HMD Kontro sealless magnetic pumps are designed for reliable and safe operation in chemical processing and downstream refining applications.
HMD Pumps pioneered the sealless magnetic drive pump over seventy years ago, breaking new territory in fluid handling technology. Sundyne combined HMD with the American company Kontro to create HMD Kontro, which stands as the most safe and reliable Sealless magnetic drive pump manufacturer operating today.
As a proven alternative to traditional sealed pumps, HMD Kontro sealless magnetic drive designs present absolutely no risk of emissions or leaks, which can harm productivity, personnel and the environment. With no seals to replace your spare parts inventory can be kept at a minimum, reducing your operating budget.
HMD Kontro sealless magnetic drive pumps are extremely safe for process engineers who must handle high temperature, toxic, lethal, carcinogenic, flammable, expensive, caustic, heat transfer, corrosive, aggressive, high viscosity, high vapor pressure and volatile process fluids.
Sundyne engineers worked to define and establish the API 685 standards and HMD Kontro sealless magnetic drive pumps are widely utilized for processing light hydrocarbons in refining, petrochemical production, midstream natural gas plants, pharmaceutical manufacturing and general industry. Several HMD Kontro models meet that standard and are available for numerous API applications.
Standard chemical sealless magnetic drive by HMD Kontro pumps meet rigorous ASME/ANSI B73,3 and ISO 2858 standards.
