1 eed Pumps ZP / MZP Symbol General The feed pump from the ZP series is a vane pump for the low-pressure range with constant flow rate. Product eatures l irect drive pump no bell housing or coupling required l Standard with internal pressure limitation valve l Optional with flange-mounted motor l Small construction lengths pplication ield l ilter circuits l ooling circuits l Lubrication technology l Pump transfer units Operation ata Operating pressure max. 0 bar Pressure at the suction port l max bar suction underpressure l max. 0.5 bar overpressure Medium Mineral oil to IN 554 Part and Part Permissible contamination NS Temperature of medium -0 to +80 for mineral oil Viscosity See characteristic curves mbient temperature -0 to +40 Mounting position No restrictions RPM l min. rpm l max.,000 rpm irection of rotation right-turning (view of motor fan wheel) rive (only MZP) rive type: electric motor urrent type: three-phase current or power and voltage see model code Protection class: IP 55 Insulation class: Volumetric efficiency >90% (at υ = 40 mm²/s) Weights ZP-:.4 kg ZP-:.9 kg ZP-: 9.6 kg MZP-/ kw 6.0 kg MZP-/ kw 7.4 kg MZP-/ kw.5 kg MZP-/..50 kw 9.5 kg MZP-/.0.0 kw.5 kg MZP-/ kw 9.5 kg Noise levels ccm/rev bar 6 bar Size Size Size Test fluid: ISO VG46 at 40 (40 mm²/s) The noise level values serve as guidelines, as room acoustics, connections, viscosity and reflection affect the level of noise / 08.6
