Design UPA
Single- or multistage centrifugal pumps in ring-section design, single entry; for vertical and – depending on the number of stages – horizontal installation; radial or mixed flow hydraulic systems available with reduced impeller diameters; driven by asynchronous motor or high-efficiency, synchronous submersible motor; suction casing fitted between pump and motor, suction casing equipped with strainer to protect the pump from coarse particles in the fluid handled. Pumps with check valve or connection branch on option.
Applications Pump UPA
