Technical Data

Central lubrication pump Type ZPU08 Type ZPU14 Type ZPU24

Lubricant output 8 dm³h‾¹ 14 dm³h‾¹ 24 dm³h‾¹Operating pressureReservoir capacityLubricant filterLubricants

pmax = 400 bar40 or 100 dm³

filtering surface 5.1 cm², filter capacity 280 µmgrease up to NLGI class 3 acc. DIN 51818

NOTE: For motors with 60 Hz the speed and thus the lubricant output will be increased by 20%. In the case of ”hard” greases and low temperatures the actual lubricant output may be below the theoretically calculated one.
