Gear pump (hydraulic/oil transfer)

Description

1. Product Overview
   Gear pump (hydraulic/oil transfer) is a precision positive-displacement pump engineered to transfer and pressurize hydraulic fluids, lubricants, and oil-based media across industrial systems. It provides continuous, pulse-minimized flow for circulation, metering, and high-pressure hydraulic operations, delivering dependable volumetric performance in demanding manufacturing, mobile equipment, and process-plant environments. Key value propositions include robust volumetric efficiency, low maintenance through hardened gear metallurgy, and stable delivery under variable viscosity and pressure conditions. Strategically, this pump reduces downtime and total cost of ownership (TCO) for large-scale fluid-handling operations, making it a critical component in OEM supply chains and aftermarket maintenance programs.

2. Key Specifications & Technical Characteristics

• Pump type: External gear pump, bi-rotational capability option available for reversible flow use.

• Materials of construction: Pump body—ductile iron (standard), stainless steel 316L (corrosion-resistant option), aluminum alloy (lightweight option); gears—hardened alloy steel (case-carburized & ground), optional stainless-steel or bronze gears for specialty fluids.

• Sealing: Mechanical seal (silicon carbide/graphite), Buna-N (standard), Viton/FKM and PTFE options for elevated temperature/chemical compatibility.

• Viscosity range: 10–5000 cSt operational range (typical), suitable for oils, hydraulic fluids, gear oils, and light bitumen at elevated temperature.

• Pressure rating: Continuous discharge up to 10–25 bar (145–362 psi) depending on model; intermittent peak ratings higher per model datasheet.

• Flow rate range: Modular models from 0.5 L/min up to 1,200 L/min (model-dependent).

• Temperature range: -20°C to +120°C standard; high-temp variants to +200°C with specialty seals.

• Directionality: Single-direction standard; reversible models available.

• Mounting & shafts: SAE/B14 flange mounts; keyed shaft, tapered or keyed with optional flexible couplings.

• Tolerances & efficiency: Precision-ground gears, volumetric efficiency typically 85–98% depending on operating conditions.

• Physical characteristics: Weight varies by model from 3 kg (compact units) to 450 kg (heavy-duty industrial units); footprint and dimensional drawings available per model.

• Ingress & protection: IP65-rated housings available for weather and splash protection.

• Packaging: Industrial wooden crate, palletized with corrosion inhibitor and desiccant; shrink-wrapped for export; custom export packaging on request.

• Documentation: Includes detailed datasheet, performance curves, installation & maintenance manual, material certificates (EN 10204/3.1 upon request), and QA inspection report.

• Shelf life & storage: Mechanical components have indefinite shelf life if stored dry and protected; recommended storage conditions: 0–40°C, <75% RH, periodic rotation of shaft for long-term storage to prevent gear-set staining.

3. Core Industrial Applications

• Primary industries: Heavy machinery OEMs, hydraulic system integrators, marine & offshore, oil & gas, power generation, steel & metal processing, pulp & paper, chemical plants, and bulk fuel transfer logistics.

• Operational use cases:

  • Hydraulic power units for construction and mining equipment, delivering stable flow under variable loads.

  • Lube oil circulation in turbines, compressors, and gearboxes where precise volumetric delivery prevents wear.

  • Fuel and oil transfer for bunkering, tank farms, and loading arms with compatibility for a wide viscosity range.

  • Metering and batching of oils and additives in process industries where repeatable volumes are required.

  • Circulation of thermal oils and heat-transfer fluids in process heating systems (with high-temp variants).

• Why it outperforms alternatives: Gear pumps offer superior volumetric accuracy versus centrifugal pumps at low flow/high viscosity conditions, simpler mechanical design than vane or piston pumps reducing maintenance complexity, and higher reliability in contaminated or particulate-laden oil due to robust gear clearances and hardened construction. This translates into lower lifecycle maintenance costs and higher uptime for industrial operations.

4. Competitive Advantages

• Quality consistency: Manufactured to ISO 9001-controlled processes, tight gear machining tolerances, and batch-tested performance curves to ensure consistent volumetric delivery.

• Supply reliability: Multi-supplier casting and machining network with regional stocking hubs enables rapid fulfillment and risk mitigation for large volume contracts.

• Logistics capability: Export-ready packaging, FCL/LCL consolidation services, global freight partnerships, and ability to load up to specified container capacities for bulk orders.

• Price competitiveness: Modular platform reduces custom-engineering overhead; volume pricing and long-term contract discounts for OEM and distributor partnerships.

• Sustainability benefits: Long service intervals reduce parts consumption; availability of repair kits and remanufacturing programs extends product life and lowers embedded carbon versus single-use replacements.

• Technical support: Dedicated application engineering, on-request hydraulic system matching, installation guidance, commissioning support, and full maintenance manuals. Traceable material certificates and performance test reports included.

5. Commercial & Supply Information

• Minimum order quantity (MOQ): BULK 20MT

• Loading capacity (MT per container): Dependent on model mix and packaging; typical examples:

  • 20-foot container (20ft GP): up to 8–12 MT of packaged medium-duty units (model-dependent).

  • 40-foot high cube (40ft HC): up to 24–28 MT of packaged medium-duty units (model-dependent).

• Lead times: Standard models 6–10 weeks; stocked items and negotiated long-term agreements can reduce lead time. (Confirm at time of RFQ.)

• Warranty & aftermarket: Standard 12-month limited warranty; extended warranty and onsite commissioning available under contract.

• Terms: FOB, CIF, or DAP available; payment and incoterm specifics to be confirmed per PO.
