Mixer mounts to bulk containers, totes

Neptune Mixer’s new Series HGL (430 RPM) mixers allow easy integration with standard intermediate bulk-containers (IBCs) or poly tote bins by use of an optional 2” 316SS bulkhead fitting. The mixer features a short shaft and folding propeller that are constructed of 316SS and capable of fitting through a 2” opening; the prop’s operating diameter is 9”. A second folding propeller can be added as an accessory and bolted anywhere on the 3/4” dia. shaft. Motors available include TEFC electric motors (1/3 to 1 HP) or air motors (1/2 to 1 HP). Explosion-proof motors are also available. Neptune Mixer Company, Lansdale, Pennsylvania, USA, No. 53

Sewer pipe rehabiliation liner

Today’s piping rehabilitation technology eliminates the need to dig trenches due to efficiency, fastness and eco-friendliness of relining procedures. The starline®3000 UV technology is based on a UVA light curing technique. The seamless Brandenburger GFRP Liner cures to a “pipe in pipe” for efficient sewage system renewal. With simple preparatory works and extremely short curing times, rehabilitation projects’ energy consumption and styrene emissions are kept to a minimum. Projects of up to 250m of sewer pipes can be done in one workday. Karl Weiss Group, Berlin, Germany, No. 54

Mouvex, a member of Dover Corp.’s Pump Solutions Group (PSG™), introduced its new SLC-Series line of eccentric disc pumps at the 2009 ACHEMA event in Germany. Ideal for shear sensitive products or where there are leakage concerns as well as for handling thin, abrasive, aggressive and higher viscosity fluids, it provides superior volumetric efficiencies and overall energy savings in a seal-less, self-priming pump. It’s used in multiple fluid-handling applications within chemical processing and distribution industries. The pump comes in stainless steel and ductile iron models able to handle up to 10,000 cst (46,000 SSU) liquids at pressures up to 130 psi (9 bar). Mouvex-Blackmer, Auxerre, France, No. 55

3-phase MOTOR soft-starter

The new RSHL Smart soft-starter features a low power-consumption design and integrated heat sink. Its electronic motor overload protection replaces traditional Star-Delta (Wye-Delta) solutions with a single, compact module. The 45mm-wide unit can be DIN-rail mounted in space-conscious enclosures. It offers improved start/stop performance, more start cycles, electronic motor protection, monitoring and diagnostics. With 220, 480 and 600VAC versions, it controls three-phase induction motors rated to 11kW for pumps, compressors, fans, hydraulic systems, conveyors and industrial machinery. Carlo Gavazzi UK Ltd, Aldershot, UK, No. 57

10” centrifugal pump

The 10JSCE Enviroprime® Pump is a 10” automatic priming centrifugal pump with flows to 4,400 gpm and heads to 220 feet. The pump handles solids up to 3.38” and is ideal for sewer by-pass pumping, emergency flood response, and other applications requiring transfer of solids-containing liquids. Unlike most automatic priming systems, it prevents product blow-by of pumpage, such as sewage effluent and waste, from being discharged on the ground or through hoses that carry it back to the source. Durable and highly efficient pump ends provide longer life, economical operations, and lower fuel costs. Thompson Pump & Manufacturing, Port Orange, Florida, USA, No. 58

Camlab’s CW7000 BOD sensor system is a six-sample, direct-reading instrument to enable precise measurement of biological oxygen demand using manometric respirometers. The mercury-free system offers direct sample selection and integrates user-friendly features to simplify a complex measurement procedure and lower operating costs. These include capability to display all BOD results directly in mg/L without need for time-consuming conversions. The measuring period also can be user-selected at 1 and 28 days (BOD5, BOD7, OECD). It ranges from 0-40 mg/L to 0-4000 mg/L BOD/sample volume related with automatic storage of BOD values. Camlab Ltd, Over, Cambridge, UK, No. 59
