The Myers SPD50H/100H series of effluent pumps are completely submersible pumps that are specifically designed to meet the demands of septic tank effluent applications that demand a high-head, dual seal pump. Standard discharges for this series are 2” NPT though 3” discharges are also an available option. The SPD50H/100H series features both manual and automatic models. The SPD50H can handle capacities up to 110 gallons per minute and heads to 50 feet, while the SPD100H handles capacities up to 140 gallons per minute and heads to 63 feet. Oil filled motors provide superior cooling, allowing motors to run cool and quiet for years. SPD50H models come with a powerful ½ HP motor while SPD100H models come with a 1 HP motor. These pumps feature a high quality cast iron pump volute, motor housing and seal housing construction that ensures a long service life. A threaded non-clogging, two vane cast iron impeller is capable of handling spherical solids up to 3/4 “. A seal failure sensor probe comes standard on 3 phase unites and are available as an option on single phase models. All these features are sure to guarantee the dependability you’re looking for in your pump. Features Water-resistant power cord has a compression-fit connection and an epoxy potting for double protection against water entry Oil-filled motor provides superior cooling and permanent lubrication of bearings, minimizing maintenance and extending service life High-quality cast iron construction of pump volute, motor housing and seal housing provides long life Upper radial- and lower thrust bearings are heavy-duty, single row ball bearings that are permanently lubricated for service free life Two carbon- and ceramic-faced mechanical shaft seals are mounted in tandem to provide double protection against water entry for a long, leak proof life Bottom inlet has no screen to become clogged, providing optimum pump performance and minimal maintenance Applications Septic tank effluent High-head dewatering High-capacity sump MYERS SPD50H/100H SERIES EFFLUENT PUMPS Model Comparison Chart Model Discharge (NPT Vertical) HP Voltage Phase GPM Max.
