KLEENOIL Hydraulic Applications

SDU9788KU85HYD

Advisory: Installing the Kleenoil SDU9788KU85 Unit with PRV Block on a Machine’s Hydraulic Line Installation Guidelines Installation Method: Bypass Circuit Install the Kleenoil unit on a bypass line rather than the main pressure or return line. This allows the system to operate continuously without interrupting or throttling the machine’s normal hydraulic functions. 1. Component Overview Filtration Unit : Kleenoil SDU9788KU85 PRV Block Assembly : Flow Regulator (Optional) : Inline flow restrictor or orifice plate to ensure steady flow 2. Step-by-Step Installation Step 1 : Identify Tap-In Point (Pressure Source) 3. Locate a high-pressure access point on the hydraulic line, such as a test port or spare auxiliary port. Pressure must not exceed 3000 PSI at this point. Step 2 : Install the PRV Block Assembly Connect the source pressure line into the inlet port of the PRV block. The Danfoss PRC06E05000 will reduce pressure to ~40 PSI. The Lee Spring poppet mechanism provides safety relief in case of downstream blockage or spikes. Step 3 : Connect to the SDU9788KU85 Vessel Sample Port : Upstream or downstream of the unit Flexible Hoses or Hard Lines : For return to tank Run hydraulic hose from PRV block outlet to the inlet of the Kleenoil unit. Ensure proper support/bracketing for stability and vibration isolation. Step 4 : Return Line The filtered oil outlet should be connected to: o The hydraulic reservoir return port , OR o A low-pressure return line (under 5 bar). Avoid backpressure beyond design limits. Step 5 : Sample Port Installation Install the sample port just before the filter inlet or after the outlet , depending on monitoring preference. Use a test port with quick-connect for oil analysis or pressure readings.
