Overview

click+drag to rotate

PSH Series pumps are the ideal solution for high temperature, ultra-pure recirculation and delivery applications. These Teflon® 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 perform safely and reliably running continuously throughout their two-year warranty. They offer air supply pressures up to 5.5 Bar (80 psi) and operate in thermal cycling applications with fluid temperatures up to 145°C (293°F). The pumps are available in three models, PSH015, PSH030, PSH060 and PSH140, which are capable of maximum flow rates of 15, 30, 60 and 140 lpm, respectively.
