Veljan Silent Vane Pumps are specifically engineered to address the critical need for noise reduction in modern industrial and mobile environments. By utilizing large-size cartridge displacements and an optimized internal geometry, these pumps achieve exceptionally low noise levels that are well within stringent industry limits. The uni-directional cartridge design further enhances this quiet operation compared to standard bi-directional units, making them the ideal choice for indoor industrial applications, precision machinery, and environments where operator comfort and acoustic safety are high priorities.

Despite their focus on acoustics, these silent pumps do not compromise on power, delivering a high-pressure capability of up to 4650 psi (320 bar). With a typical volumetric and mechanical efficiency of 94%, they minimize heat generation and energy consumption while maintaining high productivity under load. The inclusion of double-lip vanes ensures superior resistance to particle contamination, while the dry-lubricant-coated cam rings facilitate excellent cold-start capabilities. This balance of silent operation and rugged efficiency allows for stable performance across a wide speed range from 400 to 3600 rpm.
