The BL 656 ultra-high hydraulic pressure calibration pump is a hand operated pressure pump designed to generate pressure up to 250MPa (2500 bar). With the special screw press technology, the high pressure can be easily generated, increased and decreased smoothly. A specially designed shut-off valve makes the pressure stability as high as possible during calibration. Without non-returning valve that is usually used in “trouble-maker” hand pump, the BL656 has minimal maintenance required. The BL 656 is an ideal comparison test pump for calibrating ultra-high pressure measuring instruments against test gauges, indicators or transducers in the laboratory.
