Hygienic Design and Material Integrity

The Alfa Laval GM centrifugal pump is constructed using W. 1.4404 (AISI 316L) stainless steel for all product-wetted steel parts. This ensures maximum corrosion resistance, making it an ideal choice for the transfer of acidic products and use in aggressive environments. The standard GM model features a glass fibre-reinforced nylon impeller and a robust pump casing, while the GM-A variant utilizes a 316L stainless steel impeller and yoke for increased durability and a wider temperature range.

Small Centrifugal Pump Performance for Low Capacities

Many industrial pumps are oversized for specialized low-flow tasks, leading to energy waste and mechanical strain. The GM series solves this problem by handling capacities up to 15 m³/h and differential pressures up to 2 bar at 50Hz. By selecting a pump specifically sized for low volumes, operators can maintain consistent process flow without the complexity of larger equipment. The inclusion of a single mechanical seal simplifies maintenance while ensuring leak-free operation for sensitive hygienic applications.

Flexible Configurations for Process Integration

To meet specific system requirements, these pumps offer various customization options. The impeller diameter can be reduced to match precise flow curves, and multiple connection standards such as Clamp ISO 2037, Union SMS, and Union DIN ISO are available. This flexibility allows for seamless integration into existing pipework, ensuring that the pump meets both the hydraulic and physical requirements of your facility.

FAQ

Euroflow serves customers across southern and central Germany — covering postal code areas 66–99 and 07–08, spanning Baden-Württemberg, Bavaria, Saarland, Rhineland-Palatinate, Hesse, Thuringia, and Saxony. As an Alfa Laval Master Distributor for tank manufacturers, plant engineers, system suppliers, and end customers, we provide expert support in selecting and designing systems for viscous product handling and cleaning applications.

The primary difference lies in the material of the impeller and housing components. The GM uses a nylon impeller and is rated for temperatures up to 80°C, while the GM-A uses a 316L stainless steel impeller and can handle temperatures up to 140°C. Both models function as a reliable hygienic centrifugal pump for low-flow duties.

Yes, all product-wetted steel parts are manufactured from AISI 316L stainless steel, allowing for the safe transfer of acidic products. This makes the pump highly resistant to corrosion in aggressive environments typically found in food and dairy processing.

To ensure the correct configuration, you must provide the pump type, desired connections, and motor voltage. Additionally, technical details such as flow rate, pressure, temperature, and the density and viscosity of your product are required to select the optimal impeller and seal options.
