ASI Hydraulics’ line of 20 HP Submersible Power Units far exceeds anything available in the fluid power industry today. It’s unique design and carefully chosen components make it a staple in on-site machining, line boring, shovel and drag line repair and portable boring. The motor and pump are strategically placed within the hydraulic fluid reservoir to both aid in cooling and noise suppression. This innovative design alone has solved many of the issues fluid power engineers have long battled. Using this concept, industry professionals have come to ASI Hydraulics for help with their applications.
