Engineered For Environmental Safety.

Pulsafeeder’s lsochem 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.

lsochem 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 GMC Series gear pumps are ideal for use when you encounter viscosity or suction lift applications. They are available in 316 stainless steel Alloy 20 and Alloy C construction for maximum chemical resistance.

Advanced Magnetic Technology.

State-of-the-art magnetic technology provides a safe and reliable pump for difficult applications. The drive magnel assembly is fixed to the motor shaft. The driven magnet assembly is attached to the pump shaft and rotates when the drive magnet rotates as a result of magnetic force. The high torque capability of the neodymium iron and rare earth samarium cobalt permanent magnets alleviates the possibility of coupling slippage. The 316 SS and Alloy C Can separates the magnetic assemblies and contains the liquid.

lsochem Offers Many Benefits.
  • Minimizes exposure of your personnel to hazardous chemicals.
  • Eliminates contacting seal faces which are prone to wear and leakage.
  • Provides superior corrosion resistance and minimizes heating (due to eddy-current effect) by utilizing an Alloy C Containment Can
  • Eliminates costly seal flush systems required on all pumps with double mechanical seals
  • Reduces downtime and maintenance costs through extended service intervals.
  • Eliminates alignment problems inherent in direct-coupled units.

lsochem Series pumps offer two principal designs to handle a broad range of applications over wide temperature, viscosity and pressure variations. They 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

Isochem Magnetic ImageIsochem® GMC1

Magentically Driven Sealless Gear Pump

Pulsafeeder’s Isochem® GMC1 Series is a compact magnetically driven sealless gear pump designed for safely handling highly corrosive, hazardous, explosive, or toxic chemicals and industrial applications. The GMC1 provides safe leak free service since the magnetic coupling eliminates the need for traditional shaft sealing methods such as mechanical seals and shaft packing which are the primary source of leakage in rotating shaft pumps. Furthermore, expensive seal flushing or lubrication systems are eliminated. Consequently, mean time between failures is maximized while maintenance and operation costs are minimized!

Operating Benefits

Flows to 0.8 gpm (2.8 lpm) • Pressures up to 300 psi (20.7 bar) • Laminar, non-pulsating flow • Compact, close-coupled foot print eliminates issues related to alignment between pump and motor • Leak free service minimizes exposure of your personnel to hazardous chemicals • Ideal for viscosities from less than 1 to 1000 cPs • Suitable for vacuum service • Can be used for metering or transfer of expensive, hazardous and corrosive chemicals over the entire pH range
