Product Overview
This product is a Suction Spring Retainer/Retainer Cage for high-pressure plunger pumps/fracturing pumps. It is precisely forged from high-strength alloy steel and has undergone hardening and surface anti-corrosion treatment. The upper end face is marked with a clear model number steel stamp. The product adopts a large channel window design, which can effectively reduce the flow resistance of the medium. It is installed in the suction valve cavity of the pump head liquid cylinder, mainly used for precise axial positioning and fixation of the vane spring, preventing the spring from tilting, shifting or falling off under high-frequency and high-pressure impact, and ensuring the smooth opening and closing of the valve assembly.

Ordering Instructions
When placing an order, please provide the steel stamp part number engraved on the end face of the fixed seat (such as 01U... Series), or provide matching fracturing pump brands and models.
2. Please specify the installation location (suction end or discharge end) and the matching Verne specifications (such as API 4#, 5# or 6#) to ensure the correct guiding and positioning dimensions are matched.
