Leveraging more than 30 years of design and field experience, Pall delivers the third in its family of HDP Series fluid conditioning purifiers—the HDP50 Oil Purifier.

The HDP series combines the water removal performance of mass transfer purifiers with high reliability and ease-of-use to help ensure maximum equipment uptime and lowest cost of ownership - enabling you to focus on your process, not on your equipment.

Improved Performance

The Pall HDP series purifiers feature an innovative new vacuum tower design that maximizes water removal efficiency.

Maximum Reliability, Lower Cost of Ownership

HDP series purifiers are designed for maximum uptime and have proven themselves in the field with industry-leading utilization rates even in the most demanding and continuous duty applications.

The HDP50 uses specially selected components to help ensure maximum reliability and lower cost of ownership. These premium components include:

• Best-in-class Schneider Electric PLC
• Reliable Elmo Rietschle vacuum pump with 12 month service interval
• Rickmeier gear pumps – proven performers for more than 20 years in Pall Purifiers

Controlling the dissolved as well as the free water in the reservoir is critical in ensuring the absence of free water during operation.With the Pall HDP50 purifier, this is done efficiently, easily, and reliably. The diagram below illustrates the concept.

Ease of Use

The HDP50 series offers the following features to increase versatility in service and lower cost of ownership:

• Low maintenance
• Able to work with wide range of oil viscosities (3 cSt to 700 cSt)
• No utility water required for cooling or pump operation— the only utility needed is an electrical power source

Standard Features

Pall HDP Series Purifiers come with the following standard features that many suppliers charge extra for:

• Dissolved water sensor (Pall model WS12)
• Low watt density heater (30kw output)
• Pall Profile Star Coalescing Element to reduce risk of carry-over

Focus on your Process, Not on your Purifier

HDP Series Purifiers requires the minimum of user interaction, which allows users to focus more on their process and less on maintaining and upkeep of their purifier.

The HDP purifier is one of the easiest purifiers to operate. Simply connect the purifier to the reservoir, power up, and press the start button. “Our standard is that the HDP users are able to just press the button and walk away.”

• Extended vacuum pump oil change interval—12 months (8760 hours of run time)
• No water utility for cooling or pump operation

Design Improvements

Beyond equal to better dewatering performance when compared to the Pall HLP Oil Purifiers, the Pall HDP Oil Purifiers boast a series of design improvements over past versions. (1) The HDP will come standard with the ability to display water content PPM (parts per million) in most commonly available hydraulic and lube oils, giving you an all-in-one solution to measure and ensure oil quality. (2) Larger outlet check valves ensure reduced backpressure for more efficient, quieter running. (3) Upper tower level vacuum pump protection enabling a safe shutdown in challenging conditions
