pressure relief valve

You can get the pumps with an internal pressure relief valve (RF1, RF2, RF3), permanently set to 5, 10 or 15 bar. An externally adjustable pressure relief valve (RP) for pressures of up to 25 bar is also available. The RF version is available with all suction variants, the RP version only with the standard suction flange.
