Pulsafeeder’s Isochem pumps safely handle hazardous, highly corrosive, explosive or toxic chemicals. They provide safe, leak-free service because the magnetic coupling eliminates the need for traditional sealing methods, such as mechanical seals or packing, the main source of leakage problems on pumps. As a result, downtime and maintenance costs are greatly reduced. And there are no worn seals to replace.
Isochem pumps are offered in two different designs, centrifugal and positive displacement gear type, providing extensive capabilities. The CM Series of centrifugal pumps is available as single or multi-stage units (up to five stages). Our GM Series gear pumps are ideal for use when you encounter viscosity or suction lift requirements. The are available in 316 stainless steel, Alloy 20 and Alloy C construction for maximum chemical resistance.

State-of-the-art magnetic technology provides a safe and reliable pump for difficult applications. The drive magnet assembly is fixed to the motor shaft. The driven magnet assembly is attached to the pump shaft and rotates as the drive magnet rotates as a result of magnetic force. The high torque capability of the rare earth samarium cobalt permanent magnets alleviates the possibility of coupling slippage. The Alloy C Can separates the magnetic assemblies and contains the liquid.

Isochem series pumps offer two principal designs to handle a broad range of applications over wide temperature, viscosity and pressure variations. The are ideal for vacuum service and transfer of expensive, hazardous and/or corrosive chemicals over the entire pH range. Seal-less features make them perfect for environments subject to federal regulations.
