Closed type impeller with front and rear wear rings as well as balancing holes, to minimise the axial thrust.
Large eye single suction 1st. stage impeller to meet low NPSH requirements.
Deep stuffing boxes, designed in accordance to API 682 Std., suitable to accept any type of mechanical or packing seal.
Labyrinths and deflectors at either bearing housing to maximise protection against dirt.
A wide range of sizes and material combinations complete the variety of the offered product.

As a standard, the rotor axial thrust is supported by a duplex oil lubricated ball angular contact type bearings.
Discharge column, line shaft and support column may consist of multiple sections, depending upon the pump setting. Discharge column mounted with a sliding fit through the sole plate to account for thermal expansions.
Renewable intermediate bushings, lubricated by the same pumped fluid or from an external source, are provided in correspondence of all column sections.
