ET

Burks Series ET turbine pumps are available for capacities up to 8 GPM (0.50 l.p.s.) - pressures up to 150 p.s.i. (1034 kPa) and temperatures up to 225°F (107°C), with standard mechanical shaft seal. Special shaft seals are available for higher temperatures and fluids other than water.

These compact turbine pumps are designed for pumping clear water and many other non-abrasive, lower viscosity liquids. They are especially engineered for boiler feed on steam process applications and will serve up to a 38 HP boiler at a 3 to 1 safety factor. Available in bronze fitted as standard. All bronze or stainless steel construction also available. These pumps are recommended for many application requiring higher pressures and lower capacities.

Burks ET Series Regenerative Turbine Pumps

High-Pressure Performance for Boiler Feed and Process Applications

The Burks ET Series regenerative turbine pumps are engineered for applications requiring high pressure at relatively low flow rates. Designed specifically for boiler feed systems, condensate return, pressure boosting, heat transfer operations, and industrial process applications, the ET Series provides exceptional pressure generation in a compact, base-mounted pump design.

Using regenerative turbine technology, the ET Series can develop significantly higher heads than comparably sized centrifugal pumps, making it an ideal solution for systems where pressure performance is more critical than flow volume. Built for continuous-duty operation, these pumps deliver reliable service in demanding commercial and industrial environments.

The ET Series is specifically engineered to provide reliable performance in systems where high head pressure is required but flow demands remain relatively modest.

Exclusive Life-Lok® Adjustment System

A distinguishing feature of the Burks ET Series is the exclusive Life-Lok® external impeller adjustment system.

Benefits of Life-Lok® Technology

• Restores pump performance without disassembly

• Eliminates the need to disconnect piping

• Reduces maintenance costs and downtime

• Extends impeller and pump life

• Maintains hydraulic efficiency throughout the life of the pump

• Provides up to 40% longer service life compared to conventional turbine pump designs

Material Construction Options

The ET Series is available in several construction materials to meet varying application requirements.

Available Materials

• Bronze-Fitted Cast Iron

• All Bronze

• Stainless Steel

These options allow the pump to be matched to fluid compatibility requirements and specific operating environments.

Optional High-Temperature Service

For hot water, heat transfer fluids, and thermal oil applications, the ET Series is available with an optional Jacketed Seal Cavity design. This configuration helps extend seal life in elevated-temperature systems and supports operating temperatures up to 500°F in appropriate applications.

Designed for Boiler Feed Applications

The ET Series is particularly well suited for boiler feed service, where reliable pressure generation is critical. These pumps are capable of supporting boilers requiring substantial discharge pressure while maintaining a compact footprint and straightforward maintenance access.

Typical Applications

• Boiler feed systems

• Condensate return systems

• Steam process applications

• Pressure boosting systems

• Heat transfer fluid circulation

• Hot water systems

• Industrial process equipment

• Water treatment systems

• Chemical handling applications

• Spray systems

• General high-pressure liquid transfer
