4.2 Operating curves
4.2.1 How to read the diagrams:
The following diagrams show 2 curves, one continuous and one with a dotted line.
The continuous line shows the water owrate at a specic operating pressure. The dotted line shows the motor oil pressure.
Example: Diagram of a pump (Code 9700502x) with a motor of 7,2 cm3:
To obtain a water owrate equal to 340 l/min with a pressure of 5 bar (1), the pump will have to be powered by an oil circuit that can guarantee a
owrate of 26,5 l/min with a pressure of about 128 bar (2).

5.3 Attachment
The MP400 series pumps are equipped with an attachment with a drilled plate that allows the positioning also in very narrow areas or where there is
just the space for the pump. Use M8 screws and bolts for the xing.
IMPORTANT:
IN ORDER TO INSTALL THE PUMP CORRECTLY, OBSERVE THE FOLLOWING PRECAUTIONS:
1) The inlets/outlets must be placed in xed positions.
2) Before drilling and xing the plate, check the actual space according to the different types of motors or pulleys.
3) Take into account the spaces needed for the correct positioning of the hydraulic pipes, where provided, or the power cables.
4) Choose a well ventilated point for the positioning, as the pump will become hot while in operation.

6 CONNECTIONS
6.1 Hydraulic motor (OIL) connections
6.1.1 Safety guidelines
- Use tubes that are suitable to the motor owrate and pressure (ref. Tab. 1).
- Fix the hydraulic tubes checking that after their use under pressure there are no blow-by or oil leakages from the circuit.
- Do not install the pump where it can be subject to severe impacts, or where there is too much heat or in any other point that
can cause the machine to malfunction.
-During the insertion in an existing system, follow all the safety guidelines indicated by the system manufacturer.
-Qualied staff must carry out any type of intervention that requires the modication of the original hydraulic connection
conguration.
ARAG is not liable for damages to equipment, persons, animals or property caused by wrong or unsuitable pump connections.
Furthermore, ARAG can not be held responsible for direct or indirect damages to equipment, machinery, persons or animals
caused by the use of pipes, cable clamps, ties, or any other connection or by the use of unsuitable and improper accessories.
Damages to the pump or to the circuits/objects connected to it, due to the above-mentioned causes, automatically voids the
warranty.
6.1.2 Hydraulic motor oil line connection
in
out
IMPORTANT:
TO AVOID THE BREAKAGE OF THE MOTOR, PAY ATTENTION NOT TO INVERT THE OIL TUBES CONNECTION.
For this purpose, it is recommended to install a check valve.
ARAG check valve (Code 970001 - Ref. ARAG Catalog), to be purchased separately, must be installed in the oil output branch
(out) PAYING ATTENTION TO THE REFERENCE OF THE FLOW DIRECTION, as indicated on the valve body (Fig. 7).
Use the gaskets provided and a tightening torque of 20 Nm.
ARAG is not liable for damages to the system, persons, animals or property caused by the use of a check valve different from the
one indicated. The warranty is to be considered automatically void in case of damages to the pump caused by failure to observe
the above-mentioned instructions.
- The maximum value of the back pressure on the outlet is 3 bar.
- The oil outlet line (drain) should be directed into the oil tank.
- The pipelines must have a nominal diameter not lower than the diameter of the ttings on the motor and they must be perfectly
sealed.
- To avoid loss of pressure, the pipelines should be as short as possible reducing to a minimum the number of hydraulic
resistances (elbows, bottle necks, quick-couplings).
- It is advisable to place a section of exible tube in between the pipelines, this is to reduce the transmission of vibrations.
- All the return pipelines must end below the minimum oil level, this is to avoid the formation of foam.
- Before connecting the pipelines, remove all closing plugs, if any, and make sure they are perfectly clean.

6.2 Water connection
6.2.1 Safety guidelines
- The pump must always be installed below the liquid level.
- The suction line must be as short and direct as possible.
- Avoid elbows and the enlargement of the diameter in the pipeline to avoid air stagnation.
- The size of the suction and delivery lines must be AT LEAST equal to the nominal diameter of the size of the relevant opening.
- The suction line must be free from air leaks.
- Avoid, if possible, elbows and narrowing in the pipeline on the delivery line, this is to limit possible loss of pressure.

6.2.2 Water/air bleed
- Install a breather pipe (Item 2 Fig. 2) in one of the delivery retaining plugs placed on the pump.
The tube diameter must be 6 mm or 1/4".
- Choose the plug located in the highest point according to the installation position of the pump (Fig. 9) in order to eliminate any
air trapped in the pump and to allow a minimum motion of the liquid also when the control unit connected to the pump is not
spraying.
