Spring-Loaded MOS Mechanism — Press-Down Motion  |  Manual Control Over Suction Speed  |  Safety Release Valve  |  Compatible with Pos-T-Vac Slip Cylinders & Bushings  |  No Batteries  |  By Timm Medical / Pos-T-Vac  |  Ships Discreetly

The Pos-T-Vac PTV Manual 3000 is a manual vacuum erection device built around the Motion of Sleeve (MOS) mechanism — a spring-loaded pump design that creates vacuum through a straight, vertical press-down motion on the pump head rather than the side-squeeze or hand-squeeze action used by most conventional manual VEDs. The spring provides consistent resistance with each press, so the pumping motion is controlled and repeatable; the user determines the speed and intensity of vacuum buildup by controlling the pace and depth of each downward press. Timm Medical designed the MOS mechanism specifically to make the pumping motion feel more natural and less mechanically disruptive, reducing the interruption to intimacy that many men report with conventional squeeze-pump designs. No batteries required. Safety release valve for immediate pressure release when needed. Compatible with Pos-T-Vac slip cylinders and bushings for a fitted, comfortable cylinder interface. Manual control throughout — the user determines every aspect of the vacuum creation process, from the first press to the release. By Timm Medical / Pos-T-Vac. Ships in plain, unmarked packaging.

The MOS Mechanism — How It Differs from Standard Manual Pumps

Most manual vacuum erection devices use one of two pump designs:

• Side-squeeze bulb — a rubber or silicone bulb squeezed in the palm; creates vacuum through compression; requires grip strength to squeeze and hold; the motion is lateral (side to side)
• Handle-squeeze / ratchet — a trigger or handle squeezed repeatedly; creates vacuum through repeated compression; requires finger and hand strength with each squeeze

The PTV Manual 3000's Motion of Sleeve (MOS) mechanism works differently:

• Press-down motion — the pump head is pressed downward in a straight, vertical motion against the spring resistance; the spring provides controlled, consistent feedback with each press
• Spring-loaded return — the spring automatically returns the pump head to its starting position after each press; no release motion required from the user
• Minimal grip requirement — the press-down motion requires much less sustained grip strength than squeeze-bulb or handle designs; appropriate for men with arthritis, limited hand strength, or conditions affecting grip
• User-controlled pacing — the speed of vacuum buildup is entirely determined by the user; pressing faster increases vacuum more quickly; pressing more slowly allows gradual, incremental buildup

The practical result is a pump motion that many men find more natural, less disruptive, and easier to control than conventional squeeze designs — particularly during use with a partner, where the vertical press-down motion is less visually conspicuous than a side-squeeze bulb.

Key Features

• Motion of Sleeve (MOS) spring-loaded mechanism — the defining feature of this pump; the spring-loaded press-down action provides consistent resistance, predictable vacuum buildup, and reduced grip strength requirements; the mechanism is built for durability and repeatability across regular long-term use
• Full user control over suction speed and intensity — because the vacuum is created manually through press pacing, the user has complete control at every point in the therapy session; suction can be increased gradually, held steady, or released immediately at any time; no motor to override or adjust settings on
• Safety release valve — immediate vacuum release at any point during therapy; the safety valve is accessible and simple to activate; meets Timm Medical's standard safety specifications for Pos-T-Vac VED systems
• No batteries — no charging, no replacement cost — the MOS is entirely mechanically operated; there are no batteries to charge or replace, no motor to maintain, and no electrical components that can fail; the pump is ready to use at any time without preparation
• Compatible with Pos-T-Vac slip cylinders and bushings — the Manual 3000 pump head works with the range of Pos-T-Vac slip cylinders and anatomical bushings; cylinder size and bushing selection can be tailored to the user's anatomy for optimal vacuum seal and comfort; compatible cylinder and bushing accessories are available separately if needed
• Designed for intimacy — Timm Medical specifically developed the MOS mechanism to minimize the disruption of the pumping process during intimate use; the vertical press-down motion is quieter, more compact, and less visually conspicuous than traditional squeeze-pump designs

Manual 3000 vs. Automatic 3000 — Choosing Between Them

Feature	PTV Manual 3000 (MOS) (This Model)	PTV Automatic 3000 (BOS-3)
Operation	Manual — spring-loaded press-down motion	Battery — push-button automatic suction
Batteries	None required	3 AA batteries (included)
Suction Control	Full manual — user controls speed and depth	Automatic — motor determines suction rate
Cylinder Connection	Slip fit	Patented twist-and-lock
Noise	Silent — no motor	Near-silent motor
Hand Strength Required	Minimal — spring-loaded press motion	Minimal — push-button operation
Best For	Full manual control; no batteries; intimate use; MOS motion preference	Automatic suction; fastest vacuum; longest battery life

Who This Is Best For

• Men who prefer manual control over vacuum therapy and want a more natural pumping motion than squeeze-bulb or handle-squeeze designs provide
• Men who want a battery-free VED with no charging or battery replacement
• Men with limited grip strength or arthritis who find conventional squeeze-pump handles difficult — the press-down spring mechanism requires significantly less grip effort than side-squeeze designs
• Men using vacuum therapy with a partner who want the least conspicuous pumping motion available in a manual device
• Post-prostatectomy rehabilitation — the Manual 3000's controlled, gradual vacuum buildup is appropriate for daily penile rehabilitation therapy; consult your urologist for timing and protocol guidance specific to your situation
• Men who cannot take oral ED medications due to cardiovascular conditions, drug interactions, or personal preference

FAQs

What does "MOS" stand for and how does the motion work?

MOS stands for Motion of Sleeve. The pump head is spring-loaded and activated by pressing it downward in a straight, vertical motion — the spring provides consistent resistance with each press and automatically returns the head to the starting position after each press. The user presses down repeatedly at whatever pace creates the desired vacuum buildup rate, then releases pressure using the safety valve when the erection is achieved. The motion is distinctly different from side-squeeze bulb pumps and repeated-squeeze trigger designs; many men find the vertical press motion more ergonomic and more natural-feeling than either of those alternatives.

Does the Manual 3000 require any batteries or charging?

No. The MOS mechanism is entirely spring-loaded and mechanical — there are no batteries, no charging, and no electrical components of any kind. The pump is ready to use at any time without any preparation.

Is this appropriate for post-prostatectomy rehabilitation?

Yes — the Manual 3000 is appropriate for daily penile rehabilitation therapy following prostatectomy. The spring-loaded mechanism allows gradual, user-controlled vacuum buildup, which many men find preferable during the sensitivity of early post-surgical recovery. Consult your urologist or pelvic health specialist for specific guidance on timing, frequency, and duration for your situation.

Do I need a prescription?

No. The PTV Manual 3000 is an over-the-counter device. Consult your physician before use if you have cardiovascular conditions, bleeding disorders, or are taking anticoagulant medications.

How discreet is shipping?

All orders ship in plain, unmarked outer packaging with no reference to the product category or website on the exterior.
