Commercial Hydraulic Gear Pump Models & Applications
Hydraulic gear pumps convert mechanical input into hydraulic flow. This catalogue explains the function of each listed configuration and typical use cases; it does not claim every model suits every machine. Contact 95 Services with the pump nameplate and equipment details to assess replacement compatibility.
Technical note: P31, P51 and P76 belong to bearing-supported series; P315 and P330 are bushing-supported series. Exact flow, working pressure, rotation and fittings vary by full part number.
P330 Series Double Gear Pump
A tandem, bushing-supported gear pump arrangement for equipment that needs two hydraulic pumping sections driven from one input.
Typical applications
- Construction and material-handling machines with main and auxiliary hydraulic functions
- Industrial power packs that require two separately sized pump sections
- Mobile machinery where combined pump packaging may simplify installation
Confirm displacement for each section, tandem configuration, drive torque, shaft, mounting flange, ports and rotation. Do not assume both sections have identical output.
P330 Series Single Gear Pump
A single-section bushing-supported external gear pump for delivering hydraulic flow to one suitably designed circuit.
Typical applications
- Industrial hydraulic power units and fixed equipment
- Construction machinery auxiliary hydraulic systems
- Replacement of matching P330-type pumps in mobile systems
Match the complete part number, displacement, shaft, flange, port configuration, rotation and application pressure requirements.
P315 Series Double Gear Pump
A dual-section version of the P315 bushing-type family, useful where a machine needs two pumping functions in one integrated assembly.
Typical applications
- Compact hydraulic power systems with separate equipment functions
- Agricultural and industrial auxiliary circuits
- Replacement installations where the original uses a P315 tandem configuration
Check both gear-section displacements and their sequence, overall length, pump drive rating, ports and exact mounting arrangement.
P76 Series Double Gear Pump
A tandem external gear pump from the larger P76 bearing-supported family, intended for appropriately engineered higher-flow equipment arrangements.
Typical applications
- Heavy-duty material-handling and mobile hydraulic equipment
- Lifting or tipping machinery with multiple hydraulic demands
- Industrial systems already configured for a P76 tandem pump
Verify the machine load profile, both section sizes, shaft-drive capacity, relief settings, mounting and inlet line requirements.
P51 Series Double Gear Pump
A two-section bearing-supported gear pump configuration for applications with more than one hydraulic function.
Typical applications
- Agricultural machinery with primary and auxiliary circuits
- Mobile lifting and material-handling equipment
- Multi-function industrial power packs
Identify the exact tandem build, displacement of each stage, rotation, flange and ports before choosing a replacement.
P51 Series Single Gear Pump
A single-section P51 bearing-supported gear pump for conventional hydraulic power delivery in a compatible circuit.
Typical applications
- General industrial hydraulic machinery
- Mobile equipment with a dedicated pump circuit
- Replacement of an existing P51-series unit where dimensions and duty match
Confirm displacement, continuous-duty requirements, inlet conditions, rotation, drive shaft and connection sizes.
P31 Series Double Gear Pump
A compact tandem arrangement in the P31 bearing-supported family for equipment that combines two hydraulic pumping sections.
Typical applications
- Smaller mobile machinery with dual hydraulic functions
- Compact hydraulic power-unit assemblies
- Existing P31 tandem installations needing a matched replacement
Check total assembly length, section displacements, shaft and mounting geometry, port positions and drive suitability.
P31 Series Single Gear Pump
A single-section external gear pump from the P31 bearing-supported range, often considered for compact hydraulic systems.
Typical applications
- Compact hydraulic power packs
- Smaller agricultural or service machinery hydraulic circuits
- Like-for-like replacement where an original P31 specification is available
Confirm the exact model code and compatible displacement, mounting, shaft, port thread and rotation before ordering.
Single vs Double Hydraulic Gear Pumps
The correct arrangement depends on the hydraulic circuit design and the machinery manufacturer's requirements. A double pump is not a plug-in replacement for a single pump without engineering checks.
Single Gear Pump
One pumping section provides flow to a suitably configured hydraulic circuit. A single unit may be preferable when the equipment needs one pumping source and the original installation has one pump section.
- One pump section and displacement specification
- Often used for conventional power packs and machine circuits
- Match rotation, inlet/outlet ports, shaft and mounting
Double / Tandem Gear Pump
Two pumping sections share a driven assembly and can provide flow for distinct hydraulic functions when the circuit is designed for them. Section displacements and flow demands may differ.
- Two section sizes and connection details must be verified
- Useful in selected multi-function mobile or industrial systems
- Check total input torque, suction supply and drive suitability
Compare Pump Families Before You Enquire
These are broad distinctions to guide the initial enquiry, not certified performance ratings. A specific pump's datasheet and complete model number take priority.
| Series | Support design | Listed configurations | Typical evaluation point |
|---|---|---|---|
| P330 | Bushing-supported | Single / Double | Check displacement, mounting and tandem drive design |
| P315 | Bushing-supported | Double | Check compact tandem arrangement and stage sizes |
| P76 | Bearing-supported | Double | Review higher-flow application needs and drive loading |
| P51 | Bearing-supported | Single / Double | Check general machinery duty and pump-section layout |
| P31 | Bearing-supported | Single / Double | Check compact power-unit fit, shaft and ports |
What to Send for Hydraulic Pump Matching
A clear pump identification request is more useful than a series name alone. Share as much of the following as you can; our team can review the enquiry and advise the next step.
Safety: hydraulic systems can hold residual pressure even after shutdown. Identification, removal and replacement should follow the machine manufacturer's service and isolation procedures.
Hydraulic Gear Pump FAQs
What is the difference between a single and double gear pump?
A single gear pump has one pumping section. A double, or tandem, pump contains two sections in one driven assembly. It can support multiple machine functions where the hydraulic system and shaft drive are designed for that arrangement.
Can I replace a P51 pump with a P31 or P76 pump?
Not by series name alone. The complete model code, displacement, mounting dimensions, shaft, port layout, rotation and allowed duty must match the equipment requirements. Engineering assessment is necessary before substituting a different series.
What is the difference between P330 and P315 series?
Both are associated with bushing-supported gear pump designs, but they represent different series and possible displacement and mounting configurations. Confirm the manufacturer's detailed technical data before choosing one for a machine.
Which pump should I use for a hydraulic power pack?
Start with the required flow at operating RPM, working pressure, oil type, duty cycle, available drive power and the system's valve and relief arrangement. Then verify a specific pump configuration against the power-pack design.
Why is the pump noisy or losing performance?
Potential causes include insufficient oil supply, restricted inlet lines, cavitation, aeration, contaminated fluid, internal wear or an incorrectly configured relief circuit. Diagnosis is needed before selecting replacement parts.
Are these specific pumps in stock and what do they cost?
Availability, lead time and price depend on the exact part number and supplier confirmation. Contact 95 Services with the model plate, required quantity and delivery location to request a quotation.
Can you help with a hydraulic pump repair enquiry in Dubai?
You can contact 95 Services about hydraulic pumps and associated industrial troubleshooting. The next step, whether inspection, repair assessment or a replacement enquiry, depends on the machine symptoms and component condition.
