Product Description

Pump connector eliminates turbulent flow at pump intake

How it works

The Suction Diffuser Flex Technology consists of a specially designed set of stationary vanes placed upstream of an elbow. The Suction Diffuser Flex imparts to the fluid a gyroscopic motion, which counteracts the elbow induced motion, enabling the fluid to negotiate the turn uniformly and exit with a flat velocity profile.

The Suction Diffuser Flex offers:

Guaranteed measurable improved pump performance
Reduced pump vibration and wear, maximizing pump operating life and helping reduce pump maintenance
Increased pump efficiency
Increased flow rate

Suction Diffuser vs. the Energy efficient SUCTION DIFFUSER FLEX

Pressure drop is the resistance to flow as a liquid moves thru a pipe. It is caused by the viscous shear within the liquid and turbulence along pipe walls. The more the pressure drop the more energy is consumed to overcome it. The Suction Diffuser Flex is far more efficient compared to a suction diffuser!

Product Highlights
