Whether you regularly perform pneumatic (air) pressure adjustments or hydraulic (oil and water) pressure modifications, you can rely on our handheld and hand-operated pressure pumps. We optimize our pneumatic pumps for ambient temperature resistance, pressure consistency, and stability in producing compatible pressures. Instead of using check valves, our handheld pressure pumps use isothermal bellows chambers. This mechanism maintains temperature consistency, which improves pressure integrity. Additel's hand-operated pressure pumps utilize patented screw press functionality to achieve high levels of pressure without strenuous manual effort. Our high-end hydraulic pumps are capable of generating pressure up to 60,000 psi. Shop our pneumatic and hydraulic calibration pumps today!
