Responding to this development, Lutz Pumpen will present the B70H eccentric screw pump, which can be flexibly mounted on a transport trolley, and the battery-powered B3 Battery drum pump at the Pumps & Valves 2025 trade fair in Dortmund from 19 to 20 February 2025 (stand 5-L09 in hall 005).
The B70 series eccentric screw pumps are used in industrial applications to pump watery to highly viscous liquids with up to 100,000 mPas and media containing solids and shear-sensitive media. This can range from diesel and oil in the raw materials industry, to caramel and pasta products in the food industry and toothpaste and creams in the cosmetics industry.
“The B70 series pumps are characterised by a gentle and low-pulsation pumping action, which ensures that the structure and properties of sensitive food products, pharmaceuticals, biochemicals and polymers remain unchanged during transport”, explains Takumi Nasu, Head of Development at Lutz-Pumpen GmbH. The pumps work with an eccentric screw that rotates inside a static housing, thereby dividing the medium across individual chambers and conveying it along these chambers. This gentle pumping process only subjects the medium to a low mechanical load, which minimises the danger of shear stress.
A consistent flow rate without pressure peaks and dead times
The B70 series eccentric screw pumps also guarantee low levels of pulsation during operation. “The flow rate is constant and there are no sudden pressure peaks. This is advantageous not only for the stability of the transported medium but also minimises the dead time during which no liquid is pumped”, says Nasu. With a three-phase motor producing up to 900 revolutions per minute, the pumps achieve a flow rate of up to 120 l/min, a delivery head of up to 6 bar and are suitable for immersion depths between 500 mm and 2,500 mm. It is also possible to measure the flow rate indirectly via the speed of the rotor.
The B70H on a transport trolley
“Responding to the need of some users for a mobile solution that enables them to deploy the pump at several locations, we have launched the B70H for horizontal use on a transport trolley that can be easily pushed by one person. This solution is also suitable for confined spaces – for example in areas with low ceilings.”
Empty a 200-litre drum 14 times on a single battery charge: B3 takes on wired devices
Lutz Pumpen will present another mobile pump solution at Pumps & Valves 2025: the B3 Battery, a battery-powered drum pump suitable for mobile operation to empty liquids from drums, canisters and IBC containers. This new pump has a range of uses that include transferring acids, bases and solvents in the chemical industry, pumping liquids such as syrups, essences and cleaning agents in the food and beverage industry and pumping fertilisers or pesticides in water treatment and agricultural applications.
The B3 Battery
“In developing the B3 Battery, we have succeeded for the first time in making the performance of a battery-operated drum pump comparable to that of cable-connected versions,” says Andreas Rössler, Head of Sales at Lutz Pumpen GmbH. The pump is equipped with a brushless 320-watt DC motor offering a flow rate of up to 180 litres per minute and a delivery head of 11.8 metres of water. A single battery charge is enough to empty a 200-litre drum 14 times in just under 15 minutes. At a lower speed, for example, an IBC container with 1,000 litres can be pumped out 5.8 times in 51 minutes. The pump tube is available in different versions to convey as many chemicals as possible for water treatment applications. These include a polypropylene (PP) version for sodium hydroxide and a polyvinylidene fluoride (PVDF) version for chloric acid.
