MAGNETIC DRIVE COUPLING
SEALLESS PUMPS
The absence of dynamic seals and magnetic coupling between pump and motor, at least virtually, prevent external leakage. Their maintenance, however, is usually more expensive than with pumps with mechanical seals.
CONTACT-FREE
The external magnet, coupled to the motor shaft, conveys movement to the internal magnet which is attached to the impeller. As the motor shaft does not extend inside the pump body, the contact-free magnetic pump is incapsulated and protected from corrosion.
CLEAN LIQUIDS ALWAYS
The thin plastic coating of the magnets and the closed channels of the impellers do not withstand liquids with abrasive solids and suspended particles, especially when metallic. Over-saturated liquids could also pose a problem for magnetic pumps.
HIGH-CHEMICAL RESISTANCE
Savino Barbera magnetically driven pumps mount closed impellers, made of corrosion-resistant plastic. The anti-acid thermoplastic materials used foe are PP and PVDF.

SEALED PUMPS VS MAGNETIC PUMPS
Magnetic pumps are considered to be hermetically sealed pumps. Their presumed tightness must be scrupulously evaluated in relation to the characteristics of the liquid being pumped. The choice of mag-drive pumps can be influenced by incorrect installation habits rather than by real technical needs. Magnetically coupled pumps are often preferred to mechanically sealed pumps in the belief that the former are safer, but their use requires particular attention to specific working conditions.
CONSTRUCTION MATERIALS
PP (POLYPROPYLENE)
The most widely used thermoplastic polymer for the construction of anti-acid centrifugal pumps. It offers good resistance to most acid and alkaline solutions and can be used, depending on the concentration of the aggressive liquids, at temperatures of up to 80°C.
PVDF (POLYVINYLDENFLUORIDE)
Fluorinated thermoplastic with exceptional resistance to corrosion and temperature. PVDF covers a wide range of uses but is ideal for highly concentrated acids. It is not suitable for certain inorganic bases, such as caustic soda. Operating temperature: max. 100°C
