EC / ED Series

EC / ED Turbine Pumps Pump

EC / ED Turbine Pumps Base Mounted Pump Series
General Information
BURKS EC / ED Turbine Pumps are designed for many pumping applications. Any clean, non-corrosive, non abrasive lower viscosity liquid on low flow and also, high head applications. They are used in a wide range of industries.
  • Boiler Feed Systems.
  • Condensate Return.
  • Heat Transfer.
  • Hot and Cold Water Circulation.
  • Jockey Pump.
  • Hydraulic Oil Circulation.
  • High Pressure Spray.
  • Brine Circulation.
  • Pressure Booster.
  • Additive Metering.
Base Mounted Turbine Pumps
  • Pump Shaft 303 Stainless Steel.
  • Power Frames - Power frames are supplied with grease lubricated ball bearings. Wide bearing spacing provides solid shaft support. Tapped and also plugged openings are conveniently located for easy relubrication of power frame. Grease relief holes prevent over-lubrication.
  • The bronze impeller, with monel metal blades secured in slots in the liquid channel by means of a brazing process, as a result  is the only moving part. Annular grooves or sealing rings are machined in the face of the impeller. These grooves are perfectly matched with corresponding grooves in the raceway and intermesh without metal to metal contact to form a labyrinth seal.
  • Raceway. The bronze raceway is the mating part to the impeller. Sealing grooves are machined into the face of the raceway to match the impeller sealing grooves. First of all this is reducing water slippage to a minimum, resulting in better efficiencies, while reducing the possibility of vapor bind.
  • Mechanical Shaft Seal. The same leak proof mechanical shaft seal for temperatures to 225°F (107°C), is self-adjusting. A wide variety of mechanical seals are available for handling liquids other than water.
  • Casing is close grain iron of 30,000 PSI minimum tensile strength. Should the pump require service there’s no need to disturb the piping since the casing stays in the line.
  • Self Priming Once casing is filled with water will handle water, air or a mixture of both to high pressure.
  • Factory Tested - Hence Every pump factory tested for capacity, head and power consumption.
Life-Lok® External Adjustment
An adjusting screw is located in the power frame on Independent Pumps. A positive pre-load spring pressure is applied to the pump shaft bearing and in turn, is transmitted to the adjusting screw. This controlled pressure eliminates bearing end-play and provides a means for external adjustment of the clearance between the impeller and raceway. The distinct advantage of this exclusive BURKS feature is the positive means provided while to establish the initial clearance between the impeller and raceway. Plus providing a means for external readjustment as a result to also compensate for any possible wear between these parts. Burks customers will also benefit of this exclusive feature. Customers love the fact that readjustment can finally be made without disassembling the pump or disturbing the piping.
Jacketed Seal Cavity For Temperatures to 500 °F (260 °C)
Our Series EC and ED Pumps are available in a Jacketed Seal Cavity design as a result for pumping hot oil, hot water and heat transfer fluids in common use in high temperature heating or cooling applications. This feature greatly extends seal life in high temperature applications. To order, add suffix “J” to pump catalog number for temperatures below 400 °F (204 °C) and add suffix “JK” to pump catalog number due to temperatures over 400 °F (204 °C). Example: EC6MJ. In conclusion, See Section on High Temperature Pumps for more information. ED9M-AB Burks Pump
