Used PFEIFFER A1803H #9102025 for sale

PFEIFFER A1803H is a high performance multi-stage, medium sized Roots-type pump that is optimized to operate in high-vacuum and low flow applications. The pump has a maximum pumping speed of 830 cubic meters per hour (m3/h) with an ultimate pressure of 5 mbar. A1803H is particularly well suited for operation with corrosive or hygroscopic materials, because its rotor is corrosion resistant and highly efficient. The pump operates using a two-stage rotary displacement process. In the first stage, a pair of mechanically linked lobes rotate within the housing to create a vacuum. The motors used to run the pump can run at speeds of up to 1800 rpm. During the second stage, rotors with offset lobes create compression which increases the pressure of the gas or vapor being absorbed by the pump. These two stages work in tandem, creating a vacuum, compressing the gas, then drawing it into the pump. PFEIFFER A1803H is designed to run with an optional control unit, which uses the pressure and temperature readings to regulate the pump's performance. This robust control system allows users to set the operating parameters of the pump safely and accurately. Additionally, the control unit puts the pump into a standby mode once the desired vacuum has been reached, thus saving energy. In addition to the mechanical components, A1803H also features a highly efficient, oil-sealed sealing system and a PFEIFFER-designed cooling system. These features ensure a safe and stable operation with minimal operating noise and longer pump life. PFEIFFER A1803H is also easy to maintain and repair. It comes with a loose set of tools, enabling owners to quickly take apart the pump and diagnose potential issues. The components of A1803H are also user-serviceable, allowing for maintenance and replacement processes to be completed rapidly. Given its versatility, durability, and user-friendly operation, PFEIFFER A1803H pump is an excellent choice for a wide range of industrial and research applications. It is well-suited for operating in low and medium-vacuum environments as well as for handling corrosive or hygroscopic materials. The performance, reliability, and energy saving features of this pump ensure that it will provide superior performance in any application.
