APPLICATION
The CJC™ HD HDU 15/25 Heavy Duty Filter is used for
the maintenance of fluids for power transmission, lubrication
and cooling, under severe conditions such as the mobile
machinery in mining and the forest industry. The filter
is mounted on a shock absorbed back-plate. Furthermore, the
electrical motor is dust and waterproof and designed for high
pressure washing.
To prevent leaks due to shocks/vibration, the filter is equipped
with a minimess test-nipple for pressure readings (a pressure
gauge prepared for minimess connection is included).
Furthermore, the filter is equipped with a pressure switch.
The HD HDU 15/25 is ideal for removal of particles, degradation
products and water.
FUNCTION
The filter pump draws fluid from the system tank (at lowest
point) and pumps it through the filter insert. From the
centre of the insert the fluid flows through the filter house
and returns to the tank.
The pressure drop across the filter insert - and consequently
the contaminant absorption of the filter insert - is monitored
on the pressure gauge on the filter top.
The filter outlet port is placed in the filter base. The filtered
fluid is to be returned to the tank close to the suction pipe of
the main system pump.
Note that the return point should be non-pressurized.
Contact us if this is not possible.
THE FILTER PUMP
The filter pump is a CJC™ gear wheel pump. The motor can
be supplied as standard AC motors, 24 VDC, and as a hydraulic
motor.
FILTER INSERT
The CJC™ Filter Inserts consist of several discs bonded together.
Depending on the fluid to be filtered, the material is
either cellulose or cotton linters.
OPTIONS
„P C4 Painting „P Minimess (oil sampling)
„P Control Box „P Coalescer
„P Particle Removal
All CJC™ Filter Inserts have the following filtration
degree:
- 3 ìm absolute:
98.7% of all solid particles >3 ìm
- 0.8 ìm nominal:
50% of all solid particles >0.8 ìm
are retained in each pass.
The dirt holding capacity is 1,5 L of evenly
distributed solids.
„P Degradation Products
Oxidation products, resin / sludge, and varnish are
retained by the cellulose material, which will retain
appr. 1 kg of oil degradation products.
„P Water Removal
The water absorption potential is up to 50% (i.e. 750
mL H20) of the total contaminant holding capacity.
