Factory&FAQ
PV Series Pump& MF Series Motor 20/21/22/23/24/25/26/27 are typically packaged securely to prevent damage during transit. The packaging includes:
Protective Wrapping: To safeguard the pump from environmental damage.
Custom Crates: For larger, heavier pumps, ensuring safe handling.
Documentation: Includes installation, maintenance instructions, and warranty details.
Delivery time depends on the model, customizations, and location but typically ranges from 2 to 6 weeks from the order date.
1. What is the PV Series Pump& MF Series Motor 20/21/22/23/24/25/26/27 ?
They belong to Sauer Danfoss Series 20 closed-circuit swashplate axial piston assemblies. PV is variable displacement pump while MF is fixed displacement motor. The codes 20 to 27 stand for different displacement specifications. Equipped with built-in charge pump, these units are engineered for hydrostatic transmission of mobile machinery and commonly applied on concrete mixer trucks and other off-road equipment.
2. What makes the PV Series Pump& MF Series Motor 20/21/22/23/24/25/26/27 ?
Integrated charge pump simplifies closed-loop hydraulic system layout.
Heavy-duty bearings provide strong resistance to harsh working conditions.
It supports stepless speed regulation and reversible rotation smoothly.
Compact structure facilitates installation and daily maintenance.
High interchangeability for original Sauer Danfoss Series 20 components.
3. What is the working pressure range of PV Series Pump& MF Series Motor 20/21/22/23/24/25/26/27 ?
Normal long-term recommended operating pressure: 50 ~ 180 bar
Continuous rated working pressure: 210 bar (3045 PSI)
Intermittent peak pressure: 350 bar (5075 PSI)
Peak pressure is only permitted for short-term impact loads
Long-duration operation under peak pressure is forbidden
4. Can PV Series Pump& MF Series Motor 20/21/22/23/24/25/26/27 replace other brands?
Direct interchangeable with original Sauer Danfoss Series 20 hydraulic units.
It can be used as performance alternative for similar closed-circuit piston sets of other brands.
Confirm displacement, shaft type, mounting flange and control mode before replacement.
Minor pipeline modification may be required for non-original equipment.
Send full model code for accurate compatibility verification.
5. What is the typical speed range of PV Series Pump& MF Series Motor 20/21/22/23/24/25/26/27 ?
Rated standard operating speed: 1500 rpm
Minimum stable operating speed: 500 rpm
Maximum allowable speed varies according to different displacement sizes
Larger displacement models have lower maximum continuous speed
Excessive rotating speed will accelerate wear and shorten service life
