HMS DeLium double suction pumps

HMS DeLium double suction pumps

The HMS DeLium is a new generation of the double suction pumps with axially split volute casing designed by contemporary computer modeling techniques with consideration of the modern requirements to energy consumption and reliability.

A wide model range and application of at least two interchangeable impellers for one casing size enables to choose a pump for any customer requirements within up to 10,000 m3/h capacity up to 200 m pressure head.

The pumps can be operated in parallel and regulated by the variable speed drives.

The climatic conditions admit application of the pumps within -60°С to +60°С temperature range.


Water supply, treatment and heating systems, oil & gas, nuclear & thermal power, chemical industry, pulp & paper, general industrial processes, agriculture & irrigation, firefighting, desalination, shipbuilding.
