Used EDWARDS QDP40 #9291862 for sale

EDWARDS QDP40 is a fixed displacement, positive displacement regenerative turbine pump, designed for general purpose applications where a pressure range of up to 40 Bar is required. The high output pressure of the pump makes it suitable for both high pressure and higher flow applications. The pump consists of a small low-speed turbine stator which drives an impeller, enclosed in a heavy duty fabricated housing. All components are designed and manufactured to ensure long life and reliable operation in harsh industrial environments. The main advantage of a regenerative pump is the ability to produce volumetrically consistent discharges over a wide range of operating conditions. This is especially beneficial when delivering additives, such as dyes, that need to be applied with precision and uniformity. EDWARDS QDP 40's advanced impeller design gives improved efficiency and volumetric consistency, making it the ideal choice for large-scale additive delivery applications. In operation, QDP40's impeller turns at a slow speed, typically between 600 and 800 RPM, creating a low-pressure differential between its inlet and outlet ports. This low pressure differential significantly reduces the noise generated by the pump, while simultaneously providing greater efficiency with less stress on internal components. It also reduces the need for specialised motors or added ancillary components such as soundproofing. QDP 40 is designed for quiet and reliable operation in noisy environments, including locations such as chemicals plants, breweries and power stations. The robust housing is made from cast iron, providing excellent protection from corrosion, wear and tear. It also features integrated vibration dampening elements that significantly reduce noise levels without sacrificing performance. EDWARDS QDP40 features a number of unique, user-friendly attributes, including an integrated differential pressure control valve that automatically adjusts pump speed as pressure fluctuates. Additionally, it includes a spark-free bypass valve which can be used to provide a faster response time during sudden load and unload cycles. Furthermore, motor protection features such as an erosive-resistant shaft seal and anti-suck back valve protect the pump during abnormal operational conditions. In conclusion, EDWARDS QDP 40 is a robust and reliable regenerative pump suitable for both high and low pressure applications. It provides volumetrically consistent, low-noise operations and a user-friendly feature set that includes pressure control, spark-free bypass valves and motor protection components. Its durable housing ensures long life and reliable performance in the toughest of industrial environments.
