Material:
Carbon Steel,Alloy Steel

The Barrel in a piston pump is a cylindrical chamber where the reciprocating piston moves back and forth. It provides a sealed space for fluid or gas displacement. It creates a suction to draw in fluid or gas, compresses it, and then pushes it out through an outlet. The piston's movement creates a cycle of suction, compression, discharge, and return strokes to continuously pump the fluid or gas.

Attributes:
• Made up of Carbon Steel and Alloy Steel.
• Withstands pressure and forces.
• Manufactured with precise dimensions for optimal performance.
• Provides a tight seal to minimize leakage.

Application:
The Barrel in a piston pump creates a sealed chamber for fluid displacement and guides the piston's reciprocating motion.
