4. Scope of delivery
4.1 Scope of components
The unit is supplied with a set of hydraulic hoses. The suction hose DN8 is installed in the suction port of the pump. The oil sucked
from the system / barrel is pumped by the pump into the main filter and then, after being filtered, it is transferred to a DN6,5
discharge hose, connected to the filter output. Both hoses are provided with plugs in order to avoid a possible leakage of residual oil
during storage and transport. The plugs are installed on the free ends of the hoses. The CFP unit is delivered with electric cable and
electric plug.
4.2 Additional components
One additional component for the CFP Compact Filter Pack is a return-suction set (the picture below). The set has to be ordered
separately.
Fig. 1: Additional component: suction-return set
If the suction-return set is installed in plastic tanks, additional adapter has to be ordered (the picture below). The adapter has to be
ordered separately.

5. About this product
5.1 Performance specification
The CFP is a portable service unit dedicated to oil pumping, tank filling and off-line filtration of hydraulic fluids and lubricants with a
viscosity of 10 mm2/s - 600 mm2/s (in continuous operation) or 800 mm2/s max. (in short-term operation).
The volume flow is 3 l/min (50 Hz).
The operating temperature is in the range of 0 °C to 60 °C.
5.2 Device description
The Compact Filter Pack CFP consists of a support frame in which the following major units are integrated:
1. A filter pump unit consisting of a gear pump and an electrical 1-phase motor. The pump is equipped with 3.5 bar pressure relief
valve and a suction filter of 700 µm filter fineness. The motor is equipped with an ON/OFF switch and a power cord with a plug.
2. A filter with an exchangeable filter element and a gauge as maintenance indicator. The clogging indicator indicates the need to
replace the filter element. Depending on the needs there are filter elements of a different filter fineness: 5, 10, or 16 µm.

6. Transport and storage
6.1 Transport
CAUTION
Falling unit through incorrect transport
Injury and property damage
›Wear safety shoes when transporting the filter unit.
A plastic holder is attached to the unit’s frame to make its transport easier. Due to the fact that the weight does not exceed 10 kg,
the device can be carried manually. When carrying the device, ensure a secure position of the unit and make sure that the handles
are free from residual oil. This will prevent undesirable slipping of the device and falling on the feet of the person carrying the unit.
The bottom part of the frame also serves as the base of the unit and as a collecting tray where the residual oil is collected.
The filter unit CFP should be stored in an enclosed area to protect it from humidity and condensation.
6.2 Storage
The ambient temperature during storage of the filter unit CFP should be between + 5 °C and + 30 °C at a humidity of 80%.
Before storage over a period of more than 6 months, the unit should be filled with oil in order to preserve it against corrosion.
CAUTION
CAUTION
Risks related to chemical reactions
Risk of injury
›Chemical substances in the immediate vicinity of the filter unit may react and lead to destruction of the
device and to injuries of persons who are in the immediate vicinity of the device.
›Storage in the immediate vicinity of chemically active substances such as acids, alkalis, salts, organic solvents
and rechargeable batteries is prohibited.
