New: HDP50 Oil Puriﬁer

PIHDP50EN

Description
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 OilPurifier.
The HDP Series combines the water removal
performance of mass transfer purifiers with highreliability and ease-of-use to help ensure maximum
equipment uptime and lowest cost of ownership –enabling you to focus on your process, and not yourequipment.

Improved Performance
The Pall HDP series purifiers feature an innovative newvacuum tower design that maximizes water removalefficiency.

Maximum Reliability, Lower Costof 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:

HDP50 Series Oil Purifier• Schneider Electric PLC1 and HMI• Reliable Gardner Denver2 VLR series vacuumControlling the dissolved as well as the free water in thereservoir is critical in ensuring the absence of free water
during operation.

• Rickmeier3 gear pumps — proven performers forWith the Pall HDP50 Purifier, this is done efficiently,easily, and reliably. The diagram below illustrates theconcept.

Removing free water is never enough!

1 Initial water content is above saturation(free water).
2 Maximum water removal capability of‘free water removal’ devices (coalescers,centrifuges, etc.) is to the oil’s saturation
point.
3 Water content achieved with masstransfer dehydration is significantly below
the oil’s saturation point.
4 Water content achieved with masstransfer dehydration remains below theoil’s saturation point even after oil iscooled. This prevents the formation of freewater, harmful to the system.
5 If only free water is removed at initial
temperature, when oil is cooled theamount of harmful free water in the oil
can increase signifcantly.

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 asafe shutdown.

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 andwater (under steady state conditions), and up to 80% of dissolved gases and water. It also removes solid
contaminants with efficiency of 99.95 % (down to3 microns).

Ease of Use
The HDP50 Series offers the following features
to increase versatility in service and lower cost ofownership:

HDP Series oil purifiers showed a 40 % fasterdehydration rate when compared with a typical purifier.

• Low maintenance• Able to work with wide range of oil viscosities

Standard Features(3 cSt to 1000 cSt)

Pall HDP Series Purifiers come with the following
standard features that many suppliers charge
extra for:• No utility water required for cooling or pump 			operation – the only utility needed is an electricalpower source• 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-overDesign Improvements
Superior dewatering performance and a 300 cSt viscosity
range increase (from top end 700 cSt to 1000 cSt) whencompared to the Pall HLP50 Oil Purifiers, the Pall HDP50
Oil Purifiers boast a series of design improvements overpast versions. (1) The HDP will come standard with theability to display water content PPM (parts per million)
in most commonly available hydraulic and lube oils,

Focus on Your Process, Not onYour Purifier
HDP Series Purifiers requires the minimum of userinteraction, which allows users to focus more on theirprocess 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 theHDP users are able to just press the button and walkaway 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
