Vertiflo Pump
This sump pump ensures
unrestricted flow
The Series 900 Industrial Vertical Immersion
Vortex Sump Pump (photo),
available for service in industrial and
municipal applications, provides an
unrestricted flow since the impeller is
not in contact with the solids being
pumped. Applications include chemical
slurries, fragile food-processing
solids, pulp-and-paper solids, petroleum
products, wastewater, sewage
and more. It is designed for long life
in severe services with heads to 170
ft., temperatures to 350°F, pit depths
to 26 ft deep, and flows to 1,600 gal/
min. Several materials of construction
are available. - Vertiflo Pump

This pump has a dry-running,
frictionless sealing system
The TCC DryRun submerged pump
has a bearing and sealing unit that
has no contact with the pumping
medium. The axial bearing preload
ensures sufficient minimum load without
any hydraulic force when the impeller
is not immersed in liquid, says
the company. The pump's modular
design provides operating flexibility;
for instance, the basic version ensures
an immersion depth of up to 2.40 m;
by installing intermediate bearings, immersion
depths of up to 5.50 m can
be achieved. The pump has relatively
low installation and maintenance costs
and a maintenance interval of 3-5
years. - Paul Bungartz GmbH & Co.

Get realtime insight on pump
flow, head and efficiency
The PumpSmart PS220 (photo)
provides intelligent
process insight and diagnostic data
without the need for external sensors.
This helps operators to optimize
pump control strategies and
reduce system design and operating
costs, says the company. - ITT Pro

Cordless, self-priming pump is
designed for water removal
The M18 Transfer Pump (photo) is
both cordless and self-priming. It
pumps up to 480 gal/h and its flexible
impeller helps to produce a powerful
pressure differential that can produce
18 ft of lift and 75 ft of head, says the
company. Its viewing window helps
operators avoid blockages. Its cordless
design eliminates the need for
a.c. power and cords, while its selfpriming
design helps to eliminate
steps during setup. Equipped with
Redlink Intelligence, the Transfer
Pump switches off when the application
is complete and the tool begins
running dry, protecting the motor. -

pump control and protection for single
and multiple pumps. It helps to
improve pump reliability and safety
by protecting against upset conditions,
such as dry run, minimum
flow and cavitation. It uses so-called
Advanced Sensorless algorithms
to critical performance parameters
such as flow, head and efficiency
in realtime, and provides valuable

This pump combines gentle
handling and low energy use
The SRU rotary-lobe pump (photo)
is designed to provide smooth,
low-shear pumping and good energy
efficiency. Its design minimizes
the risk of contamination, making
it well-suited for applications in the
dairy, food, beverage, personal care,
biotechnology and pharmaceutical
industries that require hygienic,
low-shear and low-pulse operation.
The pump has clean-in-place and
sterilize-in-place capablilities to support
operators' rigorous validation
requirements, says the company. -

line of Husky 1050 natural gasoperated,
1-in. (25-mm) doublediaphragm
pumps (photo, p. 23)
operate safely on natural gas or
compressed air. They are designed
