DRP hydraulic coupling Roots pump
Company Name :
Shanghai Aifa Technology Co., Ltd.Brand :
AIFAThe DRP series hydraulic couplings for Roots pumps are based on the traditional Roots principle. The mechanical booster pump is a widely popular type suitable for applications requiring a high pumping speed within a pressure range of 1 Pa to 1000 Pa. It typically requires a main pump to operate, with the Roots pump used to enhance the system's pumping speed and vacuum level, while avoiding exposure to corrosive process media at the same concentration as the main pump, thereby ensuring high reliability.
When the DRP Roots pump is used in conjunction with a primary oil-free dry pump, it can form an oil-free vacuum system. The role of the Roots pump is to increase the system's pumping speed and improve the vacuum level. The Aifa Roots pump employs advanced hydraulic drive technology, allowing for automatic speed adjustment, enabling it to start under atmospheric pressure or simultaneously with the main pump, significantly simplifying system configuration and operation while greatly enhancing system reliability.
The hydraulic drive structure allows the Aifa Roots pump to start directly under atmospheric pressure or high differential pressure.
The Roots pump can be started and stopped simultaneously with the main pump.
The Roots pump can automatically adjust its speed to prevent overload or overheating. The Roots pump can start in advance under high differential pressure, thereby reducing pumping time and improving system pumping efficiency.
When foreign objects enter the pump chamber or when pressure changes suddenly, automatic deceleration protection is activated, resulting in an extremely low failure rate.
The configuration is simple, requiring no bypass piping, valves, or frequency converters, thus saving costs and facilitating operation.
It operates smoothly and quietly, with minimal vibration, and the maintenance of the pump is very straightforward.
Application fields include pharmaceuticals, chemical engineering, electronics and photovoltaics, metallurgy, aerospace, and nuclear industry.
