Burks ES Series Regenerative Turbine Pumps

High-Pressure Pumping Solutions for Demanding Process Applications

The Burks ES Series regenerative turbine pumps are designed for applications where high discharge pressure is required but flow demand remains relatively low. These base-mounted pumps provide exceptional pressure-building capabilities in a compact footprint, making them an ideal choice for boiler feed systems, condensate return, pressure boosting, heat transfer processes, and specialized industrial applications.

By utilizing regenerative turbine technology, the ES Series develops significantly higher pressures than conventional centrifugal pumps of similar size, helping facilities achieve consistent performance while reducing installation complexity.

Key Features

• Base-mounted regenerative turbine pump design

• High-head, low-flow hydraulic performance

• Self-priming capability for improved operating flexibility

• Exclusive external impeller adjustment system for extended pump life

• Bronze impeller with durable Monel blade construction

• Heavy-duty bronze raceway design

• Carbon ceramic mechanical seal for dependable sealing performance

• 303 stainless steel shaft for corrosion resistance

• Easy-access design simplifies maintenance procedures

• Factory-tested construction for performance verification

• Available in bronze-fitted, all-bronze, and stainless steel configurations

Performance and Connection Sizes

The ES Series is specifically engineered for pressure-intensive applications that require reliable operation and long service life.

Performance Highlights

• Flow capacities up to approximately 50 GPM

• Heads up to 350 feet

• Horsepower options from 1/3 HP to 5 HP

• 1-1/4" NPT suction connection

• 1" NPT discharge connection

• Available in 1725 RPM and 3450 RPM configurations

• Maximum liquid temperatures up to 225°F with standard seal materials

• Maximum inlet pressure of 100 PSI

• Maximum casing working pressure of 250 PSI

The compact connection sizing makes the ES Series particularly well suited for boiler rooms, package systems, skid-mounted equipment, and industrial process installations where space is at a premium.

Advanced Pressure Generation

Unlike traditional centrifugal pumps that prioritize flow volume, the ES Series is designed to maximize pressure generation. This makes it an excellent solution for systems that require steady pressure delivery across long piping runs, elevated equipment, or pressure-sensitive process operations.

Its regenerative turbine design continuously recirculates liquid through precision-machined channels, allowing pressure to build progressively with exceptional efficiency.

Simplified Service and Reduced Downtime

The ES Series incorporates Burks' exclusive external impeller adjustment system, allowing performance adjustments without removing piping or disassembling the pump. This feature helps restore efficiency, reduce maintenance costs, and extend service life while minimizing downtime.

Combined with its straightforward mechanical design, the result is a pump that is both reliable and easy to maintain throughout its lifespan.

Optional High-Temperature Configurations

For hot water, thermal fluid, and heat transfer applications, the ES Series can be configured for elevated-temperature operation. These options help protect critical sealing components and improve reliability in demanding thermal systems.

Typical Applications

• Boiler feed systems

• Condensate return systems

• Pressure boosting

• Heat transfer circulation

• Hot water recirculation

• Water treatment equipment

• Reverse osmosis systems

• Spray and misting systems

• Industrial process fluid handling

• OEM equipment packages

• General high-pressure liquid transfer
