Guide to choosing the best pumps for the naval industry

In the naval industry, the efficiency and reliability of systems are critical to ensure the proper operation of ships. Among the essential components of these systems, pumps play a crucial role. In particular, high-pressure pumps are indispensable tools for a wide range of applications, including water treatment through reverse osmosis.

With this article, we at Hawk will give an overview of pumps applied to the naval industry, with a focus on their operation and requirements for choosing the best solutions.

The function of high-pressure pumps in reverse osmosis systems

The high-pressure pumps used in reverse osmosis systems have the basic task of providing the energy needed to push water through the system's semipermeable membranes. This process is essential to separate impurities, salts and contaminants from the water.

These technologies provide several functions and benefits:

• Generation of required pressure: reverse osmosis requires high pressure to overcome the natural osmotic pressure of salty or contaminated water. The required pressure varies depending on the salinity level.
• Uniform system supply: the pump ensures a constant and uniform flow of water to the membrane, optimizing the filtration process and preventing damage.
• Energy efficiency: modern-quality high-pressure pumps are designed to operate with maximum efficiency, reducing energy consumption.
• Membrane protection: maintaining the correct pressure is critical to prevent the membrane from being damaged or the system from not achieving the required level of purification.
• Corrosion resistance: pumps must be made of materials that are resistant to the corrosive agents found in seawater.

Because of their ability to operate under extreme conditions, piston pumps are an ideal solution to ensure the continued operation of reverse osmosis plants for the naval industry.

Factors to consider when choosing reverse osmosis pumps in the naval industry

Choosing the right pump for a reverse osmosis system is a technical decision that requires attention to several factors. Below, we review the main aspects to evaluate:

• Flow rate and pressure: It is essential that the pump be sized to provide the pressure and flow rate required by the system. Insufficient pressure compromises the efficiency of the process.
• Construction materials: marine pumps must resist corrosion caused by salt water. Materials such as stainless steel and nickel alloys are ideal.
• Ease of maintenance: at sea, time for maintenance is limited. Pumps should be designed to allow quick and easy servicing.

The best Hawk pumps for reverse osmosis in the naval industry

At Hawk, we offer a range of pumps and accessories for reverse osmosis applications in the naval industry to ensure pressure washing even through the use of salt water.

These pumps are made of corrosion-resistant materials such as AISI 316L stainless steel and Ecobrass brass. Ecobrass, in particular, is a special lead-free, sustainable copper-zinc alloy free of toxic additives, with an ability to resist mechanical deformation and fracture and superior corrosion resistance to conventional brass. As a result, it is ideal for many industrial settings, but especially for marine and sanitary environments.

Two models particularly stand out among the best Hawk pumps for the naval industry: the NHDP Chemical Series and the XLTI Chemical Series.

NHDP Chemical Series pumps operate at a maximum pressure of 200 bar and a water temperature of up to 65°C. The ECOBRASS pumphead offers a highly corrosion-resistant solution, particularly suitable for saltwater and aggressive fluid applications.

The XLTI Chemical Series pumps, on the other hand, can work at a maximum pressure of 150 bar and a water temperature of up to 65°C. Again, the series is suitable for use with seawater and chemical solvents.
