TECHNICAL INFORMATION
Standard curves: 50 Hz (60 Hz curves available on request). A-B series: open impeller. D series: 4-pole motor. E series: 2 or 4-pole motor. 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.

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
GP vertical pumps are made of corrosion-resistant thermoplastic material (polypropylene). 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 completely anti-acid performance of our pumps also comprises nuts and bolts and pump shafts, metallic elements protected from corrosion by plastic coating in PP. Savino Barbera design eliminates the direct contact of metal with aggressive liquids.
END BUSHINGS
Sliding bushings with direct flushing, with no need for external lubrication. The standard version of pump bushings (external bushing) is made of SiC, a material with excellent resistance to wear and tear, and a low expansion and friction coefficient.
MODULAR DESIGN
Construction without predefined lengths, suited to any depth up to 3000 mm. Extra thick PVC support plates, also available in custom-made shapes and sizes. Delivery connection: DN80 or DN100 flange
CHEMICAL RESISTANCE
Machined from a solid block of polypropylene, GP centrifugal pump casings are structurally and chemically very robust. Thanks to their thick-walled plastic body, not only are they highly resistant to corrosion, they are also not affected by dirty liquids or high temperatures.
PLASTIC IMPELLERS
Plastic impellers with no metal inserts: resistant to attack from acid, even on the inside. Wide internal gaps facilitate the passage of coarse solids and the pumping of charged liquids.

EXTREMELY ROBUST
GP plastic pumps are characterised by excellent hydraulic performance (flow rate and head). Their volute pump casing, machined from a solid block of material, guarantees excellent chemical and mechanical resistance. Moreover, their compact dimensions and flat impellers facilitate use in tanks that are shallow or have a reduced capacity, such as in wet fume control systems.
THE DETAILS THAT MAKE THE DIFFERENCE
REINFORCEMENT IN FIBREGLASS
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.
WEAR BUSHINGS
GP pumps have no intermediate bearings, even in the longer versions (3000 mm). The only guide element consists of a pair of wear 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.
FILTERS AND EXTENSIONS
GP pumps can be fitted with suction extensions to reach extra lengths of 4 metres. They can also be equipped with filters to trap coarse impurities; the grill prevents the suction of residues or foreign bodies that are often found in industrial liquids. The filters are also available in a flat version to reduce the occupation of the bottom of the tank.
FOR DEMANDING OPERATIONS
The vertical pumps of the GP series are equipped with motors with oversized bearings (double row angular contact ball bearings) and PP fans resistant to acid vapours. These qualities make them particularly well-suited to heavy-duty services and continuous operations.
