Core Technologies
ECO-Friendly Vacuum Priming Innovation
The EVP system features a state-of-the-art 3rd generation vacuum pump technology, enabling any centrifugal pump to complete priming within seconds. It boasts remarkable capabilities such as high air processing capacity, strong vacuum, low operating temperature, and maintenance-free operation without the need for oil or mechanical seals. This sets a new standard in the self-priming pump market.
Prime-Sleep-Prime (P-S-P) Auto Switch System
The EVP system transitions to a sleep mode automatically once priming is complete. For general applications, the EVP system only operates for a short duration, making daily maintenance or part replacement almost unnecessary throughout its lifecycle.
Dry Running Protection System
Pumps can operate dry for extended periods without damaging their mechanical seals. This is due to a protection system comprising a standard mechanical seal, oil chamber, and oil reservoir connected by hoses to form an oil circulation loop. An optional air-cushion design on the mechanical seal’s stationary seat eliminates the need for oil lubrication during prolonged dry running. Alternatively, a set of lip seals can replace the mechanical seal, enhancing sealing effectiveness and simplifying maintenance.

Advanced Cooling System
A pressurized cooling flush water is introduced from the centrifugal pump’s water passage into the vacuum pump’s water jacket, cooling the entire vacuum pump quickly and effectively. This pressurized water flow helps maintain a low operating temperature, significantly extending the EVP system’s lifespan.
User-Friendly Dissasembly Design
The vacuum pump’s cover can be easily removed from the non-drive end for inspection or replacement. The centrifugal pump’s impeller, wear ring, and mechanical seal are also accessible without removing the diesel engine or pump frame, facilitating straightforward maintenance.
Innovative
Non-Clogging Impeller
Equipped with wide water passage impellers that can handle solids with a diameter of 3” or larger. These pumps are ideal for critical applications like sewage, sludge, and fluids containing large stones.

Self-Cleaning
Mechanism
The stuffing box features a unique structure that mixes and discharges solids. Small solids or sand entering the stuffing box are mixed by built-in mixers and expelled using the centrifugal force of the impeller back vanes, preventing clogging of the mechanical seal spring and avoiding seal failures.
Versatile Technology
The powerful EVP Priming System is versatile and suitable for various fluid industry applications, including dewatering, bypass, firefighting, lift station backup, mining, irrigation, water transfer, and well point systems.
