Where fluids handling applications involve hazardous, hard-to-handle chemicals, magnetically drive (mag-drive) pumps are designed to provide reliable, leak-free operation, with no environmental emissions, no double mechanical seal costs and no need for seal-support systems.
Available from Michael Smith Engineers, the new models from Finish Thompson UC are the UC1518L, a low flow version of the standard UC1518 for applications requiring higher heads (up to 69 metres) at lower flows (1.13 to 8.6 m³/h), the UC2110, which is a 4-pole configuration, with a 2-pole version also under development, and the UC6410 anpowerful option designed forflows up to 329 m3/hr.
The pumps combine a tough ductile iron casing with a Tefzel (ETFE) lining to ensure a high level of corrosion resistance and feature powerful neodymium magnets which drive the impeller through a carbon-filled PTFE lined barrier for dependable, leak-free operation.
In addition, a Dri-Coat silicon carbide bearing/shaft option prevents catastrophic failure in the event of short-term dry-running, while a two-piece dynamically balanced outer drive magnet with multiple pole options matches drive to motor power for greater efficiency.
This outer drive magnet incorporates Finish Thompson’s “Easy-set” mounting system so that the drive magnet can be fitted to the motor shaft without having to measure the magnet set-height, ensuring a perfectly set magnet thereby removing a potential cause of misalignment.
