K3v140dt hydraulic pump

The K3V140DT is a high-pressure swash plate type axial piston pump commonly used in heavy excavators (30-ton class). You must verify the rated pressure (34.3 MPa) and maximum pressure (39.2 MPa). Ensure the displacement is exactly 140cm³ x 2 and check the gear ratio and spline count on the input shaft to ensure perfect matching with the engine flywheel. For B2B buyers, it is critical to confirm if the pump includes the PTO (Power Take-Off) for auxiliary functions.

Genuine parts carry the original brand logo (e.g., Kawasaki) and offer the highest reliability but at a premium price. OEM (Original Equipment Manufacturer) pumps are produced by the same factories but sold under a different brand, offering 99% identical performance at a 20-30% lower cost. Aftermarket pumps are budget-friendly; however, you must ensure the manufacturer uses high-strength copper alloy for the cylinder block and hardened steel for the pistons to prevent premature wear.

Suppliers should ideally hold ISO 9001:2015 certification for quality management. Specifically for hydraulic components, ask for factory pressure test reports and noise level certifications. A reputable supplier on Made-in-China.com should provide a 12-month warranty and a video of the bench test showing the pump reaching its rated flow and pressure without leakage before shipment.

This pump is primarily used in construction machinery (excavators like Volvo, Doosan, Hyundai) and industrial hydraulic systems. To ensure longevity, the hydraulic oil must be filtered to NAS Grade 9 or better. Advise your end-users to replace the pilot filter and main return filter whenever a new pump is installed to prevent residual metal shavings from the old pump from damaging the new unit.

Always request a detailed nameplate photo and a technical drawing of the mounting flange and shaft. Use Third-Party Inspection services (like SGS or Intertek) available through Made-in-China.com to verify the internal components' material quality. Ensure the contract specifies that the serial number on the test report must match the physical pump delivered.

Since the K3V140DT is heavy (approx. 250kg - 300kg), shipping costs significantly impact the total cost. Negotiate FOB (Free On Board) terms if you have a reliable forwarder, or CIF (Cost, Insurance, and Freight) to simplify the process. For bulk orders of 5+ units, aim for a 10-15% volume discount. Request customized wooden crate packaging with shock-absorbing foam to prevent shaft damage during maritime transit.

Utilize Secured Payment services on Made-in-China.com to ensure funds are only released after proof of shipment. Check the HS Code (typically 8413.50) to calculate accurate import duties in your country. Be aware of anti-dumping duties or specific trade sanctions that might apply to heavy machinery components in your region to avoid unexpected customs seizures.
