Gentle product
treatment

Our centrifugal pumps are
renowned for their ability to
move products gently and
efficiently. The integrity of
your product is assured,
regardless whether you
choose a premium or
standard-duty model.
Advanced
hygienic design
With emphasis on features
such as optimized internal
geometry and profiled
o-rings, our centrifugal
pumps are suitable for
Cleaning In Place (CIP) and
offer exceptional levels of
hygiene. All have been
tested in accordance with
EHEDG requirements and
many are authorized to
carry the 3A symbol.
Advanced seal
design
Our LKH premium pumps
(models 5-60) and our
SolidC standard-duty pumps
share the same mechanical
shaft seal, which simplifies
maintenance and spare
parts inventory. Combined
with the quick and easy
front-loading design, this
reduces maintenance
costs, increases uptime
and reduces the cost of
ownership.
Easy seal
conversion
The external design of our
centrifugal pumps, as well
as the seal’s construction,
is designed to make seal
conversion as fast and as
simple as possible.
Our premium LKH pumps
can be converted from
single to flushed or doublemechanical
seals, while
our standard-duty SolidC
pumps can be converted
from single to flushed
shaft seals.
Computer-designed
impellers
Our centrifugal pump impellers
are computer-designed
and hydraulically balanced
for optimum performance.
Both the impellers and their
retaining screws (optional)
are smooth, which keeps
them from accumulating
product and makes
cleaning more effective.
Efficient
performance

Our centrifugal pumps
consume less power and
exhibit low noise levels.
In addition, they minimize
the risk of cavitation thanks
to low NPSH requirements.
 
           

Premium pumps
Quiet but rugged, Alfa Laval’s LKH series of centrifugal
pumps are the ultimate solution for gentle and
efficient product handling. Through a combination
of enlarged inlets and advanced impeller design,
they offer an unobstructed product flow and very
low NPSH requirements.
LKH pumps are designed for Cleaning In Place
(CIP). Polished models are USDA approved and
 
exceed 3A standards, so you can always be sure
of the greatest possible hygiene.
LKH pumps are available in capacities of up to
440 m3/h and pressures of up to 190 m (19 bar),
with different versions are available for specific
applications
 

   
LKHSP
Pumps in the LKHSP series are self-priming,
which means they can be used to pump products
containing air or gas. This makes them ideal as
return pumps in CIP systems, as well as for emptying
tanks. LKHSP pumps feature a tank, a non-return
valve (normally closed) on the inlet side, a tee and a
non-return valve (normally open) on the bypass line.

LKH-UltraPure
LKH-UltraPure pumps are high-purity models that
meet specifications for water-for-injection (WFI) and
other demanding applications. Authorized to carry
the 3A symbol, they are suitable for both CIP and
Sterilization In Place (SIP), as well as manual cleaning.
LKH-UltraPure pumps are also available with a 0.5
μm (150 grit) finish, 3.1 certification and a flushed
seal kit.
 completeline_pumps_en_img_3.jpg

 completeline_pumps_en_img_4.jpg  LKHP-High Pressure
Pumps in the LKHP-High Pressure series feature a
reinforced pump casing and backplate, as well as highpressure
internal seals and multiple heavy-duty studs.
This lets them handle inlet pressures as high as 40 bar
(600 PSI), making them ideal for nanofiltration and
reverse osmosis filtration. Their seals can be removed in
a matter of seconds, without removal of the back plate
 completeline_pumps_en_img_5_1.jpg  LKH-High Multistage
Designed to 3A standards and available in two-, threeor
four-stage models, LKH-Multistage pumps save space
and energy by replacing up to three booster pumps in a
line. Used primarily in high-pressure applications with low
capacity, they withstand system pressures up to 40 bar
(600 PSI) and deliver boost pressures up to 19 bar (275 Psi).
This makes them suitable for both reverse osmosis and
ultrafiltration..

Standard-duty pumps
 Alfa Laval’s standard-duty centrifugal pumps are
designed to offer high value for money. In addition
to gentle product handling and efficient operation,
they offer high reliability and possibilities for swift
and easy maintenance
The highlight of our standard-duty pumps is the
SolidC series, which combines a practical, costeffective
design with certain characteristics of our
premium LKH centrifugal pumps

 pu3.jpg
SolidC
The SolidC pump series is a reliable and cost-effective
solution for simple transport duties up to 85 m3/h.
It utilizes the same mechanical shaft seal found in our
LKH series, which is front-loaded and easily replaced
without removing the backplate. SolidC pumps are
available in four sizes and comply with 3A, CE and
EHEDG requirements.

GM Centrifugal Pump
The GM centrifugal pump series is a value-focused
alternative for industries in which acid-resistant steel is
required. GM pumps are specifically designed to handle
simple applications at low capacities, which makespu5.jpg
them a cost-effective solution.
 
Liquid ring pumps
Liquid ring pumps are an ideal solution when gases
are contained in the process medium. Because the
pumps are self-priming when the casing is half filled
with fluid, they are capable of pumping from a
suction line that is partly filled with air or other gases.
Alfa Laval’s liquid ring pumps are specially developed
for use in food, chemical and pharmaceutical
industries, where they are often used as return
pumps in Cleaning-In-Place (CIP) systems.
 

pu6.jpgMR-Liquid Ring
Through its simplicity of design, the MR series of
liquid ring pumps combines high efficiency with low
maintenance. The impeller is cast with straight,
radial vanes and is fixed onto a pump shaft within
a covered pump casing. A standard electric motor
is used to drive the MR pump head.
   

 
Rotary lobe pumps
  
Suitable for low, medium and high-viscosity
media, Alfa Laval rotary lobe pumps are the
fulfilment of more than 50 years of commitment
to rotary lobe pump technology. Their gentle
pumping action and reliable performance are
the result of continuous development, which is
based upon years of experience and carried out
at our advanced production and R&D facilities.
Our rotary lobe pump portfolio comprises three
ranges: SX, SRU and OptiLobe. Each of these is
robustly constructed and offers Alfa Laval’s high
