Used EDWARDS STP-451 #293595558 for sale

EDWARDS STP-451 pump is a positive displacement dry scroll Mechanical Vacuum Pump that offers tight seal technology and reliable performance for a range of applications. It features an oil-free design, making it non-contaminating and ideal for the pumping of corrosive or highly reactive gases. This model can be configured with up to four stages of compression, which helps to provide the user with higher levels of flowrates and potential performance advantages. STP-451 also operates at higher inlet pressures than comparable pumps, making it ideal for high vacuum processes or applications involving the transfer of multiple gases. The pump is also well suited to extreme environments, with its dependable performance in temperatures ranging from -40°C to +60°C. The innovative technology contained within EDWARDS STP-451 includes ScrollPlus™ lubricated face technology that offers a dynamic seal between the compression stage pairings to ensure effective performance. This improved leakage control also provides higher inlet compression pressures, decreased power consumption and guaranteed performance over an extended lifespan of the pump. The scroll technology further improves efficiency with its lack of contact points and improved lubrication, reducing chances of corrosion or contamination due to friction. In addition, the no-contact design ensures longer service life with minimal maintenance requirements. It works by trapping the local running media to avoid contamination of the process media, leading to greater accuracy and enhanced performance. The pump itself is constructed of robust materials that provide durability and extend its lifespan. The motor drive is equipped with a built-in vane-type air motor, with its housing made from stainless steel for added protection. Further features include a built-in fluid recirculation system, built-in pressure and temperature sensors, and an adjustable gas ballast valve to help minimize the amount of entrained gas. In terms of operation, STP-451 is easy to install and requires zero routine maintenance, making it a highly cost effective and reliable choice for many industrial applications. The design of the pump also ensures low vibration, noise and operating temperature, making it suitable for applications in sensitive environments. Furthermore, its powerful and efficient design the pump is designed to be energy-saving and environmentally friendly.
