The 50 series power units are self contained high low systems. Using either a 10-5 or 10-6 series pump and a 3 gallon pressurized reservoir the unit will provide low pressure high flow oil for rapid initial actuation (cylinder extension). The unit senses increased back pressure and automatically starts the pump that will bring fluid pressure to required level. The pump will stall and hold at selected pressure until operation is completed.
The 50 series units were designed to save operating and maintenance costs which combined with the SC pumps ability to hold pressure and not require any energy, all add up to an economical and environmentally friendly solution for hydraulic power.
