The Koshin 007025801 is an Original Equipment Manufacturer (OEM) mechanical seal assembly featuring a 20mm internal diameter (Φ20). It is engineered primarily for Koshin's GL-Series high-performance gear pumps.

Key Specifications

• Brand: Koshin

• Part Number: 007025801

• Part Type: Mechanical Seal

• Size/Shaft Diameter: Φ 20 (20 mm)

• Compatibility: Designed for Koshin GL-Series gear pumps (which are commonly used for pumping high-viscosity fluids like oils, lubricants, and agricultural liquids).

Design & Features

• Premium Leak Protection: Acts as the primary rotary barrier on the drive shaft, preventing high-viscosity fluids and oils from leaking out of the pump casing during pressurized operation.

• Friction & Wear Resistant: Manufactured with heavy-duty seal faces built to withstand the constant rotational friction and thermal stress generated by industrial gear pumps.

• Exact Dimensional Tolerance: The precise 20mm factory sizing ensures perfect alignment on the pump shaft. Using a genuine OEM mechanical seal guarantees the correct spring tension and face pressure, preventing premature seal failure and protecting the pump's internal bearings from fluid contamination.
