Elika® helical gear pumps
Elika® helical gear pumps
The Elika series by Marzocchi consists of helical gear pumps designed to reduce noise and pulsation, achieving up to 20 dBA noise reduction compared to conventional gear pumps. Available in groups 2, 3, 4, and multiple configurations, these pumps are ideal for applications requiring low noise levels.
Elika pumps feature a patented helical gear profile that minimizes pressure oscillations and vibrations, reducing noise transmission and internal leakage. This enhances volumetric and mechanical efficiency, making them suitable for low-speed, high-pressure operations.
These pumps offer a wide range of rotational speeds, working pressures, and viscosity bands. An axial compensation system balances axial forces, ensuring optimal performance. They are available in both clockwise and counter-clockwise rotations.
Guidelines for installation, cleaning, and filtering are provided to ensure optimal performance and longevity. The pumps are interchangeable with standard gear pumps like the ALP2 and GHP2 series.
Elika pumps demonstrate lower noise levels and higher efficiency compared to conventional gear pumps, maintaining high volumetric and mechanical efficiency across various conditions.
The Elika series represents a significant advancement in gear pump technology, offering low noise, high efficiency, and versatility for a wide range of industrial applications.
Patented by Marzocchi Pompe, the Elika gear pump eliminates air encapsulation, reducing noise and vibrations. It minimizes internal leakage, enhancing volumetric efficiency, and is suitable for low-speed, high-pressure operations.
Elika pumps outperform other volumetric pumps in rotation speed, work pressure, and viscosity range, reducing noise by an average of 15 dBA compared to conventional pumps. They are interchangeable with standard gear pumps.
Featuring a helical gear design, Elika pumps ensure continuous flow with reduced noise frequencies. An axial compensation system reduces internal leakage and ensures proper lubrication.
Proper installation and maintenance are crucial. Use mineral oil-based hydraulic fluids and maintain fluid cleanliness to prevent damage.
Ensure proper alignment of pump and motor shafts, protect the drive shaft seal, and monitor fluid and component temperatures. Avoid starting the system under load at low temperatures.
The document emphasizes using mineral oil-based hydraulic fluids with specific properties and compliance with DIN 51525 and VDMA 24317 standards. Fluid temperature should range between 10°C and 80°C.
