The diaphragm pump is emerging as a critical solution in the marine industry, which operates under some of the harshest conditions known to man. Ships and offshore platforms are tasked with handling a variety of fluids—bilge water, fuel oils, chemicals, sewage, and sludge—each presenting its own challenges. The environment is relentlessly aggressive: saltwater corrosion, confined spaces, flammable vapors, and fluctuating pressures are all part of the daily operational landscape.
The need for safe, reliable, and low-maintenance pumping solutions is paramount. Traditional electric pumps, while effective in certain controlled applications, often fall short when used in marine contexts. Problems such as inability to run dry, susceptibility to corrosion, and complex maintenance procedures make them less than ideal for vessels that require rugged, all-weather reliability.
At SEA ASIA 2025, OVELL engaged with various stakeholders—shipbuilders, engineers, maintenance managers, and procurement specialists—who shared real-world challenges that current pumping systems fail to meet. A recurring theme was the demand for a diaphragm pump that is versatile, corrosion-resistant, and maintenance-friendly—capable of performing across a wide range of marine applications.
One of the most significant issues shared by marine engineers is that many electric centrifugal pumps cannot operate without liquid in the system. If a pump runs dry, even for a few seconds, it can cause critical damage to seals and bearings. In unpredictable marine conditions, this presents a serious safety and operational risk.
Seawater and chemically aggressive fluids often wear down pump components quickly. For ships operating in remote areas or for long durations, frequent maintenance becomes impractical and expensive. Replacing seals, impellers, and motors not only increases costs but also affects voyage schedules.
Marine vessels are notorious for having compact engine rooms and narrow compartments. Conventional pump systems with large footprints or complex piping arrangements are difficult to install and maintain onboard.
Ships often deal with sludge, emulsified liquids, and mixtures containing solids. Many standard pumps are unable to cope with such compositions, leading to frequent clogging or inefficient transfer. Handling flammable or chemically aggressive substances adds another layer of complexity that many traditional systems are ill-equipped to manage.
OVELL has developed a range of Air-Operated Double Diaphragm (AODD) pumps that address the above challenges head-on. These pumps were prominently showcased at SEA ASIA 2025, sparking deep interest among marine professionals.
One of the flagship models presented was the OVELL A30SA, constructed from marine-grade stainless steel and equipped with a PTFE diaphragm. This configuration offers several marine-specific advantages:
OVELL’s diaphragm pumps were designed with versatility in mind. Here’s how they addressed specific issues shared by SEA ASIA attendees:
During SEA ASIA 2025, OVELL received encouraging feedback from existing clients and new visitors who had implemented their AODD systems. A particularly compelling case came from a coastal cargo vessel operator in Southeast Asia, who had replaced three of their electric centrifugal pumps with OVELL diaphragm units for bilge and chemical transfer operations.
We were constantly battling pump failures due to dry running and chemical corrosion. Since switching to OVELL’s diaphragm pumps, our maintenance team finally has peace of mind. These pumps just work—no leaks, no hassle.
The marine industry demands equipment that is tough, reliable, and built for the unexpected. From tankers to tugboats, and offshore platforms to ferries, fluid handling systems must endure saltwater exposure, fluid variability, and tight spatial constraints—challenges that traditional pump systems often fail to meet.
OVELL’s air-operated diaphragm pumps are purpose-built to fill this gap. Their unique combination of dry-run protection, chemical resistance, and maintenance simplicity makes them a logical choice for modern marine vessels looking to reduce downtime and increase safety.
OVELL is committed to continued innovation in the marine sector. In the coming months, the company plans to introduce smart monitoring features such as flow sensors, remote pressure gauges, and predictive maintenance alerts compatible with vessel management systems.
Whether you're a shipowner, fleet manager, or marine engineer, OVELL invites you to explore tailored pump solutions that meet the unique needs of your vessel. Our team of technical experts is on standby to help you:

A diaphragm pump is ideal for marine vessels due to its ability to self-prime, handle corrosive and viscous fluids, and run dry without damage. Its air-operated mechanism makes it reliable in spaces with limited electrical infrastructure.
Yes, especially when equipped with PTFE or stainless-steel components, diaphragm pumps are resistant to corrosive seawater and a wide range of chemicals commonly used on ships.
Unlike centrifugal pumps, diaphragm pumps can handle dry-running conditions, slurries, and high-viscosity fluids. They also require less maintenance and can operate without a continuous electrical supply.
Absolutely. Diaphragm pumps have few moving parts and no dynamic seals, making them easy to maintain, repair, or rebuild with basic tools—ideal for marine crews.
Yes. Air-operated diaphragm pumps don’t use electric motors, reducing the risk of ignition in explosive atmospheres—making them safe for fuel transfer and chemical handling on ships.
