Specifications

What our Experts Think

• Most versatile compact pump & spray system
  The IMER Mighty Small 50 (Ref. 1106344) is a portable progressive cavity pump designed for both pumping and spraying construction materials, making it a true multi-application job-site machine.
• Job-site power in a compact 110V unit
  Runs on 110V with a 1.75 HP motor, giving continuous-duty performance while still being light and portable enough for interior and high-rise work.
• Designed for a wide range of materials
  Handles grout, stucco, fireproofing, waterproofing, self-leveling underlayments, and repair mortars, making it a “system platform” rather than a single-purpose pump.
• Smooth continuous flow (no pulsing)
  Uses a D8 progressive cavity rotor/stator system to deliver consistent, controllable flow—critical for spraying and precise injection work.
• Strong performance for its size
  Achieves up to ~13 gallons per minute (depending on material and setup) with pumping distances up to 100–200 ft depending on application.
• System-based flexibility (big advantage)
  Can be upgraded with accessories like spray guns, compressors, overhead wands, grout kits, and different hoses, turning it into a full finishing system.
• Built for real job-site conditions
  Compact steel frame, stainless hopper, and inverter-driven control system allow reliable operation in tight indoor spaces and demanding environments.
• Expert insight
  This is not just a pump—it’s a modular material application platform. Its strength is adaptability: one machine can handle pumping, spraying, injection, and finishing tasks depending on attachments.

Q&A

Q1: What is the Imer Mighty Small 50 1106344 used for?
A: It is a compact professional pumping and spraying machine designed for grout, mortar, stucco, fireproofing, waterproofing, and self-leveling materials on construction and renovation sites.

Q2: What makes the Mighty Small 50 a “multi-purpose” system?
A: It can be configured with different accessories to pump, spray, or inject materials, making it suitable for grouting, coating, repair, and finishing applications in one machine.

Q3: What motor does the 1106344 model use?
A: It uses a 110V, 1.75 HP electric motor (EVO version) designed for continuous-duty professional operation on job sites.

Q4: What is the pumping capacity?
A: It delivers approximately 1.7 to 30 cu ft per hour material flow, depending on material type and speed settings.

Q5: What is the maximum hose distance?
A: It can pump materials up to about 100 ft with grout and up to 150–200 ft with self-leveling materials, depending on setup.

Q6: What materials can it handle?
A: It is designed for grout, mortar, stucco, fireproofing, waterproofing coatings, and self-leveling underlayments.

Q7: Is it suitable for job-site mobility?
A: Yes, it is compact, lightweight (~90 lbs), and easy to transport, making it ideal for tight job sites and interior work.

Q8: Does it support continuous operation?
A: Yes, it is built for 100% duty cycle continuous use, meaning it can run for extended periods without overheating under normal conditions

Maintenance Tips

• Flush system immediately after use: Run clean water through hopper, rotor/stator, hoses, and gun to prevent grout, stucco, or fireproofing material from hardening inside.
• Never allow material to dry inside pump: Progressive cavity (rotor/stator) damage is the most common failure—clean right after shutdown.
• Clean hopper daily: Stainless steel hopper resists corrosion, but leftover mix can still build up and affect feeding performance.
• Maintain rotor & stator condition: Inspect for wear or swelling; replace when pressure drops or flow becomes uneven.
• Check hose & gun kit regularly: Remove blockages and ensure fittings are tight to maintain stable pressure and flow.
• Inspect pressure gauge & control system: Ensure inverter control panel and diagnostics are working for overload or overheating warnings.
• Keep motor ventilation clean: Dust-free cooling vents prevent overheating during continuous-duty operation (1.75 HP motor).
• Avoid dry running: Running without material rapidly damages rotor/stator assembly.
• Lubricate seals lightly (if specified): Use only approved IMER-compatible lubricants—avoid heavy grease that attracts debris.
• Store dry & covered: Protect electrical components, frame, and hopper from moisture and jobsite contamination.
