The Shore Western WhisperPak® Series are acoustically treated laboratory quality hydraulic power units designed to meet
the exacting requirements of servo-hydraulic control systems. These power units utilise quality components
and micro-clean filtration to provide trouble-free long life with minimum maintenance. A complete system
of interlocks and controls allow failsafe unattended continuous operation. Low noise level and leak-free
components allow use directly in the laboratory next to the test equipment. Typical applications include:
* Laboratory and Test Lab HPS
* Large flow central HPS systems
* Used where sound attenuation is required
The low noise level is achieved by use of inherently quiet components operated as a submerged pump/motor unit(s) inside the
enclosed hydraulic oil tank. Output is filtered by pulsation dampers and connected through low velocity flexible
hoses to a piping interface manifold. The pumping assembly is mounted with isolators in a completely sealed,
acoustically treated enclosure to eliminate airborne noise and prevent heat discharge into the surrounding
environment. All possible connections, including components, utilize o-ring fittings or welded joints to
eliminate external oil leaks. Units range in size from 7 gpm to 180 gpm. Standard units are wired for 380/460
VAC, 3 phase, 50/60 Hz. Other voltages and frequencies available.
