Beurer BY-40 Electric Breast Pump

The Beurer BY-40 is a single-sided electric breast pump designed for breastfeeding mothers who want a comfortable, efficient, and easy-to-use option for expressing milk at home or on the go. Using vacuum technology to simulate the natural rhythm of a baby’s feeding, it provides a gentler, more natural pumping experience compared to fixed-intensity pumps.

The BY-40 offers 10 stimulation levels and 10 pumping levels — a total of 20 individually selectable settings — allowing each mother to find her optimal mode. The memory function stores the last-used setting, so you can resume your personalised combination every time without having to adjust from scratch. A clear, illuminated LCD display (7 cm) shows the current mode and a usage time counter, making it easy to monitor each session.

The silicone cushion (medium size) features a soft-touch surface that adapts gently to the shape of the breast for comfortable, skin-friendly application. Accessories are disinfectable for consistent hygiene. The pump includes adapters for Philips Avent and NUK bottles, and the compact design (16.80 × 10.00 × 5.30 cm, 700 g) makes it easy to handle and store. Operates on 4 × 1.5V AA batteries (included) or via the included mains adapter. Classified as a medical device under EU MDR 2017/745. Tested and recommended by 98% of midwives in independent testing. Backed by a 3-year Beurer guarantee.

Product Specifications

Usage Instructions

1. Wash hands thoroughly before assembling or using the breast pump.
2. Assemble the pump components as shown in the instruction manual. Ensure all connections are secure.
3. Insert batteries or connect the mains adapter.
4. Sit in a comfortable, upright position. Centre the silicone cushion over the nipple and areola, ensuring a gentle but complete seal against the breast.
5. Press the power button to switch on. The pump starts in stimulation mode automatically. The display shows the current level and a usage timer.
6. Use the stimulation level buttons to adjust up or down through levels 1–10 during the stimulation phase. When milk begins to flow, press the pumping mode button to switch to pumping mode.
7. Adjust the pumping level (1–10) to your comfort. Use the highest level that remains comfortable — never force to a painful level.
8. When finished, switch off and remove the cushion gently. Transfer or seal the bottle as needed.
9. Disassemble accessories and clean and disinfect as per care instructions.
10. The memory function will store your last-used levels for the next session.

Care Instructions

• Disassemble all accessories that came into contact with milk after each use.
• Wash the silicone cushion, tubing connector, bottle, and other milk-contact parts in warm soapy water. Rinse thoroughly.
• All accessories can be disinfected — by boiling, steam sterilisation, or disinfectant solution — as per the instruction manual guidance.
• Do not wash the motor unit or the display. Wipe the exterior with a soft, lightly damp cloth only.
• Do not submerge the motor unit in water.
• Allow all washed parts to air dry completely before reassembly and storage.
• Store in a clean, dry location away from direct sunlight.

Warnings and Precautions

• Do not use if nipple or breast skin is damaged, cracked, bleeding, or infected without prior medical guidance.
• Do not use the pump at a suction level that causes pain. Always work within your comfort range.
• Always consult a midwife or lactation consultant if you experience discomfort, reduced milk supply, or any difficulty with breastfeeding — a breast pump is a supplement to, not a replacement for, professional breastfeeding support.
• Do not allow milk to remain in the pump accessories between sessions without proper cleaning.
• Do not use accessories that appear damaged, cracked, or discoloured.
• This is a personal-use device — accessories should not be shared between users without complete sterilisation.
• Keep out of reach of children.
• Batteries can be dangerous if swallowed — keep separate from children at all times.
• If using the mains adapter, ensure the voltage matches your local supply before plugging in.
