Description
Burks 315G6-1-1/4 Centrifugal Pump
The Burks 315G6-1-1/4 centrifugal pump is a 1.5 HP, three-phase, 60 Hz close-coupled end suction centrifugal pump with a 208/230/460V ODP motor. It is commonly used for water circulation, cooling water service, cooling tower systems, HVAC circulation, booster service, liquid transfer, and commercial water transfer applications where the required duty point falls within the pump curve.
The G6 Series is designed for dependable water transfer and circulation in commercial and industrial systems. The motor-mounted design provides a compact installation and simplifies service compared to traditional base-mounted pump assemblies.

Installation & Selection Tips
Confirm your electrical supply matches the three-phase 208/230/460V motor configuration. Ensure suction and discharge piping matches the listed NPT sizes to support the rated capacity range. Verify that the required duty point falls within the approximate 10–70 GPM and 40–75 ft head performance range.
For cooling tower, HVAC circulation, water transfer, or booster service, confirm the system flow rate, total dynamic head, fluid temperature, suction conditions, and available NPSH before ordering. For complete boiler room packages, see our condensate return systems.
Frequently Asked Questions
What motor configuration does this pump use?
This pump uses a 1.5 HP, three-phase, 60 Hz, 208/230/460V ODP motor.
What are the connection sizes?
Suction is 1-1/2″ NPT and discharge is 1-1/4″ NPT.
What performance range does this pump cover?
The approximate curve range is 10–70 GPM with head from about 40–75 feet, depending on system conditions and duty point.
Can this pump be used for cooling tower or water circulation service?
Yes. The Burks 315G6-1-1/4 may be used for water circulation, cooling water, cooling tower, HVAC circulation, liquid transfer, and booster service when the system duty point matches the pump curve.
Can this pump be used for condensate return or boiler feed applications?
Yes, but only when the required flow, head, temperature, suction conditions, NPSH, controls, and system requirements are within the pump limits.
