HYDRA-SUPREME FLUID SCRUBBING SYSTEM
MODEL 810-050.2
STOLLE MACHINERY EQUIPMENT APPLICATION
INTRODUCTION:
HTI Filtration fluid scrubbing systems are high performance industrial filters designed to
remove particulate, oxidized oil and water from hydraulic and lubricating fluid systems.
Model 810-050.2 is specifically designed for cleaning the combination lubricating/hydraulic
oil in Stolle body makers where 3 phase power is required. Manufactured from durable
corrosion resistant materials, it is designed for constant, uninterrupted use without
immediate supervision. This system will assure the required high degree of fluid purity with
an absolute minimum of maintenance and service requirements.
SYSTEM OPERATION:
The fluid scrubbing system utilizes a patented cellulose element to clean the working fluid
of accumulated debris.Thecleaning process utilizesthree interlocking processes to remove
solid particulate, varnish and water from the oil. By combining barrier filtration,
chromatographic separation and absorption, all three of the listed contaminants can be
removed from the oil simultaneously and efficiently. As the filter traps the contaminants, it
builds up resistance and the pressure rises. At 60-65 PSI, the pressure switch activates to
alert the operator of the need for filter replacement.
The proper function of the filter depends on the correct placement of the inlet and return
lines, the correct flow volume, delivery, and pressure. The transfer lines should pull fluid
from the reservoir and return it to a location at least 24" away from the inlet port to prevent
recirculating the same oil over and over. The rotary ring gear pump provides extremely
smooth fluid delivery to prevent pulsation from dislodging debris from the filter element.
Combiningsmoothdeliverywiththeproperflowvolumeassureshightrappingefficiencyand
long element life. Under normal conditions, your 800-026 element should last 1-2 months
before requiring changeout. The filtration efficiency begins to drop off sharply as the
pressure rises above 60-65 PSI and the filter element may begin shedding debris back into
the oil above 70 PSI.

SYSTEM PRESSURE:
Pressure readings will vary with the viscosity of the oil used, the operating temperature of
the reservoir, and the amount of debris absorbed by the filter.
Typical start-up pressures using 750 SUS/ ISO 150 oil at 1000-1200F is 12-18 PSI.
Typical change out point is 60-70 PSI or a 50-PSI increase in original operating pressure
but not to exceed 75 PSI.
Pump output pressure is controlled by a non-adjustable, external valve and an
adjustable internal relief valve that is factory set to open at 70 PSI and go into complete
bypass at 90-PSI maximum. Do not tamper with the internal valve assembly. Simply
removing the acorn nut can result in an intake air leak that will require a new gasket to
correct.
Under no circumstance should your unit ever exceed 90 PSI. Should this occur, shut down
the system and contact the HTI Filtration Technical Service Department at [phone]
or email [e-mail] for assistance.
SYSTEM LOCATION:
Although the Hydra-Supreme system uses a self-priming pump, it is important to keep the
filter as close to the reservoir as possible. The suction line should be less than 8' long and
use ¾” fittings throughout the delivery line.
Set the filtration system on a solid, level surface. Allowa minimum of24" of frontal clearance
for service access. Filter system should be kept free of moisture and under 140oF.

PLUMBING:
The suction port utilizes a 3/4" inlet with 37 deg JIC hose fittings. A maximum hose length
of 8' is recommended as is the use of sealing caulk or tape on all threaded fittings.
The return port utilizes a 3/4" line with JIC hose fittings. Sealing caulk or tape is also
recommended on all threaded fittings.
Ball valves can be installed on both connections for easy shut-off during installation,
adjustment or service.
ELECTRICAL:
The filter power system should be independent of the machine power, as the oil scrubbing
system should run continuously for efficient contaminant control.
The motor for 810-050 systems operates on both 200-400 VAC 50Hz & 230-460 VAC 60
Hz 3 Phase power sources.
Motors are also available for 575 Volt-60Hz systems upon request.
The pressure switch operates on 24 VDC power exclusively.
INITIAL START-UP PROCEDURE
Upon completion of the electrical and hydraulic connections, the filtration system is ready
for start-up. The pressure relief valve is factory set for a maximum pressure of 90 PSI. If
yourunitexceedsthislevelduringanyphaseofoperation,turnitoffimmediatelyandcontact
HTI Filtration for instructions.
Open all valves on the inlet and return lines.
Crack open the bleed valve on the top of the canister.
Turn on the pump.
Close the bleed valve as oil starts to flow from it.
Confirm that the start-up pressure is between 12-20 PSI at 100 -120 F.
Check for fluid leaks before leaving the area.

Field Adjustment of Pressure Switch
Thepressureswitchcanbefieldsettoaccommodatelocalcircumstancesorpreferences.Theswitch
comespreset from our factory and should only be changed if you are encountering problems. Before
changing any settings on an HTI System, run the body maker until the oil is at the normal operating
temperature (typically between 100-120°F).
1. Turn filter system on and allow oil to fill the canister while venting the air
through the bleed cock on the canister lid.
2. As soon as fluid flows from bleed cock, close and secure.
3. Slowly close the outlet hose ball valve until the system pressure is at 55-58 PSI as
shown on the pressure gauge atop the canister.
4. Remove clear cover of pressure switch. Rotate yellow ring to ‘UNLOCK’ position.
Adjust the set point by rotating the SET ring until the LED illuminates. The RESET
ring should be set 5 PSI below the level of the SETring. Place the cover back on the
switch and open the ball valve to restore full flow to the filter. The filter pump and
safety relief valve will start to bypass oil internally at 60 PSI so setting the pressure
sensor higher will defeat the purpose of informing the operator of a pending filter
change out.
NOTE: Do not attempt to reduce or increase the operating pressure by adjusting the internal
pressure relief valve on the pump. This safety devise has been set and locked into place at the
factory. Attempting to adjust the pressure setting screw can jam the relief valve and prevent proper
movement. Improperly removing the acorn nut may also result in air leaking into the system, which
will require frequent system bleeding until the acorn nut seal is replaced.

FILTER ELEMENT REPLACEMENT
Step 1:Turn off the Filter System. It is not necessary to turn off the bodymaker to service the filter.
Step 2:Open the drain cock on the bottom of the canister, and then open the bleed cock on the top
of the lid. The drain hose can be used to direct the draining oil to a receptacle. Drained oil
can later be used to refill the canister.
Step 3:Remove the canister clamp ring and lift off the canister lid.
Step 4:Examine the canister “O” ring for cracks and wear spots. If the canister lid seal was
leaking, or if the “O” ring shows signs of wear, replace the ring.
Step 5:Unscrew the “T” handle assembly that holds the filter in place by rotating the handle in a
counterclockwise motion. The cup seal on the handle assembly should be smooth and
free of rough spots or tears. Replacement seals are available.
Step 6:Slice open the end of the plastic bag holding the new element. Remove the new element
and set in a clean area. Lift used element off of center post
Step 7:Slide new filter over the center post. Make sure the wire lifting bale is at the top and the
black O-ring is at the bottom. Secure the element with the “T” handle by screwing it back
into the center tube with a clockwise motion until it seats.
Step 8:Close drain cock and refill canister with oil.
Step 9:Put the “O” ring back on the canister lip, replace lid, clamp and tighten.
Step 10: Start the pump motor and allow air to bleed out through bleed cock on top of canister.
Close bleed cock when fluid starts to come out. Wipe off unit and check for leaks.
