The SPR 75 plastering machine with a screw pump is designed primarily for pumping, conveying and spraying of plaster mixtures with a particle size of up to 6 mm. The device output can be adjusted with its variable-speed drive or by using pumps of different capacity. To spray plaster, the SPR 75 conveying pump must have compressed air at 400-800 L/min (3-6 bar). Using different spray guns and pistols, plaster can be applied for smoothing walls or retouching facades. Differently structured sprayed plaster surfaces can be made as well.
The SPR 75 plastering tool can be also used to pump floor-levelling mixtures. Due to the simple construction of the conveying pump, its casing made from galvanised steel and the large rubber wheels the device SPR 75 is very reliable and can be conveniently moved around during construction work.
