Norco Push-Button Pump with an air/hydraulic design provides 3,250 PSI of pressure with an air pressure range of 60-120 PSI. This pump, made in the USA, is for industrial and construction jobs that require single-acting rams with a capacity of up to 55 tons, providing the added convenience of an air motor to reduce pumping time and effort. This model pump features a manually-activated push button for pumping and a lever for release of the load, and the pump operates in all positions for increased versatility in use and mounting. Designed to utilize exhaust air to help power the pump, this pump requires only 80 PSI of air pressure to develop the 3,250 PSI of hydraulic pressure and includes a steel reservoir body. Designed with durable lightweight, corrosion-resistant plastics, the pump includes an air exhaust muffler for quieter operation, as well as air and oil inlet filters to reduce the risk of damage from contamination. Also designed for use with a single-acting cylinder, this pump includes an internal pressure relief valve for overload protection. Norco charges a limited access fee for shipments to military bases, schools, churchs, and all other gated areas, as well as charging a substantial fee for re-delivery of order, lift gate use, and residential delivery. Also, local sales taxes will be applied to ALL Norco orders shipped to California.
