VPB(G)( M ) Series

The VPB block metering device, which belongs to the progressive metering device range, is available in the designs VPBM (metric threaded connectors) and VPBG (inch threaded connectors). VPBM and VPBG block metering devices are set to a non-adjustable nominal volume per outlet and cycle of 0.20 cm³. The volumetric flow fed via a tube is forcibly distributed in a predetermined ratio to the outlets, i.e. to the lubrication points or downstream progressive metering devices. Pistons aligned in series meter the lubricant for two opposite outlets each and control the function of the neighboring piston. This way, the function of the block metering device can be checked by monitoring any piston by means of a cycle indicator or piston detector. Attachable check valves offer high functional reliability (at high or differing back pressures such as in grease systems). They also provide accurate metering and safe blocking behavior, even for internal and external consolidation of lubricant outlets. Block metering devices distribute a quantity of lubricant delivered by a pump to multiple outlets at the same volumetric ratio. Different output quantities within a progressive metering device are achieved by consolidating two or more outlets. For grease systems with a main metering device and secondary metering device, check valves must be used on the metering device outlets of the main metering device. Opposite outlets can be consolidated by removing a blind screw. Additionally, optional crossporting bars can be attached to consolidate neighboring outlets.
