Introduction Core Components Product Features Parameters & Pumping Speed Curve Diagram Product Structure Diagram

Introduction

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.

Product Features

Wide pumping speed range

The pumping speed ranges from 1000 m³/h to 7000 m³/h. The Roots pump and screw pump operate in a scientifically coordinated manner: the screw pump quickly completes rough pumping and pressure establishment, while the Roots pump precisely boosts pressure and improves efficiency, achieving dual breakthroughs in pumping speed and vacuum level.
The ultimate vacuum can reach below 0.1 Pa, easily adapting to the vacuum requirements of different chambers and production lines with varying capacities, and significantly shortening the process cycle.

Intelligent interaction hub, control at your fingertips

Equipped with a high-resolution touch screen, it creates an intuitive graphical human-machine interface. The operation logic is clear and concise, with key operating parameters visible at a glance. The system supports real-time panoramic monitoring of the vacuum unit status, and immediately triggers multi-stage sound and light alarms with accurate positioning in case of abnormalities, realizing the whole-process intelligent management from interaction to operation and maintenance.

Multi-mode intelligence, balanced efficiency and performance

One system, multiple performances. Intelligent operation schemes are tailored for various scenarios including efficient production, green energy conservation, and stable heavy-duty operations. With simple selection, an optimal balance can be achieved among extreme efficiency, economic cost, and exceptional reliability, empowering flexible and diverse production strategies.

Simplify complexity for easy maintenance

Simplified design of water cooling channels and water cooling control; the quick-connect cooling system and fully standardized interface design enable rapid disassembly, assembly and replacement of the cooling water circuits.

Standardized interface

Multi-protocol compatible expansion for easy communication and control with external equipment. Optional: RS232/485, Profibus, EtherCAT, and Ethernet.
