K3V112 Gear Pump

Each unit combines a tandem twin-pump architecture with an integrated pilot gear pump, delivering a rated flow of 2 × 112 cc/rev and continuous working pressure up to 32 MPa. All critical components — cylinder block, valve plate, piston shoes, and swashplate — are produced on precision machining centers and finished through dedicated honing and grinding processes to guarantee dimensional interchangeability with original Kawasaki K3V112DT castings.

For procurement managers sourcing K3V112 excavator main pump OEM solutions in bulk, our factory-direct model eliminates trading margins, shortens lead times to 15 to 25 days for standard configurations, and supports white-label branding for aftermarket distributors across Europe, North America, the Middle East, and Southeast Asia.

Key Features & Benefits

The K3V112 platform is optimized to solve the two problems that matter most to bulk buyers: service life under real jobsite loads and inventory-ready interchangeability. Every design and manufacturing decision maps to a measurable procurement benefit.

• Bimetal Cylinder Block & Nitrided Valve Plate — Extended service life beyond 8,000 operating hours under standard duty cycles, reducing warranty claims and end-user downtime for your aftermarket customers.
• Full Kawasaki K3V112DT Cross-Compatibility — Mounting flange, spline shaft (Z=13, module 2.5), port geometry, and regulator interface match OEM dimensions, so your customers install with zero adapter kits or field rework.
• Integrated Pilot Gear Pump (10 cc/rev) — Single-unit sourcing for both main and pilot circuits cuts your SKU count and simplifies aftermarket kitting.
• Electric & Hydraulic Regulator Options — Supports negative flow control (NFC), positive flow control (PFC), and load-sensing variants, letting one warehouse SKU cover multiple excavator brands.
• 100% Pre-Shipment Pressure & Flow Bench Testing — Every pump is tested at 32 MPa with certified flow meters and leak detectors. Test reports ship with each unit for QC traceability.
• OEM & White-Label Packaging — Custom nameplates, laser-etched serials, branded cartons, and multilingual manuals available from 50-unit MOQ.
• Bulk Pricing Tiers — Volume breakpoints at 10, 50, 100, and 500 units, with FOB Tianjin or CIF destination-port quotations locked for 30 days.

The commercial outcome for distributors: a landed cost typically 55 to 70 percent below genuine Kawasaki pricing, with a failure-return rate held below 0.8 percent across the last 24 months of shipment data.

Why Choose Us

Olive Branch Hydraulics operates as a dedicated hydraulic component manufacturer, not a trading intermediary. Our Hebei facility has produced piston pumps, gear pumps, cycloidal motors, and valve assemblies for more than 10 years, serving OEM and aftermarket clients across 40+ countries.

What that means for a procurement manager evaluating a new Kawasaki K3V112 replacement pump wholesale source:

• Verifiable Manufacturing Base — In-house precision machining centers, automated assembly lines, and dedicated honing, boring, and grinding equipment. Factory audit visits and third-party inspections (SGS, BV, TÜV) are welcomed and pre-arranged within 5 business days.
• ISO 9001 Quality System — Every K3V112 unit is manufactured to ISO 9001 documented procedures, with material certificates, hardness tests, and dimensional inspection records archived per serial number.
• 100% Pre-Shipment Testing, No Exceptions — Our in-house testing center runs pressure benches, flow meters, leak detectors, and material analyzers on every pump before packing. Test data is included in the shipping documentation.
• Predictable Lead Time & Stock Buffer — Standard K3V112DT configurations ship in 15 to 25 days. Rolling safety stock covers urgent replenishment for contracted distributors.
• OEM & Private-Label Program — Custom castings, nameplates, part-number engraving, and branded packaging are supported from low MOQ, giving distributors a defensible in-house product line.

The result is a supply relationship built on documented quality, transparent pricing, and factory accountability, not a rebranded trading channel.

FAQ

1. What is the minimum order quantity for the K3V112 gear pump, and how does bulk pricing work?

MOQ is 1 unit for sample orders and 10 units for standard commercial orders. Volume tiers apply at 10, 50, 100, and 500 units, with discounts increasing at each breakpoint. For distributors committing to annual volume, we issue a locked price agreement with quarterly release schedules to stabilize your landed cost against raw material fluctuations.

2. Is your K3V112 pump fully interchangeable with the original Kawasaki K3V112DT?

Yes. Mounting flange, spline shaft dimensions, port positions, regulator interface, and overall envelope match Kawasaki K3V112DT specifications. Installation on Hyundai R210, Doosan DH220, Kobelco SK200, and Volvo EC210 excavators requires no adapters or field modifications. We can provide a dimensional drawing for cross-verification before your PO.

3. What is the standard lead time for bulk orders?

15 to 25 working days for standard configurations up to 100 units. Orders above 100 units are scheduled in production batches, typically 30 to 45 days. Rush production is available for contracted partners with a 20 percent premium.

4. Do you support OEM branding and custom packaging?

Yes. We offer full white-label service including custom nameplates, laser-etched serial numbers, branded cartons, multilingual installation manuals, and custom color coding. OEM branding is available from a 50-unit MOQ per SKU.

5. What warranty and after-sales support do you provide?

Standard warranty is 12 months from shipment date or 2,000 operating hours, whichever comes first, covering manufacturing defects. Each unit ships with an individual test report. For distributors, we maintain a technical support channel with 24-hour response and provide field-failure analysis on returned units within 10 business days.
