The pressure switch opens and closes electrical contacts at a preset pressure. When the set pressure is reached, an electrical signal starts or ends the next work process. The pressure switch type DG comes in mechanical and electronic types. The pressure can be set up to a maximum of 70 MPa. The setting is done using a push button, setting button, adjustment screw, or adjustment ring. There are also types of pressure switches that have two switching points for two different pressures.

This is a hydraulic pump driven by compressed air (0.2 to 0.6 MPa). The output is equivalent to 1.1 to 1.5 kW, and there are 16 types of discharge pressures ranging from 9 to 150 MPa. It is optimal as a hydraulic source in areas with explosion hazards. Additionally, it can drive portable hydraulic equipment used as emergency equipment by utilizing compressed air cylinders. The structure is a double-acting plunger pump that boosts pressure based on the area ratio of the piston on the pneumatic side to that on the hydraulic side. The automatic reciprocating motion of the piston is achieved by the pneumatic control valves at both ends of the stroke sending a reversal signal, allowing for continuous discharge. When the hydraulic pressure reaches the maximum operating pressure, the pump stops, and air consumption drops to zero; when the hydraulic pressure decreases, it automatically restarts to maintain the maximum pressure. It consumes little air and can omit components such as relief valves, unload valves, and pressure-holding circuits in the hydraulic system, making it economical. It can be combined with a pneumatic-driven seat valve to form a standard hydraulic unit.

Is your hydraulic pump still running even when it's not in use? There is a reason for that. With the HAWE method, you can stop the pump when it's not needed. This is because there is no issue with stopping the pump. We propose an energy-saving system that uses hydraulic power only when necessary. This is a compact and lightweight hydraulic package that integrates a motor-pump unit within a casing that also serves as a hydraulic oil tank. It constructs a pump intermittent operation circuit that maintains pressure for long periods using only valves. Compared to continuous operation methods, it has a proven track record of reducing electricity consumption by up to 91%. It demonstrates significant effectiveness in reducing lifecycle costs related to energy, hydraulic oil, piping, and installation space.

The single-acting type draws in oil when the lever is moved in one direction and discharges it when moved in the opposite direction. The double-acting type performs both suction and discharge simultaneously with each reciprocating motion of the lever. There are open and closed types of operating mechanisms (lever mechanisms). The closed type lever mechanism is located inside the case (suction chamber) and is circulated with operating oil, so it does not require maintenance. The open type lever mechanism is located on the outside, so timely maintenance (cleaning and lubrication) is necessary.
