RMF Systems Bypass Units – BPU2A

Product Enquiry

Description

RMF Systems By-pass filters are specifically designed for mobile hydraulic installations and are available in single or double units which are equally suitable for OEM use and retrofitting.  The By-pass filter comes equipped with an integrated pressure compensated flow control valve.  This valve bleeds oil from the main hydraulic system, passes through the filter after which it is returned to the hydraulic reservoir.  The amount of oil extracted from the main system at any time is insignificant ensuring that it will not affect the working of the main system.

The hydraulic market accepts that 80% of mechanical failures are caused by contamination of the oil.  The RMF Systems By-pass filters attack this contamination at source and in addition to solid particles, these filters are also capable of removing water from the oil.  This prevents the catalytic reaction of water and solid particle contamination, resulting in extended usable oil life.  The use of RMF Systems By-pass filters means less defects, less maintenance, and less wear and tear of the hydraulic components.
