HIGH PRESSURE FILTERS

Transcription

1 APPLICATION HIGH PRESSURE FILTERS For Manifold Block Mounting Series DF...P Pressures to 45 psi Flows to 18 gpm HYDAC DF...P High Pressure Filters are designed to be mounted directly onto the manifold block to save space and reduce leak points and mounting hardware. These filters can be installed on the high-pressure side of the pump to protect control valves and actuators from contamination. PRODUCT FEATURES Models DF 6-24 P have a steel filter head and screw-in bowl made of cold-formed steel. The DF 33 P and DF 66 P have a filter head of ductile iron and a screw-in bowl of cold-formed steel. The filter housings are designed to withstand pressure surges as well as high static pressure loads. The screw-in bowl allows the filter element to be easily removed for replacement or cleaning. A visual (pop-up), electrical, electrical/visual (lamp), or electronic differential type clogging indicator can be installed. DF...P filters are available with or without a bypass valve so either high or low collapse pressure elements may be used. Multiple indicator port locations (DF33/66P only) also allow two different types of indicators to be installed into the filter. Indicators of the same type, but with different trip pressures can also be installed. FILTER ELEMENTS DF...P Manifold Mounting Filters DF...P Filters are available with disposable Betamicron Low Collapse (BN3HC) elements having 25 psid and Betamicron High Collapse (BH3HC) having 3 psid collapse pressure and absolute ratings of 3, 5, 1, and 2 micron. DF...P Filters are also available with cleanable elements. Metal Fiber (V) stainless steel fiber elements have a 3 psid collapse pressure and nominal ratings of 3, 5, 1, and 2 micron. Wire screen (W/HC) elements have a 25 psid collapse pressure and nominal ratings of 25, 74, and 149 micron. For nonbypass applications, Betamicron (BH3HC) or metal fiber (V) elements must be installed. If a bypass valve is used, Betamicron (BN3HC) or wire screen (W/HC) elements can be installed. All filter media is supported to achieve flow fatigue resistance. Proper support of the filter media also provides high Beta Ratio values (particle removal efficiency) even at high differential pressures. The efficiency of many competitive elements drastically deteriorates as the element clogs and differential pressure increases. High quality epoxy adhesive is used to bond the end caps to the media and to bond the seam of the media.

5 Filter Sizing Calculations: Assembly: To calculate the pressure drop of the filter assembly use the equation: ÆP Assembly = ÆP Housing + ÆP Element Housing: The housing curve is based on test results using mineral oil with a specific gravity of.86. Differential pressure increases in proportion to specific gravity of applicable fluid. To adjust the housing ÆP for the fluid being used, use the equation: ÆP Housing = ÆP Curve x Actual Specific Gravity.86 DF 6/11 P Housing DF 16/24/28 P Housing DF 33/66 P Housing ÆP in bar ÆP in bar ÆP in bar Q in l/min Q in l/min Q in l/min Bypass Valves Curve: Curves shown are applicable for mineral oil with a specific gravity of.86. Differential pressure increases in proportion to the specific gravity of the fluid. To adjust the bypass ÆP for the fluid being used, use the equation: ÆP Valve = ÆP Curve x Actual Specific Gravity DF 6/11 P 2 DF P DF 33/66 P

6 Element ÆP Calculations: All element curves are based on test results using mineral oil with a kinematic viscosity of 141 SUS and a specific gravity of.86. The differential pressure across the element changes proportionally to the viscosity and specific gravity. ÆP Element = ÆP Curve x Actual Specific Gravity Actual Viscosity x Wire Screen Elements: To find ÆP across clean wire screen element divide application flow by maximum recommended flow and find percentage; then read ÆP from graph.
