ASAB S Series - S1/S3 Replacement Ceramic Cylinder

The ASAB S1/S3 Ceramic Cylinder is a premium pump wear component engineered for the ceramic piston pump used across the S1 and S3 platforms. Ceramic delivers exceptional wear resistance and maintains a smooth sealing surface under load—supporting consistent pressure, reliable prime, and stable delivery over long service intervals. It’s the correct replacement when the pump cylinder surface is worn, scored, or no longer sealing efficiently.

Key benefits

• High-wear fully ceramic construction for extended service life in regular-use machines

• Restores pressure stability to reduce pulsing and improve spray consistency

• Improves prime and pressure hold by returning the pump’s sealing surface to specification

• Protects packings and piston components by replacing a worn cylinder before accelerated wear occurs

• Built to suit S1 / S3 piston pump assemblies

Service and fitment notes

• Suits ASAB S1 & S3 Series ceramic piston pump configurations.

• Replace if you find scoring, chipping, pitting, loss of prime, poor pressure hold, or rapid packing wear.

• Best practice during replacement: inspect/refresh packings, piston rod condition, ball/seat valves, and inlet filtration to ensure correct bedding-in and maximum lifespan.

Safety Check
Before any fluid section work, complete full pressure relief: power off, engage gun safety, trigger into a grounded waste bucket, and open the prime/bleed valve. Wear eye protection and gloves, and never work on a pressurised system—fluid injection injuries are a medical emergency.
