1600 3000 4000 bar hand pumps – very high pressure hydraulic hand pumps produced in light aluminum alloy of aeronautical derivation to reduce as much as possible the weight. Available in 3 versions with maximum operating pressure: 1600 bar / 23000 psi – Double stage high speed 3000 bar / 43000 psi – Double stage high speeed 4000 bar / 58000 psi – Single stage Equipped with an ergonomic bypass hand wheel in techno polymer for controlled pressure relief, with integrated pressure gauge connection that allows direct mounting of the measuring instrument with 45 ° inclination for a correct reading and lever locking system for easy and better portability. Oil filler cap with integrated breather. Sturdy feet with holes for attachment to machinery or structures. Pressure safety valve integrated in the pump body for maximum operator safety. Design studied to have high performances maintaining an optimal effort on the lever, a reduced weight and an excellent ergonomics. Robust hand pumps – heavy duty – with long maintenance intervals. Surface treatments to guarantee total reliability in the most difficult environments and maximum durability. Tank capacity from 1,6 to 2 liters. Possibility of mounting manometric sockets, various types of quick couplings, high pressure flexible hoses. For a more accurate reading, the digital pressure gauge supplied with quick couplers is also available. The hand pump can be calibrated to different pressures upon customer request. Hydraulic mineral oil operating fluid, models available on request with different fluids such as: water, glycol, glycerin, phosphoric esters. Custom made versions available for extreme operating temperatures. Sectors of use: steel mills, energy, industry, infrastructure, engineering and testing, mining, ship building, offshore, oil & gas, transport and heavy lifting. Possibility to design and produce special 1600 3000 4000 bar hand pumps on request, with flow rates, performance and dedicated features.
