Vortab flow conditioners enhancing pump efficiency and service life

The efficiency and service life of pumps can be greatly extended by
following the manufacturer’s installation recommendation for pipe straight run
entering the pump. However, cramped pump houses or restricted pipe runs can make
this impractical and costly.

AMS Instrumentation and Calibration presents flow conditioners from The
Vortab Company, designed to overcome this challenge by delivering a uniform,
swirl-free flow profile to the pump inlet in as little as six pipe diameters.

Upstream flow disturbers such as elbows, expanders or reducers, and
valves often produce non-uniform, non-repeatable and swirling fluid flow in the
pump that can lead to pump cavitation and other issues causing premature wear.
The result is extra maintenance, expensive repairs and/or premature
replacement, which can take equipment offline. Vortab products provide
effective process conditioning to protect pumps.

The Vortab Company’s product line of process flow conditioners, with
their exclusive flow profile and anti-swirl tab design, corrects flow
disturbances to mimic adequate pipe straight run and produces a highly
repeatable, symmetrical flow profile. Vortab flow conditioners are proven to be
the industry’s lowest pressure drop flow conditioning technology, which reduces
energy costs and minimises process design considerations. Their use also
eliminates the extra pipe cost and technician labour for additional lengths of
pipe straight run and/or moving equipment around to accommodate new pumps.

Swirl reduction and velocity profile correction occur naturally in long
lengths of straight pipe due to diffusion, friction and turbulent mixing. The
Vortab flow conditioner’s anti-swirl and inclined vortex generating profile
correction tabs, projecting from the inner pipe surface, generate vortices that
accelerate these natural pipe effects to create a uniform, non-swirling,
symmetrical flow profile in a much shorter section of pipe.

The simple, flexible designs of the Vortab elbow (Model VEL) and the
Vortab insertion sleeve (Model VIS) configurations provide a cost-effective,
easy-to-install solution that supports proper pump installation. They can be
made from carbon steel, 316L stainless steel or Hastelloy C-276 and in almost
any pipe size. A variety of process connections are also available including ANSI
flanges, male NPT threads, butt welded preps or retaining wafers.

The Vortab range of flow conditioners is available from AMS
Instrumentation and Calibration in a range of sizes and connections.
