Manual Bilge Hand Pump – Plastic for Boats (Small & Large)

This manual bilge pump is designed to be simple, reliable, and always ready to go when you need to quickly remove unwanted water from your boat. Whether it’s rainwater, waves splashing aboard, or a minor leak, a hand pump is a sure solution that doesn’t rely on electricity – it works whenever you need it, as long as you have the strength to pump.

We offer the pump in two sizes to meet different needs:

• Small (~40 cm): Ideal for kayaks, canoes, and very small boats. This compact version is lightweight and can be operated with one hand. It can be stored under a kayak deck bungee or in a small hatch. Despite its smaller size, it effectively draws water – perfect for removing puddles accumulated from paddling or rain.
• Large (~50 cm): Suitable for sailboats, fishing boats, and larger motorboats. The longer length means more water per stroke, which saves time when you have a bigger volume to pump out. This model often comes with a long hose to help direct the discharge well overboard so the water doesn’t splash back in.

Features and Benefits:

• All-Plastic (Non-Corrosive): In a marine environment, metal parts can rust and seize – that’s why this pump is made from resilient plastic that won’t corrode. You can leave it on your boat with no worries about saltwater damage. The plunger and cylinder are precisely fitted for optimal seal and longevity.
• Simple Plunger Action: The pump works by pulling and pushing the handle, which creates vacuum and suction to draw water up. Double-action: some models pump on both the pull and push strokes – if applicable, that greatly increases output. Even with single-action, the pump removes water quickly thanks to its wide diameter.
• Safety & Readiness: A hand pump is a key piece of safety gear on board. If your electric bilge pump fails or you don’t have one, this pump can prevent a potentially dangerous flooding situation. Many boaters keep it as a backup even on boats with electrical pumps. Its compact size means you can mount it with clips in the bilge or under a gunwale for easy access in an emergency.
• Easy Maintenance: After use, just rinse it with fresh water (especially if used in saltwater). There are no complex mechanisms – just make sure the plunger’s O-ring or seal is free of sand and grime for optimum performance next time. If needed, apply a bit of silicone grease on the seal for smoother operation.
• Versatile Use: Beyond dewatering boats, the pump can be used for other tasks – such as draining a tent after rain, emptying an aquarium or small pool, or even emergency fluid transfer between containers.

Recommended Use: Place the pump’s intake (bottom of the cylinder) at the lowest point in the boat where water collects (bilge or sump). Ensure the small filter isn’t clogged. Start pumping vigorously – water will start shooting out of the hose or top outlet. Aim it overboard or into a bucket. The small model suits boats up to about 4-5 meters where space is limited. The large model will clear water faster in boats ~5-7+ meters or situations with more flooding.

In the end, a manual plastic pump is one of those tools you hope you won’t need often, but when you do, it can save your boat (and your day). Lightweight, durable, and effective – our hand pumps will help you keep your vessel dry and safe.
