Description
4247 705 2001 – STIHL Pump Cover Genuine OEM Part for SG 20
The STIHL Pump Cover 4247 705 2001 is a genuine OEM replacement component designed for the SG 20 sprayer pump assembly. This pump cover protects internal pump components while helping maintain proper sealing, alignment, and structural integrity during spraying applications.
The pump cover plays an important role in shielding internal parts from debris, contamination, and external damage. Over time, covers may crack, warp, or become damaged due to impact, pressure stress, or chemical exposure. A damaged pump cover can lead to improper sealing, reduced pump efficiency, or internal component wear.
Replacing the pump cover with the correct genuine STIHL OEM part restores proper protection, pump stability, and reliable sprayer performance.
Manufactured to STIHL factory specifications, this OEM pump cover ensures precise fitment, durability, and long-term reliability under demanding agricultural and landscaping conditions.
