A new generation of rotary lobe pumps performs bilge pumping and conveying tasks maintenance-free and in extremely limited space

Background

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. At the same time, the systems have to be robust, as manpower can hardly be switched to repairs at sea and interim port stops are to be avoided at all costs for reasons of time. So maximum demands are placed on safety-critical systems such as bilge pumps.  

 

Challenge

Compact, weight-reduced, robust and simple to use – the main requirements for pumps in ships. The pumps must also be as versatile as possible for universal use to keep down the cost of servicing and spare part provisioning.  

 

Solution

TORNADO® rotary lobe pumps have been performing the job reliably for years. NETZSCH is now offering additional advantages with the new generation, TORNADO® T2. The new drive concept and the more compact pump design make the system practically maintenance-free and reduce the required installation space to a minimum. The heart of the TORNADO® T2 is an oil-free synchronised gear with belt drive instead of a complex and space-eating timing gear. The new gear not only reduces the weight of the pump by at least 30 percent, the entire mechanism is also almost error-free and the range of spare parts is thankfully low. As the system is not lubricated, time-consuming lubricant filling and the risk of environmentally hazardous leakages are a thing of the past.

TORNADO® Industrial Rotary Lobe Pumps T2

The TORNADO® rotary lobe pump is a positive displacement pump. The pumping action is generated by the contra-rotation of two rotors within the pump chamber which are synchronised externally. The media enters the pump chamber through the inlet port and is carried around the chamber by the rotors to the outlet port where it is discharged.
