Bathmate Hercules Hydro Max Original Water Pump

What this is

The Bathmate Hercules is a manual, water-filled pump cylinder for adult men, sold as a single unit. The carton carries the lowercase bathmate wordmark with the strapline "Just Add Water", and the model name is printed down the side of the barrel itself: Hercules. The barrel also carries a CE mark, and the carton carries a circular seal reading "2 Years Manufacturer Warranty". It is listed here under Penis Pumps.

There is no motor, no battery, no hose and no separate hand bulb. The Hercules is one moulded piece plus a valve fitting — that is the whole device.

How the unit is built

The Hercules is a single rigid, transparent barrel with a black concertina gaiter moulded onto its base. Looking at it from top to bottom, there are four parts worth knowing.

• The domed crown and valve fitting. The top of the barrel closes in a dome, and a small ridged fitting sits at the very apex with a black push button on top. This is the only control on the device.
• The barrel. A clear, one-piece moulded cylinder. Because it is transparent rather than opaque, the water inside and the seal at the base both stay visible while the unit is in use.
• The printed scale. A measuring strip runs most of the way up the barrel, printed with two parallel numeric columns in different units so the same reading can be taken either way. One column runs through the teens, the other through single figures.
• The bellows gaiter. Below the barrel sits a stack of roughly five or six thick black concertina folds, flaring out to a wide opening at the very bottom. This is the flexible part of the device, and there is no pump ball and no trigger anywhere on the unit.

Two red tabs are printed at either end of the scale strip. The upper one reads "Press To Release" and sits directly beneath the valve fitting. The lower one reads "Seal To Body" and sits where the barrel meets the gaiter. Between them, small print alongside the scale reads "Use The PID Code To Authenticate Your Hydropump", so each unit carries its own authentication code on the barrel.

Colourways

The gallery photographs this cylinder in three finishes: fully clear, translucent blue and translucent red. The gaiter, the crown fitting and the printed scale are identical across all three — only the tint of the barrel changes. The carton artwork also shows the three-colour line-up.

Specifications

Using it

The only operating text printed on this device is the pair of red tabs on the barrel: "Seal To Body" at the base and "Press To Release" at the crown. Those are the manufacturer's own words for what each end of the unit does, and they are all this device states about its own operation.

No method, no session length, no frequency and no pressure figure is printed on any surface photographed for this listing, and we are not going to supply those numbers ourselves. Any printed instructions supplied inside the carton are the correct source for that guidance — please read them before first use and follow them rather than anything you read online, this page included.

General handling notes that follow from the design rather than from any claim: the barrel is rigid plastic, so it is worth inspecting for cracks or crazing before each use; the gaiter is the part that flexes, so it is the part that will show wear first; and because the unit is designed to be filled with water, it should be emptied and left to dry fully before storage. Keep it out of direct sunlight and away from heat sources, which is ordinary practice for any moulded plastic item.

What this listing does not state

Some specifications are simply not printed on this product's packaging, and we would rather say so than fill the gaps. None of the following appears on the carton or the barrel: overall dimensions, internal chamber diameter, water capacity, weight, the polymer used for the barrel or the gaiter, a legible country of manufacture, a barcode, an address, a phone number or a website.

If you need any of those before ordering — particularly the internal diameter, which is the figure that determines fit — contact us and we will ask the supplier rather than estimate. The printed material inside the carton is also more complete than the outside of it.

Who it's for

This is a product for adults aged 18 and over who are specifically looking for a water-based pump cylinder rather than a powered or air-driven one, and who are comfortable with a device that has to be used in a filled bath or a running shower. That is not a small caveat: the Hercules cannot be used dry, so it suits someone who can build a few unhurried minutes in the bathroom into a routine.

Because it is entirely manual, there is nothing to charge and nothing to fail electrically, which some buyers prefer. The trade-off runs the other way too: everything depends on the seal you form and on your own effort at the gaiter, so it is less forgiving than an automatic unit and takes some practice to get comfortable with. If you would rather compare the alternatives first, the full range sits in Penis Pumps, and the wider department is Men.

Good to know

• Adults only. Sold for use by adults 18 and over.
• Speak to a professional first if any of this applies to you. If you have a circulatory or bleeding condition, take anticoagulant medication, have any implanted device, or have had surgery in the area, get advice from a licensed healthcare professional before using a suction device of any kind.
• Stop if it hurts. Discomfort, numbness, discolouration or pins and needles are all signals to release the pressure with the crown button and take the unit off. None of that is a normal part of use.
• Keep it as a single-person item. For hygiene reasons this is not something to share.
• Warranty. The carton seal states two years, manufacturer. Keep your order confirmation and the carton; brand warranty claims are normally handled by the manufacturer, and the PID code printed on the barrel is the unit's own reference.
• Keep out of reach of children.

Frequently Asked Questions

Is this a water pump or an air pump?

It is a water pump. The Bathmate Hercules is filled with water and worked by hand in a bath or shower, which is what the carton strapline "Just Add Water" refers to. It has no hose, no bulb and no motor, and it is not designed to be used dry.

What colour will I get?

The Hercules cylinder appears in this gallery in clear, blue and red, and this listing does not offer a colour choice at checkout. If a specific finish matters to you, message us before ordering and we will confirm what is in stock rather than guess.

How do I check that the unit is genuine?

Each Hercules barrel is printed with its own PID code, and the small print beside the measuring scale directs you to use that code to authenticate the pump. The code sits on the barrel next to the scale strip, so it is easy to find once the unit arrives.

What are the exact dimensions and internal diameter?

Those figures are not printed on any surface photographed for this listing, so we have deliberately not published them. The printed material supplied inside the carton carries the manufacturer's own specifications; if you need the internal diameter before you order, contact us and we will check with the supplier.

Does it need batteries or charging?

No. The Hercules is entirely hand operated, with no motor, no battery compartment and no charging port. The single black push button on the crown fitting is the only control on the device.

How is this order packaged and shipped?

Orders go out in plain outer packaging that names neither the contents nor Gear Isle, and the billing descriptor on your statement does not identify the product. The pump travels inside its own printed carton, which sits inside that plain outer.

How should I clean and store it?

Rinse the barrel and the gaiter with warm water after use, then empty the unit completely and let it air-dry before putting it away. Store it dry, out of direct sunlight and away from heat. Avoid abrasive cleaners on the barrel, since scratches on a clear moulding make it harder to inspect for damage.
