Things to consider: Challenges for pumps in maritime applications

The challenges for pumps in maritime applications are as varied as their use cases. One of the most essential requirements for marine pumps is their resistance to salt water. As they are exposed to the aggressive influence of seawater, pumps in maritime applications must be made of corrosion-resistant materials such as stainless steel. This is the only way to ensure a long service life. In addition, marine pumps must withstand vibrations and shocks caused by the ship’s operation and the sea state. Robust designs and possibly vibration dampers or unique mounting systems are required to minimise these stresses’ effects and protect the pumps from damage. Another important aspect is the adaptability of the pumps to different operating conditions. On ships, fluid viscosities, pressures and temperatures can vary greatly. The pumps must cope with this variability and deliver reliable performance regardless of the operating conditions. Energy efficiency is also increasingly important. Energy consumption plays a crucial role in maritime applications regarding operating costs and environmental footprint. Therefore, pumps must be designed to be energy efficient and minimise energy consumption without compromising performance. In addition, marine pumps must be easy to maintain, as access to the pumps is often restricted due to limited space. They should be easy to maintain and repair without extensive disassembly work. Marine pumps must be carefully selected, installed and maintained to meet these challenges. This is the only way to ensure that they can withstand the specific demands of maritime operations and provide reliable performance over a long period.

Everything from a single source: NETZSCH pumps in all maritime applications

When selecting the right pump for your maritime application, the experts at NETZSCH provide the right support. As a global specialist in pumping complex liquids, NETZSCH offers four different pump technologies. In addition to the decades-proven technology of the NEMO®progressing cavity pump, the portfolio also includes TORNADO®rotary lobe pumps, NOTOS®multi screw pumps, PERIPRO®peristaltic pumps and grinding systems. The various product lines are ideally suited to cover all maritime requirements. They can be used universally as transfer and booster pumps in ships, shipyards, and offshore platforms. NETZSCH pumps protect everything in maritime applications, from fuel or wastewater transfer to loading, unloading and stripping. With NEMO® progressing cavity pumps, you can reliably convey highly viscous media such as oil sludge or wastewater, for example, due to the particular pumping principle. The more compact TORNADO® rotary lobe pumps, on the other hand, which offer an exceptionally high flow rate, are ideal for transferring various types of wastewater and for loading and unloading different media. You can supplement your pump with powerful grinders for grinding and separating large, hard objects, primarily when pumping wastewater. In this way, you can prevent damage to the pumps and pipelines.

cubic metres per hour capacity

Since space is limited on ships, the compact design combined with a high flow rate makes another pump type suitable for maritime applications. The flow rate of the TORNADO® rotary lobe pump is also independent of the viscosity of the medium. The TORNADO® T.Envi®, in particular, has been optimised for the requirements on the high seas. In addition to its compact dimensions, the T.Envi® is also easy to service and maintain. Thanks to the innovative design, you can reduce your costs for spare parts stocking and maintenance in the long term. In addition, the weight of the pump is reduced by at least 30 percent thanks to the oil-free synchronisation gear with belt drive, which saves you fuel in the long term.

To protect your pumps, we also offer grinding systems that grind or separate hard and heavy particles and thus prevent blockages or clogging due to solid matter. In addition, using grinding systems can prevent blockages of pipelines and other downstream equipment. This is another reason why they are often used on passenger ships.

In addition, the whole mechanism is less susceptible to faults, which means the range of spare parts can be kept very low.

Maritime applications: This is how to benefit from the use of NETZSCH pumps

If you want to pump solids-laden liquids such as wastewater, then the NEMO® progressing cavity pump is the right choice. Progressing cavity pumps have been used on countless passenger and container ships for decades to pump wastewater effectively. The pump design prevents backflow of the medium and, simultaneously, offers you a volume- and pressure-stable movement of the pumped material. This means that hardly any gravitational forces and pulsation occur. Since the medium's consistency and viscosity are irrelevant to the flow rate, NEMO® pumps are not only used for wastewater. On oil tankers and cargo ships, they pump oil residues, oil sludge, and on offshore platforms, even oil-gas-sand mixtures. The progressing cavity pumps enable you to achieve up to 400 m³/h capacities. Furthermore, they are also suitable for stripping and cleaning shipyard oil tanks.
