The hydraulic cylinder is the primary component of any hydraulic lift system. Pentalift’s exclusive PentaFlow cylinder design ensures long cylinder life, reduces maintenance, and eliminates oil spills. The PentaFlow cylinder is completely sealed from the surrounding atmosphere and all components are continuously bathed in fresh oil. Contamination and deterioration of the cylinder cannot occur. When the cylinder reaches full extension, the bypass valve opens and allows oil to flow through the piston to the rod side of the cylinder, out the port, and back to the reservoir. This prevents the cylinder from dead ending and building high stresses in the cylinder, equipment structure, and hydraulic system. Air in the cylinder is automatically ejected through the bypass valve. The need for manual bleeding which often results in oil spills is eliminated.
