The Imer Koine 35 Single Phase Mortar and Plaster Sprayer is a compact, high‑production continuous mixer and pump designed to mix, pump, and spray pre‑blended cementitious and gypsum‑based mortars, stucco, fireproofing, self‑leveling underlayments, and grouts using standard 220V single‑phase power. With up to 60 cubic feet per hour output and pumping distances up to 300 feet, the Koine 35 is built for contractors who need a versatile, portable mortar and plaster sprayer for interior, high‑rise, and large‑area projects.

Overview of the Imer Koine 35 Single Phase Mortar and Plaster Sprayer

The Imer Koine 35 is a continuous‑cycle mixing pump and sprayer: it automatically feeds dry pre‑mixed material from bags, mixes it with water, then pumps or sprays it through hoses with minimal labor. IMER and distributors describe it as “one of the most advanced and versatile production pumps on the market,” and “the only solution for the continuous mixing, spraying, and pumping of pre‑blended cementitious and gypsum‑based mortars, stucco, fireproofing, self‑leveling underlayments, and grouts.”

Unlike batch mixers and separate pumps, the Koine 35 integrates a feeding impeller, high‑shear mixer, eccentric screw (rotor/stator) pump, and water system into one compact, wheeled unit, which is especially useful for interior and high‑rise work where space and power are limited.

Key Specifications: Imer Koine 35 Single Phase

According to IMER spec sheets and leading distributors, the core specs for the single‑phase Koine 35 mortar and plaster sprayer (model 1106051 / 1106315 class) are:

• Power supply: 220V / 60 Hz, single‑phase

• Total machine power requirement: 5 HP

• Mixing and pumping (drive) motor: 3 HP

• Feeding impeller motor: 0.5 HP (1/2 HP)

Materials the Koine 35 Can Mix, Pump, and Spray

IMER Group describes the Koine 35 as a continuous‑cycle mixing pump suitable for pumping or spraying all dry pre‑mixed materials, including:

• Cement / lime / gypsum plaster‑based products

• Structural reinforcement mortars and structural plasters

• Restorative plasters and anti‑humidity plasters

• Stucco for interior and exterior applications

• Grouts and core‑fill grout

• Binders and mortars for injections

• Glues for thermal insulation coatings (EIFS/ETICS adhesives)

• Thermal insulating screeds based on cork or polystyrene

• Insulating plasters based on polystyrene or cork

• Fireproofing mortars (spray‑applied fireproofing)

• Self‑levelling cement‑based screeds and underlayments

ContractorsDirect and PDQuipment describe the Koine 35 specifically as a single‑phase mortar and plaster sprayer for dry pre‑mixed materials, with continuous mixing and pumping suitable for stucco, fireproofing, mortar, and grout, as well as self‑leveling underlayments.

In practice, the Koine 35 is often used for:

• Machine‑applying gypsum or cement plasters on walls and ceilings.

• Spraying stucco and fireproofing on large surface areas.

• Pumping self‑levelers across big floor plates.

• Pumping grouts and injection mortars on repair and structural jobs.

Continuous Mixing System and 4-Speed Flow Control

A key advantage of the Koine 35 Single Phase Mortar and Plaster Sprayer is its continuous mixing and variable‑flow capability.

System components:

• Star wheel / feeding impeller:

  • A continuous feed impeller blade (star wheel) meters dry pre‑blended material from the hopper into the mixing chamber, breaking up clumps and ensuring consistent feed.

• High‑shear mixer:

  • Inside the mixing chamber, the material is combined with water and mixed intensively before entering the pump.

• Eccentric screw pump (rotor/stator):

  • Standard stator and rotor (often D8 1.5 clamp) then draw the mixed material and push it into the hose at controlled pressures and flow rates.

• 4-speed inverter:

  • The control panel features IMER’s exclusive 4‑speed inverter (R2 or similar), allowing operators to select one of four material flow rates to match the product and application: roughly 34, 45, 53, or 60 cu ft/hr depending on the product sheet.

This continuous system means you can pour bags into the hopper while the machine mixes and pumps simultaneously, significantly reducing manual mixing, bucket handling, and downtime.

Water System, Flow Meter, and Mix Control

The Koine 35’s integrated water system is designed to deliver precise, adjustable water dosing for consistent mixes.

• Self‑priming water booster pump (stainless housing, brass impeller on many models) boosts line pressure and ensures reliable flow.

• Brass water system with flow meter and micrometric valve allows fine adjustment of water volume to match product specifications.

• Anti‑freeze discharge valve protects the water circuit in cold conditions (noted in IMER datasheets).

In the Koine 35, “the amount of water in the mixture can be viewed in the flow meter and can be adjusted according to the needs through a micrometric valve,” and mixed material is “immediately sucked by the eccentric screw pump and pushed into the pipe.” This gives consistent water‑to‑powder ratios batch after batch, critical for self‑levelers, plasters, and structural mortars.

Standard Equipment Included with the Koine 35

Typical standard equipment packages for the Imer Koine 35 Single Phase Mortar and Plaster Sprayer include:

• Dust grate with vacuum port (I-Dust grate) to limit airborne dust during bag loading.

• Standard mixer and mixing chamber.

• Stator and rotor D8 1.5 clamp (yellow) or equivalent, depending on configuration.

• Material delivery pressure gauge.

• Control panel with exclusive IMER 4‑speed inverter and diagnostic display.

• Self‑priming water booster pump.

• Complete brass water system with flow meter and anti‑freeze discharge.

• 20–66 ft (6–20 m) electric cable with plug, depending on region and package.

• 66 ft of water hose Ø 19 mm (3/4").

• 50 ft of material hose Ø 25 mm (1").

• Air hose (if compressor included) – often 16 m of Ø 13 mm.

• Spray gun with deflectors for plastering (standard on spray setups).

• Hose cleaning kit with toolbox and washing sponge.

• Mixing chamber clean‑out tool and scraper.

• Camlock adapters and rotor replacement wrench.

These standard inclusions mean the Koine 35 arrives essentially job‑ready: once connected to power, water, and (if spraying) an air compressor, you can start loading bags and applying material.

Optional Accessories and Setups

IMER’s spraying and pumping systems catalog lists a range of accessories to configure the Koine 35 for different materials and applications.

Examples include:

• Turbo mixer (1107517) for improved mixing of certain materials.

• Mixer for lightened materials (1107541) for thermal plasters, light screeds based on cork or polystyrene, and fireproofing.

• Alternative stator/rotor sets (e.g., D6‑3 orange) for specific viscosity and output needs (cement/lime/gypsum plasters, stucco, injection binders).

• Spray guns and wands:

  • Ø 25 F spray gun for traditional/premixed plaster.

  • 1.43 m overhead wand for fireproofing (1107549).

• Additional hoses, Camlock adapters, and hose cleaning sponges in different diameters.

These options let you tune the Koine 35 for high‑build plasters, insulating materials, fireproofing, or high‑flow SLU and grout applications as needed.

Portability and Jobsite Use

Despite its 510 lb weight, the Koine 35 is designed to be compact and portable for interior and high‑rise work.

• Footprint around 27" wide × 62" long makes it easy to position in corridors, rooms, and mechanical spaces.

• 36" loading height allows comfortable bag loading without excessive lifting.

• Wheel kit and balanced frame make it practical to move with two workers or a small material lift on multi‑story projects.

Because it runs on 220V single‑phase, it can often be powered from temporary panels or building power without needing 3‑phase service, which is a major advantage for many interior jobs.
