Imer Small 50 Controlled Pressure Grout Kit is a complete OEM injection package that transforms the IMER Mighty Small 50 pump into a controlled‑pressure grout injection system for filling blocks, voids, cavities, and joints with consistent, regulated pressure. Built around the Small 50’s eccentric screw pump, this kit adds a pressure limiter, injection control relay, specialized gun, and hoses to ensure grout flows steadily into the void being filled without over‑pressurizing the structure.

What is the Imer Small 50 Controlled Pressure Grout Kit?

The Imer Small 50 Controlled Pressure Grout Kit (also sold as the Imer Grout Injection Kit, part #1107006) is an optional accessory set designed specifically for use with the IMER Mighty Small 50 pumping and spraying machine. It is described as a kit “that allows controlled pressure grouting with a Mighty Small 50 Pump,” and as the “Small 50 Optional Controlled Pressure Grout Kit.”

IMER and distributors position this kit for applications where you need to inject grout under controlled pressure rather than simply pump it freely, such as block fill, door jamb grouting, void filling, and some structural repair work.

What’s Included in the Controlled Pressure Grout Kit (1107006)

Multiple dealers list the same kit contents for the Imer Small 50 Controlled Pressure Grout / Grout Injection Kit:

According to Contractors Direct, Master Wholesale, StoneTooling, and Prime Industrial, the kit includes:

  • Pressure limiter / injection control system

    • “Limiter” plus an injection control relay switch that maintains consistent pressure so the material works its way through the void being filled.

    • Pressure meter and pressure gauge for monitoring injection pressure (noted in the IMER Grout Injection Kit description).

  • Hoses

    • 30 ft (approx. 9 m) of 1" (25 mm) diameter pump hose with cam couplings.

    • 15–16 ft (approx. 5 m) of 1" (25 mm) diameter pump hose with cam couplings.

    • Brass fitting M‑1" to F‑3/4" for connecting to various outlet points.

  • Application / injection gun

    • Application gun with 18 mm diameter nozzle.

    • Spray/injection gun with one deflector and 5/8" hose connector (as listed in StoneTooling’s IMER Grout Injection Kit description).

    • Gun clean‑out tool for maintaining the nozzle.

  • Cleaning kit

    • Nozzle file.

    • Hose cleaning sponges, including a 1" (25 mm) sponge ball for hose clean‑out.

This package gives you everything needed—limiters, pressure meter, hoses, gun, and cleaning tools—to configure the Small 50 as a controlled‑pressure grout injection pump.

How the Controlled Pressure System Works

The IMER Mighty Small 50 is an eccentric screw (rotor/stator) pump with inverter‑driven speed control and a material pressure gauge as standard equipment. The Controlled Pressure Grout Kit builds on this by adding:

  • Pressure meter unit and gauge

    • The kit includes a pressure meter unit and gauge that are installed on the material line, allowing real‑time monitoring of injection pressure.

  • Injection control relay switch

    • ContractorsDirect notes that the kit includes an “Injection control relay switch – maintains consistent pressure to ensure material works its way through the void being filled.”

    • This relay works with the Small 50’s control panel so the pump can automatically respond when a preset pressure is reached, preventing dangerous over‑pressurization.

  • Pressure limiter

    • A limiter device, referenced in the kit features, further helps regulate or cap maximum injection pressure.

In practice, the operator:

  1. Sets desired motor RPM (flow) using the Small 50’s rheostat.

  2. Uses the pressure gauge and limiter to remain within target injection pressure.

  3. Relies on the injection control relay to maintain steady pressure as voids fill and resistance changes.

This setup gives significantly more control than a simple open‑flow hose, which can easily over‑pressurize confined spaces and cause blowouts.

Integration with the Mighty Small 50 Pump

The IMER Mighty Small 50 (EVO or PLUS) is marketed as a multi‑purpose pump for grout, fireproofing, stucco, self‑leveling underlayment, and more. Key pump features include:

  • 110V or 220V single‑phase power options.

  • Material flow rate from about 1.7 up to 30–54 cu ft/hr, depending on model.

  • Max aggregate size up to 1/4".

  • Pumping distance up to 150 ft with grout, 200 ft with SLU.

  • Stainless steel hopper and D8 1.5 ECO rotor/stator.

The Controlled Pressure Grout Kit uses these pumping capabilities and adapts them for controlled‑pressure injection work by:

  • Adding 1" hoses of appropriate length and cam couplings.

  • Converting the outlet to an injection gun with 18 mm nozzle.

  • Introducing a pressure meter unit and limiter into the discharge line.

The Small 50’s inverter‑driven control panel and 5‑volt remote start/stop or compressor‑linked on/off (when spraying) already provide fine control over pump speed and behavior, and the grout kit’s relay integrates into this logic.

Typical Applications for the Small 50 Controlled Pressure Grout Kit

IMER and distributors call out several use cases for the Mighty Small 50 with controlled‑pressure injection:

  • Filling concrete masonry units (block fill) with grout.

  • Grouting metal door bucks and frames.

  • Pumping grout for self‑leveling materials into confined forms or cavities.

  • Void filling behind walls, under slabs, or around structural elements (within pumpable aggregate limits).

  • Tuck‑pointing and grouting between stones or bricks when configured with suitable gun and nozzle.

The controlled pressure aspect is critical whenever the grout is being injected into a confined or partially inaccessible space, where the operator must rely on pressure feedback rather than visual observation to know when the void is full.

Advantages of Controlled Pressure Grouting with the Small 50 Kit

Using the Imer Small 50 Controlled Pressure Grout Kit provides several advantages over basic grout pumping setups:

  1. Consistent injection pressure

    • The injection control relay switch and limiter maintain a set pressure, reducing the risk of blowouts, leakage, and structural damage.

  2. Improved quality and completeness of fill

    • Maintaining steady pressure helps grout move through the entire void or block cell network, improving bonding and structural integrity.

  3. Better feedback for the operator

    • The pressure meter and gauge give real‑time insight into what’s happening inside the structure, allowing more informed decisions about when to stop pumping.

  4. Cleaner, more controlled operation

    • An 18 mm injection nozzle and dedicated gun focus the grout where it is needed, aiding in precise placement and reducing spillage.

  5. Full OEM integration

    • As a factory‑engineered kit, the hoses, couplings, gun, and control relay are fully compatible with the Small 50, simplifying setup and maintenance.

Relationship to Other Small 50 Accessories

The grout kit is part of a larger ecosystem of IMER accessories for the Mighty Small 50:

  • Vibrating hopper (1107015) – keeps slow‑moving grout pumpable in the hopper, especially useful in tuck‑pointing and injection work.

  • Mortar, stucco, and fireproofing gun kit (1107005) – for heavy spray applications.

  • Light materials spray gun kit – for acrylic stucco and fine coatings.

  • Dual‑diaphragm compressor (1107546) – used for spray applications and to automatically start/stop the pump based on gun valve position.

The Small 50 Controlled Pressure Grout Kit specifically targets injection and pressure‑regulated grouting, and can be combined with these other accessories (e.g., vibrating hopper) for a complete, high‑control grout system.
