HMD Kontro – The Sundyne Sealless / magnetic drive Family

Prior to joining the Sundyne portfolio, HMD Pumps pioneered the sealless magnetic drive pump over sixty years ago, breaking new territory in fluid handling technology. The HMD sealless magnetic drive design affords a wide range of operational benefits, making them a worthwhile alternative to traditional sealed pumps.

These Sundyne sealless magnetic drive pumps afford the user no risk of emissions or leaks, which can harm productivity, employees and the environment. With no seals to replace and streamlined components that are used across the entire Sundyne sealless pump product line, spare parts inventory can be kept at a minimum, helping to reduce your operating budget.

HMD Kontro pumps are used in a wide range of applications and industries and are vital in petroleum, chemical, gas production, pharmaceutical and general process industries that involve toxic, fine, corrosive and aggressive liquids that must be handled.

AFH are exclusive providers and authorised service partners for Sundyne and HMD Kontro.
