The DP pump is a vacuum generating device. It relies on two high-precision screw rotors rotating synchronously and reversibly without contact inside the pump chamber to complete air suction, compression and exhaust. Its core advantage is that no working fluid is required for sealing during operation, which ensures the cleanliness of the vacuum chamber.

Dry screw vacuum pump is a vacuum generating device that produces suction, compression and exhaust by means of two high-precision screw rotors rotating synchronously in opposite directions without contact in the pump chamber. Its core feature is that no working liquid is required for sealing during the entire operation, thus ensuring a clean vacuum chamber.

The core components of the DP vacuum unit are the screw pump and the roots pump, representing a highly efficient integration model of modern industrial vacuum technology. By intelligently combining a dry screw vacuum pump as the backing pump with a roots vacuum pump, it fully leverages the advantages of both, delivering high pumping speed, high energy efficiency and clean vacuum performance over a wider pressure range.
The complete unit features core advantages including oil-free cleanliness, low noise, energy saving, stability and durability. It is widely used in high-end manufacturing fields such as lithium battery new energy, semiconductor manufacturing, photovoltaic industry and precision processing, providing a one-stop, efficient and reliable vacuum solution for large-capacity and high-precision vacuum processes.
