- User-Friendly Vacuum Priming System
The DEFU pump’s self-priming system offers outstanding features such as high air-handling capacity, strong vacuum performance, low operating temperature, and a maintenance-free design. It operates without the need for oil or mechanical seals, ensuring reliable and efficient performance. - P-S-P(Prime-Sleep-Prime) Auto Switch System
The EVP (Electric Vacuum Priming) system automatically enters sleep mode once priming is complete.For general-purpose applications, the EVP system operates for only a few seconds during the priming process. This minimal usage significantly reduces the need for daily maintenance and makes spare part replacement virtually unnecessary throughout its service life. - Dry Running Protection System
Available configurations include an oil reservoir–lubricated mechanical seal, an air cushion–protected mechanical seal, and grease-lubricated lip seals. Each of these options is designed to ensure reliable dry running performance over extended periods. - Easy Maintenance Structure
The vacuum pump cover can be conveniently removed from the non-drive end, allowing the slides to be easily pulled out for inspection or replacement. Maintenance of the centrifugal pump is also simplified — the impeller, wear ring, and mechanical seal are easily accessible without the need to remove the diesel engine or pump frame, thanks to the fully openable suction cover design. - Mechanical Seal System
The DEFU mechanical seal system utilizes Type I and Type II mechanical seals, eliminating the need for flush water or packing. This not only reduces operating costs and service time but also avoids messy leaks. The result is a longer-lasting seal, minimizing downtime and lowering maintenance costs throughout the pump’s service life.
