Dropsa’s nano-Progressive Replaceable (nPr)


RigidLockdividers are the ideal solution for oil and grease lubrication applications that require
small and accurately dispensed quantity of lubricant in a compact and solid footprint. Thanks to a Description

patented RigidLock novel interlocking mechanism between the elements it has the rigidity of a mono-block divider but the exibility of a modular segmented unit.

The nPr, uses the progressive movement of pistons to allow precise quantities of lubricant to be accurately dispensed to multiple points.

The lubrication cycle can be controlled by a single sensor including the Dropsa solid state Ultra- sensor product.

nPr uses an innovative rail & lock concept to allow the element to be replaced or re-organized without the need to completely dismantle the assembly. This is an industry rst for segmented progressive dividers allowing quick easy modi cation or replacement of an assembly element without the cost of a separate base porting module.

The compactness makes them particularly suitable for use in con ned spaces.
These metering elements may be used in a variety of system con gurations and have di erent working con gurations that make them exible for use in multiple applications.
