SPIRA® stators for drill motors

Spira® stators offer many advantages over conventional stators. In particular, the higher torque for the same stator length, the uniform swelling in aggressive drilling fluid media and the uniform thermal expansion ensure significantly higher efficiency and longer durability. 

Spira® stators therefore drill to the required depth even in difficult applications without having to be replaced in between, thus saving a lot of time and money. The availability of different elastomers such as NBR, NBR-HR, HNBR and FKM for our stators offers optimal adaptation possibilities for your applications.
