◆ Structure : ZCB-700AB bidirectional hydraulic electric pumps are single -phase or three-phase asynchronous motors , reversing switches, high pressure pumps , tanks , tubing and other components. With small size , high pressure , light weight , simple structure , easy to use and so on. Commutation of the pump is a three -way switch M-type manual valve to control double- acting cylinder : mid-range is the dwell position allows the cylinder piston under pressure to stop movement. Left and right two steps are hydraulic output location in a different direction , under the action of the hydraulic piston up or down , to work. ◆ Use: The pump is after many years of engineering experience and technical personnel and research and development of a new type of hydraulic power pumps , dual hydraulic tubing , without spring return , durable. Mainly used for large-tonnage dual tubing hydraulic tools, such as large -tonnage jacks, crimping machine, punching machines. Reduce labor intensity and improve working efficiency. ◆ Features: The pump is designed with high and low two out of oil , fast and efficient. Using pressure safety overload protection device , to avoid overload damage. Meanwhile a pressure gauge, can be observed at any pressure change when working . Tubing connector with PT3 / 8 " teeth . ◆ Weight : 32kg ◆ Packing : wooden box
◆ Technical parameters:
