Imer Small 50 Optional Vibrating Hopper

Features

• Vibrating Hopper is used to keep slow moving grout pump-able
• use for controlled pressure grout injection with pressure regulator and tuck-pointing and grouting

The Imer Small 50 Optional Vibrating Hopper is a purpose‑built internal vibrator accessory designed to keep slow‑moving grout and mortar fully pumpable in the Mighty Small 50 pump and spraying machine, especially for tuckpointing, spacing, and controlled pressure grout injection. By gently vibrating the material inside the stainless steel hopper, it prevents bridging, helps dense mixes flow toward the rotor/stator, and improves consistency when using stiff or fine grouts.

What Is the Imer Small 50 Optional Vibrating Hopper?

The Imer Small 50 Vibrating Hopper (Part #1107015) is an internal hopper vibrator that mounts inside the hopper of the Small 50 EVO / PLUS pumping and spraying machine. IMER lists it as “internal vibrating hopper” and specifically recommends it for tuckpointing, spacing, and grout applications where the material tends to move slowly or hang up in the hopper.

ContractorsDirect and other dealers describe it as a vibrating hopper used “to keep slow moving grout pump‑able” and note that it is ideal when the Small 50 is used for controlled pressure grout injection and tuck pointing work. Instead of relying solely on gravity, the hopper walls vibrate, encouraging thick or sticky mixes to drop consistently into the pump intake.

Key Features and Specifications

While the vibrating hopper is an accessory rather than a stand‑alone machine, IMER and IMER Group documents provide essential details:

• Product type: Internal vibrating hopper for the Small 50 EVO / PLUS

• Part number: 1107015 (115V / 50–60 Hz version)

• Power supply: 115V, 50–60 Hz (a 230V version 1107016 is also listed for other markets)

• Compatible machine: IMER Small 50 EVO & PLUS (Mighty Small 50 series)

• Installation: Mounts as an internal vibrator on the hopper, working in conjunction with the hopper grid and bag splitter system.

• Recommended for:

  • Tuckpointing / spacing / grout

  • Slow‑moving, stiff, or fine grout mixes that need help to keep flowing

The vibrating hopper works alongside other optional accessories like the vibrating grid (for bulk sand mixes) and pipe hook to give the Small 50 a complete range of material‑handling options.

How the Vibrating Hopper Works on the Small 50

The Small 50 EVO / PLUS has a compact stainless steel hopper (about 1.74–1.75 cu ft) and a low 25.5" loading height. Inside the hopper, an internal vibrator can be mounted to gently shake the material as it feeds toward the pump intake.

According to IMER documentation:

• The internal vibrating hopper is installed in the hopper assembly (noted as item “1b) VIBRATOR” in the Small 50 manual’s component list).

• As material is added through the hopper grid and bag splitter, the vibrator breaks up bridging, reduces arching, and encourages consistent feed into the rotor/stator.

• The vibration can be used intermittently or continuously depending on how slow‑moving or stiff the material is.

This is especially important for tuckpointing or spacing grout, where mixes are often thicker and may not flow freely even in a stainless hopper.

When You Should Use the Imer Small 50 Vibrating Hopper

IMER explicitly recommends the internal vibrating hopper (1107015/1107016) for:

• Tuckpointing and spacing grout.

• Controlled pressure grout injection applications where material movement is slow.

Dealers expand on this by noting that it is used “to keep slow moving grout pump‑able” in controlled pressure work. You should consider the vibrating hopper when:

• You are pumping or injecting fine, stiff grouts that tend to bridge or hang on the hopper sides.

• You are tuckpointing or spacing mortar into joints and need steady flow without frequent agitation by hand.

• Your crew notices that the Small 50 pump is starved for material even though the hopper looks partially full.

For more free‑flowing premixed materials, SLU, or light plasters, the Small 50 often runs well without vibration, but the option is there when mixes become more difficult.

Difference Between Vibrating Hopper and Vibrating Grid

IMER offers both an internal vibrating hopper and a vibrating grid for the Small 50, and each serves a different purpose:

• Internal vibrating hopper (1107015 / 1107016):

  • Mounted inside the hopper.

  • Recommended for tuckpointing and grout.

  • Keeps slow‑moving material pumpable and prevents bridging.

• Vibrating grid (1107510 / 1107548):

  • A vibrating screen/grid placed over the hopper, powered separately.

  • Recommended for bulk sand mixes and on‑site mixed plasters and mortars.

  • Helps break down clumps, screen out oversized aggregate, and evenly feed more granular mixes.

In simple terms, the vibrating grid helps condition and screen bulk mixes as they enter the hopper, while the internal vibrating hopper keeps material already in the hopper moving toward the pump. Some contractors use both on the same machine when working with challenging sand‑rich site mixes.

Compatibility with Imer Small 50 EVO & PLUS

The Imer Small 50 Vibrating Hopper is part of the accessory ecosystem for the Mighty Small 50 EVO and Small 50 PLUS machines. These rotor/stator pumps are used for:

• Grouts (block fill, door jambs, rock wall finishing).

• Self‑leveling underlayment (SLU).

• Stucco, fireproofing, plasters, and coatings.

Optional equipment listed for the Small 50 includes:

• Dual diaphragm compressor.

• Mortar/stucco/fireproofing gun kits.

• Tuck point gun kit, controlled grout gun kit.

• Vibrating hopper for tuckpointing – Part #1107015.

• Vibrating screen for bulk sand mixes – Part #1107548.

• Pipe hook for block, form, and door jamb filling – Part #1107570.

This compatibility means you can configure the Small 50 for very different roles: high‑volume SLU pumping, fireproofing spray, or precise tuckpointing and grout injection with the vibrating hopper helping keep grout flowing.

Benefits of Using the Imer Small 50 Optional Vibrating Hopper

Adding the vibrating hopper to your Small 50 brings several practical benefits:

1. Improved material flow

   • Vibration reduces bridging and adhesion on hopper walls.

   • Ensures a more consistent feed into the rotor/stator, reducing pump “starving” and surging.

2. More reliable grout injection and tuckpointing

   • Controlled pressure grout injection and tuckpointing require steady flow.

   • The vibrating hopper supports consistent pressure and uniform joint filling, especially with fine or stiff mixes.

3. Less manual intervention

   • Without vibration, crew members may need to poke or shovel material toward the pump intake.

   • The vibrating hopper automates this, freeing labor and improving safety (less reaching into the hopper).

4. Better use of Small 50’s capacity

   • The Small 50 EVO / PLUS offers up to 30–54 cu ft/hr flow and long pumping distances.

   • Keeping material moving helps you take full advantage of that capacity instead of being limited by hopper flow issues.

5. Optimized for challenging mixes

   • Some grouts and tuckpoint mortars have high fines or polymer content and don’t flow easily.

   • The vibrating hopper is specifically recommended for these slow‑moving materials.

Typical Use Cases for the Vibrating Hopper

Based on IMER’s recommendations and dealer descriptions, typical jobs where the Imer Small 50 Vibrating Hopper shines include:

• Tuckpointing deteriorated masonry joints with premixed expanding or non‑shrink grout.

• Spacing and filling joints in block, stone, or brick walls where a constant feed of grout is needed.

• Controlled pressure grout injection for structural repairs, anchors, or void filling where flow consistency affects quality.

• Pumping fine, stiff grouts for rock wall finishing or door jamb grouting where the base mix tends to hang up in the hopper.

In all these cases, the vibrating hopper supports a more continuous and predictable pumping process.
