The KTN/KN series diffusion vacuum pump is an internally heated system designed to achieve high vacuum conditions between 10^-4 Pa and 10^-5 Pa, with pumping capacities ranging from 3100 L/s to 110000 L/s. It features integrated observation windows, dedicated oil inlet and outlet ports, overheat protection for pump oil, and cooling water temperature alarms. The heating rods are arranged in parallel and can be replaced without shutting down the unit, reducing thermal cycling and improving operational uptime.
This pump uses a stretched metal construction to minimize weld cracks and out-gassing, enhancing structural integrity and vacuum purity. When operated with standard pump oil, the back-streaming rate is 1×10^-3 mg/cm²·min; with 275 silicon oil, it drops to 1×10^-4 mg/cm²·min. The ultimate vacuum performance is below 10^-6 Pa, making it suitable for applications requiring low contamination levels. The design eliminates the need for external water-cooled baffles, simplifying system integration.
These pumps are commonly used in vacuum coating, electron beam welding, aerospace testing chambers, and high-temperature vacuum furnaces. Buyers include manufacturers of optical coatings, semiconductor equipment, and research labs in aerospace and materials science. Trade terms typically follow FOB or CIF from Shanghai or Ningbo ports. Packaging includes wooden crates with internal foam padding, and the unit requires pre-installation alignment checks due to its sensitivity to tilt and vibration.

Before placing an order, verify the pump’s exact model variant (KTN or KN), the type of heating rods installed, and the oil type used in testing. Request a factory test report showing the ultimate vacuum achieved and oil back-streaming measurement under load. Confirm that the unit has been pressure-tested and that all electrical components are rated for your local voltage and frequency. Do not rely on generic product images alone.
Lead time for this pump is typically 4 to 6 weeks after order confirmation, but this is not guaranteed without written agreement. Incoterms are usually FOB Shanghai or Ningbo, and payment is commonly via T/T 30% deposit and 70% before shipment. Buyers must confirm the container type (dry or open-top), crating method, and whether lifting eyes are included. Export documentation should include a packing list, commercial invoice, and certificate of origin.
On arrival, inspect the pump for shipping damage, especially to the flange and oil ports. Verify the oil level and check for signs of leakage or contamination. Perform a dry vacuum test using a calibrated gauge before connecting to your system. Request a user manual in English and confirm that the alarm sensors (oil and water temperature) are functional. Retain the original packaging for potential returns or warranty claims.
