Mobile pumping unit 430-1

industrialin-line

These pneumatic hydraulic pressure pumps are suitable for application in simple clamping systems for actuating single-acting or double-acting clamping elements. The pressure pumps convert a pneumatic inlet pressure into a hydraulic operating pressure. Pressure adjustment and compressed air treatment are done in an external maintenance unit. The single-acting pressure pump clamps or unclamps the connected clamping elements by manual operation of the pedal. The pressure pump supplies hydraulic oil until the desired operating pressure is reached. The integrated check valve keeps the oil pressure constantly. In cases of pressure loss e.g. through leakage, automatic replenishment is not given. The pressure pump for double-acting clamping elements allows constant pressurization. Clamping and unclamping of the clamping elements is done by using the control lever of the 4/3 directional valve. depending on the position of the directional valve, the clamping elements will extend or retract by pressing the pedal on "PUMP". The pedal must be pressed until the clamping elements have reached their end position and the desired oil pressure is built up. The pedal can be fixed in position by the pedal lock. After that, clamping and unclamping of the clamping elements can de done by using the control lever of the 4/3 directional valve. When the pedal is fixed, the double-acting pressure pump can compensate a low pressure loss automatically. Special features: integrated pressure control valve up to 500 bar low weight, easy to transport suitable for mobile use suitable for application in explosive hazardous areas
