A4VSO piston pump Rexroth A4VSO pump


– spacers, with function of • keeping roller axis parallel • creating space between rollers to hold more oil
– spacer rings, with function of • keeping rollers lined up • absorbing axial forces coming from connection rod

INTERMOT produces RADIAL PISTON HYDRAULIC MOTORS since 1985: our yearly production is more than 13.000 units which we sell all over the world through our agents and authorized sellers. Our motor range varies from 20cc to 8500cc displacement and it is completed by two-speed motors and special motors created in cooperation with our clients for different applications such as : underwater, high & low speed and wheel motors and with the possibility to assemble valves, brakes or gear reductions. You can directly contact our Technical Department which will give you all the necessary support to find the right solutions to your problems.
INTERMOT is a flexible work reality and manages deliveries also within the same day of order; we produce motors exactly interchangeable with our competitors, always ready on stock which our clients particularly appreciate.

INSTRUCTIONS AND ADVICES
INSTALLATION
Hoses and piping must be clean and free from contamination. No other special requirements are necessary.
- Motor can be mounted in any position
- In run-away conditions you must use counterbalance valves
- Consult factory for intermittent applications splined adaptors (sleeves) are available upon request.
INSTALLATION CIRCUIT
The choice of open or closed loop circuit will be determined by the application. Open loop circuits are cheaper and simpler to install.
Closed loop circuit is a superior circuit and usually takes up less space. It also offers better control features.
START UP
Motor case and pistons must be completely filled with oil before starting. Do not load motor to maximum working pressure. Increase load gradually at start-up.
CASE DRAIN – CASE PRESSURE
Connect the case drain directly to tank. The case drain port on the motor must be located on the highest point of the installation to ensure that the motor will always be full of oil. The case drain pressure must not exceed 6 bar continuous pressure.
IMPORTANT
When the motor is installed vertically with shaft pointing upwards, consult our Technical Department. If the motor is connected to high inertial loads, the hydraulic system must be designed to prevent peaks of pressure and cavitations.
TEMPERATURE
Maximum oil temperature must not exceed 70°C. Heath exchangers must be used with higher temperatures.
VISCOSITY
The motor works satisfactory in a range of 3°E to 10°E oil viscosity. Best performance is obtained at the highest viscosity.
BACK PRESSURE
Don’t exceed 70 bar back pressure.
HIGH PEAKS APPLICATIONS
In case of high pressure peaks applications, a Nitemper treatment on cylinders is suggested to increase wear and tear resistance.
CONTINUOUS HIGH SPEED DUTY
In case of continuous high speed duty, it is suggested to mount a central reinforced bearing on motor shaft, please contact our Technical Department.
MINIMUM SPEED
Standard minimum speed is about 0.5 to 3 rpm (depending on motor displacement). If you need less speed, it is possible to modify some parts of the distributor.
FLUSHING
In the need of Flushing, a 2nd drain hole is available upon request. When flushing is not available, it is possible to create an inner motor drain to help cooling.
COOLING FLOW
If the motor operates in the Intermittent Power zone, it may require a cooling flow of 20 l/min (5 gpm) to keep a drain flow viscosity of 40 cSt minimum.
FILTRATION
Hydraulic systems oil must always be filtered. The choice of filtration grade derives from needs of service life and money spent. In order to obtain stated service life it is important to follow our recommendations concerning filtration grade. When choosing the filter it is important to consider the amount of dirt particles that filter can absorb and still operate satisfactorily. For that reason we recommend filters showing when you need to substitute filtering cartridge.
• 25 μm filtration required in most applications
• 10 μm filtration in closed circuit applications
OXIDATION
Hydraulic oil oxidizes with time of use and temperature. Oxidation causes changes in colour and smell, acidity increase or sludge formation in the tank. Oxidation rate increases rapidly at surface temperatures above 60°C, in these situations oil should be checked more often. The oxidation process increases the acidity of the fluid; the acidity is stated in terms of the "neutralization number". Oxidation is usually slow at the beginning and then it increases rapidly. A sharp increase (by a factor of 2 to 3) in neutralization number between inspections shows that oil has oxidized too much and should be replaced immediately.
WATER CONTENT
Oil contamination by water can be detected by sampling from the bottom of the tank. Most hydraulic oils repel the water,
which then collects at the bottom of the tank. This water must be drained off at regular intervals. Certain types of transmission oils and engine oils emulsify the water; this can be detected by coatings on filter cartridges or a change in the color of the oil. In such cases, obtain your oil supplier advice.
DEGREE OF CONTAMINATION
Heavy contamination of the oil causes wear rising in hydraulic system components. Contamination causes must be immediately investigated and remedied.
ANALYSIS
It is recommended oil being analyzed every 6 months. The analysis should cover viscosity, oxidation, water content, additives and contamination. Most oil suppliers are equipped to analyze oil state and to recommend appropriate action. Oil must be immediately replaced if the analysis shows that it is exhausted.
