Bilge Pumping and Conveying Tasks in Shipbuilding Industry:

TORNADO® Rotary Lobe Pumps Provide Maintenance-Free Conveying in Confined Spaces

Look behind the scenes

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 accepted

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.  

Excellently solved

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.

Medium: Bilge
Throughput volume: up to 1000 m³/h
Pressure: 8 bar


TORNADO® T2 Industrial Rotary Lobe Pumps

The TORNADO® T2 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.

M-Ovas® Grinding System

NETZSCH M-Ovas® grinding systems can be used wherever it is essential that solid matter in fluids be broken down reliably to ensure the prevention of pipe clogging and damage to downstream equipment.

NEMO® C.Pro Dosing Pump

The NEMO® N-Ipos CY C.Pro dosing pump is a fully synthetic pump for the precise dosing of a great variety of chemicals in environmental technology and the chemical industry. Its synthetic construction makes it perfectly suited for the gentle and low-pulsation conveyance and dosing of aggressive or non-aggressive chemicals.

NEMO® Pump BY

NEMO® BY progressing cavity pumps can be used in any area of industry where a great variety of different substances must be pumped or very precisely dosed.
