Overview

The Aqualon 11623 – Liquid Displacer – Replaces OMAX 303294 is a core internal component of the cylinder assembly used in legacy OMAX and MAXIEM direct-drive pumps. It occupies the rear portion of the cylinder chamber, stabilizing internal volume and supporting consistent pressure transfer during each plunger stroke.

Purpose / Why It Matters

The liquid displacer ensures the correct internal geometry of the cylinder, helping maintain smooth pressure generation and efficient volumetric output. Wear, impact damage, or dimensional distortion can disrupt flow characteristics, accelerate seal wear, or reduce cylinder efficiency. Replacing the displacer restores proper internal spacing and helps maintain steady, predictable pump performance.

Compatibility

This part replaces OMAX 303294 and is compatible only with legacy OMAX direct-drive pumps and MAXIEM direct-drive pumps that specify this OEM number.
No EnduroMAX compatibility is implied.

When to Replace / Service Indicators

Replace the liquid displacer when:
• Internal scoring, wear marks, or deformation are visible
• Cylinder volumetric efficiency declines
• Seals are wearing unevenly or prematurely
• The wet end is opened for a major rebuild or internal component inspection

Common Uses

• Restoring proper internal geometry during cylinder rebuilds
• Improving pump efficiency and pressure consistency
• Replacing damaged displacers after seal failure or contamination events
• Completing major wet-end service on legacy OMAX/MAXIEM pumps

Why Choose Aqualon

The Aqualon 11623 matches the verified geometry and functional characteristics of OMAX 303294, ensuring proper internal spacing, predictable pressure behavior, and reliable long-term performance in legacy OMAX and MAXIEM direct-drive pump cylinder assemblies.
