1 NS SRS NS Series ompact Variable ump Unit ompact hydraulic units are widely used as a power source in such machine tool applications as N lathe check opening and closing, tool rotation, machining center spindle raise and lower operations, etc. uring pressure holding, the NS unit enables high machine efficiency that delivers energy savings of approximately % compared to standard Nachi units (in-house comparison), all in a compact, lightweight hydraulic unit. eatures ncreased energy savings Support for using an efficient premium motor provides % energy savings compared to standard unit (in-house comparison while dwelling) ower consumption (kw)... welling (full cut-off) Motor - polarity:. kw - Voltage - frequency: V - z Standard unit NS Series Specifications % down. Setting pressure at (Ma) Space-saving Variable vane pump has integrated motor so installations in compact spaces are easy in a compact and streamlined layout. asy Operation and Maintenance Simple construction and highly reliable pump controls mean excellent maintenance and handling. onserve Resources ydraulic fluid in a low-volume tank helps conserve the world's resources. ompliant with U and S in the US ineup of models use U certified electric motors and comply with the US nergy ndependence and Security ct. igh fficiency for ow eat Output Motor efficiency is high and heat output is low, particularly when the pump is dwelling, to support high accuracy for the parent machine. tem Model No. NS-*-*VO* NS-*-*V* NS-*-*V* ump apacity cm /rev...
