A high-pressure high-temperature magnetic circulating pump is described. The design is based on the concept of contactless bidirectional pumping action. This pump can deliver a continuous flow at temperatures up to 175°C and pressures up to 2000bars. Wetted parts are fabricated from stainless steels, there are no elastomeric seals or lubricants required, and the pump can be physically mobile during operation. Tests with toluene at ambient temperature and pressure showed that volumetric flow rates of up to 320cm3min−1 and pressure heads of up to 2.2bars could be achieved.
