The B3 Battery drum pump is equipped with a brushless DC motor with an output of 320 watts. This powerful electric motor enables a delivery rate of up to 180 liters per minute and a delivery head of 11.8 meters of water column. "With 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," explains Takumi Nasu, Head of Development at Lutz Pumpen GmbH. "This leap in performance makes the new Generation Battery model particularly interesting for industrial applications with high delivery rates. Thanks to the absence of cables, which can quickly become a tripping hazard or cause a short circuit, the battery-operated drum pump is significantly safer and more flexible."

Pump up to 5,800 liters with one battery charge

Operating the B3 Battery is extremely simple. The user secures the tubular pumping unit in the container using an adapter with a screw cap. When the barrel pump is switched on, a high-performance propeller generates a flow channel at up to 10,000 revolutions per minute. The liquid flows through the pumping unit into a hose and can be dispensed manually using a nozzle. An optional flow meter ensures precision.

One battery charge is enough to empty a 200-liter drum 14 times - in around 15 minutes. At a lower speed, an IBC container with 1000 liters can be pumped out 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 on the market," says Nasu. "This is easy on employees' nerves and prevents fatigue."

Motor can be combined with various pumping units

In order to be able to use the B3 for pumping as many different liquid media as possible, Lutz Pumpen has opted for a modular design. The individual components - the 1.2 kg motor with removable battery, the pumping unit that can be screwed on via a handwheel, the hose and the dosing gun - can be combined with each other according to the modular principle.

The pump unit, for example, is manufactured in several versions. There are versions made from polypropylene (PP) for low-viscosity acids, sodium hydroxide and ammonia water, from polyvinylidene fluoride (PVDF) for concentrated alkalis and acids such as chloric acid and sulphuric acid, from aluminum for diesel, heating oil and hydraulic oil and from FDA-compliant stainless steel for liquids in the food industry. The maximum viscosity of the media may be 700 millipascal-seconds (mPas).

The pumping units are manufactured for use in canisters, drums or containers in the standard immersion depths of 500 mm, 700 mm, 1,000 mm and 1,200 mm. On customer request, Lutz Pumpen also produces special lengths between 300 mm and 3,000 mm for special containers and pump sumps. "We also offer the option of combining the modular battery motor with a progressive cavity pump for pumping highly viscous media. This is unique in the industry to date." It is also possible to combine the B3 Battery with hybrid mixing pumping units and patented residual emptying pumping units. This makes it possible to simultaneously mix liquids during pumping and empty drums down to the last tenth of a liter.

The B3 is the latest addition to the Battery generation. Variants B1 with a 70-watt motor for small quantities of up to 20 liters per minute and B2 with a 260-watt motor for medium-sized quantities of up to 65 liters per minute are also available.
