Imer Small 50 Multipurpose Pumping, Spraying Machines

Use with all types of finish coatings. Quickly and easily apply materials such as plasters, mortars, stucco (cement and synthetic based) fire proofing, sound proofing and paint. Pump grout to fill blocks, metal door bucks, self leveling materials, epoxy, almost any material with aggregate no bigger than 1/4"

The pump is controlled by the operator either with the 5 volt remote start/stop or, when used with the optional diaphragm compressor, is controlled with the open and closing of the valve at the gun. A rheostat controls the motor RPM which means that you have total control of the flow to match with the material being applied. All of the operation is controlled by the panel which can detect the wrong voltage and shut down as a safety. The unit will sense a jamb and cut the power to the pump. Thermal overloads are in place on the 100% duty cycle motor. This means that the motor can run all day, every day. The control panel will sense an overload before the thermal protection on the motor. This is just the level of how safe, secure and sophisticated this machine is.

The optional IM250 Small 50 Compressor is needed when used for spraying applications. The oil-less, continuous flow, low PSI high CFM compressor is the lungs of the unit. The pumping action is all on the operator. With the air valve closed the compressor senses back pressure and turns off the compressor and the pump motor. When the valve is re-opened the compressor and the pump kick on again to start where you left off.

There are 2 different nozzles for spraying. One is for heavy materials that needs to be built up such as fire proofing materials and mortars. The other nozzle is used for spraying of thinner coats such as acrylic stucco and coatings. This nozzle comes with different orifice sizes and when used without the compressor, makes a great tool for pointing, filling in cracks and joints in between stone walls.

Note: The pump is sold separately from the application kits as the kit chosen depends upon the work needed to be performed.

Questions & Answers
12 questions

What is the max hose length I can use?

Depending on the application, self leveling underlayment can travel long distance over 150 ft. horizontally, while other upward pumping like mortar applications would be limited to 60 ft. vertically. Consider the hardening time of the product used, fast setting materials would require shorter hose length. Different rotor and stator can increase distance but deliver lower flow rate.

Can I operate the pump remotely?

Yes the included wired control remote when plugged in will override the start and stop, when the pump is on. Reverse and stop will still function from panel. When using the compressor and a gun kit, the wire remote is not needed, opening the gun air valve will trigger and start the pressure switch on the compressor. Pump needs to be on forward mode, a flashing number and display "stop" indicating that the pump is on standy.

How do I adjust the stator?

The small 50 as an adjustable stator, as abrasive material containing sand go thru will wear the stator over time. The adjustable bolts on the stator will squeeze a tighten the rubber inside the stator to maintain proper pressure.

Can the small 50 pump continuously ?

Yes, the small 50 uses a 100% duty motor that can truly run continuously 24/7. The inverted features a high temp shut down if ever needed.

How long will a rotor and stator last?

It s material dependent, when using a silky smooth material such as straight Portland cement very little wear will occur but If using a product that is very abrasive such as Euchoshot or with silica fume then maybe just a few hundred bags. Routine maintenance should be performed at the end of each work day to ensure that the rotor & stator are well calibrated. Tip: To calibrate the stator, fill the hopper with water, set the speed to 50Hz, attach the material hose to the end of the pressure gauge. Kink the hose as you would a water hose and turn on the pump. The pressure gauge should read 120 to 140 PSI. if not then tighten evenly the 3 adjustable bolts on stator. If the pressure can t be reach then it s time to replace rotor and stator.
