Choosing an industrial motor gets tricky when the two motors on your shortlist look nothing alike. One is a complete, replacement-ready 5 HP severe duty motor with clearly spelled-out electrical specs. The other is a branded Gast motor/pump identified by model number. The right choice depends entirely on whether you need a general-purpose workhorse or a model-specific replacement.
Quick Verdict
Go with the 1800 RPM 5 HP Severe Duty Motor if you're replacing a motor and you already know your application needs a 184T frame. At $330.95, it costs $244 less than the $574.95 Gast. Choose the Gast 1000055624 when your equipment is built around that exact Gast motor/pump model and you want a Gast-branded unit.

Where Each Product Wins
The Severe Duty motor wins when you need a fully specified replacement motor. It includes a 25% overload capacity and a 1-1/8" keyed shaft, and the published specs cover the details that matter for demanding applications. If you're replacing a failed motor, this is the motor that gives you the most to work with before you buy.
The Gast wins on model specificity. It's a Gast-branded motor/pump with model number 1000055624, so if your equipment already uses that exact part, it's a direct replacement path. The unit is ready for service.
Product Notes
1800 RPM 5 HP Electric Motor 184T Frame TEFC 230/460V Severe Duty 3 Phase
This 5 HP motor is the one to choose when you need a replacement that comes with all the electrical details visible up front. The 184T frame, 1800 RPM rating, and dual 230/460V wiring make it a straightforward fit for many pump, compressor, and conveyor applications. The TEFC/IP55 enclosure is designed to resist dust and water, and Class F insulation helps it manage heat. The 1-1/8" keyed shaft is made from 1045 carbon steel, and the motor supports bi-directional rotation. The trade-off is physical: at 104 lbs it's a heavy piece to mount, and as a three-phase motor it needs a matching power supply. If your setup checks those boxes, this is the more fully specified option.
Gast 1000055624 Industrial Electric Motor / Pump
The Gast 1000055624 is a different kind of purchase. This is a model-identified industrial motor/pump from Gast, listed as new open box and made in the United States. If you know your equipment already uses a Gast motor/pump with this same model or MPN, this is a direct replacement option that doesn't leave you guessing about compatibility. The condition is new open box, so the unit is ready for service rather than being a used pull. The limitation is that you're buying a model-specific unit rather than a general-purpose replacement, so the right fit depends on whether 1000055624 is the number your equipment calls for. The Gast makes sense if you're dealing with a specific Gast-based machine, but it's not the motor to pick when you're sourcing a general-purpose replacement motor with published electrical ratings.
Final Choice by Use Case
Pick the Severe Duty Motor if you're sourcing a general-purpose replacement for a pump, compressor, or conveyor and want every electrical detail spelled out. It's the more fully specified of the two. Pick the Gast 1000055624 if you have a Gast motor/pump with the same model number and you need a model-matched replacement.
