Compatibility & Fitment
FS-Curtis currently uses the E57 pump in multiple CA Series configurations. Pump compatibility should be confirmed by the complete compressor model and serial number because drive speed, motor horsepower, control arrangement, and package configuration vary between compressors.
| CA Series | Power | Pump |
|---|---|---|
| CA5+ | 5 HP | E57 |
| CA7.5 | 7.5 HP | E57 |
FS-Curtis also uses the E57 pump in selected duplex and gas-driven CA Series configurations. Confirm the exact compressor model and serial number rather than selecting a pump by horsepower alone.
Before Installation

- Verify that the existing compressor uses the E57 pump family.
