The stable and repeatable feeding of powder is the foundation of every successful powder coating line. Gema offers two generations of solutions: modern dense-phase powder pumps and classic Venturi injectors. Both are optimised for fast colour changes, low operating costs and maximum powder utilisation efficiency.
Why choose Gema powder pumps?
- Gentle powder handling – dense-phase technology moves powder at low velocity and keeps the grains intact.
- Stable and repeatable flow – consistent film thickness even in long production cycles.
- Fast colour change – straight powder paths and quick couplings reduce downtime.
- Fewer wear parts and easy maintenance – tool-free replaceable parts shorten downtime.
- Energy and powder savings – lower air consumption and less overspray.
Gema model range
Powder pumps
- OptiSpray AP02 – new-generation dense-phase powder pump with PowerBoost®, PCC and DVC technologies. Top-level coating result and stability.
- OptiSpray All-in-One – dense-phase powder feeding and charging in a single unit. Best coating result and fastest response time.
Injector technology
- OptiStar All-in-One® – electrostatics and powder feeding in one compact unit. Fastest response to ensure maximum coating efficiency.
- OptiFlow IG07 (manual spraying) – new-generation inline injector for stable powder flow and optimised colour change.
- OptiFlow IG07-PA (automatic spraying) – the same IG07 technology for automatic coating.
Powder transfer systems
- OptiFeed 4.0 – smart powder transfer solution (Connect – Transfer – Control). Automated powder feeding from a box, drum or big bag.
Powder pump or Venturi injector – which to choose?
As a general rule, a powder pump (AP02, All-in-One) delivers the best results for demanding surface finishes, hard-to-charge powders and long production cycles. Injector solutions (IG07, OptiStar) are well suited to standard applications where simplicity and low acquisition cost are important. We will help you choose the best solution for your specific process.
