Mazzoni MMD Solid Shaft Pump Water Seal Kit with Brass

The Mazzoni MMD Pump Water Seal Kit with Brass is a complete replacement seal assembly for Mazzoni MMD solid shaft pressure washer pumps. Designed for more comprehensive seal service, the kit includes high-pressure water seals and precision brass retainers to replace worn components and restore proper sealing and pressure performance.

While standard water seal service addresses the pump's replaceable seals, this kit includes the brass components associated with the seal assembly, making it the appropriate choice when those components are also worn, damaged, or being replaced during a more complete pump repair.

Proper sealing around the plungers is essential for containing water and allowing a high-pressure pump to develop and maintain operating pressure. Worn seal assemblies can result in water leakage, pressure loss, and declining pump performance.

When Should I Use the Seal Kit with Brass?

Choose the seal kit with brass when servicing the water seals and the brass retainers within the seal assembly also require replacement, or when performing a more complete seal-section repair.

This kit may be appropriate when addressing:

• Worn or leaking water seals
• Worn or damaged brass retainers
• Water leakage from the pump
• Loss of operating pressure associated with seal wear
• More extensive seal-section repairs
• MMD pump rebuilds where the complete seal assembly requires service

If the existing brass components remain serviceable, the standard Mazzoni MMD Water Seal Kit may be sufficient.

Complete Water Seal Repair Kit

Provides the high-pressure water seals and brass components needed for a more comprehensive repair of compatible Mazzoni MMD pump seal assemblies.

Includes Precision Brass Retainers

Unlike the standard seal kit, this configuration includes brass retainers for servicing worn or damaged components within the pump's seal assembly.

Helps Stop Water Leakage

Replaces worn sealing components that can allow water to escape around the pump plungers during operation.

Helps Restore Pressure Performance

Restoring proper sealing can help the pump develop and maintain operating pressure when worn seal assemblies are responsible for performance loss.

Designed for More Complete Pump Service

Ideal for MMD repairs where replacing the water seals alone does not address all worn components within the seal assembly.

Extends the Serviceability of the Pump

Allows worn seal assemblies to be repaired rather than requiring replacement of an otherwise serviceable pressure washer pump.
