|Mechanical Shaft Seal Information|
|The leakproof 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.|
|Every pump factory tested for capacity, head and power consumption.|
|Jacketed Seal Cavity|
|Series EC & ED Pumps are available in a Jacketed Seal Cavity design for pumping hot oil, hot water and heat transfer fl uids 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 for temperatures over 400°F (204°C). Example: EC6MJ.

|Power frames are supplied with grease lubricated ball bearings. Wide bearing spacing provides solid shaft support. Tapped and 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, 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.|
|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 reducing water slippage to a minimum, resulting in better efficiencies, while reducing the possibility of vapor bind.|
|The 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 to establish the initial clearance between the impeller and raceway, plus providing a means for external readjustment to compensate for any possible wear between these parts. The customer benefit of this exclusive feature is the fact that readjustment can be made without disassembling the pump or disturbing the piping.|
|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 - the casing stays in the line.|
|Once casing is filled with water - will handle water, air or a mixture of both to high pressure.|
