Part details
The green D8-1.5 stator is a genuine IMER part, part number 1107030. The IMER Small 50 parts book lists it in the Machine Structure table (ref. 9-A, ECO Monophase D.8-1.5), and the Koine 4 parts book lists it in the Mixing Chamber table (ref. 20, Stator D.8-1.5 DX ECO) for serial numbers 1106004 to 1106320. The IMER 2025 catalogue lists the D8-1.5 stator, part 1107030, on the Koine 3.1 applications page and notes that it requires manifold part 3223416.
Use it together with rotor 1107031. Our store lists these applications: pumping of grouts and self-leveling underlayments, spraying fireproofing, spraying mortar and stucco base coat (1/8 in or more of build-up), and waterproofing stucco and finish coat.
