Shopping for industrial motors isn't just about picking the one that spins. You need to match voltage, phase, frame size, and RPM to the equipment you're running, and you also need to decide how much specification certainty you require. These two options sit at opposite ends of that trade-off: a fully specified 2 HP 56C-frame 3-phase motor, and a Gast industrial motor/pump that leaves the specs to the label.
The Quick Verdict
If you need a documented replacement motor with detailed electrical and mechanical specs, the 2 HP motor is the straightforward choice. If you're shopping for a new open-box Gast motor/pump and you're comfortable identifying the unit from its physical label, the Gast is worth your attention.
Price & Spec Snapshot
| Product | Price | Price Bar | Key Info |
|---|---|---|---|
| 2 HP 56C Frame Motor | USD 175.10 | Listed as 2 HP, 3-phase, 56C frame, 1800 RPM, 230/460V | |
| Gast 1000055624 Motor/Pump | USD 574.95 | Model number, new open box, US origin; specs left to the item label |
The price difference is significant, and the spec difference is even more important.
Where Each Product Wins
The 2 HP motor wins when you need a clearly specified replacement and want the electrical and mechanical details spelled out before you commit. The Gast wins when you want a new open-box unit with a model number and US origin, and a missing spec list isn't a dealbreaker for your project.
For a replacement motor on existing equipment, you typically need to match frame, voltage, phase, and RPM precisely. The 2 HP unit gives you all of those details upfront. For a project build or a less defined need, the Gast unit can work if you can identify it from its label, but it requires more hands-on investigation.
Product Notes
2 HP 56C Frame 3-Phase Motor
If your equipment expects a 3-phase, 1800 RPM motor, this unit gives you a high level of spec confidence. The listing spells out a TEFC enclosure, Class F insulation, a C-face removable base, a keyed shaft, and a 230/460V connection. It also notes the motor is fan-cooled and features a heavy-duty design, which adds to its usefulness in industrial settings. At $175.10, it's a much easier price to absorb than the Gast. The limitation is that it's listed as non-reversible and not protected against liquids, so don't install it where you need reverse rotation or wet-environment resistance. For a straightforward replacement on a compatible machine, those trade-offs are easy to live with.
Gast 1000055624 Industrial Electric Motor / Pump
The Gast is a new open-box unit with a clear model number and US origin. The Gast name and model number give it a clear identity, and it's listed as ready for service. The trade-off is that the listing doesn't detail the motor's horsepower, phase, or voltage, so the physical label becomes the source of truth for confirmation. That makes it a more open-ended purchase than the 2 HP motor, and it's the right choice only if you're comfortable with that level of uncertainty. For a strict replacement job, this Gast would be harder to commit to sight unseen.
Final Choice by Use Case
For a known replacement: Go with the 2 HP 56C Frame Motor. Its listed spec set covers the key electrical and mechanical details you need for a replacement.
For a Gast-specific project: Choose the Gast 1000055624. It's a new open-box unit with a model number and US origin, and it gives you a known manufacturer.
For maximum information: The 2 HP motor gives you far more detail before you buy, so it's the safer recommendation if you can't physically inspect the unit first.
