Breast pump suction level is measured in mmHg – milimetres of mercury – which is the standard unit of measuring vacuum pressure. When you’re buying a breast vacuum pump, you might see mmHg in the product listing. This number, generally in the range of 220 to 350, is the maximum suction level. Hospital grade pumps generally have maximum suction levels in the 300 range while personal grade pumps are generally in the 200 range. This doesn’t necessarily make a pump better or worse – it’s just symptomatic of hospital grade pumps having bigger, stronger motors since they are designed for more rigorous use. AJK mini vacuum pumps have been well used in the breast pump products for a long time. The different size and parameters of mini vacuum pumps are used for different suction level of breast pump.
