THE MYERS MW50 SERIES SEWAGE PUMPS PRO- VIDE BIG PERFORMANCE IN A SMALL PACKAGE. The enclosed two -vane impeller provides the flow and head required for residential and light commercial sewage applications, and passes a full 2" diameter solid. The MW50 is constructed of only the highest quality corrosion resistant mate- rials - cast iron, stainless steel and engineered thermoplastics - for many years of service in harsh sewage environment. The MW50 is avail- able in manual models for use with external controls Or automatic models with piggy -back mechanical float. For more information, call your Myers distributor or the Myers, Ashland, Ohio, sales office at 419-289-1144. ADVANTAGES BY DESIGN TWO VANE IMPELLER DESIGN PROVIDES MAXIMUM EFFICIENCY ■ Enclosed design for high efficiency pumping. ■ Eliminates possibility of jamming between impeller and volute. ■ Passes a full 2 inch solid. ■ Original performance can be restored If wear occurs by replacing volute seal ring.
