Universally deployable displacement pumps ensure reliable, smooth conveyance of a very wide range of media

To cover the full range of requirements for maritime use, NETZSCH Pumps & Systems has developed different product series, which can be universally deployed as transfer and booster aggregates on ships and wharves, as well as on offshore platforms. The NEMO^® progressing cavity, TORNADO^® rotary lobe, NOTOS® multi screw pumps together with NETZSCH macerators cover a really wide range of application areas – from fuel to sludge transport, through loading and unloading, even to stripping. Especially the TORNADO^® rotary lobe and the NOTOS^® multi screw pumps are ideal for the maritime sector because of their compact design whilst ensuring high flow rates.

NEMO^® progressing cavity pumps can cope with liquid media which contain solids, which means they are for instance frequently used on passenger and container ships to convey wastewater. The main advantage of the Nemo^® and it’s technology is the fact that the consistency, and especially the viscosity, of the medium are insignificant in terms of the product flow. This makes the Nemo® applicable in a very broad range.

TORNADO^® T2 pumps in particular are specifically suitable for the demands of use on the high seas: They are self-priming, valveless positive displacement pumps which can be optimally customized to meet the applications on board. In addition to their compact design, the minimum expenditure on spare part stock and the ease of maintenance is their major advantage. Long service or repair work are a thing of the past because of the special design with a large flange-to-flange cover plate and quick-fit non media-wetted taper locks of the shafts. It offers the possibility to exchange the rotors or other spare parts quickly without dismantling the pump from the pipework. The aggregate has an oil-free synchronised gear with belt drive. Time-consuming lubricant changes and the risk of environmentally hazardous leakages are not a problem anymore. The TORNADO^® rotary lobe pumps are suitable for oil sludge or wastewater and many other solid loaden media.

The NOTOS^® multi screw pumps excel in generating high pressures of up to 80 bar even in tight spaces and can cope with liquid temperatures of up to 300°C. A series of design innovations, in line with the principle of High Efficiency Unique Design (HEUD),  involving the spindle profile and the pump chamber, make them particularly efficient. The three model series 2NS, 3 NS and 4NS allow flow rates maxima from 200 m³/h (2NS) to a maximum of up to 1.500 m³/h (4NS). The NOTOS® pumps are ideal for transporting lubricant oil, fuel and chemicals.

Last but not least all of our pumps can also be supplemented by high-performance macerators for the grinding and separation of larger, harder objects, primarily when conveying wastewater.
