Burks 320GA5-1-1/4 Centrifugal Pump — 2 HP, 230V, 3-Phase
The Burks 320GA5-1-1/4 is a close-coupled, cast iron centrifugal pump built for shops, buildings, and light industrial operations that need steady, dependable water movement without a lot of fuss. Its 2 HP, 230-volt, three-phase motor runs at 3450 RPM and pairs with an enclosed bronze impeller to move water efficiently through the 1-1/2 inch inlet and 1-1/4 inch discharge ports, delivering up to around 60 GPM at 90 feet of head with a maximum shut-off head of 103 feet.
What makes this pump a practical choice is how well it balances everyday durability with straightforward maintenance. The close-grain cast iron casing and 302 stainless steel motor shaft stand up to continuous duty, while the carbon-face mechanical seal with buna elastomers keeps the pump running tight and leak-free across normal operating temperatures. Front and rear ball bearings and a built-in motor overload protector add extra peace of mind for operations that can't afford unplanned downtime.
Whether it's handling booster service, recirculation loops, general water supply, or washer line duty, the 320GA5-1-1/4 is designed to be dropped into an existing system and simply do its job. It's worth noting this pump isn't limited to any one industry — it shows up just as often in commercial buildings and light industrial water systems as it does anywhere else.

Frequently Asked Questions
Q: Is the Burks 320GA5-1-1/4 self-priming?
No, the 320GA5-1-1/4 is a close-coupled centrifugal pump and is not self-priming, so it should be installed with a flooded suction or a properly primed suction line for correct operation.
Q: Can this pump run on single phase power?
No, this specific model is built for 230V three-phase power only. Burks offers separate single-phase models in its G5 pump line for applications that require single-phase operation.
Q: What kind of liquids is this pump designed to handle?
The 320GA5-1-1/4 is designed for clean, non-corrosive water applications such as booster systems, recirculation, and general water supply, rather than for chemical, abrasive, or high-solids fluids.
Q: Does the motor include thermal overload protection?
Yes, the motor has built-in overload protection to help guard against damage from overheating or excessive current draw during operation.
Q: How is the pump mounted and coupled to the motor?
The 320GA5-1-1/4 uses a close-coupled design, meaning the pump impeller is mounted directly on the motor shaft rather than connected through a separate coupling and bearing frame, which keeps the footprint compact.
