Frequently Asked Questions
What is the function of the piston rod in a spray pump?
+
The piston rod transmits the driving force from the pump motor to the fluid piston, creating the pressure needed to move coating materials through the spray system. It must maintain precise dimensions and surface finish to ensure proper seal performance and prevent fluid leakage while withstanding high cyclic loads and potential abrasive conditions.
Which specific Graco models use this piston rod?
+
This piston rod is designed for Graco Ultra 400, Ultra 500, EM380, EM390, and EM490 series spray pumps. These are professional-grade airless sprayers used by contractors for various painting and coating applications. Always verify compatibility with your specific equipment model before purchasing.
Is the Bedford version a true aftermarket replacement for Graco 183563?
+
Yes, the Bedford 57-1748 is a genuine aftermarket replacement engineered to match the original Graco 183563 specifications exactly. It features the same hardened steel construction, precise dimensions, surface finish, and performance characteristics as the OEM piston rod for reliable operation in demanding spray applications.
Should I replace other components when installing a new piston rod?
+
Yes, it's highly recommended to replace piston packings, seals, and other wear components when installing a new piston rod. This ensures optimal performance and prevents premature wear on the new rod. Using a complete repacking kit along with the piston rod provides the best results and longest service life for your pump assembly.
What causes piston rod wear and when should it be replaced?
+
Piston rod wear can be caused by abrasive materials, inadequate lubrication, corrosion, or normal cyclic fatigue. Replacement is recommended when you observe visible scoring, pitting, corrosion, or wear that affects seal performance. Even minor surface imperfections can lead to fluid leakage and reduced pump efficiency over time.
Can I install this piston rod myself or should I seek professional service?
+
Installation requires mechanical aptitude and knowledge of spray pump systems. If you're experienced with pump maintenance and have the proper tools, you can perform the replacement. However, if you're unfamiliar with pump disassembly or lack the necessary tools, it's recommended to seek professional service to ensure proper installation and avoid damage to the new component or pump assembly.
