Vacuum pumps with hygienic
design for daily cleaning
The new DV 650 and DV 800 FP-r
washdown vacuum pumps (photo)
of the dry-running Dryvac series
have been introduced for vacuum
systems used in food and packaging
applications. The new screw vacuum
pumps require only a small footprint
and little installation space, and they
can be washed down inside and outside
in any installation position. Their
compact size and low noise level enable
uncomplicated, near-machine
installation in the immediate vicinity
of the production line. The advantage
for users: during daily cleaning
of the system, the DV 650/800 FP-r
pumps can be washed down with
the production equipment in one
process. This results in fewer system
downtimes, better cycle times, less
maintenance, a higher standard of
hygiene and higher filling and packaging
outputs, the company says. -

This electric double-diaphragm
pump is efficient
The Quantm pump (photo) features a
new electric-motor design that is said
to be up to eight times more efficient
than a standard pneumatic pump.
The pump is suitable for nearly any
fluid-transfer application and offers a
wide range of materials of construction
to support multiple industrial and
hygienic applications. The electric
pump is designed for use as a dropin
replacement for current pneumatic
pumps or for greenfield construction.
With built-in controls and no gearbox,
the pump also fits seamlessly
into most fluid-transfer applications.

Multistage, double casing
pumps for CCUS applications
Introduced in February, the BB5 pump
(photo) is fully compliant with API 610,
and will be used in carbon capture,
utilization and storage (CCUS) processes.
The BB5 pump has the option
to swap out individual stages in
the future, giving users the flexibility to
adjust their hydraulics. This provides
each pump with a wide-ranging, advanced
hydraulic coverage that engineers
tailor to meet the needs for each
application. Flowrates in excess of
1,000 m3/h can be achieved, with
heads greater than 3,660 m. The
pumps can operate at temperatures
up to 450°C and have a standard
working pressure of 15,000 kPag. The
pumps are available in API 610 table
H.1 materials, and flange sealing options
are available to match users'
requirements. - CPC Pumps International

These new plunger pumps
have a compact design
This company has added two new
compact plunger pumps to its portfolio,
the P3-85 with a maximum power
of 700 kW, and the P5-85 (photo),
with a maximum power of 1,200 kW.
The pumps feature an integrated
gearbox and a short design, with a
stroke of 100 mm and a rod force of
280 kN. The Px-85 series enables an
increased performance compared to
long-stroke designs. The short design,
the elimination of external gears
and the optimization of performance
makes it possible to replace several
pumps with one in some cases.
Flowrates of up to 2,100 L/min for
the P3-85, and 3,500 L/min for the
P5-85. - Uraca GmbH & Co. KG,

Wastewater impeller combines
efficiency and reliability
In a further expansion of its range of
pumps suitable for handling untreated
wastewater, this company has developed
a new radial multi-vane impeller
with an open design. The D-max impeller
(photo) handles fluids containing
solid substances, long fibers and
coarse solids, as well as entrapped
gas or air. It is therefore very suitable
for handling untreated waste water,
combined sewage, recirculated and
heating sludge, as well as activated,
raw and digested sludge with a solids
content of up to 8%. This impeller type
is also suitable for transporting fluids
with a high viscosity. At approximately
84%, the new impeller's best effiCHEMICAL
