Sta­tors for eccen­tric screw pumps 

In the field of mate­ri­als han­dling, pro­gres­sive cav­i­ty pumps are suc­cess­ful­ly used for tasks that exceed the tech­ni­cal pos­si­bil­i­ties of pumps of con­ven­tion­al design. They have deci­sive­ly expand­ed the range of avail­able con­vey­ing sys­tems and are used for con­vey­ing high­ly vis­cous, abra­sive and cor­ro­sive media. The com­po­nents of the pro­gres­sive cav­i­ty pumps are the fixed sta­tor and the rotat­ing com­po­nent, the rotor. Rota­tion and the design of both com­po­nents cre­ate cham­bers through which the respec­tive media are trans­port­ed from the suc­tion to the dis­charge side of the pump.

Sta­tors con­sist of a steel jack­et lined with rub­ber. The com­po­si­tion of the rub­ber com­pound in the sta­tor depends on the require­ments of the pro­gres­sive cav­i­ty pumps and the medi­um to be pumped. 

In mate­ri­als han­dling tech­nol­o­gy, not only the abra­sion behav­iour but also the giv­en phys­i­cal, chem­i­cal and ther­mal medi­um prop­er­ties are impor­tant fac­tors that affect the com­po­si­tion of the mate­r­i­al in the sta­tor. The rub­ber mix­ture is there­fore com­posed in such a way that the mate­r­i­al wear of the sta­tor is kept as low as pos­si­ble. This increas­es the ser­vice life of your sta­tors and pre­vents cost­ly failures.

Our sta­tors for eccen­tric screw pumps have been used suc­cess­ful­ly for many years by well-known pump man­u­fac­tur­ers world­wide in var­i­ous fields of application: 

Wood pro­cess­ing and cel­lu­lose production

In paper mills, pulp, ground­wood, glue and paint must be con­veyed by means of sta­tors. These are media of crumbly con­sis­ten­cy, medi­um to high vis­cos­i­ty and chem­i­cal aggres­sive­ness. The sta­tors from Artemis guar­an­tee a long ser­vice life of the pro­gres­sive cav­i­ty pumps.

Food indus­try

In the food indus­try, eccen­tric screw pumps are replac­ing old, man­u­al process­es in the har­vest­ing of grapes, fruit and olives. They are also used in the dairy indus­try or in the con­fec­tionery indus­try to con­vey high­ly pasty mass­es such as choco­late, marzi­pan and dough. Our mate­ri­als and sta­tors used in the food indus­try meet the strict require­ments and qual­i­ty stan­dards of the food law thanks to our qual­i­ty controls.

 

Petro­le­um industry

Down­hole pumps in the field of crude oil pro­duc­tion offer a high degree of eco­nom­ic effi­cien­cy com­pared to tra­di­tion­al pump­ing equip­ment. Thanks to their easy instal­la­tion and main­te­nance, good con­trol­la­bil­i­ty and high effi­cien­cy under dif­fi­cult pump­ing con­di­tions, there has been a world­wide increase in the num­ber of pumps. To reduce long down­times and costs caused by pre­ma­ture fail­ures, we have devel­oped spe­cial abra­sion-resis­tant mate­ri­als for the sta­tors of the down­hole pumps. The geome­tries are fine-tuned to the expect­ed geo­log­i­cal tem­per­a­tures. We offer you com­plete sys­tems as well as a relin­ing ser­vice for worn stators.

 
 

Dos­ing technology

In the elec­tron­ics indus­try in par­tic­u­lar, ever small­er com­po­nents must be bond­ed or encap­su­lat­ed. One of the main tasks of sta­tors is there­fore to con­vey very small quan­ti­ties of var­i­ous media with a high degree of repeat accu­ra­cy with­out drip­ping. Due to the com­po­si­tion of the mate­ri­als specif­i­cal­ly adapt­ed to the media, our sta­tors achieve the high­est pos­si­ble chem­i­cal resistance!

Con­struc­tion industry

Espe­cial­ly in the con­struc­tion indus­try, the screw con­vey­ors have to con­vey extreme­ly abra­sive sub­stances. Artemis offers sta­tors of var­i­ous designs with a rub­ber or plas­tic cas­ing or slot­ted steel tube for reten­sion­ing to pre­vent wear and tear of the pro­gres­sive cav­i­ty pumps as far as pos­si­ble. We devel­op solu­tions for you so that we achieve an opti­mum ser­vice life for your pro­gres­sive cav­i­ty pump!

Chem­i­cal industry

In the chem­i­cal indus­try, the resis­tance of the stator’s elas­tomer must meet the high­est demands. Media to be pumped can be all kinds of sub­stances, such as fil­ter cake, which has hard­ly any liq­uid prop­er­ties, sludge and many oth­er chem­i­cal sub­stances. Our sales teams and lab­o­ra­to­ry tech­ni­cians will sup­port you in select­ing the appro­pri­ate com­pounds for your appli­ca­tion. Our resis­tance list has proven to be a use­ful tool in this context.

 
 

Excel­lent mix­ing tech­nol­o­gy and high­est quality 

Artemis sup­plies a wide stan­dard range of com­pounds that are resis­tant to a vari­ety of media. We have our own com­pound devel­op­ment and pro­duc­tion facil­i­ties, enabling us to respond opti­mal­ly and flex­i­bly to cus­tomer require­ments. 

Using the lat­est 3D tech­nol­o­gy, our appli­ca­tion engi­neers design per­fect­ly matched sta­tor and rotor geome­tries with sub­se­quent sim­u­la­tion of the oper­at­ing behav­iour. 

Com­pli­ance with func­tion­al­ly tight dimen­sion­al tol­er­ances of the man­u­fac­tured sta­tors is essen­tial for us. To ensure this, we test the com­po­si­tion and qual­i­ty of our self-pro­duced or pur­chased mix­tures as well as prod­ucts in our in-house test lab­o­ra­to­ries. Our exten­sive machine park enables us to pro­duce small, medi­um and large series of almost any sta­tor size at opti­mum part costs for you.

Spi­ral stators 

Artemis also man­u­fac­tures sta­tors with uni­form rub­ber wall thick­ness under the brand names TWISTER® for plas­ter mor­tar pumps and SPIRA® for the oil sec­tor. The prop­er­ties of the coiled sta­tors con­sid­er­ably extend the range of appli­ca­tions for the pro­gres­sive cav­i­ty pump!
