Standardised single-stage cast iron centrifugal pump and electric pump which combines the best technical and performance features in a single solution.

The wide range (from DN 32 up to DN 200-500), the variety of materials available, the easy maintenance and the hydraulic efficiency, are further enhanced by the interaction with the electronic solutions also offered by EBARA.

The GS models are available in both bare shaft and electric pump versions, with the following technical features:

• Robust cast iron pump body
• Impellers available in cast iron, ductile cast iron and bronze

The seal can be selected in two different versions: the mechanical one in Silicon Carbide/Carbon/EPDM and the packing one, in Silicon Carbide fibre. It has two replaceable bronze wear rings that ensure long-term reliable operation and high hydraulic efficiency.

Finally the flanges, from DN 32 up to DN 200, all PN16 (with reference to EN 1092-1), make GS a product suitable for the heaviest and most demanding applications.

The motors are available with 2 or 4 poles, 50 Hz, with IE3 efficiency (from 0.75 kW), with powers ranging from 0.37 kW to 355 kW, which can be coupled with inverters.
