New mobile drum pump

The new B3 Battery from Lutz Pumpen enables safe, mobile working with aggressive liquids, without compromising on pumping performance compared to cable-connected versions. This battery-operated drum pump, quieter than a vacuum cleaner, will be showcased from 10-14 June at Achema, a trade fair for the process industry.

Equipped with a brushless DC motor, the B3 Battery-powered drum pump delivers 320 watts of power. This robust electric motor achieves a delivery rate of up to 180 litres per minute and a delivery head of 11.8 metres water column.

“In developing the new 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,” said Takumi Nasu, Head of Development at Lutz Pumpen. “This leap in performance makes the new model of the battery product range especially interesting for industrial applications requiring high delivery rates. The absence of a cable – which can quickly constitute a tripping hazard or cause a short circuit – makes the battery-operated drum pump significantly safer and more flexible.”

Pump up to 5,800 litres on a single battery charge, more quietly than a vacuum cleaner

The B3 Battery is straightforward to operate. The user secures the tubular pump tube in the container with an adapter and screw cap. Activating the drum pump starts a high-performance propeller, generating a flow channel with up to 10,000 revolutions per minute. The liquid flows through the pump tube into a hose and can be dosed manually via a nozzle. An optional flow meter ensures precision.

One battery charge is sufficient to empty a 200-litre drum 14 times in around 15 minutes. At a lower speed, a 1000-litre IBC container can be emptied 5.8 times in just under 51 minutes. “With a noise level of just 70 dB (A), lower than that of a vacuum cleaner, the B3 Battery is significantly quieter than many electrically powered pumps currently available on the market,” added Nasu. “This is easy on employees' nerves and prevents fatigue.”

Configured like Lego: Motors can be combined with various pump tubes

Lutz Pumpen chose a modular design for the B3 to enable it to pump a wide range of liquid media. This modularity allows for the combination of various individual components: a 1.2 kg motor with removable battery, a pump tube that can be screwed on via a handwheel, a hose, and a dosing gun.

The pump tube is available in several versions. While polypropylene (PP) models are suitable for low-viscosity acids, sodium hydroxide, and ammonia water, polyvinylidene fluoride (PVDF) versions are used with concentrated alkali solutions and acids such as chloric and sulphuric acid. Aluminium models are intended for use with diesel, heating oil, and hydraulic oil, while our FDA-compliant stainless steel model is used in the food industry. The maximum viscosity of the pumped media is 700 millipascal-seconds (mPas).

The pump tubes are manufactured for use in canisters, drums, or containers in standard immersion depths of 500 mm, 700 mm, 1000 mm, and 1200 mm. On customer request, Lutz Pumpen also produces lengths between 300 mm and 3,000 mm for special containers and pump sumps.

“We also provide the option of combining the modular battery motor with an eccentric screw pump for the pumping of highly viscous media. This is currently unique in the industry.” The B3 Battery can also be paired with hybrid mixing-pumping tubes and patented residual emptying pump tubes, enabling simultaneous mixing of liquids during pumping and emptying of drums down to the last tenth of a litre.

The B3 is the latest addition to the battery product range, which also includes the B1 model with a 70-watt motor for small quantities of up to 20 litres per minute, and the B2 with a 260-watt motor for medium-sized quantities of up to 65 litres per minute.
