Overview

click+drag to rotate

PSU Series pumps are the ideal solution for ultra-high temperature, ultra-high purity recirculation and delivery applications. These PTFE and PFA pumps are completely metal free and operate with a unique shuttle valve that eliminates the need for complicated detents and manual resets. They operate continuously throughout their two-year warranty. They offer air supply pressures up to 7 Bar (100 psi) and operate in thermal cycling applications with fluid temperatures up to 210°C (410°F).

The pumps are available in three models, PSU030, PSU060 and PSU140, which are capable of maximum flow rates of 30, 60 and 140 lpm, respectively.
