Product Description
Garbarino's multistage pumps family has been widely tested over the years in applications with pressures up to 40 bar. Now, with the newly developed GH pumps, we can achieve pressures to 75 bar and capacities to 500 m3/h.
APPLICATIONS
These pumps are suitable for applications mainly in power and desalination plants, for boiler feeding and reverse osmosis respectively. Moreover they can be used in other fields such as snowmaking equipment, marine and offshore industries for water mist fire fighting services and others.
CONSTRUCTION
The GH design is the newest in the industry, we have used an entirely new approach to hydraulics and mechanics for high pressure pumps. The range of GH pumps includes 4 sizes (50-65-100-150) with 8 different hydraulic systems to insure that every client demand can be met. The pumps are multistage, horizontal pumps radially split with impellers assembled between external bearings.
The main features are:
- feet cast with suction unit and delivery for greater rigidity and strength
- UNI-DIN-ANSI-JIS-ISO standard flange connections
- suction flange rotating to three positions
- high efficiency enclosed type impellers with low NPSH suction impeller
- replaceable wear rings
- oil-sealed external bearings with constant level olier
- drum-type balancing device for axial thrust
- oversized shaft for minimal deflection
TECHNICAL FEATURES
- maximum capacity 500 m3/h
- maximum head 750 m
- maximum speed 3600 rpm, lowest critical speed over 5000 rpm
- single or double mechanical seal (balanced type)
- optional seal cooling
GH pumps can be supplied in a range of metals to offer custom compatibility with pumped liquid, another appealing feature of the pumps. The base version has a nodular cast iron body (GS600) and G25 cast iron impellers, but special stainless steel pumps are available, such as AISI 316, Duplex, Superduplex, Hastelloy B and C, Monel, Alloy 20 and others.
