Nowadays, reciprocating pumps increasingly utilise ceramic pistons, which offer significant advantages in terms of performance, operating conditions and stability, making them a common solution for industry upgrades.

Longer service life

Ceramic materials are highly hard and far more wear-resistant than ordinary metals; they are resistant to wear and scratches even during prolonged reciprocating motion. This significantly extends replacement intervals, reduces downtime for maintenance and enhances the overall durability of the equipment.

Suitable for harsh operating conditions

Ceramic materials possess stable chemical properties, offering resistance to acids, alkalis, sewage and various corrosive media; they do not rust or corrode. They operate reliably in complex environments such as chemical processing, wastewater treatment and mining, making them suitable for a wider range of applications.

More Stable Operation

Ceramics have a low coefficient of thermal expansion, meaning they are resistant to deformation under high-temperature and high-pressure conditions, maintaining dimensional stability. As temperature fluctuations do not affect clearance tolerances, equipment operates more smoothly and with a lower failure rate.
