SPIRA® sta­tors for drill motors

In addi­tion to con­ven­tion­al sta­tors, Artemis also pro­duces sta­tors with uni­form rub­ber wall thick­ness under the brand name Spi­ra®. These sta­tors used in drilling motors are main­ly used in the oil sec­tor, but also for geot­her­mal or mine drilling.

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.

Advan­tages of SPIRA® Sta­tors

  • High­er effi­cien­cy due to increased motor dif­fer­en­tial pres­sure

  • Bet­ter heat dis­si­pa­tion

  • High per­for­mance, high tem­per­a­ture resis­tant NBR and HNBR rub­ber com­pounds

  • Increased dura­bil­i­ty / less stum­bling / deep drilling

  • Suit­able for motors with low speed and high torque

  • High­er torque at the same length com­pared to con­ven­tion­al sta­tors

  • Short­er pow­er sec­tions at the same torque com­pared to con­ven­tion­al pow­er sec­tions

  • Reduced swelling and sta­tor pro­file defor­ma­tion due to aggres­sive drilling flu­ids

  • Uni­form swelling around the sta­tor con­tour

  • Uni­form ther­mal expan­sion around the sta­tor con­tour

  • Min­i­mal sta­tor pro­file dis­tor­tion due to ther­mal expan­sion

  • Excel­lent ther­mal con­duc­tiv­i­ty through a thin, uni­form rub­ber lay­er and con­tour­ing

  • Steel pipe

  • Min­i­mum inter­nal heat­ing, no hys­tere­sis

  • High-pre­ci­sion, con­sis­tent­ly high-qual­i­ty sta­tors and rotors “Made in Ger­many
