Two Reasons to Order This
1. Pump Head Replacement
If your Pos-T-Vac twist cylinder is in good condition but the battery pump head has failed — motor no longer running, button unresponsive, safety valve damaged — replacing the pump head alone is significantly more economical than replacing the complete system. The BOS-2000-3 pump head fits directly onto your existing twist-lock cylinder. Many users report using the same cylinder for a decade or more with multiple pump head replacements.
2. Upgrade from 2-Cell to 3-Cell Power
If you currently have a BOS-2000-2 (2-cell) pump head and want the increased motor power of a 3-cell system — faster vacuum creation, higher maximum suction, longer battery life per set — the BOS-2000-3 installs directly onto your existing twist cylinder. The upgrade gives you 3-cell performance while keeping the cylinder, rings, and accessories you already have.
BOS-2000-3 vs. BOS-2000-2 — The Power Difference
| Feature | BOS-2000-3 (This) | BOS-2000-2 (2-Cell) |

| Connection | Twist-lock | Twist-lock |
| Safety Valves | Dual (internal + external) | Dual (internal + external) |
| Best For | Maximum power; 3-cell upgrade; demanding users; extended sessions | Standard reliable performance; budget replacement |
FAQs
Do batteries come included?
No — 3 AA batteries are required but not included with the standalone pump head. The complete BOS-3 system kit includes batteries; the replacement pump head does not.
Will this fit my existing Pos-T-Vac twist cylinder exactly?
Yes — the BOS-2000-3 uses the same twist-lock interface as all current Pos-T-Vac twist cylinders. It fits the standard twist cylinder, the large twist cylinder, and cylinders from BOS-2 and BOS-3 systems. Confirm your system uses a twist-lock (rotate-to-lock) connection before ordering — if your cylinder is a push-in slip connection, this head is not compatible.
Can I add a battery pump head to my Manual 3000 system?
Yes — the Manual 3000 (V113 MOS) uses a twist-lock cylinder, so the BOS-2000-3 battery pump head is compatible. You would have both the manual and battery heads available and could switch between them using the same cylinder — effectively converting your system into a dual-mode setup.
How do the dual safety valves work?
The internal safety valve automatically releases pressure if vacuum exceeds the maximum safe level — it activates without any user action. The external red-button valve allows the user to manually release vacuum pressure at any point during therapy. Both valves are required by FDA regulations on all Pos-T-Vac pump heads.
