| Series | F11 Series Quantitative Pump/Motor |
Specifications | F11-005, F11-006, F11-010, F11-012, F11-014, F11-019, F12-030, F12-040, F12-060, F12-080, F12-090, F12-110, F12-125, F12-152, F12-162, F12-182, F12-250, etc | |
Work stress | Rated pressure 42MPa, peak pressure 48MPa | |
Characteristics | L installation form conforms to standard VDMA-24560l standard installation form: IS0 3019/2 4-hole flange (metric system) l optional installation form: IS0 3019/1 4-hole flange (SAE)l large variable control piston with strong return spring, fast response. L Because the compensation system has a strong pressure release effect, it reduces the pressure peak value when the flow variable is zero. L still has a stable compensation adjustment function under low T pressure: the minimum compensation pressure is 12-15barl 9 plunger design and the new pre-compression volume technology is adopted to reduce the flow pulsation to an unprecedented minimum level. the robust and FEM-optimized pump body structure reduces the noise level. the complete variable control type l 100% nominal torque through-shaft transmission structure l the same specification, the same type and almost all pumps with the same metric or SAE mounting flange can be installed in combination. |
Rotation direction
The motor is bi-directional under operating conditions.
As the pump operation is a single rotation, allowing a higher self-priming speed. Under motor conditions, when port B (black arrow) is a pressure port, the shaft rotates clockwise, and when port A (hollow arrow) is a pressure port, the shaft rotates counterclockwise.
Under the working condition of the pump, if the shaft rotates clockwise, the oil port B is the oil inlet and should be connected with the oil tank. When the shaft rotates counterclockwise, the oil port A is the oil inlet.
Hydraulic oil
The grade and performance data of the F11/F12 series are based on measurements using high-quality, non-polluting petroleum-based oils.
The system can use HLP (DIN 51524) hydraulic oil, type A automatic gearbox oil and type API CD oil.
Refractory fluids (when used under modified operating conditions) and synthetic fluids are also suitable for use.
Operating temperature
Do not exceed the following temperature (shaft seal material FPM, code V):
Main circuit: 80°C
Oil drain circuit: 115°C.
The shaft seal material NBR (code N) can withstand the oil discharge temperature of 90°C.
Note: The temperature should be measured at the drain where it is in use.
Continuous operation may require housing flushing to meet viscosity and temperature limits. The following table gives some operating speeds, above which flushing is usually required, and the corresponding recommended flow through the housing.
Viscosity
The ideal working range of oil viscosity is 15 to 30 mm2/s [cSt].
At the working temperature, the viscosity of the leaking oil should be kept above 8 mm2/s [cSt]. During startup, the oil viscosity shall not exceed 1000 mm2/s [cSt].
Filtering
In order to obtain the maximum service life of F11/F12, the oil cleanliness level shall meet or exceed ISO level 20/18/13 (ISO 4406).
Under normal operating conditions, it is recommended to use a filter with an absolute filtration accuracy of 10 μm.
Shell pressure
The service life of the shaft seal is affected by the motor speed and the oil discharge pressure of the casing. The service life of the shaft seal will be shortened when the pressure peak frequency increases.
Note that the seal life is shortened under poor operating conditions (high temperature, low oil viscosity, oil contamination).
Required inlet pressure
Under certain conditions, the motor can work as a pump. In this case, the pressure of the oil inlet cannot be lower than a minimum pressure, otherwise it may increase noise due to cavitation and cause gradual performance degradation.
If an inlet pressure of 15 bar is measured at the motor inlet, most operating conditions can be met.
