PTU2 27/27

CJC™ Filter Separator - D I E S E L

CJC™ Product Sheet
APPLICATION

The CJC™ Filter Separator PTU2 27/27 Diesel is used on
diesel oils with a specific weight lower than that of water.
The PTU2 27/27 is ideal for separation of water, removal
of particles and degradation products.

FUNCTION

The filter pump draws oil from the settling/bunker tank and
presses it through the filter insert. From the centre of the insert the oil flows down into the filter base where water droplets adhere to the coalescer element, forming larger drops that
will settle in the bottom of the filter base. From the top of the
filter base the oil will flow to the service tank or back to the
settling/bunker tank.
The filter suction pipe should be connected to the bottom of
the settling/bunker tank, above the tank drain tap. The filter
outlet should be lead to the service tank.
An overflow line from the top of the service tank back to the
settling tank should be applied in order to secure that surplus
oil flows back to the settling/bunker tank.
On the PTU with automatic water discharge, separated water
is drained automatically. The discharge function can be monitored on the unit control box. The PTU models are also available with manual water discharge.
The pressure drop over the filter - and consequently the contaminant absorption of the filter insert - is monitored on the
pressure gauge on the filter top.

THE FILTER PUMP

The CJC ™ Filter Separator
PTU2 27/27 PV-E2W

The filter pump is a CJC gear wheel pump. The electric motor
can be supplied for all standard AC and DC voltages.

FILTER INSERT

The CJC™ Filter Inserts consist of several discs bonded together. The material is either cellulose or cotton linters depending on the fluid to be filtered.

Water Removal by Separation
The CJC™ Filter Separator removes water from oil to very
low levels. The efficiency of water removal depends on the
oil type and temperature.

Particle Removal
All CJC™ Filter Inserts have the following filtration
degree:
- 3 μm abs.: 98.7% of all solid particles >3 μm
- 0.8 μm nom: 50% of all solid particles >0.8 μm
are retained in each pass.
The dirt holding capacity is 4 litres of evenly distributed solids.
Degradation Products
Oxidation products, resin / sludge, and varnish are
retained by the cellulose material, which will retain
appr. 4 kgs of oil degradation products.
Preheating the oil before filter pass may be necessary to prevent segregation of paraffin, but only with blended fuels.
