Burks EC9M Turbine Pump Only – Base Mounted Regenerative Turbine Pump End
The Burks EC9M is a base mounted regenerative turbine pump end supplied as a pump only, which means it arrives without a motor, coupling, base plate, or coupling guard. That makes it the practical choice when you already have a drive package in place and simply need to replace a worn hydraulic end, or when you are building a custom skid and want to pair the pump with a motor you have specified yourself. It handles clean, non-corrosive, non-abrasive, low-viscosity liquids, and its regenerative turbine design produces far higher head at modest flow than a comparably sized centrifugal pump.
Construction follows the bronze-fitted pattern Burks has used for decades. The close-grain cast iron casing is rated to 200 PSI, the bronze impeller carries monel metal blades secured in machined slots, the shaft is 303 stainless steel, and the raceway is bronze. A self-adjusting mechanical shaft seal handles service temperatures up to 225°F, and the Life-Lok® external adjustment feature lets a technician reset impeller-to-raceway clearance without pulling the pump apart, which restores performance in minutes instead of hours. Flow spans roughly 12 to 29 GPM against heads from about 20 to 360 feet, depending on the speed and driver you match to it.
Typical duty for the EC9M includes boiler feed, condensate return, heat transfer fluid circulation, pressure boosting, and general liquid transfer in industrial plants, commercial buildings, laundries, car washes, and process lines. Once the casing is filled, the pump will move water, air, or a mixture of both, so it recovers well on systems that occasionally lose prime. For hotter service, jacketed seal cavity variants extend the temperature range considerably.

Frequently Asked Questions
Q: Does the Burks EC9M come with a motor?
A: No. The EC9M is sold as a pump end only. The motor, coupling, base plate, and coupling guard are separate items and must be quoted or supplied on their own.
Q: Can the EC9M be used as a drop-in replacement for an existing Burks EC Series pump?
A: Yes, in most cases. Because the EC9M shares the standard EC Series base mounted footprint and NPT port sizes, it is commonly fitted to existing packages when the original hydraulic end is worn out. Confirm shaft bore and coupling fit before ordering.
Q: What does the Life-Lok® external adjustment actually do?
A: Over time the running clearance between the impeller and the raceway opens up and performance drops. Life-Lok® lets a technician reset that clearance from outside the pump, so output is restored without breaking down the assembly.
Q: What liquids should not be run through this pump?
A: Avoid abrasive slurries, corrosive chemicals incompatible with cast iron, bronze, or Buna-N, and high-viscosity fluids. Regenerative turbine pumps rely on tight internal clearances, and particulates will wear those clearances quickly.
Q: Is a higher temperature version available?
A: Yes. Jacketed seal cavity variants, identified by a J or JK suffix, extend the usable temperature range well above the standard 225°F limit for hot oil and high-temperature circulation duty.
