| 4535VA Series 4535VA-66A38-86AA22R Hydraulic Double Vane Pump |
|
| This double vane pump delivers stable flow output under fluctuating working pressure conditions. | |
| Balanced pressure structure minimizes side force on the shaft to extend bearing lifespan. | |
| Compatible with multiple types of hydraulic oil for diverse operating environment requirements. | |
| Flexible mounting layout adapts well to different installation spaces of industrial machinery. | |
| Robust cast iron housing offers good resistance to mechanical shock and heavy load impacts. | |
| Precision machined vane assembly maintains low internal leakage for long service cycles. | |
| Optimized internal runner design reduces fluid turbulence and energy loss during continuous operation. |

3. Core Advantages
Balanced vane structure offsets radial hydraulic force on rotor and shaft, reducing bearing load and extending service cycle.
Low flow pulsation and quiet running operation, suitable for equipment requiring low vibration and stable working environment.
Dual output design allows two hydraulic circuits to run independently. One circuit for heavy load actuation, another for auxiliary control or lubrication.
Floating side plate structure automatically compensates clearance caused by wear, maintaining high volumetric efficiency over long operating hours.
Modular pump cartridge design cuts downtime for overhaul, spare parts stocking becomes easier.
Compact overall dimension, easy to fit into tight machine power unit space.
4. Application Scenarios
This tandem vane pump fits machinery that requires two independent hydraulic oil supplies.
Plastic injection molding machines: supply high-pressure flow for mold clamping and low-pressure flow for material feeding and ejector action separately.
Die casting equipment: drive mold locking mechanism and auxiliary hydraulic core pulling circuit at the same time.
Metal stamping and hydraulic press: provide main power for press cylinder and control oil for valve group and clamping fixture.
Industrial hydraulic power stations for factory automation, dual loop conveyor and clamping systems.
Light-duty marine hydraulic equipment, such as hatch cover and deck auxiliary actuator systems.
Paper making and textile machinery, for roller tension control and material cutting hydraulic drive.
