Dosing / Wobble Stator

General Description

The AP Line is our progressive cavity pump built around wobble stator technology. By using a single universal joint, it achieves a mechanically simpler design that drastically cuts both acquisition and maintenance costs.

It's the best-value option on the market for dosing and sampling applications, delivering continuous pumping that's free of pulsation and shear. Available in monoblock (direct-coupled) or free-shaft versions.

  • Water Treatment: Injection of polymers and flocculants.
  • Chemical Industry: Additive dosing and chemical reagent feed.
  • Analytical Systems: Sampling and precision dosing.
  • Fluid Handling: Transfer of liquids with suspended solids.

The wobble stator design eliminates one of the pump's universal joints, fixing the stator at a single point. This lets the stator "wobble" in sync with the rotor's rotation, reducing wear, minimizing the footprint required, and lowering spare-parts replacement costs.

Why choose the AP Line?
Simplicity: Just one universal joint and few moving parts, which makes maintenance easier.
Fluid Protection: Smooth, low-shear pumping that doesn't degrade sensitive polymers.
Cost-Effectiveness: The most economical option on the market for continuous industrial dosing.
