Can I use my Philips Avent Double Electric Breast Pump as a single pump? Updated on 2022-02-11 The Philips Avent Double Breast Pump can work as a single pump. Please see below guidance. Guidance: Simply connect only one tube and continue pumping as usual. Do not block the opening of the other tube in any way as this might lead to damage of the motor. The vacuum strength will not be compromised, even though the second tubing port is not covered.
