This high-pressure pump generates pressures of up to 700 bar with ease, with fine control for precise adjustment. It is perfect for testing manometers and pressure transmitters. The pump must be filled with 100 cm3 of hydraulic oil or water and can therefore fill up even relatively large dead volumes. An additional manometer (not supplied) is needed for reference measurement of the configured pressure. KELLER recommends manometers in the LEX1 series with a suitable pressure range.
