SEV and SE1 ranges 1.1 – 11 kW - Industrial Pumping

1 SEV and SE1 ranges 11 kW now with analogue sensorsGRUNDFOS WASTEWATERG rundfos SEV and SE1ranges>2 Highly advanced pumps with many unique featuresThe grundfos SEV and SE1 ranges are technologicallyvery advanced pumps designed to handle wastewater,process water, and unscreened raw sewage in heavy-duty municipal, utility, and Industrial monitoring of pump conditions at any giventime, pumps are available with analogue heavy-duty pumps are built for years of trouble-free operation in the most demanding pumps may be installed submerged or dry with-out motor cooling; in either case they are extremelyreliable and very easy to efficient single-channel or SuperVortex impellersprovide free passage of solids up to 100 mm.

2 Thisgreatly reduces the risk of clogging and ensures maxi-mum up-time and reduced operating costs.>Unique liquid-less motor coolingA solid-block stator housing transfers excessheat to the pumped liquid in the pump allows for continuous operation in partlysubmerged or dry installations. No cooling liquidis needed.>Unique cable entryA polyurethane-filled stainless steel cable con-nection provides a hermetically sealed cable totallyeliminates the risk of water enteringthe motor through the cable.>Unique cartridge shaft sealPrimary and secondary mechanical shaft seals are fitted in a single, easy-to-replace compactcartridge unit.>Unique modular designThe SEV and SE1 ranges are designed for maxi-mum flexibility.

3 The detachable motor units areinterchangeable and fit both channel impellerand SuperVortex pumps.>Analogue sensors constantmonitoring of pump conditionsThe analogue sensors in the SEV and SE1 pumpsconstantly monitor pump conditions and giveexcellent opportunities to carry out preventivemaintenance thus eliminating unscheduleddowntime. Type of sensors are shown on page >3 The grundfos range of heavy-duty sewage pumps, SEV and SE1, can be permanently installed by means of anauto-coupling guide-rail system or with a fixed pipe connection, submerged or dry without separate motorcooling arrangements. The pumps are also suitable for free-standing installation, or as portable utility free-standing installation, or portable useFitted with an optional ring stand, the pumps may beinstalled free standing in a pump pit, or they can be usedas portable utility pumps in non-permanent dry installation Due to the efficient liquid-less motor-cooling system, the SEV and SE1 pumps are suitable for dry installation either vertically or horizontally to suit specific application dry installation Horizontal dry installation improves the overall efficiencyof the system as unnecessary components and bends are avoided.

4 Special mounting brackets are available for horizontal installation on auto-coupling with guide railsWhen installed on an auto-coupling system, the pumpautomatically connects to a base unit fixed to the bottomof the pump technology inside outThe grundfos SEV and SE1 pumps feature advanced technology inside out. In spiteof their good looks, these highly efficient pumps are designed for years of trouble-free operation in the toughest environments. Easy to install and easy to service,the SEV and SE1 pumps ensure low long-term operation rotor shaftCompact motor construction with short rotor shaft reduces efficiency and lifetime ofshaft seal and ball cable connectionPolyurethane-filled stainless steel cableconnection, hermetically that liquid cannot penetratethrough the cable into the cable lengths are motor coolingSolid-block stator housing with built-in cooling conduits, which efficientlytransfer excess heat to pumped liquidvia a solid cast iron cooling allows for continuous operationeven in dry mechanical shaft sealEfficient single-unit cartridge shaft sealsystem ensures longer operation timeand lessdowntime.

SmartSealThe patented grundfos SmartSeal,mounted on the guide claw,provides a leak-proof connection,which optimises theefficiency of the pump system and keeps running cost at a SuperVortex-impeller pumpsSuperVortex impeller >6A unique impeller designThe design of the grundfos SuperVortex impelleris truly unique. The special blade vanes ensurehigh Pumping efficiency and excellent air eva-cuation while preventing clogging or on pump model, the SuperVortex-impeller allows for free passage of solids of 65 mm,80 mm, or 100 mm grundfos SEV pump range with SuperVorteximpeller is the ideal choice for applications whereabrasive liquids, large quantities of solids, gassysludge, or fibres are clogging or jammingIn a pump fitted with a grundfos SuperVorteximpeller, the flow takes place entirely outside theimpeller making these pumps ideal for handlingheavy and gassy sludge.

7 Long fibres, rags andother solids pass freely through the pump with-out getting caught by the impeller so that clog-ging or jamming are avoided. This means lessdown-time and, consequently, reduced serviceand turbulent disturbanceIn pumps fitted with conventional vortex impel-lers, turbulent disturbance is liable to form aroundthe impeller. This will disrupt the flow patternand result in reduced Pumping efficiency andlower head. With the grundfos SuperVortex impeller, theliquid passes freely outside the impeller withoutgenerating any turbulent disturbance. grundfos channel-impeller pumpsChannel impellers >7 Ideal for large flowsThe grundfos channel impellers provide highefficiency and excellent non-clogging on pump model, the channel impellersallow for free passage of solids of 50 mm, 80 mm,or 100 mm SE1 pumps with a 80 or 100 mm channelimpeller are ideal for large flows of raw wear ringThe design of the channel impeller with a replace-able steel wear ring and the corresponding rubberseal ring on the pump housing makes the pumpmore resistant to wear caused by abrasives inthe pumped system enables maintaining maximumpumping efficiency for extended periods withoutreplacing the impeller.

8 The result is less cloggingand less free passage The grundfos channel impellers are of a semi-axial design with extra long vanes. This ensuresmaximum performance and eliminates problemswith fibres getting caught in the impeller, liableto cause clogging. The grundfos SE1 pumps arecapable of handling solids up to 100 mm size.
