Gear Pumps 1P R Series www.jbj.co.uk/gear-pumps.html #DriveLineHarmony Their operating concept is the same as single rotation pumps. What changes is that bi-rotational pumps can rotate both clockwise and counterclockwise thanks to their perfectly symmetrical machining on the internal components. Please contact jbj Techniques Limited technical office, tel +44 (0)1737 767493 or email: info@jbj.co.uk if system operating conditions differ from the values indicated in the product tables. Some models have the external drain positioned on the flange or on the cover; connection pipes to the system tank should never be clogged or show reduced cross-section, otherwise pressure values might exceed 6 bar. As described at the beginning of the single rotation pump section, also bi-rotational models are rotary positive-displacement pumps with external gears. The reversible 1Ppump is capable of handling pressurized inflow. 27
