The Imer Small 50 Optional Vibrating Screen is a dedicated accessory for the IMER Mighty Small 50 pump that screens loose, bulk materials before they enter the hopper, protecting the rotor and stator from rocks, stones, and debris larger than 5/16 inch. Designed specifically for bulk sand mixes and site‑mixed mortars, this vibrating screen keeps your Small 50 running smoothly, reduces clogs, and helps you pump and spray more reliably on demanding jobs.

What Is the Imer Small 50 Optional Vibrating Screen?

The Imer Small 50 Optional Vibrating Screen (part #1107548) is an add‑on screen and vibrator assembly that mounts on the Mighty Small 50’s hopper and plugs directly into the machine’s dedicated vibrator outlet. It is purpose‑built for the Small 50 EVO and Small 50 PLUS rotor/stator pumps and is listed in IMER’s official optional equipment for “vibrating screen for bulk sand mixes.” When activated, the unit vibrates the screen mesh so bulk material flows evenly while larger debris is trapped before it can damage the pump.

This makes the vibrating screen a critical accessory whenever you are using your own sand, site‑mixed mortar, or other loose materials instead of clean, bagged, pre‑blended products.

Key Features and Specifications

The Imer Small 50 Optional Vibrating Screen is engineered for jobsite durability and seamless integration with the Mighty Small 50 pump.

Core features include:

• Designed to screen loose materials that may contain rocks, stones, and debris larger than 5/16 inch.

• Vibrator and mesh combination still allow stones up to 1/4 inch in size to pass into the hopper.

• Required when using bulk or site‑mixed material; not needed if you use clean, bagged, pre‑blended mixes.

• Plugs directly into the Mighty Small 50’s dedicated outlet for the vibrator and is controlled from the main control panel with its own on/off switch.

• Part number: 1107548, commonly listed as “Imer Vibrating Screen for Mighty Small 50 Pump” or “Vibrating screen for bulk sand mixes.”

By combining a properly sized mesh with a matched vibrator motor, the unit gives you consistent screening performance without needing a separate screening machine or manual sifting.

How the Vibrating Screen Protects the Mighty Small 50

The Mighty Small 50 is a rotor/stator pump, which relies on a close‑tolerance screw and stator to move material; oversized particles can jam, score, or damage these components. The Imer Small 50 Optional Vibrating Screen is specifically designed to prevent that problem.

• Loose materials poured into the hopper first land on the vibrating screen mesh.

• Vibrations help finer material and correctly sized aggregate (up to about 1/4 inch) fall through the mesh into the hopper.

• Larger rocks, chunks, and debris (above roughly 5/16 inch) are retained on top of the screen, where they can be removed and discarded.

• This prevents oversized particles from entering the stator and screw, significantly reducing the risk of clogs, jams, and mechanical damage.

Because IMER rates the Mighty Small 50 line for a maximum aggregate size of about 1/4 inch, the vibrating screen plays an important role in keeping the pump within its design limits when using bulk materials.

When You Need the Imer Small 50 Optional Vibrating Screen

The vibrating screen is an optional accessory, but in many real‑world setups it is effectively required.

You need the Imer Small 50 Optional Vibrating Screen when:

• You use your own loose sand or site‑mixed mortar that may contain stones, clumps, or debris.

• You load material from bulk bags, stockpiles, or silos where screening is not guaranteed.

• You are pumping or spraying fireproofing, stucco, or mortar and want to protect the rotor/stator from accidental oversized particles.

You typically do not need the vibrating screen when:

• You are using bagged, pre‑blended material from reputable manufacturers that specify appropriate aggregate size and cleanliness.

• Your product data sheet clearly indicates that the mix complies with the pump’s max 1/4 inch aggregate requirement and is properly sieved.

In short, if there is any doubt about the cleanliness or gradation of your bulk material, the vibrating screen is recommended to avoid costly downtime and repairs.

Integration with the Mighty Small 50 Control Panel

The Imer Small 50 Optional Vibrating Screen was designed from the start to integrate cleanly with the Mighty Small 50 EVO and PLUS models.

• IMER’s official Small 50 documentation lists the vibrating screen for bulk sand mixes (part #1107548) as optional equipment controlled via the main control panel.

• The unit plugs into the dedicated vibrator outlet on the machine, so no additional wiring or external power is needed.

• An on/off switch on the control panel governs the screen, making it easy to start or stop vibration as needed during loading.

This integration means the screen behaves as part of the machine rather than a separate tool, simplifying setup and daily operation.

Components and Parts Behind the Vibrating Screen

The vibrating screen assembly for the Small 50 includes several key components, which are cataloged as sub‑assemblies in IMER’s parts listings.

Typical parts associated with the Small 50 vibrating screen include:

• Screen mesh frame that holds the actual screen where material is poured.

• Support structures for mounting and bracing the screen on the hopper.

• Motor vibrator unit that creates the vibration to move material across the screen.

• Shock absorbers and bushings to isolate vibration and extend component life.

• Electrical junctions, connectors, and plug to tie into the Small 50’s control panel and vibrator outlet.

These components are available as replacement parts, so you can maintain the vibrating screen over many years of use.

Benefits for Pumping and Spraying Performance

Using the Imer Small 50 Optional Vibrating Screen improves both productivity and reliability in real‑world pumping and spraying tasks.

Key benefits include:

• Reduced clogs and jams: By keeping oversized debris out of the stator and screw, you experience fewer interruptions to clear blockages.

• Longer rotor/stator life: Protecting the pump from rocks and hard particles helps minimize scoring, excessive wear, and premature failure of rotor and stator components.

• Smoother material flow: Uniformly screened material flows more consistently, supporting steady spray patterns and even coverage.

• Less manual screening: The vibrating action automates the screening process, saving labor compared to manually sifting or visually checking every batch.

For contractors working with fireproofing, stucco, mortar, grout, or restoration products, these advantages translate directly into less downtime and more productive work shifts.

Use Cases: Bulk Sand Mixes, Fireproofing, Stucco, and More

IMER specifically describes the vibrating screen as an accessory for “bulk sand mixes,” but its utility extends to many material types used with the Mighty Small 50.

Common use cases:

• Bulk sand‑based plaster and stucco mixes, especially when sand comes from a pile or truck.

• Fireproofing mixes where lightweight aggregates may clump or include oversize pieces.

• Site‑mixed mortars for masonry, tuckpointing, or stone work where material control is less precise.

• Grouts and plasters used in historic restoration and consolidation where the mix may include variable natural aggregates.

In each case, the screen helps you respect the Small 50’s stated maximum aggregate size (typically 1/4 inch), while still taking advantage of economical bulk materials.

Where the Imer Small 50 Optional Vibrating Screen Fits in the System

The vibrating screen is part of a broader ecosystem of accessories that allow the Mighty Small 50 to adapt to many jobs.

In IMER’s official Small 50 accessory lists, the vibrating screen sits alongside:

• Dual‑diaphragm IM250 compressor for spraying.

• Mortar, stucco, and fireproofing gun kits.

• Injection, leveling, grout, paint, and tuckpointing kits.

• Vibrating hopper for tuckpointing, overhead wands, and specialized hoses.

This positioning shows that IMER sees the vibrating screen as essential for certain material workflows, especially bulk sand mixes and heavy spraying applications.
