Centralized Lubrication Systems, Hydraulics and Pneumatics

SHOWA PROPER UNIT (METER UNIT)

Flow Proper Units are to be installed within a resistant type system utilizing the intermittent / cyclic distribution method. Flow Proper Units enable delivery of oil at a required flow rate and can be attached to Distribution Blocks or individual lubrication points.

Six types of connector combinations are available, each with a selection of 7 oil flow rates. As classification number increases a step, the flow rate doubles, allowing flow manipulation to the desired effect.

These units are to be used in conjunction with accumulative pressure type pumps. Please do not use the Flow Proper Unit with volumetric type pumps, grease pumps or LA type manual pumps.
