Burks ES9M Turbine Pump – Base-Mounted Self-Priming Pump End
The Burks ES9M is a rugged, base-mounted turbine pump end built for facilities that need dependable performance in demanding high-pressure, low-flow situations. Sold as a pump-only unit, it's designed to pair with a compatible motor through a long coupling, giving maintenance teams flexibility when replacing or upgrading equipment without having to rebuild an entire pump-and-motor assembly from scratch.
Constructed with a bronze-fitted cast iron body, a bronze impeller with Monel blades, and a 303 stainless steel shaft, the ES9M is engineered to hold up under sustained use in boiler rooms, mechanical rooms, and process areas. Its self-priming design means it can pull liquid without manual priming, and the carbon/ceramic mechanical shaft seal keeps operation reliable at temperatures up to 225°F, or as high as 500°F when paired with the optional jacketed seal cavity for hot oil or heat-transfer fluid service.
What sets the ES9M apart from many competing turbine pumps is the Life-Lok external impeller adjustment feature, which lets technicians fine-tune impeller clearance from outside the pump housing, without disconnecting piping or tearing the unit down. Combined with its resistance to vapor lock and a service life that Burks rates well above typical turbine pump designs, the ES9M is a practical choice for facilities looking to reduce downtime and simplify long-term maintenance.

Frequently Asked Questions
Q: Does the Burks ES9M come with a motor included?
No. The ES9M is sold as a pump end only. It's designed to be coupled to a separately purchased motor using a long coupling, along with a coupling guard, which is not included with the pump.
Q: What kind of liquids can the ES9M handle?
The ES9M is intended for clear, non-abrasive liquids such as water, condensate, and similar fluids used in boiler feed, cooling tower, and general circulation service, within its rated viscosity and temperature limits.
Q: How does the Life-Lok feature simplify maintenance?
Life-Lok allows the impeller clearance to be readjusted from outside the pump casing, so technicians can restore performance as wear occurs without disconnecting piping or fully disassembling the unit.
Q: Can the ES9M handle high-temperature fluids?
Yes, with the standard Buna-N seal it's rated to 225°F. For hotter fluids such as hot oil or heat-transfer fluid, an optional jacketed seal cavity design extends the temperature rating up to 500°F.
Q: Is the ES9M suitable for marine use only?
No. While turbine pumps are sometimes associated with marine service, the ES9M is primarily used in commercial and industrial settings such as boiler rooms, mechanical rooms, and process facilities, not exclusively marine environments.
