A technological leap In oil wiper rings brings increased oil savings and reliability because performance counts

New problems with increasing demands: It is time for a new oil wiper The OFD ring (Oil Film Dynamic) addresses previously unknown weaknesses of conventional oil wipers and ensures optimal wiping performance and reliability on high-speed compressors. However, conventional designs have To date, the lack of efficiency of decisive disadvantages: oil wiper rings on reciprocating Massive oil losses due to poor wiping performance compressors has not received a lot of attention. However the trend towards Wear of the piston rod and wiper rings compression at high speeds is forcing Short service life,...

A revolutionary solution: Users confirm performance "There was "zero' leakage on the installed OFD wiper packings. They were installed two months ago and the OFD's have worked fantastic." Satisfied customer, natural gas industry "The best invention since sliced bread." Satisfied customer, oil industry "We are very happy with the spare parts and achieved 40 percent less oil consumption." Satisfied customer, chemical industry Application in a gas storage plant: Four installations with reciprocating compressors are operated unmanned by remote control. Initially, the OFD ring was installed on one...

New working principle, optimal oil wiping action HOERBIGER resolves the problems found in industry-standard solutions with a technological leap in oil wiper rings. The new solution – Oil Film Dynamics from a working principle that has not been used before in this field. This is achieved by using a special sealing ring shape and the use of polymers. Unlike current solutions, the OFD wiper ring makes the most of the benefits of the elasto-hydrodynamic effect: this refers to how the pressure in the lubrication gap between the elastic sealing ring and piston rod brings about the deformation of the...

The design of the OFD wiper ring enables outstanding performance The OFD oil wiping solution consists of a straight-cut insert ring (1) which is enclosed by a straight-cut L-shaped cover ring (2). An axially mounted spring plate (3) prevents lateral movement of the rings. They are compressed onto the piston rod by a garter spring (4). Gentle wiping action Simple retrofitting Rings made of extremely durable and flexible non-metallic material No restrictions with regard to Hydraulic edge works like a small oil manufacturer, packing design or Highest reliability Two-piece design Gaps are covered...
