The Imer Purple Stator is a genuine IMER D‑series stator (part 1107084) for rotor/stator pumps like the Mighty Small 50, Koine 35, and Koine 4, engineered to deliver lower flow but higher pressure than standard green stators so you can pump stiffer mixes, fine mortars, and tuckpointing materials with more control. As a quick‑change wear part in IMER’s progressive cavity pump system, the Imer Purple Stator is the heart of a D5‑2.5 pumping setup, providing precise, steady output ideal for specialty applications like tuckpointing, repair mortars, and detailed restoration work.

What is the Imer Purple Stator?

Suppliers list this part as:

  • “1107084 Imer Purple Stator Screw” – Contractors Direct.

  • “Imer Purple Stator D5‑2.5 – 1107084” – Master Wholesale.

  • “IMER 1107084 | 2.5 Purple Stator D5” – Vovlift. 

  • “Imer Purple Stator – SKU 1107084” – Blades Direct.

It is a D‑series stator sized for a D5‑2.5 rotor/stator combination, used in IMER rotor/stator pumps. The stator is the stationary rubber‑lined cylinder that the steel rotor turns inside; together they form a progressive cavity that moves material smoothly through the pump.

Key identifiers:

  • IMER part number / SKU: 1107084.

  • Description: Purple stator, D5‑2.5 (often called simply “Imer Purple Stator”).

  • Color code: Purple, indicating low‑flow, high‑pressure configuration vs. green stator.

Compatible IMER Pumps: Small 50, Koine 35, Koine 4

The Imer Purple Stator is designed to fit several IMER rotor/stator pumps. Contractors Direct states:

  • “Stator ONLY, purple, for Small 50, Koine 4, Koine 35.”

Blades Direct and Vovlift also tag it for use with Mighty Small 50, Koine 35, and Koine 4 pump systems.

In IMER’s own rotor/stator pump lineup:

  • Mighty Small 50 is the compact multi‑purpose pump for plasters, mortars, fireproofing, and tuckpointing.

  • Koine 35 and Koine 4 are continuous mixer‑pumps for pre‑blended products, capable of high‑reach and long‑hose pumping.

On these machines, the Purple Stator D5‑2.5 works together with the matching Purple Rotor D5‑2.5 (1107085) to create a low‑flow, high‑pressure pumping configuration.

Flow and Pressure Characteristics: Purple vs Green

The Purple Stator is specifically tuned to deliver lower flow and higher pressure than IMER’s standard green stator:

Contractors Direct:

  • “Gives lower flow but higher pressure than green 2L3.”

Blades Direct on the matching rotor:

  • “Gives lower flow but higher pressure than green 2L3; goes with purple stator part # 1107084.”

ConSpec’s IMER Small 50 configuration sheet quantifies this:

  • Purple stator: 0.7 – 4.5 gal/min with 363 psi max pressure.

  • Green stator: larger flow with max particle size 5/32", while Purple stator max particle size is 1/8".

What this means in practice:

  • Purple stator = slower output, more pressure, better for denser, stickier materials, longer hose runs within limits, and fine work like tuckpointing.

  • Green stator = higher flow, lower pressure, better for volume placement where pressure demands are lower.

For tuckpointing or detailed repair, the purple rotor/stator combination is recommended because it can push material through small nozzles and tight joints without over‑delivering and making a mess.

Typical Applications for the Imer Purple Stator

The Imer Purple Stator is particularly suited to specialty and precision pumping applications, including:

  • Tuckpointing and repointing on brick and stone masonry, where controlled, low‑flow delivery is critical.

  • Repair mortars and restoration products, especially those with fine aggregates.

  • Thin plasters, injection mortars, and detail work where over‑pumping would cause waste or poor finish.

  • Jobs requiring higher discharge pressure through longer hoses or smaller diameter hoses, within the pump’s rated limits.

IMER’s training video on adjusting rotor/stator assemblies uses the purple rotor/stator on a Small 50 pump as the example, specifically calling it “a low‑flow rotor/stator used in the tuckpointing application on the Imer Small 50 pump.”

Rotor/Stator System: How the Purple Stator Works

IMER’s rotor/stator pumps use a progressive cavity design:

  • The stator (Purple Stator 1107084) is a molded elastomer liner inside a steel tube.

  • The rotor (Purple Rotor D5‑2.5, 1107085) is a helical steel screw that turns inside the stator.

  • As the rotor turns, cavities form and progress along the stator, moving material smoothly and nearly pulse‑free.

IMER explains that these pumps deliver:

  • “Smooth, pulse‑free flow for a wide range of materials… where control, finish quality, and reach matter.”

The purple stator config modifies the geometry to produce smaller cavities and tighter clearances, hence lower volume per revolution but higher pressure capacity.

Wear and Adjustment of the Purple Stator

The stator is a wear part. IMER’s rotor/stator adjustment video notes:

  • “The rotor/stator is a wear item. The stator itself has a rubber inside that the rotor pushes material against and over time it will wear.”

Symptoms and adjustment:

  • If you notice a loss of flow, you should tighten the rotor/stator assembly, using the 19 mm bolts and nuts.

  • Tighten slowly and evenly, “one tighten for each one and then start over again until you notice an increase of flow.”

  • Do not over‑tighten; if fully tightened and flow is still minimal, “it’s time for a new stator and perhaps a new rotor as well.”

These principles apply to the purple stator just as they do to other IMER stators, but the purple setup is more sensitive because it is used with higher pressure and finer materials.

Part Numbers and Kits: Purple Stator and Rotor

For a complete purple rotor/stator system on IMER pumps, you typically need both:

  • Purple Stator D5‑2.5 – 1107084: the stator only.

  • Purple Rotor D5‑2.5 – 1107085: the rotor only, “purple, for Small 50, Koine 4, Koine 35; goes with purple stator part # 1107084.”

Some dealers sell them individually, others bundle them in D‑series rotor/stator kits for Mighty Small 50 and Koine pumps. Matching rotor and stator is important to maintain the designed flow and pressure characteristics.

Pricing and Availability

The Imer Purple Stator 1107084 is widely available through IMER distributors:

  • Blades Direct lists “Imer Purple Stator – SKU: 1107084 – Regular price $209.00.”

  • Master Wholesale lists “Imer Purple Stator D5‑2.5 – 1107084” with typical 2–3 day delivery.

  • Vovlift offers “IMER 1107084 | 2.5 Purple Stator D5” with 60‑day returns. 

  • ConSpec and RenoItems reference the purple stator in Small 50 setups, sometimes showing sale pricing (e.g., down from $209.00 to around $52.25 in promotional bundles).

Because the purple stator is a specialty configuration used heavily in repair and tuckpointing work, maintaining at least one spare in inventory is common practice for contractors who rely on IMER pumps.

When to Choose the Purple Stator over Other Options

Choose the Imer Purple Stator when:

  • You need fine control and higher pressure for tuckpointing or narrow‑joint work.

  • Your material is dense but with fine aggregates (max particle size about 1/8").

  • You’re using a Mighty Small 50, Koine 35, or Koine 4 in applications where standard green stators (higher flow) are too aggressive or cannot maintain pressure.

Stick with a green or other higher‑flow stator when:

  • You’re placing higher volumes of plaster, stucco, or fireproofing over large surfaces and pressure demand is moderate.

Matching the stator to the job is critical for maximizing pump efficiency and finish quality.
