Leveraging more than 30 years of design and field experience, Pall presents 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, and not your equipment.
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 industryleading 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:
- Schneider Electric PLC1 and HMI
- Reliable Gardner Denver2 VLR series vacuum pump with 12 month service interval (8760 hours run time)
- Rickmeier3 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.

The Pall HDP Series of purifiers has a new vacuum tower design that maximizes water removal. The HDP50 removes 100 % of free, un-dissolved gases and water (under steady state conditions), and up to 80 % of dissolved gases and water. It also removes solid contaminants with efficiency of 99.95 % (down to 3 microns).
HDP Series oil purifiers showed a 40 % faster dehydration rate when compared with a typical purifier.
Pall HDP Series Purifiers come with the following standard features that many suppliers charge extra for:
- Dissolved Water Sensor (Pall model WS12)
- Athalon high performance BX(C) >2000 rated particulate filter
- Low watt density heater (15kw output)
- Pall Profile Star Coalescing Element to reduce risk of carry-over
Superior dewatering performance and a 300 cSt viscosity range increase (from top end 700 cSt to 1000 cSt) when compared to the Pall HLP50 Oil Purifiers, the Pall HDP50 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.
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 1000 cSt)
- No utility water required for cooling or pump operation – the only utility needed is an electrical power source
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 the maintenance 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 even under challenging conditions”.
- Extended vacuum pump oil change interval – 12 months (8760 hours of run time)
- No water utility for cooling or pump operation
