Belmikal 20mm Flange for Spectra S2/S1, 9 Plus, Motif Luna, Ameda MYA – Replacement Pump Parts

Overview

Belmikal 20mm flange set offers a practical, non-original replacement option for a range of popular breast pumps. Each package includes two 20mm flanges designed for a comfortable fit and steady pumping sessions, keeping compatibility in mind so you can adapt your setup quickly.

What’s in the box

• Contents: 2pc 20mm flanges

These flanges are suited for mothers with a nipple diameter after pumping of roughly 17–19 mm, which helps create a reliable seal without crowding or excessive stretch during use.

Model compatibility and performance

These are not original Spectra or Motif Luna/MYA parts, but they’re designed to work with a broad set of Spectra pump components and accessories. They deliver a comparable suction feel to OEM parts and support connections with valves, backflow protectors, and bottles.

• Compatible with Spectra S2, S1, Spectra Synergy Gold, Spectra 9 Plus, Motif Luna, Ameda MYA, Cimilre and other brands with 20mm flange standards
• Supports use with wide-mouth bottles from Spectra and Avent, as well as many other wide-mouth designs

Size range and materials

Choose from a broad size range to match comfort and fit: 13mm through 30mm in 1mm increments. All flanges are BPA-free and designed for safe, repeated use across daily pumping routines.

Care and sanitization

Cleaning is straightforward: rinse after each use and sanitize by steam, boiling water, or microwave steam bags. The durable yet flexible plastic is built to withstand regular cleaning while maintaining a comfortable touch against the skin.

Practical notes for daily use

For parents juggling feeding schedules, travel, and late-night sessions, a reliable flange can contribute to a steadier pumping rhythm and smoother bottle prep when needed. Actual results will depend on fit, pump model, and pumping patterns, but a well-matched flange may help conserve time and reduce frustration during busy days.

Fit tips and real-life scenarios

Start with a size close to your post-pump diameter, inspect for a gentle seal, and avoid over-tightening. A spare 20mm flange can be handy during travel or busy mornings to minimize downtime between sessions. The combination of two flanges in the set offers versatility for rotating use.

• Pro tip: try 17–19 mm as a starting point for many users after pumping
• Keep a clean, sanitized flange system for each session
• Store in a dry, cool place to preserve plastic integrity
