Used EDWARDS STP-451 #293658951 for sale

EDWARDS STP-451 is an electron-beam-welded dry scroll vacuum pump. It is a highly efficient and rugged rotary vane pump that has been designed to deliver both high vacuum and low pumping speeds in an affordable price point. STP-451 has been designed to provide up to a 25 mbar vacuum as well as a rotational speed of 1450 RPM. This pump is largely used within laboratory settings for applications such as degassing, desublimation, backing pumps for freeze drying, freeze-drying pumps, and for vacuum evaporation. The main feature of EDWARDS STP-451 is its dry scroll design. This design ensures no bypassed gas output and the efficient operation of the pump is ensured by having no seals or lubricated parts. This ensures minimal maintenance needs. Additionally, STP-451 has a low noise, low vibration output which further enhances its user-friendly appeal. When it comes to connecting, EDWARDS STP-451 has a built-in KF-25 pump flange connection on its exhaust port. This design allows for a quick and easy connection to additional vacuum components. Performance-wise, STP-451 operates at a very low power consumption. The power is transformed into rotational movement to move a rotor which, in turn, creates a lower pressure inside the vacuum chamber. This is achieved by having a set of three scroll vanes that interact with the body of the pump to increase the overall efficiency of the vacuum. When it comes to safety, EDWARDS STP-451 is designed to meet any safety regulations that need to be in place. Its built-in thermal protection system uses temperature sensors to ensure that the pump is not working at too high a temperature as this could cause it to overheat. Finally, STP-451 is an ideal choice for a variety of industrial and lab applications. Its affordable price point makes it a highly desirable option for many looking to create high-quality vacuum systems with affordable components. Its quick and easy setup, durable construction, and reliable performance make it a great choice for vacuum needs both large and small.
