* f FLUID POWER DESIGN INTRODUCTION Kappa 35 Compact series is a heavy duty, two-piece construction, cast iron pump. The robust design ensures high performances, reliability and long service life. DISPLACEMENTS From 63,88 cm3/rev (3.90 in3/rev) To 100,08 cm3/rev (6.10 in3/rev) PRESSURE Max. constant operating pressure 260 bar (3770 psi) Max. system pressure (relief valve setting) 275 bar (3988 psi) Max. peak of pressure 290 bar (4205 psi) SPEED Max. 3000 min-1 TYPICAL APPLICATIONS • Building & Construction Machinery • High working pressure • Long service life - High reliability • High...

* f FLUID POWER DESIGN INSTRUCTIONS INSTALLATION PUMP The direction of rotation of single-rotation pumps must be the same as that of the drive shaft. Check that the coupling flange correctly aligns the transmission shaft and the pump shaft. Flexible couplings should be used (never rigid fittings) which will not generate an axial or radial load on the pump shaft. TANK Tank capacity must be sufficient for the system’s operating conditions ( ~ 3 times the amount of oil in circulation) to avoid overheating of the fluid. A heat exchanger should be installed if necessary. The intake and return...

* f FLUID POWER DESIGN MULTIPLE PUMPS KAPPA series pumps can be coupled together in combination. In applications where the input power requirement of each section varies, the section with the greater requirement must be at the drive shaft end, and progressively smaller to the rear. Features and performances are the same as the corresponding single pumps, but pressures must be limited by the transmissible torque of the drive and connecting shafts. To have appropriate data, use the formula below. The maximum rotational speed is that of the lowest rated speed of the single units incorporated....
