progressive cavity pump
1.Stator rubber is prepared on the basis of the chemical features of oil and tested on rubber swelling,in order to guarantee adaptability of stator to the working enviroment.
2.The special intersecting surface of stator can reduce adsorption torque when starting adn avoid the damage of pump oil bar.
3.Due to the special surface of rotor which undergoes special technological process,rotor gets more resistant to abrasion.
4.The rotor with access hole of diameter 20mm is used with washing well valve in order to implement thermal wax removal with low pressure and high delivery capacity,what can increase the sevice life of pump.
