Product Information

AZPG Hydraulic Gear Pump Overview

The AZPG Hydraulic Gear Pump from Olive Branch Hydraulics is engineered as a direct, dimensionally interchangeable replacement for the Rexroth AZPG series, delivering continuous operating pressures up to 250 bar and intermittent peaks of 280 bar. Built for procurement teams that cannot afford field failures, every AZPG unit leaves our factory only after 100% pressure-bench testing, flow verification, and leak inspection — no exceptions.

As a factory-direct AZPG high pressure gear pump supplier, we serve OEMs and distributors across Europe, North America, the Middle East, and Southeast Asia with wholesale pricing, ISO 9001-certified production, and stable 15–35 day lead times. The standard AZPG series spans 22.5–100 cm³/rev; confirm the full model code for each order, giving buyers a single-source solution for construction machinery, agricultural equipment, industrial presses, and mobile hydraulic systems.

What separates our AZPG pumps in the tender process is not marketing — it is measurable performance: volumetric efficiency ≥ 94%, cast iron housing hardness HB 200–240, and gear tooth surface finish held to Ra 0.4 μm through in-house honing and grinding. Combined with SAE-standard mounting flanges and custom P/T port configurations, the AZPG pump drops into existing systems without redesign, protecting your customers' timelines and your margins.

Key Features & Buyer Benefits

Every specification of the AZPG gear pump is tied to a commercial outcome your buyers care about. Below is the direct feature-to-benefit mapping we present to procurement teams during technical qualification.

  • High-strength cast iron housing (HT250): Withstands sustained 250 bar operation and thermal cycling — translates into lower warranty claims and longer MTBF in end-user fleets.
  • Precision-ground gear pairs (Ra 0.4 μm): Volumetric efficiency ≥ 94% means less energy loss, cooler oil, and reduced cooling system load for your OEM customers.
  • Rexroth AZPG dimensional interchangeability: As a drop-in Rexroth AZPG replacement gear pump, no bracket redesign or hose rerouting — cuts integration cost by up to 40%.
  • SAE-standard flange and shaft options: Splined, keyed, and tapered shafts available; P/T ports configurable per drawing — one supplier covers multiple platforms.
  • Factory-direct pricing model: No trading company markup. Wholesale buyers typically see 20–35% cost savings versus European brand equivalents at equivalent performance.
  • 10+ years of hydraulic manufacturing experience: Predictable quality, documented process control, and English-speaking technical support reduce sourcing risk.
  • 100% pre-shipment testing: Every pump ships with a serialized test report — protecting your reputation with end customers.

All AZPG pumps use HLP/HM mineral hydraulic oil with recommended ISO cleanliness of 20/18/15 or better. Bi-directional rotation, tandem configurations, and integrated relief valves are available on request. Full CAD drawings (2D/3D STEP) are released after NDA signing.

Typical Applications & Industry Fit

The AZPG series is deployed by OEMs and MRO distributors across a wide range of high-duty-cycle applications where pressure stability and continuous service life are non-negotiable.

  • Construction machinery: Wheel loaders, mini excavators, skid steers, backhoes — as main or auxiliary pumps in open-circuit systems.
  • Agricultural equipment: Tractor hydraulics, sprayers, harvesters, and PTO-driven implement circuits requiring reliable 200+ bar output.
  • Industrial hydraulic power units (HPU): Presses, injection molding machines, metal forming, and machine tool auxiliary systems.
  • Municipal and specialty vehicles: Refuse trucks, aerial platforms, sweepers, and truck-mounted cranes.
  • Material handling: Forklifts, telehandlers, and stackers where duty cycles demand high volumetric efficiency.
  • Mobile & marine hydraulics: Deck machinery, winches, and steering assist systems tolerant of variable viscosity conditions.

Buyers in the EU, North America, GCC, and ASEAN markets consistently specify the AZPG as a Rexroth cross-reference for aftermarket and OEM builds. If you supply into any of these verticals, our engineering team can confirm compatibility against your existing part numbers within 24 hours.

OEM Customization & Compatibility Options

Olive Branch Hydraulics operates as a dedicated AZPG hydraulic gear pump OEM manufacturer. Approximately 60% of our AZPG output ships under private label or with customer-specified modifications. Our OEM program is structured for procurement teams that need predictable engineering support, not ad-hoc responses.

Customization scope

  • Displacement: Any value from 4 cc/rev to 200 cc/rev, including non-standard steps.
  • Shaft end: Splined (SAE 9T, 11T, 13T, 14T, 15T), keyed parallel, tapered 1:8, or custom per drawing.
  • Ports: SAE flange, BSP, NPT, or metric threaded; P/T positions rotatable in 90° increments.
  • Rotation: Clockwise, counter-clockwise, or bi-directional variants.
  • Configuration: Single, tandem (2P), triple (3P), or with integrated pressure relief.
  • Branding: Laser engraving, custom nameplates, private-label paint (RAL codes).

OEM workflow

  1. Submit drawing, sample, or Rexroth AZPG part number for cross-reference.
  2. Receive technical proposal and quotation within 48 working hours.
  3. Sample production: 15–20 days after drawing approval and 30% deposit.
  4. Sample validation on your test bench or ours (video reports provided).
  5. Mass production release after written PPAP-style approval.

Sample MOQ is typically 1–2 units. Tooling for fully custom housings may require a one-time fee, refundable against subsequent orders above agreed volumes.

MOQ, Lead Time & Factory-Direct Pricing

Transparent commercial terms are a core reason procurement teams migrate to Olive Branch Hydraulics as their industrial AZPG gear pump wholesale partner. The table below reflects our standard commitments for AZPG orders.

Order Type MOQ Lead Time Payment Terms
Sample order 1 unit 7–15 days 100% T/T in advance
Standard stock model 10 units 15–20 days 30% deposit / 70% before shipment
OEM customized 50 units 25–35 days 30% deposit / 70% against BL copy
Annual contract (500+ units) Negotiable Rolling forecast L/C at sight or open account

Because we control gear machining, housing casting, honing, and assembly in-house, we typically quote 20–35% below equivalent European-branded AZPG pumps at matched performance specifications. Volume tiers begin at 100, 300, and 500 units per shipment. Ex-works, FOB (Ningbo/Shanghai), CIF, and DDP incoterms are all supported.

100% Pre-Shipment Quality Control Process

Quality control is not a checkpoint — it is embedded in every stage of AZPG production. Our ISO 9001-certified system enforces documented inspection at three critical stages, with serialized traceability on every pump.

Incoming material control (IQC)

  • Chemical composition analysis of every cast iron and steel batch via in-house spectrometer.
  • Hardness testing (HB/HRC) on housings, gears, and shafts.
  • Dimensional verification of critical components using CMM equipment.

In-process quality control (IPQC)

  • Gear tooth profile and surface roughness inspection after honing and grinding.
  • Bore concentricity and parallelism checks post-boring.
  • Torque-controlled assembly on automated lines with digital record capture.

Final pre-shipment testing (OQC)

  • 100% pressure bench test at rated and peak pressure.
  • Flow rate verification against nameplate specification (±3% tolerance).
  • Internal and external leak detection under load.
  • Noise level check (< 78 dB(A) at 1 m, standard operating conditions).
  • Serialized test report issued and archived for 5 years.

No exceptions. Every AZPG pump that enters the packing area has a matching digital test record tied to its serial number, available to buyers on request.

Packaging & Shipping

Standard export packaging is designed to survive multi-modal transport to Europe, North America, the Middle East, and Southeast Asia without corrosion or impact damage.

  • Individual protection: Ports sealed with plastic plugs, exposed metal coated with anti-rust oil, VCI film wrap.
  • Inner box: Foam-cushioned carton with product label, serial number, and QC certificate.
  • Outer packaging: Reinforced export carton or fumigation-free plywood case, palletized and strapped.
  • Custom marking: Shipping marks, barcodes, and country-of-origin labels per buyer specification.

We work with buyer-nominated forwarders or offer our own consolidated logistics with DDP delivery to major EU, US, GCC, and ASEAN ports. Typical transit times: 25–35 days to EU/US main ports, 15–20 days to Middle East, 10–15 days to Southeast Asia.

Procurement FAQs: Pricing, Delivery & Compatibility

1. Are your AZPG pumps 100% interchangeable with Rexroth AZPG originals?

Yes. Mounting flange, shaft dimensions, port positions, and overall envelope are matched to the Rexroth AZPG specification. In field replacements, no bracket or hose modification is required. Provide us the exact Rexroth part number and we will confirm cross-reference in writing.

2. What is the minimum order quantity and can we start with samples?

Sample MOQ is 1 unit for standard displacements. Standard production MOQ is 10 units. For OEM-customized pumps with private labeling or non-standard shafts, MOQ is 50 units. We encourage sample validation before committing to bulk purchase orders.

3. How competitive is your pricing versus European brands?

Because we are the manufacturer — not a trader — factory-direct pricing typically runs 20–35% below equivalent European-branded AZPG pumps at matched performance. Volume discounts apply from 100 units per shipment. Request a quote with your target annual volume for tiered pricing.

4. What warranty and after-sales support do you offer?

Standard warranty is 12 months from shipment or 2,000 operating hours, whichever comes first, against manufacturing defects. Warranty claims are processed within 5 working days with replacement parts or credit notes. We provide English-language technical support and CAD drawings under NDA.

5. Can you handle urgent replenishment orders?

Common AZPG displacements (22, 45, 90 cc/rev) are held in semi-finished stock, allowing 7–10 day dispatch for orders up to 50 units. Air freight and express courier options are available for critical field-service scenarios. Notify us in advance to reserve stock allocation for your account.
