ZeroLoss Containment Shells For Magnetic Drive Pumps Expanded

HMD Kontro has expanded the ranges for its ZeroLoss™ containment shells to Frame l, ll and lll versions of its most popular sealless magnetic drive pumps.

Some oil, gas and petrochemical applications that span the full hydrocarbon chain pose challenges to sealless pumps by creating magnetic losses that heat the process fluid. HMD Kontro overcome these challenges in sealless magnetic drive pumps by using containment shells, which eliminate eddy current losses in the pump, reduce energy consumption and enable sealed-to-sealless conversion.

Previous containment shells were made of metal, but the ZeroLoss Containment Shells are engineered from a composite material of poly-ether-ether-ketone (PEEK) and carbon fibre that was initially developed for military and aerospace equipment. Five times lighter than steel but just as strong, the ZeroLoss Shell increases the pump's reliability; provides greater efficiency; allows for temperature ranges from -40°C to +150°C; bolsters the pump's resistance to thermal shock; and eliminates potential vapourisation of process chemicals near the pump's bearing.

As a result, ZeroLoss Containment Shells enable HMD Kontro sealless magnetic drive pumps to resist a wider range of volatile and heat sensitive chemicals, and endure the rigours of a wider range of process applications.

“Tests by HMD Kontro have shown that installing a ZeroLoss containment shell in a sealless pump can result in a 20% reduction in power consumption,” said David Clark, General Manager at HMD Kontro Sealless Pumps. “The advantage increases in proportion with the magnetic coupling size and is particularly appropriate for larger pumps. These savings lower initial capital costs, by enabling smaller motors to be specified, and they also decrease total power costs over the life of the pump.”
