Burks T350G6-1 1/2 Pump Cent 3Ph 5Hp TEFC Bronze Fitted End Suction Centrifugal Pump
The Burks T350G6-1 1/2 is a close-coupled end suction centrifugal pump built around a 5 HP three-phase TEFC motor, and it is the kind of pump people reach for when a job needs to run day after day without much fuss. The totally enclosed fan-cooled motor keeps dust, moisture, and airborne debris out of the windings, which makes it a sensible choice for plant floors, mechanical rooms, wash bays, and outdoor equipment pads where a drip-proof motor would have a short life. Because the pump and motor share a single shaft, there is no coupling to align and no separate base plate to shim, so installation is quicker and long-term maintenance is simpler.
Inside the cast iron casing is an enclosed bronze impeller running against a bronze wear ring, with a bronze shaft sleeve protecting the motor shaft — the bronze-fitted construction that gives this model its lasting reputation for handling clean water and mildly aggressive liquids without premature wear. The casing is stud-mounted and radially split, so the discharge can be rotated to any of eight positions to suit the piping instead of forcing the piping to suit the pump, and the back pull-out design lets a technician reach the seal and impeller without disturbing the suction and discharge connections. A self-adjusting mechanical seal with a carbon face and ceramic seat handles liquids up to 225°F.
With a 2 inch suction inlet, a 1-1/2 inch NPT discharge, and 3500 RPM operation, this pump delivers strong head in a compact footprint. It is a workhorse across HVAC and chilled water loops, cooling tower and condenser circulation, boiler feed and condensate return, general process and transfer duty, irrigation and booster service, and industrial washdown systems. Wired for 230/460 volt three-phase power on a 182JM frame motor, it drops into most existing commercial and industrial electrical systems with minimal modification.

Frequently Asked Questions
Q: Can the T350G6-1 1/2 be wired for either 230 or 460 volts?
A: Yes. The motor is dual-voltage three-phase, so it can be connected for 230 V or 460 V service by following the lead connection diagram on the motor nameplate. Confirm the overload settings on the starter match the full load amps for the voltage you select.
Q: Does this pump need to be primed before start-up?
A: Yes. This is a standard end suction centrifugal pump, not a self-priming model, so the casing and suction line must be filled with liquid before starting. A flooded suction arrangement or a foot valve with a priming connection is the usual solution.
Q: How do I know if the impeller is rotating in the correct direction?
A: Bump the motor and watch the fan or shaft end. Rotation should match the arrow on the pump casing. If it turns backward, swap any two of the three power leads at the starter. Running a centrifugal pump backward produces weak flow and can loosen the impeller.
Q: Can this model be repaired in place, or does the whole unit have to come out?
A: The back pull-out design lets you remove the motor and rotating assembly while the casing stays bolted to the suction and discharge piping. Seal and impeller service can be completed without disturbing the pipework or realigning anything afterward.
Q: What liquids is the bronze-fitted version suited for?
A: It is intended for clean, non-abrasive liquids such as water, condensate, glycol solutions, and light process fluids up to 225°F. Abrasive slurries, solids-laden liquids, and strong chemicals call for a different material specification.
