Type WRZ112A Wall-mounted Automatic Double-line Grease Central Lubricating Apparatus and System and Type WRZ122B Wall-mounted Automatic Step-by-step Grease Central Lubricating Apparatus and System are renovated practical products jointly developed by China Baosteel Inc.and our plant.

●Appearance and dimensions

●Features:

1.In this apparatus,lubricating system and controlelement are put into one trunk.The standard structural designcompact reasonable layout,fine material and good sealing quality enable this machine to work well in high altitude,in the open air,in dusty places and other harsh working environment. 2.This apparatus is small,complete in function and excellent in capacity.We will finish assembling whin offer.It should be mounted on the wall.The machine works whin oil route and electric cable are connected to it.It is convenient to install and use. 3.This apparatus is very practical,especially suitable for singledouble line grease central lubricating system.The connection of the bidriectional or step-by-step dispenser and tubing required by the equipments to this machine makes an automatic grease central lubricating system.The modification of the manual grease lubricating system at hand can be easily achieved by replacing the manual bubricating system pump by this apparatus.Because the lubricating systems,especially the high-altitude crane lubricating system,can automatically p\operate following certain control procedured,it not only reduces the workload and trouble of the supervisous and workers but also increases security. 4.There are telecontrol poerating keys and an observation window which can be opened on the front door of the steel trunk of this apparatus..There is also a window on the lower aprt of the door from which the telecontrol indicator light,lubricating pump and commutator valve can be observed without opening the door. All the advantages of this apparatus have been constantly recognized .In recent years,this apparatus has been applied and promoed widely in the machinery lubrication system of crane cars in workshops,freight yards nad ports,stackers,reclaimers,ship loaders and unloaders and other small and medium size grease lubricating system.
