![]() How the E/One pump curve compares to centrifugal grinder pumps. What's Different about the E/One Grinder Pump vs Other Grinder Pumps? Higher velocity wheels wear faster and produce less stirring, leading to more retained sediment in the tank. Small, 2.5-in (63.5 mm) diameter cutter wheels have a much higher inlet velocity of 22 ft/sec (6.94 m./sec), which leads to increased jamming, binding, and suffocating. Slicers do not function properly once blade edges are dulled. The paddles on E/One’s cutter wheel stir the wastewater, which helps keep the tank clean and prevents sediment build up.Į/One’s grinder does not require sharpness to function properly and is a true macerator as opposed to a slicer. How is the E/One SPD Pump Different from Centrifugal Pumps?Į/One’s low speed, high torque, 5.25-in (133 mm) wheel has an inlet velocity of 3.6 ft/sec (1.09 m./sec), which slowly introduces the debris into the cutter and is less likely to jam, bind, or suffocate. ![]() Pump Diagram Drawingsĭownload the parts diagrams for Extreme Series grinder pumps and level sensor assemblies. The E/One pump requires a minimum of 216V to start and run reliably. 1 pump HDPE tank 100 gal capacity 700 GPD. Stations are available with up to four pumps, depending on the tank chosen. A range of basins (PE or fiberglass), covers, discharges, inlets and alarm panels are available. If only 208V power is available, a buck boost transformer is required to boost 208V to 240V. The W-Series is E/One's most flexible product line. Motor: 1 HP, 1725 rpm, high torque, capacitor start, thermally protected, 240 or 120 volt, 60 hertz, 1 phaseĭownload the E/One Extreme pump curve Electrical Informationįor a standard 240V single-phase installation, a dedicated 30A breaker is required, with #10 wire, to the E/One panel. More information: E/One Extreme Series brochure Operational Information (Actual water and power usage will vary depending on the system pressure.) Electrical consumption is low - a household that uses 250 gallons of water per day should use between 6 kwhr and 23 kwhr per month to run the pump. The grinder pump turns on and off automatically and runs for very short periods several times per day.
