IMER – Koine DUAL | 208V 3 Phase & 220V Single Phase, 9 HP – 1106312 is a high‑output, continuous‑cycle mixing and pumping station designed to batch, mix, pump, and spray pre‑blended cementitious and gypsum‑based materials with maximum flexibility on modern jobsites. Its dual‑power capability lets you run on either 208V three phase or 240V single phase, delivering up to 9 HP total installed power and material flow rates up to 140 cubic feet per hour (up to 300 SLU bags per hour).

Overview: IMER Koine DUAL Continuous Mixer / Pump – 1106312

The IMER Koine DUAL is a continuous‑cycle mixing pump that takes bagged dry materials, mixes them with metered water in a high‑shear mixing chamber, and immediately pumps them through a rotor/stator pump into hoses for placement or spraying. Operators simply break bags into the hopper while the feeding wheel delivers dry material into the mixing chamber, where water is precisely dosed via a flow‑metered water system.

A high‑shear mixing paddle spins up to 400 RPM to thoroughly blend the mix before it discharges into the R8 stator/rotor, which generates pressure and moves material into the hose. A gear‑driven feed impeller ensures the material is fully wetted before it reaches the pump, improving consistency and reducing blockages. The “Dual” name reflects its ability to run on both 220–240V single phase and 208V three phase power, eliminating the need to choose one power type when purchasing.

Materials the Koine DUAL is Designed to Handle

IMER and IMER Group describe the Koine Dual as a variable‑speed continuous mixing pump suitable for pumping and spraying most dry premixed materials, including:

• Cement/lime/gypsum plaster‑based products

• Traditional and premixed plasters and stuccos

• Structural reinforcement mortars

• Anti‑humidity restorative plasters

• Insulating plasters based on polystyrene or cork

• Self‑leveling underlayments (SLU) and screeds

• Fireproofing and leveling materials within pumpable range

In practical jobsite terms, the Koine DUAL is ideal for:

• Large self‑leveling underlayment projects (interior and high‑rise).

• Continuous mixing and pumping of gypsum or cement plasters.

• Spray‑applied plasters, stuccos, and fireproofing when paired with a compressor and spray gun.

• Pumping structural or repair mortars where consistent, on‑demand material is needed.

The R8 stator/rotor supplied as standard is tuned for high‑volume cementitious and gypsum‑based mixes that require high throughput rather than extreme pressure.

Continuous Mixing System and High-Shear Turbo Mixer

The IMER – Koine DUAL | 208V 3 Phase & 220V Single Phase, 9 HP uses a multi‑stage mixing system designed for consistent products.

Process steps:

1. Dry material is poured into the hopper through a dust grate with integrated vacuum port.

2. A gear‑driven feeding wheel (impeller) meters the dry powder into the mixing chamber.

3. Metered water is injected through a self‑priming stainless steel pump and flow‑metered circuit with a micrometric valve to adjust water volume precisely.

4. A high‑shear mixing paddle (Turbo mixer kit included) spins up to 400 RPM to whip the material, ensuring complete wetting and homogenization before discharge into the R8 stator.

5. The helical rotor in the R8 stator generates pressure and pushes the thoroughly mixed material into the hose.

This inline high‑shear mixing approach is especially effective for SLU, plasters, and insulating plasters that must be lump‑free and consistent from batch to batch.

Dual Power Capability: 208V 3 Phase & 220–240V Single Phase

One of the standout features of the Koine DUAL is its dual power capability.

• It can be connected to 208V three‑phase power on commercial and industrial sites that have 3‑phase service.

• It can also run on 240V single‑phase power where three‑phase is not available (with the proper 32A circuits and wiring).

This flexibility means you don’t have to choose between a “single phase” or “three phase” model at purchase—one machine can be used across multiple types of sites and power conditions. IMER USA emphasizes that this eliminates guesswork and reduces fleet redundancy, making it attractive for rental fleets and contractors who work a mix of commercial and residential jobs.

Integrated Water System and Flow Control

The Koine DUAL’s water system is designed for precise and reliable control.

• Self‑priming stainless steel water pump (1 HP) pulls water from a tank or supply.

• Flow meter with clear readout shows water quantity in the mix.

• Micrometric valve allows fine adjustment of water flow to match manufacturer‑specified ratios for each product.

• “No freeze” discharge valve helps protect the water circuit in cold conditions.

Water is introduced at the correct point in the mixing chamber, and because the feed impeller and high‑shear mixer work together, the mix water is distributed quickly and evenly. Once set, the water ratio remains consistent as long as the hopper is fed at a steady rate, which is critical for SLU, plaster coats, and reinforcement mortars.

Additional mixing paddles and spray guns for light materials and different spray patterns are also available. This modularity lets you optimize the Koine DUAL for SLU, light insulation plasters, high‑build plasters, or controlled‑pressure injection work.

Dust Control, Hopper, and Loading Height

The Koine DUAL incorporates a dust grate with vacuum port over the hopper to address silica dust concerns.

• Dust grate: Covers the hopper opening and allows bag splitting while supporting the bags.

• Vacuum port: Connect a suitable dust extractor to capture airborne dust as powder is poured in.

With a loading height of 36 in, the hopper is set at a comfortable level for operators to load 50 lb or 80 lb bags throughout the day without excessive lifting strain. The hopper design accommodates breaking bags directly over the grate, making high‑volume feeding more efficient.

Dimensions, Portability, and Jobsite Setup

Despite its power, the Koine DUAL remains relatively compact:

• Width: 29 in – fits through standard 32–36 in doorways in many regions.

• Length: 47 in – compact enough for tight staging areas and high‑rise elevator transport (where size allows).

• Height: 62 in – manageable for interior floors and low overhead spaces.

• Weight: 574 lb – typically moved with pallet jacks, material lifts, or forklifts.

These dimensions make the IMER – Koine DUAL | 208V 3 Phase & 220V Single Phase, 9 HP practical for interior and high‑rise work where a stationary mixing/pumping station can be placed centrally and supply multiple rooms or zones via hoses.
