Stainless steel vertical pumps

Three models have been added to the DP-Pumps range of vertical multi-phase in-line centrifugal pumps. The range uses stainless steel for all components in contact with the pumped medium. This gives the pumps a longer service life and enhanced performance and hygiene, says the company. The O-ring seal of the pump sleeve is designed to resist temperature fluctuations and avoid leakage, and the mechanical shaft seal conforms with DIN 24960, says DP-Pumps.

The pumps have a deep-drawn and welded pump-foot and the DPVS series is available with internal-thread flanges or with victaulic connections.

Both the DPV and DPVL series are interchangeable with DP-Pumps` DPL and DPLS series, and with other commercially available pumps. Impeller numbers vary from 1 to 20 and the maximum capacity is 24 m3/hr.

Applications include process and potable water pressurisation-systems, boiler feeds, sprinkler systems, climate-conditioning systems, fire-fighting systems, water-treatment systems, cooling water transmission, and cutting oil transmission in the metal working industry.
