Factory&FAQ
A10V Pump A10V(S)O31/32/52&53 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 A10V Pump A10V(S)O31/32/52&53 ?
The 31 version is the classic mature model with complete displacement specifications; the 32 version improves noise reduction and working efficiency while keeping interchangeable installation dimensions.
The 52 and 53 versions are small-displacement pumps (10cc only), where 53 upgrades the sealing material for better resistance to high temperature and deteriorated hydraulic oil.
Multiple control modes (DR, DFR, DFLR, ED) are optional, widely matched for construction machinery and industrial hydraulic systems.
2. What makes the A10V Pump A10V(S)O31/32/52&53 ?
The 31 & 32 main series use high-strength cast iron housings to bear high system pressure, equipped with multi-type integrated control valves for automatic load adjustment and energy saving.
The 52 and 53 small-displacement models feature compact layout; the 53 model is fitted with FKM fluororubber seals to adapt to harsh oil and temperature conditions.
Double drain ports, load-resistant input shaft and standardized SAE mounting structure jointly guarantee stable operation, strong durability and universal replaceability for construction machinery and industrial hydraulic equipment.
3. What is the working pressure range of A10V Pump A10V(S)O31/32/52&53 ?
Continuous rated pressure: 280 bar = 4061.06 psi
Instantaneous peak pressure: 350 bar = 5076.33 psi
All versions (31/32/52/53) share this unified pressure parameter standard.
4. Can Hydraulic A10V Pump A10V(S)O31/32/52&53 replace other brands?
Original standard benchmark: It is designed strictly following the dimensional drawing of Rexroth A10VSO series. The mounting flange, input shaft size, oil port position, control valve interface and installation overall dimension are fully consistent with original Rexroth pumps, which can be directly installed without modifying equipment structures.
Inter-brand substitution: Most domestic peer brands that copy Rexroth A10VSO structure share unified external dimensions, so this pump is interchangeable with those generic A10VSO pumps from different manufacturers.
Precondition for replacement: Match the exact series code (31/32/52/53), displacement value, control type (DR/DFR/DFLR/ED) and rotation direction before replacement.
Pressure parameter consistency: Rated pressure 280 bar (4061.06 psi), peak pressure 350 bar (5076.33 psi), consistent with original design pressure, meeting the original system working requirements.
5. What is the typical speed range of A10V Pump A10V(S)O31/32/52&53 ?
The standard allowable operating speed range for the A10V(S)O 31/32/52&53 pump series is 500 rpm to 3000 rpm.Stable working performance can be maintained within this whole speed interval under rated working pressure.
6. Do you provide OEM or customized services?
OEM service: We can print your brand logo, label, company part number on the pump housing and nameplate; neutral packaging or branded packaging is available as requested.
Customized items: Customize control modes, rotation direction, shaft specifications, seal materials (FKM/NBR), paint color and outer appearance. We also accept customized flow and pressure parameters for special working conditions.
Custom drawings and samples can be developed according to your technical requirements for long-term matching use.
