® ELIKA Helical Gear Pumps 4th September 2025 also available via LinkedIn Introduction Noise, vibration, and inefficiency remain major challenges in hydraulic system design. Conventional external gear pumps, while robust, often produce excessive acoustic emissions, pressure pulsations, and energy losses that can shorten equipment life, reduce operator comfort, and increase operating costs. The ELIKA® helical gear pump, developed by Marzocchi and distributed by JBJ Techniques, represents a step-change in hydraulic pump technology. By combining a patented helical gear tooth profile with advanced compensation systems, ELIKA® offers unprecedented noise reduction, efficiency, and reliability, delivering a high-performance solution across industries as diverse as power generation, oil & gas, renewables, marine, motorsport, food & beverage, transport, and environmental/materials handling. The Challenge Hydraulic systems are critical to modern industry, but they are not without drawbacks: » Excessive noise leads to operator discomfort, regulatory non-compliance, and mechanical wear. » Pressure ripple and vibration cause instability, cavitation, and reduced system accuracy. » Internal leakage undermines volumetric efficiency, particularly at low speeds and high pressures. » Energy inefficiency drives up running costs and carbon footprint. These challenges demand an engineered solution capable of combining robust hydraulic performance with quiet, efficient operation. The ELIKA® Solution ELIKA® addresses these issues head-on: » Noise Reduction: Up to 15 to 20 dBA lower than conventional gear pumps. » High Pressure Capability: Continuous working pressures up to 300 bar, peaks up to 310 bar. » Broad Displacement Range: From 2.1 cm³/rev to nearly 200 cm³/rev across four series (ELIKA1P, ELIKA2, ELIKA3, ELIKA4). » Efficiency: Volumetric efficiency >90% even under low-speed/high-pressure duty cycles. » Flexibility: Compatible with a wide range of pump families (for example ALP2/GHP2) and configurable in tandem/multiple units. » Reliability: Optimized axial compensation reduces internal leakage and extends service life. Technical Q&A Q1: What sets ELIKA® apart from traditional external gear pumps? A: ELIKA® employs a helical gear tooth profile that ensures continuous engagement, lowering pressure ripple and vibration. Its patented axial compensation system minimizes internal leakage, resulting in higher volumetric efficiency and longer life compared to straight-tooth gear pumps. Q2: How does ELIKA® achieve significant noise reduction? A: By spreading the load across the helical tooth surface, ELIKA® reduces vibration and high-frequency excitation at the source. This translates into noise reductions of up to 20 dBA, a critical advantage in industries such as marine, transport, and food & beverage, where noise control is both a safety and comfort factor.
