Pump controllers / Intermediate plates, see page 3 Shaft design/Housing design: 1 2 3 Seals: N V Description of the controllers LSNR Load-Sensing controller with integrated pressure limitation NR Pressure controller, adjustable directly at the pump. The Pressure controller automatically maintains a constant system pressure independant of the required flow. Therefore it is suited for constant pressure systems, where differing flow is required or as efficient pressure limitation of the hydraulic system Intermediate plates Intermediate plate only in combination with controllers LSNR or NR /ZL Intermediate plate with power controller (torque limitation) Product ”Pressure x Displacement” = constant Adjustment range: 25...100% of max. drive torque /ZW Angled intermediate plate (45°) mandatory for mounting controllers at pumps with housing design -2, -3 2 = Ports conforming ISO 228/1 (BSPP) = Ports conforming SAE J 514 = Standard, suction port and pressure outlet axial = Thru-shaft, suction port and pressure outlet radial = Standard, suction port and pressure outlet radial = NBR (Nitrile rubber) - Standard = FKM
