Medium Pressure Filters

Transcription

1 Medium Pressure Filters Medium pressure filters can be used in applications up to 2 psi (1379 kpa). Donaldson offers both spin-on and in-line cartridge-style filters. Medium Pressure Filters MEDIUM PRESSURE FILTERS Donaldson Duramax filters are the highest rated medium pressure spin-on filters available. Duramax filters are proven, reliable, long-lived and easy to install.

It features a die cast aluminum head and a unique radial seal O-ring gasket design that eliminates leakage. Take advantage of Donaldson s mix and match system of in-stock heads, housings and media choices so you can get exactly what you need. A full range of media options are available, using Donaldson s exclusive Synteq synthetic media designed especially for liquid filtration. You can also select the exact indicator types and bypass options to suit your application.

A special head-to-canister O-Ring seal prevents leakage. Buna-N seals are standard; Viton seals are available on some models. Since both HMK4 and HMK24 models use the same replacement filters, they make a great team for your application. Both filters feature identical pressure ratings, but HMK24 handles double the flow capacity as HMK4, so there s no need to inventory two different part numbers for replacement filters.

"Left side," for instance, means that the indicator mounts on the side of the filter head that is on your left when you face the inlet port. 3-Port Head for Charge Pumps The P17529 head is designed with a 5 psi / 3.45 bar third port bypass valve that diverts all bypass flow back to the reservoir, instead of going straight through the head and into the system as it does in 2-ported heads. Unfiltered fluid is NOT allowed into the system in the case of plugged filters. Designed primarily for charge pump applications.

A special head-to-canister O-Ring seal prevents leakage. Buna-N seals are standard. Viton seals made of fluorocarbon are available. Since both HMK5 and HMK25 models use the same replacement filters, they make a great team within your application. Both filters feature identical pressure ratings, but the HMK25 double filter head means double flow capability, with two filters to hold more contaminant. So there s no need to inventory two different part numbers for replacement filters.

Differential Indicators: Indicators are designed to actuate at approximately 8% byass valve cracking pressure. It is recommended that an indicator with a bypass setting of 1 psid is used with a non-bypass housing. Surge Control: This optional feature is used to dampen pressure surges or spikes to avoid premature actuation of the indicator. Surge control delays the indicator response. Thermal Lockout: The Thermal Lockout prevents premature signaling of a bypass condition created by viscous fluid during cold start-ups. Normal indicator actuation capability is resumed once the operating temperature of the fluid reaches approximately 8 F / 27 C. Hydraulic Filtration 17

38 Donaldson Delivers Replacement Filters for Pall Ultipleat SRT Housings Pall and Ultipleat are registered trademarks of Pall Corporation. COMING SOON Better by Design The Donaldson hydraulic product line is expanding to include replacement cartridges for Pall Ultipleat SRT319 style housings. These Donaldson cartridge filters provide optimum protection from particles and contaminants that reduce the effectiveness of lubricant and hydraulic fluid. Using Donaldson Synteq media technology, these filters have long life, high initial cleanliness and provide excellent system protection. High-performance cartridge filters feature an advanced pleat pack design that provides high initial cleanliness and dirt holding capacity. Double wire backed with an epoxy-coated steel mesh for excellent pleat support and spacing, which allows for maximum media area and effective protection during operating pressure surges Utilizes glass fiber Synteq media with an epoxy-based resin system and is potted with epoxy-based adhesives Viton O-ring seals for excellent fluid compatibility Viton is a registered trademark of E. I. DuPont de Nemours and Company. Utilizing DT Synteq Media Technology Donaldson-developed DT Synteq synthetic filter media has smooth, rounded fibers for low resistance to fluid flow. This media is ideal for filtering synthetic fluids, water glycols, water/oil emulsions, petroleum-based and high water content fluids (HWCF). High-efficiency media grades with performance to ß<4 (c) =1 (per ISO 1889) Exceptionally low flow resistance Consistent performance throughout filter life Electrostatic Discharge (ESD) Reduction SRT replacement filters are designed to resist charge generation and reduce the occurrence of electrostatic discharges induced by the flow of fluids through the filter media a known industry problem which can result in damage to the filter and degraded performance. Proven Protection These cartridge filters are reliable protecting systems from harmful ingressed contaminants. The inside to outside flow path reduces the likelihood of cross-contamination during filter service. 12 Hydraulic Filtration
