- Extensive internal clearance and recessed non-clogging impeller.
TECHNICAL INFORMATION
Standard curves: 50 Hz (60 Hz curves available on request). The curves refer to tests with cold, clean water and a density of 1000 kg/m³ (ISO9906). Hydraulic performance may change in relation to changes in the characteristics of the liquid to be pumped.
| Q max m³/h | H max m w.c. | kW | rpm 50 Hz | Min-Max length | Datasheet | |
|---|---|---|---|---|---|---|
| GA20 | 6.2 | 7 | 0.37 - 0.55 | 2900 | 250 - 1000 mm |  |
| GA30 | 12 | 10 | 1.5 - 2.2 | 2900 | 320 - 3000 mm | |
| GA40 | 23 | 18 | 2.2 - 3 | 2900 | 320 - 3000 mm | |
| GA50 | 44 | 20 | 4 - 5.5 | 2900 | 435 - 3000 mm | |
Savino Barbera also manufactures custom pumps outside this production range: the table does not indicate all the possible combinations of impellers and motors. It is possible to install various types of impeller and motors with non-standard powers, voltages, frequencies and protections. Please contact our technical department for any special requirements.

STRENGTHS
LESS METAL, LESS CORROSION
BS vertical pumps are made of corrosion-resistant thermoplastic material (PP, PVC, PVDF). All wetted parts are insensitive to corrosion and consist of just a few elements, which can be easily removed over time.
ANTI-ACID PERFORMANCE
The anti-acid performance of our pumps also comprises all nuts and bolts and pump shafts, metallic elements protected from corrosion by plastic coatings (PP, PVC, PVDF). Savino Barbera design eliminates the contact of metal with aggressive liquids.
WITH AND WITHOUT BUSHINGS
Version with sliding bushings: pump-shaft equipped with bushings with no need for external lubrication. Version without bushings (cantilever): completely cantilevered pump-shaft, suitable for charged liquids or cases in which there is a very high risk of running dry.
MODULAR DESIGN
Version with bushings: custom-made lengths up to 3000 mm. Version without bushings (cantilever): Four fixed lengths (400, 550, 700, 900 mm). Connections: thread, hose adapter or flange.
DRY-RUNNING
GA pumps, in the version without end bushings, have the ability to run dry without problems, eliminating a classic limit of all plastic pumps. The absence of bushings makes it suitable for use even in the absence of liquid.
COARSE SOLIDS AND FILAMENTS
Extensive internal clearance and non-clogging impeller: features that facilitate the pumping of aggressive liquids containing foreign bodies, fibres or other impurities found in many industrial fluids.

DRY RUNNING!
The recessed non-clogging impeller and clearance inside the pump-casing make the GA a perfect chemical pump for extreme use, such as the handling of liquids containing suspended solids or (in the cantilever version only) when there is a risk of running dry. In this last case, GA Plastic pumps can be used to prevent the problems that occur when the liquid no longer reaches the pump for some reason.
THE DETAILS THAT MAKE THE DIFFERENCE
FRP REINFORCEMENT
From lengths of 2000 mm upwards, Savino Barbera vertical pumps have aluminium motor supports, oversized shafts and fibreglass outer structures. This is a construction solution that ensures additional resistance to vibrations while protecting the pump from other mechanical or thermal stress.
VERSION WITH BUSHINGS
In the supported shaft versions, the only guide element of GA pumps consists of a pair of bushings positioned at the end of the pump shaft. The bushings are available in materials suited to chemical liquids, fluids containing sludge or suspended solids: filled-PTFE, sintered ceramic or silicon carbide.
DELIVERY CONNECTIONS
The delivery connections of GA vertical pumps are available in three versions: threaded, hose adapter or flange. There are no extra charges for the optional features. In the event of particular requirements, special connections, lowered deliveries or flanges with ANSI 150 drilling can be mounted.
