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 technical office, tel: +44 (0)1737 767493 or email: info@jbj.co.uk. if systemoperating conditions differ from the values indicated in the product tables. The external draining is located on the cover and it must be connected always to the tank; connection pipes to the system tank should never be clogged or show reduced cross-section, otherwise pressure values might exceed 6 bar. The reversible pumps can handle pressurized inflow. The pressures P1, P2, p3 of the reversible pumps of the GHP series must be reduced of approx 15%with respect to the pressures indicated on the performing charts relevant to themono-directional pumps. #DriveLineHarmony
