Preparing a boat for launch is always a balance between the desire to be on the wave faster and the need to perform routine, but important procedures. Pumping cylinders And the bottom takes time and physical effort, especially if you're on the shore in the heat or the wind is interfering with the installation, and it's at those moments that special devices designed for inflatable boat owners come to the rescue.
Company Bravo It has established itself as one of the market leaders in water-motor accessories, offering reliable solutions for process automation. Electric pumpPowered by a 12-volt onboard network, the PVC is an ideal companion for fishermen and tourists using a car battery or separate traction battery to power the equipment.
In this article, we will discuss in detail why it is worth choosing the products of this brand, how to connect the device correctly and what nuances of operation will prolong the life of your equipment. compressor This will save you time and energy, which is better to devote to the fishing or rest on the water.
Benefits of using Bravo electric pumps
Use of use supercharger So unlike foot or hand models, the electric options allow you to completely free the hands of the operator, so you can control the pressure, straighten the hose or install other equipment while the cylinders are filled with air.
Model range Bravo The case is often made of durable plastic, resistant to ultraviolet light and salt water, which is critical for field use. shutdown when a given pressure is reached, which eliminates the risk of rupture of the seams due to pumping.
Always check the integrity of the sealing rubber bands on the adapters before the start of the season – this will prevent pressure loss and overheating of the pump engine.
An important aspect is the versatility of the connection: a standard lighter or plug for direct connection to the battery makes these pumps compatible with any boat that has a motor or an additional battery. Important for large boats from 3.5 meters in lengthwhere the volume of air pumped is significant.
- 🚀 High performance allows you to pump a medium-sized boat in 8-12 minutes without physical effort.
- 🛡️ The robust design of the body protects the internal mechanisms from splashes, sand and mechanical shocks.
- 🔌 The 12 Volt universal power supply is suitable for connecting to the car battery or the boat’s onboard network.
Technical specifications and working principle
The basis of any device Bravo It's a DC motor that's designed to run in the 10 to 14 volt range, and the current you use varies from model to model, and it's 10 to 20 Amps at maximum load, which means you need a battery that's good enough to run efficiently, or you might drop the voltage and you might lose performance.
The principle of operation is based on creating a vacuum at the entrance and pressurizing the outlet with the help of a rotating impeller or piston group (in two-stage models). Two-stage system The first stage quickly fills the volume of the cylinder with a large amount of air at low pressure, and the second stage achieves the required pressure (usually up to 200-250 mbar).
⚠️ Warning: Do not allow the engine to idle with the output hole closed for longer than 30 seconds, as this can lead to critical overheating and melting of internal parts.
To monitor the parameters, many models are equipped with built-in pressure gauges or the ability to install an external sensor, the accuracy of readings directly affects the rigidity of the inflated bottom and side.
Review of popular models of Bravo pumps
The product line includes several key series, each focused on nano-tasks. B 12 These are classic single-stage solutions for small and medium-sized boats, which are compact, lightweight and provide a decent flow rate.
More advanced versions, such as B 180 or B 200These are often equipped with two compression stages, which significantly reduces the time of preparing the vessel for the exit, and the two-mode operation switches automatically or mechanically, providing the optimal balance between flow rate and final pressure.
Comparative table of specifications will help to determine the choice of the appropriate modification for your boat:
| Model | Type | Max. pressure (mbar) | Productivity (l/min) | Weight (kg) |
|---|---|---|---|---|
| Bravo B-12 | Single-stage | 180 | 350 | 1.2 |
| Bravo B-180 | Two-stage | 250 | 480 / 180 | 1.8 |
| Bravo B-200 | Two-stage | 250 | 500 / 200 | 2.1 |
| Bravo B-12M | Mini. | 120 | 280 | 0.9 |
When choosing a particular model, you should pay attention not only to numbers, but also to the equipment. The presence of a carry-on bag, a set of adapters for different types of valves (Boston, Leafield, Bravo) makes it much easier to operate. sustainability framework on soft ground or deck.
Proper connection to 12B power supply
The quality of the connection directly affects the efficiency of work compressorThe standard plug in the lighter of the car is convenient, but has limitations on current. If the wiring in the car is old or the wire section in the socket of the lighter is small, it is possible to drop the voltage and heat the contacts. For powerful models, direct connection to the battery terminals is recommended.
Use wires with a cross section of at least 2.5 mm2 (preferably 4 mm2) to connect the pump to the battery. Long and thin wires create resistance, which leads to loss of power on the way to the engine. At the ends of the wires should be installed reliable clamps ("crocodiles") with copper contacts, ensuring tight pressing to the battery terminals.
☑️ Checking before connection
If you plan to use the pump often away from the car, it makes sense to purchase or assemble a separate pump. portableLithium-iron-phosphate (LiFePO4) batteries weighing about 2-3 kg do an excellent job of this, providing several cycles of full pumping of the boat without recharging.
It's important to keep polarity in mind when you're connected. Bravo They have a gyration protection, you don't have to risk electronics. Red wire always connects to plus (+), black wire to minus (-).
Instructions for operation and pumping of the boat
The process of preparing the boat for the outlet requires consistency. First spread the PVC product on a flat surface, clearing the bottom of sharp objects. Connect the hose to the pump by selecting the appropriate adapter for the valve of your boat. Make sure that the valve is in the closed position (if it is a valve of the type "Frog" or similar) before starting the air supply.
Turn on the pump and control the process. At the initial stage, the cylinders fill up quickly, but as the pressure increases, the speed may decrease, which is normal for piston and membrane systems. Control the temperature. If it gets too hot, let it cool for 5-10 minutes, especially in hot weather.
⚠️ Warning: Never leave a working pump unattended for a long time, especially in direct sunlight, as overheating can cause the device to fail.
Once the required pressure is reached (usually 0.2-0.25 atm for the side and up to 0.4-0.6 atm for the High Pressure inflatable floor), turn off the device. Quickly disconnect the hose and close the valve. Remember that in the sun the pressure inside the cylinders will rise, so do not pump the boat "to zero" in the cold air in the morning.
Nuances of winter operation
At temperatures below -5°C, the plastic of hoses and housings becomes brittle. Warm the pump in a warm room before use and try to minimize the time of operation in the cold by taking breaks for warming.
Maintenance and storage of equipment
Durability electric pump After each use, especially on water with salt or contaminated water, it is recommended to wipe the body with a wet cloth. Dust and sand, getting into the mechanism through the ventilation holes, can cause accelerated wear of rubbing parts.
Keep the device dry, in the original bag or box. It is not recommended to leave the pump in the trunk of the car in the winter or in the summer heat, as extreme temperatures adversely affect the plastic and lubrication of bearings. Periodically check the status of electrical contacts and if necessary, clean them from oxidation.
If you notice a decrease in performance or the appearance of foreign noise, do not try to disassemble the case yourself if the device is warranty. Often the problem is solved by replacing the filter element at the air inlet or lubricating the rolling parts with special compounds that do not destroy rubber.
Regular cleaning of the inlet filter and checking the tightness of the connections prolong the life of the pump by 2 times.
Frequently Asked Questions (FAQ)
Can a Bravo 12B pump be connected to a 220V network via an adapter?
Yes, it is possible, but you will need a special power supply (adapter) that converts 220V to 12V DC. It is important that the power of the adapter was sufficient, it must give a current of at least 15-20 Amps. Conventional car adapters 2-5 Amps will burn instantly or do not start the engine.
How long does the pump last from a fully charged 55Ah car battery?
With an average current consumption of 12-15 Amps, a healthy 55 Ah battery will allow you to make 3-4 full pumping cycles of the boat without critical discharge. However, it is not recommended to discharge the start battery below 50% to keep the car engine running.
Why does the pump hum, but the air pumps poorly?
The most likely cause is clogging of the inlet filter or leakage of air in the hose joints, which may also indicate wear on piston rings or membranes, check the integrity of the hose and the density of the adapters to the boat valves.
Will this pump be suitable for SUP inflatable boards?
Most models Bravo These are designed for pressures up to 200-250 mbar (0.2-0.25 atm), whereas SUP boards often require 15-20 PSI (about 1.0-1.4 atm). Boards require special two-stage high-pressure turbo pumps. A conventional Bravo outboard pump may not reach the required pressure or will do so extremely slowly.
