IMER's Mighty Small 50 is a portable progressive cavity pump built to pump and spray grout, mortar, stucco and fireproofing on work ranging from bridge deck repair to high-rise fireproofing and filling blocks with grout. It is sized to be moved around a site rather than parked, and the hopper sits at 25.5 inches so a compatible mixer such as a Spin 15 or Mix 120 feeds it continuously from directly overhead.

Both configurations are the same pump body, stainless steel hopper and D8-1.5 rotor and stator, run through IMER's inverter control, which changes pump speed by modulating frequency rather than swapping gears, and both carry an electric remote control on 53 feet of cable so the pump is worked from the placement point instead of from the machine. What the buyer is choosing is output and the range of work it will reach. The Evo runs 1.75 HP on ordinary 120V service and moves up to 60 fifty-pound bags an hour, which is the configuration for a site with no 240V to hand. The Plus runs 3 HP on 240V single-phase for roughly double that throughput, and it is the only one of the two that accepts IMER's high-pressure airless kit, so spraying air and vapor barriers, heavy paints and coatings is work the Evo cannot do whatever accessories are added to it. If that work is in prospect, the 240V requirement is what it costs.

Common Applications

  • Pumping grout and self-leveling underlayments
  • Spraying fireproofing, repair mortar, or stucco base coat
  • Tuck-pointing and controlled-pressure grout injection
  • Spraying AVBs, heavy paints and coatings, on the Plus with its optional airless kit

Selection Notes

  • The Evo needs only 120V service; the Plus requires 240V single-phase
  • Only the Plus accepts the optional high-pressure airless spray kit for AVBs and heavy paints/coatings, which is a capability difference rather than a voltage change
  • A compatible mixer (e.g. Spin 15 or Mix 120) can sit directly over the 25.5 in hopper for continuous feed
  • An optional compressor and vibrating grid drop into either configuration
