CliniEco Breast Pump & Replacement Parts — Flanges, Valves, Bottles

Which breast pump parts wear out first?

The valves and membranes go first, then the flanges and the bottles. The signs are the same in every case: suction that feels weaker than it did, milk drawn back toward the tubing, or a flange that no longer seals against the breast. Parts are consumables; the pump motor is the durable part of the system. A clinic that stocks spares shortens the gap between a failing valve and a parent giving up on pumping.

How do I choose the right flange size?

Measure the nipple diameter at the base and add roughly two to four millimetres to arrive at the tunnel size. A flange that is too small rubs; one that is too large pulls areola into the tunnel. Sizes commonly run from 21 mm to 30 mm, with 24 mm the size most pumps are supplied with. Fit is the most common reason pumping becomes uncomfortable.

How should parts be cleaned between sessions?

Rinse in cool water first so milk protein does not set, wash in hot soapy water with a brush kept for the purpose, and sanitise on the schedule the pump manufacturer states. Tubing is not meant to be washed — if milk reaches the tubing, the manufacturer's instruction is to replace it rather than to dry it out and carry on.

What should a clinic confirm about compatibility?

Parts are model-specific. Before a clinic stocks replacement flanges or valves, confirm the pump model and the part number that goes with it, because a valve that looks similar can change the suction profile. This page lists flanges, valves, diaphragms, bottles and storage bags as refillable accessories; the model match is what makes them work. Keep the model number on the parts bin label, not only in the purchasing system.
