The IMER Koine Dual (Model # 1106312) is a high-flow continuous mixer pump for preblended cementitious materials. Its name comes from its ability to run on single phase or 3 phase power. Bags are broken directly into the hopper, a gear-driven feed impeller delivers the dry material into the mixing chamber, and metered water is added. A high-shear paddle turning up to 400 RPM mixes the material before the R8 rotor and stator push it into the hose.

The drive motor is rated 7.5 hp, with 9 hp total machine power. Material flow reaches up to 140 cu ft/hr, or 275 bags per hour of underlayment or similar bagged product. On 3 phase 208V it runs at full power, with inverter control offering 8 speeds and soft start; on 240V single phase it runs up to speed 7 of 8. Loading height is 36 in and the machine weighs 574 lb.

Standard equipment includes a dust grate with vacuum port, turbo mixer kit, material delivery pressure gauge, self-priming water pump, water system with flow meter, 33 ft of 1-3/8 in (35 mm) material hose with quick connects, an integrated tool storage box and a clean-up kit.
