The new Martel/Beta high pressure hand pump is a revolutionary portable pneumatic pump that can generate pressures up to 2000 psi (140bar) and vacuum to -14 PSI (-0.9bar) quickly and easily. The MECP2000 uses a unique dual stage pump design where a low pressure, high volume chamber is used to pre-charge a secondary high pressure chamber. This allows the pump to reach high pressure quickly and with a minimal amount of effort. The pump motion stays smooth through the entire stroke. A precise vernier control allows pressure to be fine tuned with high resolution. The vernier chamber provides enough range so it can be used to generate low pressures (200" H20 or 500mbar) with no pumping. Both high and low pressure calibrations can be done with one device.
