ROTAN® EDEnvironmental Duty Pumps Key features and benefits • Reversible direction of flow with double acting relief valve option available • Coupled direct to NEMA or IEC motor for speed up to 1750 rpm • Directed coupled gearbox with NEMA or IEC electric motor eliminating alignment issues • Adjustable rotor end clearance without opening the system to the atmosphere • Torque capabilities in excessive of 800 ft-lb • Flow rates max. 90 m3/h with differential pressure up to max. 16 bar. • Iron, Steel and Stainless Steel construction • Tungsten Carbide abrasive wear materials are available for abrasive duty applications Magnetically coupled pumps for ultimate protection against leakage. As only minimal maintenance is necessary, ED pumps will be a very economical solution compared with traditionally sealed pumps, especially where the application requires the use of double mechanical shaft seals. Often these applications are very different, resulting in the seals and support system requiring regular attention and/or replacement. Thus, the life cycle costs for ED pumps are generally much lower than for pumps using two seals. Available with 90° angular configuration.

Selection of Pump size PLEASE NOTE! ED: Capacity curve up to 151 GP: Capacity curve up to 101 To select the pump size with this table, you should only know: - The capacity - The viscosity We start at the top of the table with the viscosity, and draw a line down, staying within the colour of the selected viscosity range (see example). Then we start at the right of the table, drawing a horizontal line starting with the required capacity (see example). The point where these two lines meet determines the pump size, defined by the diagonal lines in the table. If you do not hit one of these pump...
