Low Noise, Internal Gear Pump GA and GPA Series Operating Data 4 www.jbj.co.uk/gp-gpa-series-internal-gear-pumps.html Internal coupling load* = (p v ) + (p v ) + ( p v ) 2 2 3 3 4 4 *According to number of pump sections and maximum hydraulic load. Frame Size Check Shaft Load Internal Coupling Load 3 3 G(P)A1 < 1.32 x 10 < 0.88 x 10 3 3 G(P)A2 < 5.2 x 10 < 3.5 x 10 3 3 G(P)A3 < 19.1 x 10 < 13.0 x 10 If axial loading is envisaged or a quadruple pump is required, consult jbj Techniques technical office, telephone: +44 (0)1737 767493 or email: info@jbj.co.uk For indirect drives use only pumps fitted with the heavy duty bearing option; see ‘Model Code’ section. Check drive shaft torque limits as for direct drives above and that transverse and axial loads to not exceed the following limits: Maximum Maximum Maximum Frame Transverse Transverse Axial Size Force Moment Force G(P)A1 440N 15.8Nm 300N G(P)A2 820N 41.0Nm 600N G(P)A3 1600N 102.4Nm 1000N
