low-noise

The Perfect Partner for Your Servohydraulic Test System Instron®’s 3520 series allows you to configure a Hydraulic Power Unit (HPU) to meet all your testing requirements and site conditions with unsurpassed efficiency and low environmental impact. They are used to provide varying flow rates of hydraulic oil at high pressure and are compatible with the full range of Instron’s Servohydraulic Dynamic and Fatigue Testing Systems. The 3520 Series includes model variants producing 210 bar or 280 bar and flow rates from 27 to 118L/min (7.1 to 31.2 GPM). Benefits Low Noise Levels: Acoustic attenuation system providing noise levels of 58 - 63 dB (A)*. Low Operating and Power Costs: The pressure-compensated variable flow pump configuration ensures operating costs are maintained with test flow demand. Combined with high-efficiency Class 1 motors, power costs are kept to an absolute minimum. *dB (A) is a measurement of the sound pressure level (units Decibel, dB), weighted to suit the normal frequency response of the human ear. It is expressed in free field (open) conditions, and therefore readings may vary within the installed environment.
