PEEK Containment Shell Eliminates Eddy Current Heating and Improves Pump Efficiency
Reduced power consumption and hence energy savings, bringing a lower carbon footprint, is one of the significant reasons why the ZeroLoss containment shell is being specified on more and more HMD Kontro pumps, including the CSA / CSI range for chemical applications. ZeroLoss also brings improved handling of liquefied gases and heat-sensitive liquids.
The PEEK (Poly-Ether-Ether-Ketone) composite containment shell is highly durable, combining low weight with a higher specific strength, which will withstand a pressure of almost 19 bar / 275 psi.
Induction losses, associated with a traditional metallic containment shell, are completely eliminated, so allowing significant energy savings during operation. This can often also contribute to lower capital and installation costs because a smaller motor can be used to drive the pump, so also saving space.
Another benefit of the ZeroLoss containment shell, versus a metallic shell, is that less heat is transferred into the liquid being pumped. The CSA / CSI, when fitted with a ZeroLoss shell, can accommodate temperatures of between -40°C and up to 120°C / -40°F to 248°F.
The ZeroLoss shell is provided with a built-in vortex breaker, within the crown, to eliminate shell erosion. For further information on ZeroLoss, please click here. For further information on the CSA / CSI range of ASME and ISO chemical pumps, please click here.

Composite Containment Shells for Sealless Pumps
Improved efficiency and reduced pump life cycle costs are just two of the benefits of the revolutionary ZeroLoss® containment shell, which is constructed from an engineered composite.
Eddy current heating is a common issue with sealless rotating equipment and the ZeroLoss® shell works to eliminate this in an HMD Kontro magnetic drive pump, providing significant cost savings, increased safety and environmental benefits.
ZeroLoss® Shell Benefits
The ZeroLoss® containment shell is engineered from a proprietary material, which was originally developed for use in the construction of modern, high-tech aircraft. This low mass material blend offers a range of benefits, including:
- Higher efficiency ratings and lower operational costs
- Potential to reduce motor size and space savings
- Improved handling of liquefied gases and heat sensitive liquids
- More robustness in closed discharge conditions
- Greater tolerance of partial dry run conditions
- Resistance to a wide range of chemicals

Essentially, sealless pumps are centrifugal pumps without packed glands or seals. Instead of a seal, there is a static containment shell or shroud, which forms a completely sealed liquid end or pressure boundary.
Prime mover energy is transmitted to the sealed liquid end by a bank of external magnets, which pass force through the containment shell to the inner magnets attached to the impeller shaft, meaning there is no risk of leaks or emissions.
Sealless v Sealed Pumps
It’s necessary to understand what a mechanical seal is to differentiate between the two types of pump. Mechanical seals are designed to maintain their sealing capability by leaking small amounts of fluid in order to keep the seal faces lubricated.
Mechanical seals are widely regarded as the weakest point in any pumping system. In fact, they account for 80% of all pump failures, with the remainder being leakage through static seals such as gaskets or O Rings and bearing failure.
Seals, like bearings, will ultimately wear and, as they wear, the seal faces lose their effectiveness and liquid loss through the seal increases. These fugitive emissions can be costly, resulting in lost time and money, as well as reduced worksite and environmental safety.
WHAT makes a HMD Kontro Sealless Pump different?
