š Product Overview
The REXROTH R901336056 is a PVQ52 series hydraulic vane pump identified by the full configuration code PVQ52-1X/193-040RJ15UDMC and associated reference G8050350.
It is a hydraulic vane pump intended for fluid-power systems where controlled hydraulic flow is required for machinery, mobile equipment, industrial hydraulics, and marine applications. Available product records identify the unit as manufactured in Italy and list an approximate weight of 45.5 kg.
The long Rexroth ordering code is important when matching a replacement. Two pumps from the same PVQ52 family should not automatically be considered interchangeable without checking the complete code, port arrangement, mounting configuration, displacement, and system requirements.

āļø Key Features
- PVQ52 series hydraulic vane pump
- Rexroth R901336056 identification
- Full configuration code PVQ52-1X/193-040RJ15UDMC
- Associated G8050350 reference
- Designed for industrial hydraulic applications
- Suitable for replacement and maintenance of existing hydraulic systems
- Heavy-duty construction for industrial fluid-power equipment
- Italian-manufactured unit according to available product records
- Approximate unit weight of 45.5 kg
The complete configuration code should always be used when ordering because the pump’s hydraulic and mechanical configuration is not determined by āPVQ52ā alone.
š Typical Applications
The R901336056 can be used in hydraulic systems where a vane pump is required for continuous fluid-power operation.
Typical applications include:
- Industrial hydraulic power units
- Machine tools
- Hydraulic presses
- Material-handling equipment
- Marine hydraulic systems
- Deck machinery
- Winch and lifting equipment
- Hydraulic actuators
- Industrial machinery
- Replacement of legacy Rexroth hydraulic pumps
For marine and industrial equipment, the pump should be matched to the existing hydraulic circuit rather than selected only by nominal series designation.
š Model Identification
When checking the physical pump, look for the following references:
R901336056
PVQ52-1X/193-040RJ15UDMC
G8050350
FD 454 23
M Rating 80 50 400
The R901336056 and G8050350 references are both associated with the PVQ52-1X/193-040RJ15UDMC configuration in current product documentation.
ā Frequently Asked Questions
Q1: What type of pump is R901336056?
It is a Rexroth PVQ52 series hydraulic vane pump.
Q2: What is the full Rexroth model number?
The available records identify it as PVQ52-1X/193-040RJ15UDMC.
Q3: What is G8050350?
G8050350 is an associated identification/reference number for the R901336056 pump configuration.
Q4: Where was this pump manufactured?
Available product records identify Italy as the country of origin.
Q5: How much does the pump weigh?
Current product records list approximately 45.5 kg.
Q6: Can another PVQ52 pump directly replace this model?
Not necessarily. The complete ordering code should be compared before replacement, including displacement, mounting, shaft, port configuration, and other hydraulic characteristics.
Q7: Is R901336056 a complete hydraulic pump or a replacement part?
The available listings identify it as a complete hydraulic vane pump rather than an electronic control module.

š§° Installation & Maintenance Notes
Before installing the pump, confirm the complete identification code against the original unit.
Recommended checks include:
- Verify R901336056 and G8050350 markings.
- Compare the complete PVQ52 ordering code.
- Confirm shaft and mounting dimensions.
- Check hydraulic inlet and outlet port configuration.
- Verify the hydraulic medium and fluid cleanliness requirements.
- Inspect seals and connection points before installation.
- Flush contaminated hydraulic circuits before commissioning.
- Confirm the pump rotates in the correct direction.
- Check operating pressure and flow against the machine specification.
- Monitor for abnormal noise, vibration, leakage, or excessive temperature after startup.
Because this is a hydraulic component, contamination and incorrect installation can cause premature pump failure even when the replacement model appears physically compatible.
š¦ Condition & Ordering Notes
Current commercial listings identify the R901336056 as New Other, with an approximate weight of 45.5 kg.
For ordering, the safest identification is:
REXROTH R901336056
PVQ52-1X/193-040RJ15UDMC
G8050350
Please compare the nameplate and full ordering code on the actual pump before installation. The complete configuration code should take priority over a general PVQ52 series match.
