NIKKISO Canned Motor Pumps are seal-less, leak-free pumps designed for liquid transfer applications involving high-temperature, hazardous, corrosive, or difficult-to-handle fluids.
The pump and motor are integrated into a sealed construction, helping prevent leakage while supporting reliable operation in demanding industrial process environments.
These non-seal pumps are designed to handle a wide range of pressures, temperatures, viscosities, and liquid conditions.

With compact construction, low vibration and noise, and options for specialized applications such as high-viscosity fluids, slurry handling, liquefied gases, high-melting-point liquids, and high-head service.
NIKKISO Canned Motor Pumps provide flexible pumping solutions for critical process systems. The product line includes multiple configurations to support application-specific requirements, including standard, high-temperature, reverse circulation, self-priming, multistage, and API685-compliant designs.
