NTU Progressing Cavity Pumps

Produced with steel tube conformed with the same internal geometry as the stator (helical).Thus the elastomer has a uniform wall and produces even distribution of the elastomer.The main NTU pump feature is its lower operation and starting torque due to its lower swelling when exposed to temperature variations and chemically aggressive fluids.

Ideal for chemical fluids with high aggressivity

The difference of the NTU geometries

NTU-DT Geometry NTZ-ST GeometryNTZ-DT Geometry NTU-ST Geometry

The NTU pump features less rubber volume in relation to the NTZ pump (already on the market) which results in less swelling when used for pumping a chemically high-aggressive fluid.

Advantages

Higher run life in applications with critical conditions

Higher mechanical efficiency of the system

Lower starting torque

Lower swelling

Lower dimensional variation due the temperature and chemical attack

Shorter pump length

Higher pressure capacity per stage

Reduction on the failure register due the rod failure or disconnection

Easy installation and transport

Lower operational torque

Molded in tube with uniform wall guarantee

Easier to assembly in wells with deviations

Lower hystereses

Better heat dissipation
