The screw pair is a pumping device (used in plastering stations, mortar pumps, putty stations), it provides the movement of the solution to the place of use. 

The resource of the screw pair depends on the following factors: the number of revolutions, the type and quality of the solution, the height and distance of the feed, the diameter of the sleeve. The screw pump works with gypsum, cement-sand, cement-lime, adhesive, self-leveling and putty compounds. Depending on the tasks and material properties, different screw pairs are installed.

The pumping unit is easy to maintain and does not require highly qualified service personnel, and frequent and expensive maintenance during operation.

The ROTORS TECH D6-3 stator and rotor are universal and can be used at plastering stations 220 / 380V for all types of mixtures: cement-sand and gypsum plaster.

In addition to the rotor variants presented below, the company is able to manufacture MP10, MP13 and other types of rotors according to individual customer requirements.

Operating instructions for "ROTORS TECH" auger pairs

  1. Wipe the preservative oil off the rotor with a cloth before screwing the rotor into the stator. Do not screw in and leave the rotor lubricated with oil in the stator. The oil softens (dissolves) the stator rubber and the stator fails.

  2. Do not run the station "dry", without water, in order to avoid burning and destruction of the stator rubber, and breaking off the rotor head.

  3. Before starting the station, check that there is no play in the agitator drive coupling. The agitator play creates a beating on the rotor head and breaks it off.

  4. Before assembling the rotor into the stator, coat their surfaces with silicone grease (spray).

  5. Do not use liquid soap. It does not create a sliding film on the surface of the rubbing parts, which leads to the stator biting the rotor, and as a result, the rolling of the pins, the breakdown of the mixer, and the chipping off of the rotor head.

  6. Remove the rotor from the stator for a period of long station shutdown (more than 2 days)

  7. Before starting the station on the already working steam, it is necessary to turn the rotor in the stator with a knob to break their seizure.

  8. Handle the rotor with care. Do not drop or throw it. The rotor is made of cast iron, which gives it high abrasion resistance to mortars. But at the same time, this property makes it fragile to blow.


Instructions for mounting the "ROTORS TECH" rotor into the stator:

  1. Fix the stator, for example in a vise or in the mixing chamber flange of the plastering station.

  2. Prepare a lever that will fully fit into the rotor groove along its entire length (if it is not along the entire length of the groove, the rotor head may break).

  3. Liberally lubricate the rotor and the inner cavity of the stator with silicone grease (spray). Do not use liquid soap and petroleum products for lubrication. They lead to swelling of the rubber part of the screw pair and, as a result, lead to jamming of the screw pair.

  4. Insert the rotor into the stator recess, then press the rotor into the stator and screw it in until the rotor on the opposite side is flush with the stator rubber.
