Magnetic Drive Pumps

A reliable and proven sealless solution.

Magnetic Drive pumps transmit drive through the use of permanent magnets with a containment shell (typically made of Hastelloy) providing leak free operation.

Pump internals are supported by Silicon Carbide (SiC) product lubricated slide bearings. With all designs being self-venting as per API685, pumps are a safe reliable solution for transferring media. Pumps can be supplied in single and multistage built in accordance to, or the intent of API685 (the scope of API685 only covers single stage OH2 style units). With our partners we are able to provide pumps with couplings capable of transmitting torques up to 500Nm. Units are also able to work with NPSHR’s as low as 0.5m. Designs up to 450°C can be supplied and no designs require cooling water.

Renroc has designs in compliance with API685 as well as designs to ISO, ANSI and manufacturer standards.

A superior option to mechanical seals particularly dual seal arrangements.
