Description
The Travaini monostage centrifugal pumps of the MCU-CH series are principally for chemical and petrochemical applications and used on almost all the plants. The new design and the wide sizing of the bearing housings allows high reliability and minimum maintenance while the special design of hydraulic profiles for the impeller and the casing allows to reach high efficiencies and low NPSH in any application.
The Travaini monostage centrifugal pumps of the MCU-CH series are standardized according to ISO 2858/DIN 24256 standards and the manufacturing program includes three bearing frame sizes of the “Back pull-out” type; the pump casing is of the spiral type with axial suction flange; the impeller is of the radial type with overhang mounting. The whole Travaini production is guaranteed by certified quality system according to ISO 9001 standards.
