HMD Pumps pioneered the sealless magnetic drive pump over sixty years ago, breaking new territory in fluid handling technology. Sundyne standard sealless pumps keep your personnel, facilities and the environment safe. Some of the HMD pumps can built to meet exacting American Petroleum Institute API 685 standards for sealless magnetic drive pumps, and they are purpose-built for use in refinery applications and environments.

The HMD sealless magnetic drive design affords a wide range of operational benefits, making them a worthwhile alternative to traditional sealed pumps. These sealless pumps present absolutely 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 HMD product line, spare parts inventory can be kept at a minimum, helping to reduce operating budget. Using Sundyne HMD Kontrol pumps in your workflow equates to maximized reliability and uptime.
