SH200A3 Hydraulic Main Pump | K3V112DTP‑9N24 Axial Piston Pump | Sumitomo Excavator Aftermarket Replacement Parts

Product Brief

This K3V112DTP‑9N24 electronically controlled dual‑displacement axial piston pump serves as the core hydraulic power source for Sumitomo SH200A3 medium excavator. Suited for urban foundation excavation, stockpile handling, road reconstruction and site backfill assignments, this pump converts engine mechanical power into adjustable high‑pressure hydraulic flow to realize bucket digging, boom lifting, swing rotation and compound combined movements. This aftermarket replacement assembly is widely procured by field repair workshops, equipment rental businesses and cross‑border spare‑part distributors across Africa, Southeast Asia and Middle East for full hydraulic system overhaul and direct pump replacement.

Under long‑duration cyclic variable‑load operation, the main pump is prone to cylinder block galling, piston shoe scuffing, valve plate scratching and progressive internal leakage. Typical failure manifestations include weakened digging thrust, slow multi‑action response, reduced working efficiency, continuous hydraulic oil overheating, obvious vibrating knocking noise from pump housing and power drop after machine reaches operating temperature. Sudden pump failure will halt construction progress and generate extra emergency repair expenditure for project operators.

Our aftermarket hydraulic pump strictly complies with OEM drawing standards for mounting flange dimension, spline tooth profile, solenoid mounting position and system pressure setting. No secondary cutting, drilling or adapter modification is needed for on‑site swap, direct drop‑in installation effectively shortens equipment downtime. As a practical cost‑saving alternative to high‑priced genuine pump assemblies with long lead‑time, this unit delivers stable hydraulic output performance and meets bulk‑volume purchasing demands for medium‑size excavator spare‑part merchants.

Unique Product Competitive Advantages

1. Full‑spec compatibility for Sumitomo SH200A3 hydraulic control system, not universal for other excavator series
Manufactured according to original technical specifications, this main pump keeps consistent oil port layout, solenoid installation position and pressure calibration parameters. Precisely lapped friction pairs effectively suppress internal leakage after assembly. No extra machining work is required for field installation.
2. Upgraded friction‑pair craftsmanship for prolonged service life under cyclic construction loads
Many low‑cost substitute pumps suffer obvious pressure decay after limited working hours because of inferior internal friction‑pair raw materials. Our core functional components adopt standardized quenching and fine‑grinding process, improving wear‑resistant capacity under frequent load fluctuation. It helps fleet operators reduce pump replacement frequency for heavily‑utilized SH200A3 machines.
3. Multi‑dimensional bench inspection before shipment to eliminate hidden field failure risks
Each finished hydraulic pump undergoes pressure endurance test, flow calibration and tightness leakage test on professional hydraulic test bench before packing. Defective units are filtered out in factory, avoiding maintenance re‑work burden and unexpected jobsite shutdown losses for end‑users.
4. Cost‑effective aftermarket solution to control medium‑tonnage excavator maintenance budget
Genuine OEM main pumps for Sumitomo SH200A3 carry high procurement cost and lengthy delivery cycle. Our factory‑direct aftermarket pump achieves comparable working stability and system matching performance, cutting annual overhaul expense for enterprises operating multiple medium excavator fleets.
5. Flexible global logistics arrangement for wholesale buyers
In‑stock goods can be dispatched quickly upon payment confirmation. Air freight supports urgent breakdown repair orders; consolidated sea freight and full‑container service offer cost‑saving options for long‑term bulk importers.

Factory Production Strength

Our manufacturing facility focuses on R&D and mass production of aftermarket hydraulic main pumps, travel motors and swing motors covering mainstream excavator brands. We own complete production workflows: alloy steel forging, precision grinding, professional heat‑treatment and finished‑product hydraulic bench testing. Dedicated simulation equipment reproduces real‑world construction variable‑load operating status to continuously optimize component wear resistance and pressure stability. Our hydraulic assemblies are exported to multiple overseas markets and maintain long‑term stable cooperative relationships with global construction machinery spare‑part wholesalers.

Frequently Asked Customer Questions

Q1: Can this K3V112DTP‑9N24 main pump fit other Sumitomo excavator models besides SH200A3?
A1: Cross‑model installation is not supported. Different excavator main pumps differ in flange dimension, solenoid parameters and pressure setting values. Please double‑check machine model and OEM part number before placing orders.

Q2: What hydraulic malfunctions can this main pump resolve?
A2: It solves faults caused by worn pistons, scratched valve plate and damaged internal components: weak digging power, sluggish compound movements, high hydraulic oil temperature, internal leakage and abnormal knocking noise of main pump.

Q3: Are tier‑based preferential prices available for large‑volume bulk orders?
A3: Yes, volume‑based discount policy applies according to purchase quantity. We can arrange full‑container sea shipment to reduce comprehensive logistics costs.

Q4: What packaging measure is adopted for long‑distance ocean‑going transportation?
A4: Anti‑rust oil is evenly coated on all metal surfaces. The whole pump is wrapped by waterproof shock‑resistant PE film, then secured inside reinforced export‑grade plywood case, preventing collision deformation and moisture corrosion during long overseas transit.
