Special features:

The rigid stator,elastic rotor screw pump is a new-type screw pump,breaking the original design ideas,changes the stator the inside liner is rubber into full metal stator and changes the steel rotor into the made from alloy steel and same wall-thickness rubber.So if the rubber rotor is worn,resulting in lower efficiency,can be replaced directly, and the stator does not need to be pulled out, saving production costs.The same wall-thickness rotor makes the pump initial torque is small,single-level pressure capacity significantly higher than thai of the common screw pump,in the same well depth,making series of pumps to reduce and shorten in length;the rotor is made of high temperature resistant rubber,meeting the needs of heavy crude oil thermal recovery.

The advantages: high-pressure,low-torque,high-temperature resistant,long life,lower power requirements,larger displacement.
