At a glance:
It applies to grease with penetration not less than 265（25℃,150 g）1/10 mm and grease with viscosity grade greater than N68
suitable for lubrication in -20℃~80℃
The DDRB-N (original ZB)multi-point grease pump applies to the centralized lubrication of multi-line small and medium mechanical equipment with infrequent lubrication, less than 50 lube points, and nominal pressure of 31.5 MPa, supplying grease to the lube points directly or through a single-line distributor. It is especially applies to single equipment for metallurgy, mine, heavy-duty machine, port transportation and construction, etc.The DDRB-N multi-point grease pump consists of grease reservoir, speed reducer, pressure oil plunger pump, motor, etc.
The motor drives the worm speed reducer. The worm shaft drives the eccentric driving wheel to rotate at low speed. The pulling disc of the driving wheel drives the plunger of the pressure oil plunger pump to reciprocate to suck grease. As a result, the grease is discharged from the pump outlets.
