Because of being part of one of the most crucial operations on board we have infinite motivation to fully understand our customers’ expectations to develop and optimize the mechanical requirements of our pumps.
This starts with the three different industries our pumps are operating in: maritime, offshore and tank storage. The maritime industry has oil, product and chemical tankers in various sizes with the need of our pumps:
1. Inland Tankers and Barges
2. General Tankers
3. MR1 Tankers
4. MR2 Tankers
5. LR1 Tankers
6. LR2 Tankers
The offshore industry has FPSO and FSO’s with storage tanks that have to discharge the crude oil to shuttle tankers with our pumps. And the tank storage industry has storage tanks with floating roofs. These roofs are equipped with our deep well pump to prevent from floating raining water on these roofs.
All these industries have various circumstances for operation. Our deep well pumps are engineered due to understanding the technical requirements of the vessel based on types of cargoes, temperatures, capacities. And to understand the operation requirements of the owner based on; efficiency, environment and the people that have to operate the system. These topics have let us create a high-end product portfolio.
Our motive is optimum efficiency with the least maintenance interference. According to our engineers this can be achieved when eliminating or protecting the weak spots in the system. Mechanically the strength of the pump head, pipe stack, shaft and spline connections are key. Electrically the protection against resonance and oscillation is the focus. And last but not least, the people that operate the system from installation to discharge want to have a smooth experience.

success storyAll our pumps are; single stage centrifugal pumps. They are always designed with an ‘oil-lubricated’ drive shaft located in a separate supporting pipe. The deep well pumps have four main sections; electric motor, deck arrangement, pipe stack and pump head.
For the maritime industry we have maritime standard design and for the offshore industry our pumps are designed according to API-610.
The size and design of the pumps is depending on capacity, head. We have two types of design; eccentric and concentric. Our standard material is AISI 316L but due to different types of cargoes we are able supply in various materials. Since the driveshaft and shaft are not exposed to cargo we use 42CrMo4V material and for the driveshaft and 32CrNiMo6V for the shaft a very high grade steel. This design is perfect for this environment and required strength.
Over the years we have built on experience in various outstanding situations as:
- Winterization -60 °C / -76 °F
- ATEX
On our website we will inform you about our standard designs. If you want to know more about above mentioned topics please get in contact with marflex.
We have MarFlex service engineers located in the Netherlands, China and Japan. To be as close as possible to your vessel or platform we have valuable relationships with our service cooperation’s in the United States, Russia, Dubai and Singapore.
