Pump components geometry, optimised through hydraulic, structural, thermal and dynamic F.E.M. analysis, lead to an high product reliability.
To minimise floor space requirements, bearing housing and motor baseframe are vertically mounted on casing directly bolted on a foundation plate.
Twin volutes ( for sizes with discharge nozzle > 2" ) minimise radial loads for extended pump life.
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.
Back pull-out design allows all pump maintenance activities without motor removal.
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.

Main design features

Fully designed according to latest edition of API 610 Std
In-line arrangement for suction and discharge nozzles integrally cast with the casing.
Rotor operates away it’s critical speeds.
Air fan cooling system provided on bearing bracket and /or mechanical seal when required by hot temperature applications.
As a standard, the rotor axial thrust is supported by a duplex oil lubricated ball angular contact type bearings.
