Godwin® CD Series (Dri-Prime®)
APCD Auto-Prime Series compared with Godwin® CD Series (Dri-Prime®)
If you already run Godwin® CD Series pumps, you do not have to replace the fleet to change parts supplier. AMCO's APCD Series is built to the same fits and dimensions, so parts drop into the pumps you own — and when a unit does need replacing, the AMCO model numbers mirror the CD numbering.

Auto-prime notes
Every APCD unit is a dry-prime, diaphragm-assisted vacuum pump: the compressor-driven priming system pulls air out of the suction line so the pump primes and re-primes itself without an operator at the unit.
- Fully automatic dry prime — the vacuum system evacuates the suction line and shuts off once liquid reaches the pump end.
- Run-dry capable: the mechanical seal is oil-lubricated in its own chamber, so snore and dry-run conditions do not damage the seal faces.
- Continuous snore operation for sump and wellpoint duty — the pump re-primes each time the level recovers.
- Suction lift to roughly 28 ft of static lift; keep suction hose runs short and airtight for the fastest prime time.
- Priming times shorten with a flooded suction and lengthen on long, high-lift suction lines.
- Air-handling separation chamber keeps carryover out of the vacuum pump on entrained-air applications.
- Auto start/stop float control and the critically silenced enclosure make unattended overnight bypass duty practical.

Being straight with you
When to stay with Godwin®
If your specification names the OEM by brand with no substitution clause, or the unit is inside an OEM service contract, stay with the OEM for that unit — and use AMCO for the wear parts on the rest of the fleet.
