Maintenance-Free Pumping on Ships With Small Space Requirements

Rotary lobe pumps for bilge pumping and conveying tasks in tight spaces

Two things are severely limited on ships: Space and time. Compactness is particularly vital in the machine room, as each centimetre means a loss at the expense of valuable transport capacity. As a global specialist in complex fluid management, NETZSCH Pumps & Systems offers you pump solutions individually tailored to your shipbuilding needs.

In shipbuilding, for example, you benefit from using a TORNADO® T.Envi® rotary lobe pump for bilge and delivery tasks involving a wide range of media.

Highest safety and low space requirement for pumping on ships

Space and time are severely limited on ships worldwide. Every centimetre used for the engine room comes at the expense of transport space. Therefore, pumps on boats have to cope with a minimal amount of space. Nevertheless, the systems must be robust since hardly any workforce can be assigned for repairs during shipping, and intermediate stops in port are to be avoided for reasons of time and cost. The demands on safety-critical systems, particularly, such as bilge pumps for pumping out water that collects in the lower part of the ship's hull in case of a leak or even during regular operation, are incredibly high.

Universal ship pumps ensure the highest delivery volumes

Compact, weight-reduced, resistant, easy to handle and high-performance are the main demands on pumps in shipbuilding. The requirements for ship pumps are as varied as their areas of application. The most important places of use are the engine room, where fuel and oil are pumped into the engines, and numerous lubricant and hydraulic pumps are used for various aggregates. But water is also pumped for the operation and cooling of the machines and totals and draining of the hull. In addition to their universal applicability, pumps on ships sometimes have to pump high volumes.

Pumps on ships: How to save up to 30 percent weight

The compact and robust TORNADO® rotary lobe pumps from NETZSCH are particularly suitable for use in confined spaces, such as those found on ships. They have already proven their reliability in shipbuilding over decades. In addition to their robustness and small footprint, TORNADO® rotary lobe pumps offer numerous other advantages. The drive concept using synchronous belts and the compact pump design make the system practically maintenance-free and reduces the required installation space to a minimum. The heart of the TORNADO® is an oil-free synchronisation gear with a belt drive instead of a complex and voluminous synchronisation gear. This not only reduces the weight of the pump by at least 30 percent. On the other hand, the entire mechanism is hardly susceptible to faults, and the range of spare parts is minimal.

Due to the worldwide unique spatial separation between the pump and gear room, the pumps guarantee maximum operational safety on ships. In addition, there is no need for time-consuming lubricant changes and the risk of environmentally harmful leaks, as the pump does not need to be lubricated. The rotary lobe pumps are particularly robust and durable thanks to the material reversal. High service and repair costs and long downtimes of the ships are a matter of history with the TORNADO® T.Envi® rotary lobe pump.
