Piston Pumps

Jacktech Hydraulics, an ISO 9001: 2000 certified company, offers HA Series Piston Pumps. These variable displacement piston pumps have high efficiency, lower noise and accomplished energy-saving characteristics and hence are widely used in plastic injection machinery, pressure founding machinery, tools machinery, chemical and light industry field and so on. The pumps has two kinds of controls, which are pressure compensator type (“01” type) and proportional electro-hydraulic load sensing type (“04” type). “01” Pressure compensator type: when the system pressure increases and comes close to the preset cut-off pressure, the pump flow decrease automatically while maintaining the set pressure as it is. “04” Proportional electro-hydraulic load sensing type: This is an energy-saving type control which regulates the pump flow and load pressure to be at absolute minimum necessary level to operate the actuator. Pump flow rate and cut-off pressure are controlled proportional to the input current to the control device on the pump and the input current is regulated by the specific amplifier.
