Product Security

Magnetic drive sealless pumps are the safest and most robust means for liquid transfer. By eliminating the seal, the primary opportunities for leaks associated with traditional sealed pumps are completely removed.


By improving performance and reducing maintenance calls, sealless magnetic drive pumps can dramatically lower downtime and lost production. In sum, this equates to maximized efficiency that can be seen on your bottom line.


Sealless magnetic drive pumps have proven their reliability in even the most severe climate conditions, from the frozen tundra of Siberia to the deserts of the Middle East and the humid climes of Louisianas refineries. In fact, there are Sundyne HMD Kontro pumps that have been in operation for over 30 years and are still running reliably today!


Sundyne HMD Kontro sealless magnetic drive pumps are manufactured to conform to international design and safety standards, including ATEX, ISO, API and ANSI requirements. Plus, with no mechanical seals to leak hazardous chemicals, these pumps offer a clear choice for process industry professionals who regularly deal with volatile or high value materials.


Sealless magnetic drive pumps require less monitoring and maintenance than traditional sealed designed, equating to substantial savings over the life of the pump.



Global service centers keep HMD/Kontro sealless magentic drive pumps operating with peak performance. Standard pumps and parts are available from the factory and in the field.


Key Design Features


Sealless Design

No seals means minimized maintenance requirements, leading to reduced downtime, costs and inefficienacy. Plus, the sealless design allows for total containment, which is essential for handling hazardous, aggressive or valuable product.

Interchangeabile Components

By streamlining the design of our sealless pumps, we have introduced a real level of convenience into the maintenance and upkeep of these pumps. Interchangeable components allow for a reduced parts inventory and can help reduce the amount of time and capital invested in maintenance training.

High Efficiency Wet End

Our sealless pumps deliver maximum flow and head coverage.


High Efficiency Magnetic Couplings

Our coupling designs optimize application to duty conditions.

Wide Choice Of Materials

We offer a wide range of specialized metallurgies in the construction of our sealless magnetic drive pumps to ensure chemical compatibility with your process.


Single Joint Casing & Containment Shell

These features are standard on all of our Sundyne HMD Kontro sealless magnetic drive pumps to reduce and eliminate leaks.

Fully Confined Casing Gasket

By confining the casing gasket, we eliminate the risk of blowout.


Universal Connection Options

We configure all suction and discharge flange connections to meet your exact application requirements.


Modular Rotating Element Cartridge

By building this element out as a modular component, we have enabled our customers to perform efficient replacements and manage their spare parts inventory. Plus, major rotating components can now be removed in a single operation for refurbishment or overhaul.

Robust Magnetic Couplings

Our couplings are designed for full starting conditions and feature protected magnets that are optimized for specific duty parameters.
