High-Durability Aluminum Alloy | Genuine Koshin Quality

Product Specifications

Detailed Description

The Koshin 0115269 Flange Bracket is the backbone of your pump's housing assembly. Over time, original brackets can suffer from hairline fractures due to mechanical stress or corrosion from harsh water conditions.

This genuine OEM part is designed for a perfect-fit installation, eliminating the alignment issues common with third-party replicas. Its reinforced mounting points are vibration-resistant, protecting your pump’s internal seals and impeller from premature wear.

Interchangeability & Compatibility

This bracket is a direct "drop-in" replacement for the following models:

• Koshin SEH-80XK, SEH-80X: The industry-standard 3" gasoline-powered centrifugal pump.

• Koshin BFC-1: Specialized variants requiring the 80mm flange configuration.

• Cross-Reference: Also compatible with certain SE-80X configurations (Verify mounting bolt patterns before installation).

Expert Installation Advice

• Inspect the O-Ring: Whenever you replace the flange bracket, always inspect the mechanical seal and O-rings. If they show signs of flattening or cracking, replace them simultaneously to ensure a watertight seal.

• Torque Settings: Tighten mounting bolts in a star pattern. This ensures even pressure distribution across the flange face, preventing warping.

• Anti-Seize: Apply a small amount of anti-seize lubricant to the bolts. Since these pumps are often exposed to water, this prevents the bolts from rusting into the bracket for easier future maintenance.
