Overview of the IMER Koine 3.1 Continuous Mixer / Pump

The IMER Koine 3.1 is a continuous mixer, pump, and sprayer built to simplify high‑production interior and exterior finishing work. In dry mode, you feed bagged premixed material (like SLU, grout, or mortar) into the hopper, where it is automatically mixed with water and pumped through a hose to the application point. In wet mode, you use a separate mixer such as the IMER Mix 120 Plus to premix material with additives, then pour it into the Koine 3.1 hopper and use the unit as a powerful pump only.

This dual‑mode flexibility means the IMER – Koine 3.1 | 4.5 HP, 240V Single Phase – 1106351 can handle simple bag‑and‑pour applications and more complex mixes that require longer mixing times or specialty additives. Its compact footprint, 12 in wheels, and 350 lb weight make it highly portable and suitable for high‑rise and interior work where access is tight.

Materials the Koine 3.1 is Designed to Handle

IMER specifically designed the Koine 3.1 to process a wide range of pre‑blended, pumpable materials:

• Cementitious self‑leveling underlayments (SLU) and toppings

• Gypsum‑based self‑levelers and plasters

• Pre‑blended masonry mortars and stuccos

• Fireproofing materials (cementitious and gypsum‑based)

• Cementitious and gypsum grouts

• Fine mortars and repair mortars

StoneTooling notes that the Koine 3.1 is “capable of continuous mixing, spraying, and pumping of pre‑blended cementitious and gypsum‑based mortars, stucco, fireproofing, self‑leveling underlayments, and grouts,” and that it can mix and pump both dry and wet materials. IMER USA confirms that it is designed to be a continuous pump for dry bagged products, with the option to use wet mode when extended mixing is needed.

This makes the IMER – Koine 3.1 | 4.5 HP, 240V Single Phase – 1106351 a versatile solution for flooring contractors, plasterers, stucco crews, fireproofing specialists, and repair contractors.

Continuous Mixing and Pumping System (Dry Mode)

In dry mode, the Koine 3.1 works as a continuous mixer / pump:

1. Bagged premixed material is dumped into the hopper through the grated opening.

2. A horizontal mixing chamber and paddle system blend the dry material with water from the integrated water system.

3. Mixed material is fed into the D8‑1.5 stator/rotor pump section and pumped out through the 1 in material hose.

Flow rates in dry mode range from 1/4 to 3/5 cu ft per minute, depending on pumping speed and material viscosity. The Koine 3.1 features 6 selectable speeds in dry mode, allowing you to increase or decrease output and power draw to match the available electrical supply and job needs.

An integrated self‑priming water booster pump, flow meter, and discharge valves provide precise water dosing and stable pressure, which is critical for maintaining consistent mix quality for SLU and grouts.

Wet Mode Operation: Pump Only

In wet mode, the Koine 3.1 acts as a pump only. Instead of mixing inside the Koine itself, you:

• Mix the product separately in a vertical shaft mixer like the IMER Mix 120 Plus or Mix 200 FP when longer mixing times or complex additives are needed.

• Pour the fully mixed material into the Koine 3.1 hopper.

• Use the adjustable pumping speed to deliver material to the hose outlet.

Wet‑mode flow ranges from approximately 0.08 to 3/5 cu ft/min and is controlled by progressive speed adjustment in wet mode via the inverter and interactive display. This setup is ideal for specialty self‑levelers, engineered mortars, and fireproofing mixes where manufacturer specifications demand extended mixing times or precise additive incorporation.

Control Panel, Inverter, and Interactive Display

One of the standout features of the IMER – Koine 3.1 | 4.5 HP, 240V Single Phase – 1106351 is its advanced control panel with IMER A1 inverter and interactive display.

Key control features:

• Easy Start system that prevents motor blocking on startup, even when material is present.

• IMER A1 inverter with 6 selectable speeds in dry mode and progressive speed adjustment in wet mode, allowing you to adapt power draw and pumping rate to site power availability.

• Interactive alphanumeric display providing visual and acoustic diagnostics (e.g., H2O, BLOCC, STOP, ERR08), making operation simple even for less experienced operators.

• Remote‑control readiness so operators can control pumping from the application site (with appropriate accessories).

This control system helps prevent overloads, simplifies troubleshooting, and allows you to fine‑tune performance for different materials and job conditions.

Safety Features and Compact Design

The Koine 3.1 is designed with safety protections that stop the electric motors when the hopper grid is removed or when the mixer motor section is opened or tilted. This prevents accidental contact with moving parts during loading or cleaning.

Additional safety and design highlights:

• Small footprint and 350 lb weight, with 12 in wheels for easy handling on uneven terrain and in confined areas.

• Integrated compressor on some versions and easily removable on Koine 3.1 Coat variants (European spec), ensuring flexibility for different applications.

• Noise levels below 76 dB(A), making it suitable for interior work and occupied buildings.

These features, combined with the diagnostic display and Easy Start system, make the machine user‑friendly and safe for crews with varying levels of pump experience.
