Smart pump saves
up to 30% in energy costs
The new xLC-select stator-adjustment
system (photo) is said to be
the world's first autonomous system
that automatically readjusts the
pump, and thus reduces energy
consumption. The xLC-select statoradjustment
system is an accessory
for progressing cavity pumps that,
based on algorithms, recognizes the
optimal efficiency of the pump completely
independently and adjusts
the stator optimally to it. Not only are
energy costs reduced by up to 30%,
but the CO2 footprint is also significantly
reduced, says the company.

A range of centrifugal pumps
for the CPI
This company offers a complete
range of centrifugal pumps for the
chemical process industries (CPI;
photo). The pumps are ISO-2858
and ISO-5199 certified and can be
offered in numerous configurations
in terms of materials and mechanical-sealing
configurations, virtually
covering the entire range of API 682
standards used in the chemical and
petrochemical industries. Pumps
can be supplied with different impeller
designs to get the maximum performance
considering the pumped
fluid characteristics. Magnetic drives
and special configurations are available
as options. A specific series
for hot-oil pumping up to 365°C is
ready for delivery. - Pompetravaini,

non-metallic AODD pumps
The new FTI Air FT025 1/4-in. air-operated,
double-diaphragm (AODD)
pump is manufactured from unfilled
polypropylene (PP), unfilled polyvinylidene
fluoride (PVDF) or conductive
carbon-filled PP and features Santoprene
or polytetrafluoroethylene
(PTFE)
diaphragms
for maximum
chemical compatibility. It offers 5.8
gal/min (22 L/min) maximum flow.

Pumping system manages
wastewater lift stations
The OverWatch direct inline pump
system (photo) lifts influent at the
point of entry, eliminating the wet
well. Effluent is contained, eliminating
odors and reducing maintenance.
The stainless-steel body is
designed to withstand the effects of
corrosion from harsh materials and
solutions, making OverWatch suitable
for the municipal, industrial and
commercial industries. The patented
system lifts effluent directly at the
point of entry, and a patented impeller/shredder
cuts fibrous materials
and other solids. Variable-speed
drives are available for continuous
modulated pumping directly
from
the effluent inlet to save energy. The
system averts dangerous gases,
such as H2S, and eliminates smells,
while preventing sand and grease
from accumulating. - Industrial

feature patented
alternatives, reducing maintenance
time and costs. The pump also features
a durable stainless-steel airline

works with many fluids, including
acids and bases, plating solutions,
wastewater and solvents. - Finish

based on the venturi principle
that generates the high amounts of
suction air and negative pressure
needed to transfer powders and
other bulk solids gently in dense
phase. The vacuum pumps operate
with compressed air, while eliminating
the rotating parts, motors, lubricants
and heat and ignition sources
common to electromechanical
pumps. A key part of removing any
potential
sources of ignition, the
Multijector vacuum pumps allow
explosion-proof, ATEX-certified conveying,
