Description

When you’re running spray equipment or chemical application systems, keeping your diaphragm pump properly sealed is critical for maintaining pressure and preventing chemical leaks. This service cap is designed to keep your AR Pumps diaphragm system running smoothly, whether you’re spraying herbicides in the field or running liquid fertilizer through your applicator. A loose or damaged cap can cause pressure drops, chemical leaks, and the kind of downtime you don’t need during spray season.

Precision-fit cap designed specifically for AR Pumps diaphragm systems
Durable construction that stands up to agricultural chemicals and field conditions

Built for Real Farm Work

This cap is engineered for AR Pumps medium pressure diaphragm pumps commonly used in sprayer applications across farming operations. These pumps handle everything from pre-emergence herbicides to post-emergence treatments, liquid fertilizers, and specialty crop applications where precise chemical delivery matters for both crop health and cost control.

Made to Last

Agricultural spray equipment takes a beating from chemical exposure, temperature swings, and constant vibration. This cap is built to handle the harsh environment of farm spraying operations, maintaining its seal and structural integrity season after season.

Installation Notes

Before installing the new cap, clean the threaded area thoroughly to remove any chemical residue or debris that could prevent proper sealing. Check that all mating surfaces are clean and undamaged for the best seal. The cap should thread on smoothly – if you feel resistance, stop and check for cross-threading or debris.
