ARO 635040 Stop Kit for NM2318B Piston Pumps
Stop kit called out in the parts lists of the ARO NM2318B-13-L43 and NM2318B-13-C43 piston pumps.
ARO 635040 is the stop kit listed for two NM2318B-13 piston pump models. Match the suffix on your nameplate, L43 or C43, before you order.
The ARO 635040 Stop Kit is a service kit for the NM2318B-13 family of ARO piston pumps. Our product data names it only as a stop kit and does not itemize the pieces inside, so lay it next to the exploded view in your pump manual before teardown.
The two pumps that call for 635040 share the NM2318B-13 base model and differ only in the last three characters. Read the complete model string from the pump nameplate and compare it with the list below.
When to Use This Kit
- Your NM2318B pump is opened up for a planned rebuild and the stop hardware is due for renewal.
- Inspection turns up stop components that are cracked, deformed or no longer seat properly.
- You want a spare on the shelf so the pump is not held up waiting on parts at the next shutdown.
