BALZERS RKP 630 is a dry running rotary vane pump for handling moderate amounts of gases, vapors, and liquids. It is designed to supply pressure up to 0.2bar gauge. It features a polymethylpentene body with a reinforced core and optional gas-tight or carton-filled connections. The polymethylpentene construction makes the pump resistant to corrosion and chemical attack, and its reinforced core provides high vibration resistance. RKP 630 has a vacuum/pressure and non-absorbing/gas-tight connection with an internal and external flange, ideal for use in systems with corrosive or aggressive liquids and gases. Inside, the pump is equipped with robust, pressure-balanced, self-compensating rotary vanes that ensure the highest levels of efficiency and reliability. The vanes are designed to prevent any contact between them and the body, and thus ensure that lubrication is always maintained. BALZERS RKP 630 has a maximum speed of up to 9500 rpm and a maximum lift of 9 mm. It is also equipped with a thermally protected motor with permanent lubrication, allowing it to handle continuous operation even in hot conditions. The motor features a two-step drive system, allowing it to achieve maximum efficiency and low noise levels. The pump is also easy to install and includes a modular design so it can be used in a variety of applications. With its rugged construction and reliable performance, RKP 630 is the perfect choice for applications requiring a robust, reliable, and efficient pump. It is designed to handle light-weight to heavy-duty applications, including industrial, commercial and residential uses. The pump also offers superior levels of safety and performance and can easily integrate into any existing pipeline.
