TECHNICAL INFORMATION

Pump performance curves - OP chemical pumps

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

Horizontal pumps machined from a solid block of polypropylene (PP). All parts that come into contact with liquid (wetted parts), including nuts and bolts, are insensitive to corrosion.

ANTI-ACID PERFORMANCE

The anti-acid performance of Savino Barbera chemical pumps comprises casings, covers, impellers, shafts, mechanical seal and nuts and bolts. Just a few elements, which can always be easily removed.

Plastic pumps with heavy walled casing for a maximum chemical resistance

CAST-IRON MOTORS

Space-saving close-coupled plastic pumps. Equipped with cast-iron electric motors suitable for continuous running and heavy-duty operations.

EXTREMELY ROBUST

OP pumps are structurally and chemically very robust. Thanks to their flat plastic impellers and thick-walled plastic body, not only are they resistant to corrosion, they are also not affected by dirty liquids or high temperatures.

Savino Barbera chemical mechanical seal ideal for critical servcices

MECHANICAL SEAL

OP pumps are fitted with a mechanical seal resistant to corrosion and wear and tear, compatible with most industrial liquids. This seal is the product of years of experience working with chemicals and consists of just a few elements: a coated spring, a bellows made of PTFE and two sliding rings that create the seal. It has no metal parts in contact with aggressive liquids. Furthermore, it requires no special adjustments or tools to be used or mounted: simplicity is its strength!

THE DETAILS THAT MAKE THE DIFFERENCE

All-plastic robust impellers totally resistant to corrosion

POLYPROPYLENE

The plastic construction material used to make OP chemical pumps is polypropylene (PP), a thermoplastic used extensively with industrial fluids which offers good resistance to most acid and alkaline solutions. Polypropylene can be used, depending on the concentration of the aggressive liquids, at temperatures of up to 80°C.

Savino Barbera corrosion-free mechanical seal

MECHANICAL SEAL

OP horizontal pumps are fitted with a corrosion-resistant mechanical seal designed exclusively by Savino Barbera. It is an internal mechanical seal, balanced with bellows independent of the direction of rotation. It is flushed by the liquid being pumped. The material used as standard, for the OP series only, is usually silicon carbide (SiC).

Pump bodies machined from solid for harsh and highly corrosive applications

EXTRA THICK

OP chemical pumps are engineered for harshest of environments and for continuous running (even 24 hours a day). They are suitable for a variety of industrial applications, including wet cleaning towers, scrubbers, deodorising systems, fume and odour control systems, ash inertisation plants and evaporation towers.

Non-metallic impellers constructed of polypropylene

FOR DEMANDING OPERATIONS

The horizontal chemical pumps of the OP series are equipped with cast-iron 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.
