Myers - 3RMW Series - Vortex Wastewater Pumps - Brochure

3RMW SERIES Vortex Wastewater Pumps 2TECHNICAL INFORMATIONTHE RIGHT CHOICEMyers 3RMW submersible wastewater vortex pumps are the right choice when difficult to pump fibrous or stringy solids are to be expected. The 3RMW series provides smooth, vibration-free operation over the entire performance curve. Myers offers a complete line of wastewater pumps, lift-out rail assemblies, controls and accessories to meet your needs. Call your Myers distributor or the Myers sales office at 419-289-1144 for more details.Passes stringy trash, fibrous wastes, slurries, and other difficult to pump solids that standard enclosed or semi-open impellers cannot.• Recessed impeller design has completely open passage in volute.• Operates without vibration or cavitation over entire performance curve. Operates near shutoff without harming pump.Durable motor will deliver many years of reliable service.• Recessed impeller greatly increases bearing life by reducing radial load.• Oil-filled motor for maximum heat dissipation and constant bearing lubrication.• Heat sensor thermostats embedded in windings protect motor from overheat conditions.• Seal leak probes warn of moisture entry; helps prevent costly motor burnout (dual seal only).Product CapabilitiesCapacities To 280 gpm 17.67 lpsHeads To 51 ft. 15.55 mSolids Handling175034502½ in.2 in.63.5 mm50.6 mmLiquids Handling raw sewage, effluent, rain waterIntermittent Liquid Temp. up to 140ºF up to 60ºCWinding Insulation Temp.
