Patent Images
1. A portable lubricant filtration system including:
- a supporting frame comprising a frame carried by wheels;
a lubricant pump having an inlet for coupling to and receiving lubricant from an external source;
a lubricant transport manifold unit, said manifold unit comprising a lubricant inlet coupled to said pump, and a filtered lubricant outlet for coupling to and transmitting filtered lubricant back to said external source;
a first replaceable lubricant filter element, said first filter element fluidically communicating with said lubricant inlet and said filtered lubricant outlet and carried by said manifold unit;
a second replaceable lubricant filter element, said second filter element fluidically connected in series between said first replaceable lubricant element and said filtered lubricant outlet and carried by said manifold unit;
at least one pressure gauge for measuring pressure differential between said first and second filter elements;
a bypass line included in said manifold, having a needle valve therein and being capable of placing said lubricant inlet and said filtered lubricant outlet in fluid communication via manipulation of said needle valve;
at least one lubricant sampling port, said at least one lubrication sampling port being in fluid communication with at least one of said first and second filter elements; and
a check valve positioned between said second filter element and said filtered lubricant outlet, said check valve positioned to control direction of lubricant flow.
