vertical stainless steel pumps MXV-B
Pump design
Multistage monoblock vertical pumps Calpeda MXV-B with suction and delivery sockets located on the same shaft in multi-row design. The sockets have the same diameter.
The guide bushings are lubricated by the pumped liquid and are absolutely resistant to corrosion. The wetted parts of the Calpeda MXV-B pump are typically made from chromium-nickel stainless steel.
Pump applications
Water supply.
The Calpeda MXV-B multistage monobloc vertical pumps are considered universal because they are excellent for use in domestic and industrial applications: high pressure washers, pressure boosters, irrigation systems, fire fighting devices, sports facilities and agriculture.
Calpeda MXV-B pumps are used for pumping non-explosive clean liquids that do not contain fibrous/abrasive/solid impurities that are not directly aggressive to stainless steel. If necessary, a seal made of a special material is installed.
