SLM NV - “V” stands for “variable” through modular design. Features and benefits of the modular “V-Concept” are:

E Few Individual Components – Multifunctional, Individual Application

E Greater Safety over the entire Construction RangeE Suitable for Serial Fabrication at Competitive PricesE Standard Modules offer many Design VariationsE Energy Efficient SystemsE Maximum Flexibility and Inter- ChangeabilityE Off-the-Shelf Availability of Parts, Components and Accessories

The construction series SLM NV covers the complete performance range of single-stage centrifugal pumps. Pumps for high system pressure applications are available upon request.

SLM NV – More than just a Standard Pump

This pump, to DIN EN ISO 2858, is very much more than just a standard pump. It is the current further development in our well-proven series of sealless magnet drive centrifugal pumps. With the SLM NV, Klaus Union has developed a pump design to address today‘s industry requirements and to offer new efficient and demand-driven solutions. 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 satisfies these requirements with over fifty years of experience in development, construction, manufacturing and in the appli-cation of magnet drive pumps.

The Modular System

Klaus Union´s modular pump system is consisting of three different elements:The combination of these elements allows a large operating envelope with less different parts.By usage of over 100 different pump sizes and magnet drives, operation parameters up to 3.500 m3/h and 400 bar are realized. Interchangeability, stock size and services become easy subjects.

SLM NVS ... ZL

E Grease-Lubricated Anti-Friction Bearings with increased Bearing Spacing

E Non-Metallic Isolation Shell “Z” (zirconium oxide)E Secondary Sealing between the Anti-Friction Bearings “L”

Options

“Z“ Isolation Shell made of Zirconium OxideThis isolation shell generates no Eddy Cur-rent losses in the magnet drive. This isolation shell offers maximum pump efficiency and is particularly beneficial where heat input into the pumped liquid is to be avoided.

“L“ Secondary Sealing between the Anti-Friction Bearings

The secondary sealing consists of a high-performance radial shaft seal ring, which ensures that there is no immediate leakage of

the liquid to the atmosphere in the drive shaft area in the event of an isolation shell failure.

“E1F“ External Recirculation via Discharge FilterThe self-cleaning discharge filter is used for applications where liquids with a moderate percentage of solids are handled. The flush flow is picked up externally from the discharge filter and re-introduced into the magnet coup-ling. The internal flush flow ports are closed.

E Close-Coupled ConstructionE Construction without Flush Flow “OT“E Non-Metallic Isolation Shell “Z” (Zirconium Oxide)E Thermal Barrier with Secondary Sealing “W”

“W“ Thermal Barrier with Secondary SealingThe thermal barrier reduces heat transfer from the pump end to the anti-friction bear- ings. By using the thermal barrier, the temperature at the anti-friction bearings is reduced by 20°C to 30°C. A high-performance radial shaft seal ring is integrated in the thermal barrier as a secondary sealing. The gasket prevents immediate liquid leakage in the event of isolation shell failure.

“J“ InducerThe inducer is fitted in front of the impeller and increases the suction pressure. It offers enhanced NPSH characteristics to the pump

and can often almost half the NPSH require-ments.

“OT“ Construction without Flush FlowThis construction type is used for applications where liquids with a high percentage of solids are handled. The casing cover is equipped with two external connections for feeding and draining of the isolation shell area. The spe-cially designed journal bearings prevent any solids within the pumped liquid from entering the magnet drive.

E Plastic Isolation Shell CFRP/PTFE “C”

“H1“ Jacketed Hydraulic Casing for Heating“H2“ Jacketed Intermediate Lantern for HeatingThe heating jacket serves to heat the pump prior to starting or to maintain temperature.

“F“ Internal FilterThe self-cleaning internal filter is used for handling liquids with a low percentage of solids. The filter sits in front of the flush flow channel’s entry ports. It ensures that no solid matter that could damage the magnet drive or the journal bearing can enter the flush flow circuit.

“C“ Plastic Isolation Shell

The plastic isolation shell consists of two separate components – a carbon fibre rein-forced outer shell, and an inner PTFE liner. The shell eliminates Eddy Current losses and is used to maximise the pump’s over-all efficiency, or when a temperature rise of the internal flush flow must be avoided.
