How to Read Aryung Coolant Pump Model Numbers
If you're replacing an Aryung (A-Ryung) coolant pump, the nameplate model number gets you most of the way there. It tells you the motor size, the pump family and, on many models, the immersion depth or head.
The basic pattern
Most numbers read in the same order: ACP, then motor output in watts, then pump type, then a suffix.
| Example | Motor | Type | Suffix means |
|---|---|---|---|
| ACP-400F | 400 W | F, immersion | None |
| ACP-400HF18 | 400 W | HF, higher lift immersion | 18 = 180 mm immersion depth |
| ACP-1100MF | 1100 W | MF, multistage | None |
| ACP-900HMFS 45 | 900 W | HMFS, multistage high head | 45 = delivery head class |
| ACP-4000HMFD 200V | 4000 W | HMFD, multistage very high head | 200 = delivery head class, V = vertical |
| ACP-4000HMFD 200H | 4000 W | HMFD | H = horizontal |
Letters you may also see
- S on MF or HF models: a variant of that series, so MF and MFS are not automatically interchangeable. Check immersion depth.
- 2/2: 200/220 V winding.
- F at the end of an MF number: flange outlet. No mark means a screw type.
Head changes with frequency
The number on an HMFS or HMFD model usually matches the 60 Hz head. The ACP-1800HMFS 70 is rated at 55 m at 50 Hz and 70 m at 60 Hz. US power is 60 Hz, but imported machines sometimes carry pumps wired for other voltages, so read the plate.
Also written as
The same pump can appear with or without hyphens and spaces: ACP-1100MF, ACP1100MF and ACP 1100MF are one model. Some suppliers also add a phase or voltage code. If a number you've been given doesn't match our listing, send it to us and we'll check it.
What to send us
Send a photo of the nameplate, the voltage and the machine model. We work directly with Aryung and can confirm the match. Browse Aryung coolant pumps or call 847-466-5459.
