Description

The 10001-01256 Seal Kit is a comprehensive maintenance set designed for the high-pressure and low-pressure water seals of General Pump FW2 Series triplex pumps. This kit is essential for restoring pump pressure and stopping leaks from the manifold head.

Kit Specifications

• Piston Diameter: 18mm

• Series Compatibility: FW2 Series (e.g., FW2-3030S, FW2-3530S)

• Components Included: Complete set of high-pressure packings and low-pressure seals for all three cylinders.

Kit Contents

Typically, this kit includes the following components (3 of each for a full pump service):

1. High-Pressure V-Sleeves: The primary seals responsible for containing the extreme pressure during the stroke.

2. Low-Pressure Seals: Located behind the high-pressure seals to prevent water from entering the crankcase.

3. Intermediate Rings / Restuctors: Support rings that hold the seals in the correct orientation.

Key Features

• Custom-Fit Engineering: Specifically sized for 18mm plungers, ensuring a watertight seal that reduces friction and prevents “pressure drop.”

• High-Grade Elastomers: Manufactured from specialized rubber compounds designed to withstand high temperatures and chemical exposure from detergents.

• Full Service Set: Provides enough components to rebuild all three plungers of the pump, ensuring uniform performance across the entire manifold.

Signs You Need This Kit

• Loss of Pressure: If your 3000+ PSI pump is struggling to reach rated pressure.

• Water Leaking: Visible dripping between the pump manifold (brass head) and the crankcase.

• Pulsation: Uneven vibrations in the high-pressure hose, often caused by one cylinder failing to seal.

• Milky Oil: Water bypassing the low-pressure seals and contaminating the pump oil.

Maintenance Tip: Always inspect your ceramic plungers while the seals are removed. If the 18mm plungers have deep scores, cracks, or a “water line” etched into them, new seals will fail prematurely. Replace damaged plungers alongside this kit for a long-lasting repair.
