Spare parts：

In order to ensure the normal production and operation of customers, RoNice accumulates spare parts in stock,and also stores German well-known brand of the same quality of general accessories whose quality can be guaranteed.

Stator with equal wall thickness:

the rubber layer is thin and the rubber thickness is uniform, which is conducive to heat conduction. The helical shape of the stator shell increases the heat dissipation area, so that the heating of the stator with equal wall thickness is obviously less than that of the conventional stator and has a longer service life. The thin and uniform rubber wall thickness makes the stator rubber expand smaller and more uniform under the thermal effect, reduces the interference between the rotor and the stator rubber, makes the torque required for the start and operation of the pump smaller, but also reduces the power consumption of the motor, more energy saving and environmental protection, the process is feasible, but also has a high economic effect, compared with the conventional screw pump, fewer on-site accidents, small mechanical loss, improve pump efficiency, reduce costs.

Hollow rotor: 

weight reduction, and the conventional rotor axial torque is weakened, starting torque is reduced, reducer motor selection is small, customer use costs are greatly reduced, to achieve environmental protection and energy saving effect. In the process of operation, the friction of the rotor is weakened, the service life is increased, the vibration in the process of rapid start and high-speed operation is significantly reduced, the noise decibel is greatly reduced during the operation of the equipment, there will be no noise pollution.
