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.

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, www.thompsonpump.com.Enquiry No. 58
