KRACHT gear pumps are used in marine technology to lubricate gearboxes and engines. The pumps can be electrically or mechanically driven and can be equipped with different valves. KRACHT’s gear lubrication pumps have outboard bearing for direct mounting on the gearbox and for absorbing radial forces. The pre-lubrication pumps have motors that are highly efficient over large speed ranges.

LEWA has developed the triplex diaphragm pump especially for processes with higher pressures. This pump series offers various diaphragm technologies, including the patented LEWA DPS Diaphragm Protection System. The newest addition to the triplex range is the G3E, the smallest triplex pump so far. The LEWA pumps can operate at high pressures, are hermetically sealed, dry-run safe and include built-in safety features like overpressure protection and smart monitoring. Their robust design allows for easy onboard maintenance, making them ideal for seagoing vessels.

The Nikkiso Non-Seal canned motor pump is a seal-less centrifugal pump that is suitable for leak-free pumping of extremely critical, dangerous or toxic liquids. They are well suited for alternative marine fuels such as ammonia. The delivery program consists of a number of series: the standard model, pumps for high temperatures with or without cooling, EN-ISO 2858 and self-priming pumps. They can be equipped with Nikkiso’s unique E-monitor, a LED display that indicates the condition of the bearings and the direction of pump rotation in real time.

The HMD magnetically coupled pumps do not have a mechanical shaft seal but are executed with a magnetic coupling, which means the pumps are hermetically closed. These metallic pumps are extremely suitable for pumping corrosive, aggressive, toxic and other liquids where leakage is very undesirable.
