Conventional pump applications through unconventional technology
Revolutionary Innovative Functionality Simplicity
Contstant Volume Displacement High Power Density High Efficiency Flow of Fluid through pump

Constant Volume Displacement

System of matched gates rise and fall in a timed sequence to form a constant swept volume of fluid.

High Power Density

Outer housing rotates while shaft remains stationary. Allows for 10 fold increase in power density of pump.

High Efficiency

Positive displacement, ultra-low pulsation pump reduces costs through high efficiency and lower capital expenses.

Flow of Fluid through pump

Cam system is timed to allow for pressure balancing across gates before lifting or lowering them to minimize wear on gates.

A Revolution in Fluid Movement

The NOV CSV is a positive displacement pump. Regardless of the discharge pressure, the NOV CSV will always give the same delivered flow rate. With a 90% + mechanical efficiency, the NOV CSV is ideal for those focused on high energy efficiency. This high mechanical efficiency does not change with variation in either pressure or flow.
