Frequently Asked Questions

This is the bare bellows pump assembly only — it does not include guns, air controls, hoses, or accessories. Those are sold separately or as part of complete sprayer packages.

It is compatible with Merkur Bellows 25:1 SMT‑style systems listed above. Check your sprayer model number for exact fitment before ordering.

No — DataTrak compatibility is provided for optional monitoring/control, but the pump will still function without a DataTrak system installed.
