Kawasaki K3V112DT-9C32 hydraulic pump for Sumitomo SH200A1 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 K3V112DT‑9C32 dual‑circuit axial piston main pump serves as the power source for the older‑generation Sumitomo SH200A1 20‑ton excavator hydraulic system. It converts engine rotational power into variable high‑pressure hydraulic flow, supporting earth excavation, foundation trenching, stockpile loading and multi‑function compound movements for aged construction machinery. This OEM‑replacement pump is widely purchased by overseas second‑hand equipment refurbishment yards, independent service centers and cross‑border spare‑part traders for direct pump replacement and full hydraulic system overhaul.
Working under long‑time cyclic load, oil impurity pollution and frequent pressure impact on rugged construction sites, the original pump will produce cylinder block galling, piston shoe abrasion, valve plate scratching and growing internal leakage. Typical failure behaviors include insufficient digging output, lagged combined movements, degraded traveling response, continuous hydraulic oil overheating, distinct pump vibration noise and obvious pressure drop under digging load. Sudden pump breakdown will halt site operation and bring unplanned repair costs for equipment owners running pre‑owned fleets.
Our OEM‑replacement pump strictly follows original drawing requirements for mounting flange dimension, input shaft spline, regulator installation position and factory pressure setting. No drilling, cutting or extra adapter modification is required during field fitting, greatly shortening machine idle hours. As a viable substitute for costly original units with unstable stock availability, this pump delivers consistent hydraulic performance and satisfies bulk‑order procurement for global suppliers specializing in older Sumitomo excavator spare parts.
Unique Product Competitive Advantages
1. Full dimensional compatibility matching SH200A1 original hydraulic assembly
Produced per OEM technical specifications, this main pump keeps identical shaft spline specs, oil port layout and regulator mounting dimension. Precisely machined friction pairs effectively control internal leakage after assembly. No secondary on‑site machining is needed during replacement, allowing maintenance technicians to complete pump swap efficiently for refurbished used machines.
2. Upgraded friction‑pair processing adapting to old‑machine system characteristics
Many low‑cost alternative pumps suffer rapid performance decay when matched to aged hydraulic circuits with residual contamination. Our core internal components adopt carburizing quenching plus multi‑step fine‑lapping craft to boost wear‑resistance under alternating pressure shocks, helping fleet operators reduce pump replacement frequency for heavily‑utilized SH200A1 units.
3. Complete bench performance testing before delivery to prevent jobsite sudden failure
Each finished hydraulic pump undergoes pressure endurance test, flow calibration and sealing leakage inspection on dedicated hydraulic test bench before packing. Defective assemblies are screened out at factory, lowering re‑work risks for maintenance crews and avoiding costly unplanned machine downtime on construction sites.
4. Practical OEM‑grade aftermarket solution for used‑equipment overhaul budget control
Genuine OEM main pumps for SH200A1 carry high purchase price and hard‑to‑secure supply. Our factory‑direct OEM‑replacement pump offers reliable operating stability and full system compatibility, cutting annual overhaul expenditure for customers managing fleets of second‑hand construction machinery.
5. Versatile global logistics support for wholesale buyers
In‑stock goods support quick shipment upon payment confirmation. Air freight service is available for urgent emergency repair orders; consolidated sea freight and full‑container selections provide cost‑effective options for long‑term bulk importers of vintage excavator spare parts.
Factory Production Strength
Our production facility concentrates on R&D and volume manufacturing of OEM‑replacement hydraulic main pumps, travel gearboxes and swing motors for classic Japanese‑brand excavator models. We own complete production workflows: alloy‑steel forging, precision grinding, professional heat‑treatment and finished‑product hydraulic bench validation. Specialized simulation equipment replicates real‑world variable‑load working conditions of aged 20‑ton excavators to verify component service life. Our hydraulic spare parts are exported to multiple overseas regions and maintain long‑term stable partnerships with global construction‑machinery spare‑part wholesalers focusing on older‑model equipment components.
Frequently Asked Customer Questions
Q1: Can this K3V112DT‑9C32 main pump fit other excavator models besides SH200A1?
A1: Cross‑model fitment is not advised. Different main pumps differ in shaft spline, regulator parameters and pressure calibration values. Please double‑confirm machine model and original part number before submitting orders.
Q2: What hydraulic faults can this main pump resolve?
A2: It fixes failures caused by worn pistons, scratched valve plate and damaged inner assemblies: weak digging force, sluggish compound movements, high hydraulic oil temperature, internal leakage and abnormal vibration or knocking noise from main pump.
Q3: Am I eligible for quantity‑based tiered discount for bulk‑volume orders?
A3: Yes, preferential pricing is offered subject to purchase quantity. Full‑container sea shipment can be arranged to reduce comprehensive logistics expenditure.
Q4: What packaging measure is adopted for long‑distance overseas shipment?
A4: Anti‑rust grease is evenly applied on all metal working surfaces. The whole pump is wrapped with waterproof shock‑absorbing PE film, then secured inside reinforced export‑grade plywood case, protecting parts against collision deformation and rust formation during long‑haul ocean transit.
