Ams Bianka Model Set 40 21 [work] May 2026

The 40/21 balances speed and volume. It can be cycled at 60–80 shots/min while delivering over 1.5 liters per minute—perfect for medium-scale production lines. As of 2025, the AMS Bianka Model Set 40/21 remains in production, though AMS components are often distributed through specialized industrial automation suppliers rather than mass-market channels.

$1,800 – $2,500 USD for the complete set (depending on seal material and nozzle configuration). Refurbished units can be found for $900–$1,400. The 40/21 balances speed and volume

Always use AMS-certified seals and pistons. Aftermarket parts often have slightly different tolerances, leading to leakage or scoring. | Model Set | Bore (mm) | Stroke

| Symptom | Possible Cause | Solution | |--------|----------------|----------| | Inconsistent shot size | Worn piston seals | Replace seal kit (AMS part #B21-40-SEAL). | | Material leaks from rear | Damaged rod seal | Disassemble, inspect rod for scoring, replace seal. | | Slow cycle rate | Low air pressure or clogged exhaust | Increase pneumatic pressure to 5 bar, clean silencers. | | Cavitation (air bubbles) | Insufficient feed pressure or material de-aerated | Increase reservoir pressure to 1.5 bar, vacuum-degas material. | | No dispense, but piston moves | Broken check valve or blocked nozzle | Remove nozzle, clean valve ball and seat with solvent. |

Whether you are bonding windshields, potting sensors, or dispensing grease into bearings, this model set provides a proven solution. Its 40mm bore and 21mm stroke hit the volumetric sweet spot for hundreds of applications. With proper maintenance—seal replacements, clean air supply, and periodic calibration—a single Bianka 40/21 can outlast the production line it was originally installed on.

In the world of industrial automation, fluid handling, and high-precision dispensing, few names carry the weight of consistency and engineering excellence as AMS (Advanced Manufacturing Systems). Among their extensive catalog of components, one product code that frequently surfaces in technical forums, parts lists, and maintenance manuals is the AMS Bianka Model Set 40/21 .
