Syngenta Spain had elected to source magnetic drive sealless pump solutions that can handle high temperatures and volatile substances associated with chemical pump applications.
HMD Kontro supplied chemical service 50 Hz CSI magnetic drive pumps, specifically CSI 65-40-200 H DB6 and CSI 80-50-200 DB6, in 316 stainless steel material, with a close coupled configuration, and each one mounted on its own baseplate.
Designed to handle Tefluthrin, a hazardous substance and active ingredient, the CSI sealless pump range can safely transfer liquids from the reactor to the storage tank, together with a constant recirculation of the chemical within the storage tank.
Syngenta also chose the optional feature of a secondary control system and a leakage sensor.
The secondary control system comprises a leakage restriction device located between the rotating shaft and the static coupling housing to form a secondary pressure boundary.
This design provides additional safety and control beyond the primary pressure boundary of the pump. In the unlikely event of a breach of the containment shell, leakage of the process liquid to atmosphere is restricted by the secondary control seal.
The leakage sensor installed within the secondary pressure area then immediately halts the pump to enable the primary pressure boundary failure to be detected and addressed, providing greater safety for operators and the environment.
Notable features and benefits of the CSI range include the use of the ZeroLoss containment shell for improved efficiency and tolerance to system upsets.
The highly efficient hydraulics allow maximum flow and head coverage and in addition, the components are highly modular and interchangeable. With improved pump performance and reduced maintenance, the CSI delivers maximum uptime and minimum downtime, together with the ensuing cost savings.
