New: HDP10 Series Oil Puriﬁer
for ﬂuid viscosities up to 1000 cSt
PIHDP10EN

Water in hydraulic, lubrication, heat transfer
and insulating fluids adversely affects fluid
performance and is a threat to system reliability.
The HDP Series of purifiers combine the water removal
performance of mass transfer technology 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 theequipment.
The Pall HDP Series of purifiers has a new vacuum
tower design that maximizes water removal. TheHDP10 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 to 3microns).

Maximum Reliability, Lower Costof Ownership
HDP series purifiers implement a design for maximum
uptime, tightly based on historical Pall purifier design,
which exhibits higher utilization rates even in the mostdemanding and continuous duty applications.
The HDP10 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

HDP10 Series Oil 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 (8kw output)• Pall Profile Star Coalescing Element to reduce

pump with 12 month service interval (8760 hoursrun time)risk of carry-over• Rickmeier3 gear pumps — proven performers forControlling the dissolved as well as the free water in thereservoir is critical in ensuring the absence of free water
during operation. With the Pall HDP10 purifier, this isdone efficiently, easily and reliably. The diagram below
illustrates the concept.

Initial oiltemperature

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.

Flexible Flow Rates

Ease of Use

The HDP’s variable frequency inlet drive allows forefficient oil purification performance at flow rates
ranging from 6-10 GPM (60 Hz) / 23-31 LPM (50Hz).

The HDP10 series offers the following features to increase
versatility in service and lower cost of ownership:

Additional Design Improvements• Able to work with wide range of oil viscosities(3 cSt to 1000 cSt)

• Low maintenanceSuperior dewatering performance when compared tothe 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 todisplay water content PPM (parts per million) in mostcommonly available hydraulic and lube oils, giving
you an all-in-one solution to measure and ensure oilquality. (2) Larger outlet check valves ensure reduced
backpressure for more efficient, quieter running. (3)Upper tower level vacuum pump protection enabling asafe shutdown.

Dimensional Drawings• No utility water required for cooling orpump operation

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