IMER Silent 300 Pumping / Spraying / Mixing Machine

Due to size, this item can only be shipped to a Commercial Address.

The Silent 300 Prestige is a diesel-powered multi-purpose pump and spray machine with a built-in 6.3 cubic foot hydraulic mixer and onboard compressor for spraying. The military spec control panel integrates all these functions in one location to allow operators to quickly and easily learn to operate the pump. Known for its versatility, the Prestige is designed to use different rotor/stator combinations for pumping a variety of materials - including up to 3/8” aggregate. The heart of the Silent 300 is a Kohler / Lombardini 3 cylinder industrial duty diesel motor, this power plant is indestructible! The diesel motor powers an all hydraulic drive system, which also includes its own cyclone intercooler to keep the hydraulic fluid nice and cool. The combination of a powerful motor and a well designed hydraulic system means that the Silent 300 can mix, pump, and spray all at the same time.The hydro-electric controls are linked together by an on board computer which greatly simplifies operating the pump, and also provides a LED diagnostic read out panel to assist with any maintenance issues. The controls are all at your finger tips…operators get the hang of this pump real fast!

Choose from three different rotor/stator combinations; the 2L6 comes standard and is good for a wide variety of materials, use the IM25L when the aggregate content is high, and use the 60.12 when the job calls for high volumes of material. All these rotor/stator assemblies are adjustable to ensure a long life and consistent pumping action.Having these optional rotor/stators available makes the Silent 300 an even more versatile and complete pumping and spraying machine. The Silent 300 is the Boss Hog of all rotor/stator pumps…bar none!

The mixer on the Silent 300 produces plenty of blending and shear action, materials are mixed thoroughly and quickly. Our patented Folium II paddle design ensures that materials flow through the hopper, into the rotor/stator, and out the hose end at optimum speeds. This mixer is designed to keep up with the pumps fastest speed, another hopper full of material is always ready to go on time! This mixer is extremely reliable…it has to be because it’s feeding an expensive pump. To ensure there is much less paddle shaft bearing maintenance we went to the aerospace industry to source a Molybdenum/Teflon bushing. This system absolutely crushes even the best quality bearings in head to head torture tests. Grease these bushing once every week or two…not daily like metal bearings require!

Keeping operators safe is very important to Imer. The Silent 300 has interlock systems which will not allow the machine to operate if safety grates are not in place. Should a grate be out of position the diagnostic computer will post the appropriate warning on the control panel.
