Kawasaki K3V112DTP-9Y14 hydraulic pump for Sumitomo SH210-5 midi excavator
If you decide to buy equipment at a low price, make sure that you communicate with the real seller. Find out as much information about the owner of the equipment as possible. One way of cheating is to represent yourself as a real company. In case of suspicion, inform us about this for additional control, through the feedback form.
Before you decide to make a purchase, carefully review several sales offers to understand the average cost of your chosen equipment. If the price of the offer you like is much lower than similar offers, think about it. A significant price difference may indicate hidden defects or an attempt by the seller to commit fraudulent acts.
Do not buy products which price is too different from the average price for similar equipment.
Do not give consent to dubious pledges and prepaid goods. In case of doubt, do not be afraid to clarify details, ask for additional photographs and documents for equipment, check the authenticity of documents, ask questions.
The most common type of fraud. Unfair sellers may request a certain amount of advance payment to “book” your right to purchase equipment. Thus, fraudsters can collect a large amount and disappear, no longer get in touch.
- Transfer of prepayment to the card
- Do not make an advance payment without paperwork confirming the process of transferring money, if during the communication the seller is in doubt.
- Transfer to the “Trustee” account
- Such a request should be alarming, most likely you are communicating with a fraudster.
- Transfer to a company account with a similar name
- Be careful, fraudsters may disguise themselves as well-known companies, making minor changes to the name. Do not transfer funds if the company name is in doubt.
- Substitution of own details in the invoice of a real company
- Before making a transfer, make sure that the specified details are correct, and whether they relate to the specified company.

Product Brief
This OEM‑spec K3V112DTP‑9Y14 variable axial piston main pump delivers core hydraulic power for Sumitomo SH210‑5 medium‑size crawler excavator. It transforms engine torque into adjustable high‑pressure hydraulic flow to support heavy‑duty site assignments including quarry excavation, soil loading, foundation trenching and multi‑function combined operation. This OEM‑level replacement assembly gains wide recognition among overseas machinery service centers, rental business owners and cross‑border spare‑part traders for worn‑out original pump swap and complete hydraulic system refurbishment.
Under long‑term dusty construction conditions with frequent alternating load and impact shock, the original pump will suffer cylinder block galling, piston shoe abrasion and valve plate scratching. Typical failure manifestations include insufficient digging torque, drifting boom under static load, sluggish cylinder response, deteriorated traveling performance, sustained high hydraulic oil temperature, distinct pump whistling noise and obvious pressure drop under heavy‑load digging. Unexpected pump breakdown will interrupt construction schedules and bring extra emergency repair costs for project contractors.
Our OEM‑replacement pump strictly follows original equipment dimensional benchmarks for mounting interface, input shaft spline, regulator mounting position and system pressure setting. No cutting, drilling or extra adapter modification is required during field installation, greatly shortening machine idle downtime. As a practical substitute for high‑priced original assemblies with long lead‑times, this pump maintains stable hydraulic output and satisfies bulk‑order procurement demands for global Sumitomo excavator spare‑part suppliers.
Unique Product Competitive Advantages
1. Full dimensional interchangeability matching SH210‑5 original hydraulic system
Manufactured strictly referencing OEM drawing specifications, this main pump keeps consistent shaft spline parameters, oil port layout and regulator assembly dimension. High‑precision lapped friction assemblies effectively cut internal leakage after assembly. No secondary machining work is needed for on‑site replacement, helping service technicians finish pump swap efficiently.
2. Upgraded friction‑pair processing for harsh cyclic‑load construction scenarios
Many low‑cost alternative pumps suffer fast performance attenuation under frequent rock‑digging impact load. Our core internal components adopt carburizing quenching plus multi‑stage fine‑grinding craft to enhance wear resistance under alternating heavy shock load, helping fleet operators lower pump replacement frequency for heavily‑utilized SH210‑5 machines.
3. Comprehensive bench performance testing before delivery to prevent sudden on‑site failure
Each finished hydraulic pump undergoes pressure endurance test, flow‑rate calibration and sealing leakage inspection on dedicated hydraulic test bench before packing. Defective units are screened out at factory side, cutting re‑work pressure for maintenance teams and avoiding unplanned job‑site downtime losses.
4. Cost‑effective OEM‑grade solution for medium excavator maintenance budget management
Genuine OEM pumps for SH210‑5 carry high purchase cost and long delivery cycle. Our factory‑direct OEM‑replacement pump delivers dependable operating stability and full‑system compatibility, reducing annual overhaul expenditure for customers managing multiple Sumitomo excavator fleets.
5. Diversified global logistics support for wholesale buyers
In‑stock goods support quick shipment after payment confirmation. Air freight is available for urgent on‑site breakdown repair orders; consolidated sea freight and full‑container solutions bring cost‑saving options for long‑term bulk importers.
Factory Production Strength
Our production facility devotes to R&D and mass‑manufacturing of OEM‑replacement hydraulic main pumps, travel gearboxes and swing motors covering mainstream Japanese‑brand excavator models. We own complete production workflows: alloy‑steel forging, precision grinding, professional heat‑treatment and finished‑product hydraulic bench test. Dedicated simulation test equipment reproduces real‑world variable heavy‑load working status of medium‑size excavators to verify component durability. Our hydraulic spare parts are exported to multiple overseas regions and maintain long‑term stable cooperation with global construction‑machinery spare‑part wholesalers.
Frequently Asked Customer Questions
Q1: Can this K3V112DTP‑9Y14 main pump fit other Sumitomo excavator models besides SH210‑5?
A1: Cross‑model fitment is not recommended. Different main pumps vary in shaft spline, regulator parameters and pressure calibration values. Please double‑verify your machine model and original part number before submitting orders.
Q2: What hydraulic malfunctions can this main pump resolve?
A2: It fixes faults triggered by worn pistons, scratched valve plate and damaged inner assemblies: weak digging power, boom drifting, sluggish cylinder movements, high hydraulic oil temperature, internal leakage and abnormal whistling or knocking noise generated by main pump.
Q3: Am I eligible for quantity‑based discount for bulk‑quantity orders?
A3: Yes, tiered favorable pricing is offered subject to purchase volume. Full‑container sea shipment can be arranged to lower comprehensive logistics expenses.
Q4: What packaging solution is adopted for long‑distance overseas shipment?
A4: Anti‑rust grease is evenly applied on all metal surfaces. The whole pump is wrapped with waterproof shock‑absorbing PE film, then secured inside reinforced export‑grade plywood case to avoid collision deformation and moisture corrosion during long‑haul ocean transit.
