Prior to the availability of Parker's Medium Pressure Filter series, applications were restricted by limitations of a spin-on can, or were forced into the higher cost range of high pressure filters. The need for economical, medium pressure range filters with excellent fatigue pressure ratings has been met by Parker Hydraulic Filter Division.

The Parker MPD Series Filters are an outstanding choice for today's demanding hydraulic control and circulating oil systems. The MPD's innovative modular design, rugged ductile iron construction and coreless element technology, combined with many other features, provide solutions across a broad range of industrial applications.

The Modular design provides user flexibility for simplex or duplex applications. Incorporating side chambers as simplex filters along with duplex installations provide common elements across the circuit design.

Construction features like full ported transfer valve with neutral center flow capability offer tremendous benefit in cold start conditions. Standard features like pressure sensing taps, vents, drains and internal pressure equalization make this product incomparable in industry.

Ecoglass III represents the merging of high performance filtration technology with environmentally conscious engineering. The Ecoglass III line of replacement elements feature 100% non-metallic construction. The design reduces solid waste and minimizes disposal costs for industry. The non-metallic construction means lightweight elements (60% less weight) for easier servicing.

The Ecoglass III elements utilize the same proprietary media design as our Microglass III line of replacement elements. With Ecoglass III, a reusable core is installed into the filter housing and remains in service throughout the life of the assembly.

The unique multi-layer design combines high efficiencies with exceptional dirt holding capacities for performance that is unequalled in the industry today. This performance is further enhanced in the MPD series with the introduction of the deep pleat design. The deep pleat element design increases the amount of media in the element and therefore increases capacity.

Typical Applications
• Circulating Lube Oil Systems
• Power Generation Control Systems
• Steel Mill Control Systems
• Pulp & Paper Control Systems
• Test Stands
• Automotive Stamping Presses
• Offshore & Land Based Oilfield Applications
