PUMP TYPE SLM GV
SEALLESS WITH MAGNET DRIVE

Sealless multistage centrifugal
construction series SLM GV
As a member of Klaus Union’s successful
modular pump concept, the SLM GV further
extends our sealless application coverage.
The SLM GV pump is primarily used for applications
requiring high delivery heads.
Requirements have increased, become
more complex, and more specific in recent
years, particularly in the chemical and
petrochemical industry, where pumps handle
aggressive, toxic, and explosive liquids under
highest safety requirements. Klaus Union’s
new SLM GV pump series addresses today‘s
industry requirements – and offers new
efficient and demand-driven solutions.
Klaus Union satisfies these requirements
with over fifty years of experience in development,
construction, manufacturing, and in the
application of magnet drive pumps.
SLM GV – “V” stands for “variable” through
modular design. Features and benefits of the
modular “V-Concept” are:
E Few individual components –
multi-functional, individual application
E Greater safety over the
entire construction range
E Suitable for serial fabrication
at competitive prices
E Standard modules offer
many design variations
E Energy efficient systems
E Maximum flexibility and interchangeability
E Off-the-shelf availability of parts,
components and accessories
The construction series SLM GV covers the
complete performance range of multistage
centrifugal pumps. Pumps for high system
pressure applications are also available upon
request.

Safety and environmental protection
Quality assurance
A major component of our Company ethos is
to ensure the highest quality of our products.
Existing quality assurance procedures with our
suppliers are constantly monitored from order
placement, goods inward through to final
assembly. This quality assurance system, developed
on modern principles, complies with
the requirements of international regulations.
Klaus Union is a DIN EN ISO 9001 certified
Company.
