Description
When your sprayer pump starts losing prime or isn’t pulling solution like it should, the problem often comes down to the inlet assembly. This critical component connects your tank to the pump, making sure liquid flows smoothly without air leaks that kill performance. A worn or cracked inlet assembly means your spray pressure drops right when you need it most.
What You’re Getting
- Complete sub-assembly that replaces worn inlet components in one go
- Proper sealing to keep air out and maintain consistent pump prime
- Durable construction that handles chemicals and temperature swings
- Direct replacement for part number 5275155
Built for Real Farm Work
This inlet assembly works with Fimco’s popular diaphragm pumps found on sprayers across farms and ranches. Whether you’re applying herbicide to crop ground, spraying pastures, or washing equipment, these pumps see constant use during spray season. The inlet assembly keeps everything flowing properly so you can focus on coverage instead of pump troubles.
Made to Last
Sprayer parts deal with harsh chemicals, weather extremes, and constant vibration. This replacement assembly is built to handle that environment, maintaining its seal and structural integrity through seasons of hard use. Quality materials resist chemical degradation and cracking that leads to air leaks.
Good to Know
Installation typically involves disconnecting the suction line, removing the old assembly, and installing the new one with fresh thread sealant. Check your suction hose and clamps while you’ve got things apart – a small air leak anywhere in the system will cause the same symptoms as a bad inlet assembly.
