALPHA1 L 32-60 180 pump offers three control modes that allow its operation to be adapted according to the type of heating system:

1. Radiator heating mode: optimised for traditional heating systems with radiators, ensuring adequate flow for even heat distribution.
2. Underfloor heating mode: adjusts the water flow to optimise efficiency in underfloor heating systems, ensuring a consistent temperature across the surface.
3. Constant curve/speed mode: ideal for applications that require constant flow and pressure control, providing precise and controlled performance.

Additionally, the pump can be controlled via a PWM signal (pulse width modulation), allowing seamless integration into advanced heating systems that use this technology to optimise energy consumption and pump control.

High energy efficiency and ErP Directive compliance:

The ALPHA1 L 32-60 180 is a high-energy efficiency circulator pump that complies with the ErP Directive. Its energy efficiency index (EEI) of 0.20 ensures optimised energy consumption, making it an environmentally friendly and economical option in operation. The pump has a minimum input power of just 4 W and a maximum power of 45 W, ensuring low consumption even in high-demand situations.

Thanks to its permanent magnet motor, the pump maintains consistent performance with optimised energy consumption, contributing to significant savings in operating costs over time.

High-quality materials for a long service life:

The Grundfos ALPHA1 L pump is designed with durable materials that ensure reliable performance in various operating conditions. The pump body is made of cast iron (EN 1561 EN-GJL-150), a durable material that offers corrosion protection and a long service life. The impeller is made of composite (PES+30% GF), a lightweight and corrosion-resistant material that ensures efficient and prolonged operation.

The pump includes a ceramic shaft and radial bearings that, together with carbon thrust bearings, provide exceptional wear resistance, ensuring a long service life without frequent maintenance. The pump's wet rotor design allows bearings to be lubricated with the pumped liquid, eliminating the need for additional lubrication and reducing maintenance requirements.

Compact design and easy installation:

The compact design of the ALPHA1 L 32-60 180, with a port-to-port length of 180 mm, facilitates its installation in a wide variety of heating systems. Its adjustable and flexible connector, along with two cable entry positions, allows for quick and efficient installation, saving time and effort during installation or replacement.

The integrated control panel allows for easy selection of the appropriate operating mode for each heating system, and the pump is self-venting, ensuring a straightforward start-up and trouble-free operation from the outset.

Exceptional hydraulic performance:

With a nominal flow rate of 1.94 m³/h and a nominal head of 3.28 m, the Grundfos ALPHA1 L 32-60 180 provides consistent and efficient performance across a wide range of heating applications. The pump is designed to operate with a liquid temperature range of 2°C to 95°C, making it suitable for heating applications in various climatic conditions.

Additionally, the pump is capable of withstanding a maximum working pressure of 10 bar, making it a reliable option for heating systems operating at higher pressures. Its net weight of 2.19 kg and IPX4D protection rating ensure that the pump is lightweight and robust, facilitating handling and installation in compact or hard-to-reach spaces.
