1 Axial piston variable displacement pump type V60N For commercial veicles Open circuit Nominal pressure Maximum pressure p max Geometric displacement V max = 350 bar (5075 psi) = 400 bar (5800 psi) = 90 resp. 110 cm 3 /rev (5.5 resp. 6.6 cu in) 1. General information Tis variable displacement pump wit its rugged construction is designed for direct mounting at te auxiliary drive (P.T.O.) of commercial veicles as well as for standard mounting via a SAE-flange. Wit a max. displacement of 110 cm 3 /rev and a peak pressure of 400 bar it is suited for many applications. Tis is complemented furtermore by te ig self priming rate and te low noise level. Tese features can be best employed wen te variable displacement pump is combined wit te directional spool valves type PSV according to D and te corresponding over-center valves type LHT and LHDV according to D 7918 and D Reversing te rotation direction is very simple and can be done out in te field, wic elps to adapt te pump to existing applications Available versions, main data Order example: V60N R DUN /LSN A00/76 Suction connections, see table 3 page 6 Basic type Table 1: Nominal size Coding Geometric displacement V g Nom. pressure p nom.

Te ousing of te pump sould be primed via te upper case drain port. Te case drain line must be routed in suc a way tat running empty is prevented. Te pressure limiting valve sould be set to 50 bar or lower for initial operation and te first few minutes of regular service.
