    AI Overview
    The Gema IG02 (OptiFlow) is a widely used powder injector pump designed for electrostatic powder coating systems, particularly the OptiFlex 2 and OptiSelect GM02 series. It is responsible for transporting powder from the hopper to the gun, using a Venturi effect to create a precise, consistent flow. 
    This video explains how the OptiFlow injector works and how to replace its wear parts:

    • Model: IG02 (OptiFlow)

    • Compatibility: Designed for Gema OptiFlex 2, OptiSelect GM02, and GA02 automatic guns.
    • Components: Includes a powder injector body, insert sleeve (venturi tube), check valve, and hose connection.
    • Material: Often constructed with wear-resistant PTFE inserts for the venturi tube.
    • Performance: Designed to reduce material waste with high transfer efficiency.

    Maintenance and Spare Parts 
    The IG02 injector has several wearing parts that need periodic replacement to maintain performance, including: 
    • Insert Sleeve (Venturi Tube): Part #377 724
    • Check Valve (Red/Back): Part #103 012
    • Nozzle: Part #103 500 
    Regular cleaning of the injector body and replacing the PTFE insert sleeve ensures consistent coating quality and prevents clogging. 
    If you're looking to purchase, would you prefer an original Gema part or a cost-effective aftermarket replacement? Let me know if you need help finding specific spare parts like the insert sleeve or check valves.
