TECHNICAL INFORMATION

pump-performance-curves-oma-chemical-pumps

Standard curves: 50 Hz (60 Hz curves available on request). A-B series: open impeller. C series: closed impeller. 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

PLASTIC IMPELLERS

Plastic impellers with no metal inserts: resistant to attack from acid, even on the inside. The resistance stems from thick walls and pure plastic materials chosen depending on the chemical liquids to be pumped.

MECHANICAL SEAL

The anti-acid performance of our chemical pumps also comprises the mechanical seal, which is completely insensitive to corrosion. Consisting of just three elements, it requires no adjustment or regulation with screws.

SPACE-SAVING DESIGN

Reduced components and minimum space requirements outside the tank. The suction and delivery connections can be: hose adapters, threaded connections or flanges.

LESS METAL, LESS CORROSION

OMA horizontal pumps are made of corrosion-resistant plastic material (PP, PVC, PVDF). All wetted parts are insensitive to corrosion and are built with maintenance in mind, using simplified components which can be easily removed over time.

MECHANICAL SEAL

OMA 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!

OPTIONS THAT MAKE A DIFFERENCE

PP chemical pump trolley mounted for added mobility

TROLLEY-MOUNTED PUMPS

The close-coupled construction of Savino Barbera’s horizontal centrifugal pumps makes them easy to mount on wheels. Transformed into practical portable units, the trolley-mounted pumps can reach the most awkward corners of your systems for use in quick operations, occasional jobs and emergency operations (like filling and emptying tankers or emptying tanks in places far away from pipes or other fixed installations). The transport trolley is a powder- painted steel structure with a handle and with rubber and polypropylene wheels, to ensure silent movement and prevent damage to the floor.

DOUBLE MECHANICAL SEAL

OMA pumps are also available with double mechanical seal flushed by liquids: with this execution, the traditional features of the conventional single seal (product side) are joined by the advantages of a secondary seal (atmosphere side). The double seal allows the plastic pump to work in critical conditions and even when there is no liquid (dry running). This solution prevents the seal faces from sticking and facilitates the pumping of liquids at very low temperatures, with crystals, oxides or solid deposits. Consequently, it represents an additional safety mechanism against dry starting or the formation of scale.

All-plastic horizontal pump anchored on a PVC baseplate

BASEPLATES

Baseplates for assembly with pumps equipped with B3/B5 motors. They allow perfect horizontal alignment with the system. OMA chemical pumps can be anchored to various types of baseplates: single support feet made of PVC or stainless steel to secure the motor only, or large PVC baseplates to support the entire pumping unit. The plastic baseplates are extra thick (PVC sheets with a maximum thickness of 70 mm, for larger pumps), with standard dimensions and pre-drilled holes. However, they can also be custom-made if special sizes and shapes are required.
