Products Description
Brass Guide Oil Ring for Agricultural Plunger Pump | Precision Radial Clearance Control
High-Density Self-Lubricating Metallic Interface Engineered for Reciprocating Shaft Alignment and Fluid-Film Stability.
Sprayer plunger 120A Air chamber
This high-precision brass guide oil ring is a core wearable component built for reciprocating plunger shafts of agricultural piston sprayer pumps. Machined from premium C36000 forged brass, it acts as a sacrificial wear interface that maintains precise annular clearance around the plunger shaft. It effectively avoids direct metal-to-metal friction and forms a steady hydrodynamic lubrication film for smooth pump operation.
Designed to offset lateral thrust generated during compression strokes, this guide ring corrects shaft eccentricity and prevents scratching and scoring on both plunger surfaces and cylinder bores. With excellent self-lubricating properties and tight tolerance construction, it delivers consistent low-friction performance during long-hour orchard and crop field spraying work. Universally compatible with 22-type, 26-type and 30-type pump plunger assemblies.
Technical Profiles & Materials
Self-Lubricating C36000 Metallurgy: The ring is fabricated from high-lead-content brass, inherently providing a low-friction bearing surface that minimizes plunger shaft wear without requiring external lubrication beyond the pumped fluid medium.
Precision-Honed Radial Interface: The internal bore undergoes a micro-finishing protocol, achieving a controlled diametral clearance that balances fluid-sealing requirements with the thermal expansion accommodation necessary during high-RPM operation.
Chemical-Inert Surface Stability: The brass substrate provides absolute immunity to galvanic corrosion and chemical attack from diverse organophosphate pesticides, acidic fertilizers, and alkaline cleaning agents commonly circulated through agricultural sprayer systems.

Products Application
Plunger Shaft Alignment & Protection
Serves as the core radial guiding part for the stuffing box of 22-type, 26-type and 30-type piston pump powerheads. It keeps the plunger perfectly centered during high-frequency reciprocating movement, eliminating eccentric shaft swing. This avoids premature packing wear and cylinder bore deformation, maintaining long-term pump sealing accuracy.
High-Pressure Orchard Sprayer Maintenance
An ideal wearable replacement part for seasonal overhaul of tractor and trailer-mounted orchard sprayer systems. Featuring a simple press-fit structure, it enables fast on-site replacement and quick pump recovery, effectively cutting downtime during peak farm pesticide spraying seasons.
Industrial Aftermarket Component Supply
A vital structural wear part for agricultural pump repair shops and equipment dealers. Built with standard dimensions and durable self-lubricating brass material, it easily restores factory-level plunger alignment and sealing performance for all types of mainstream agricultural sprayer pump fleets.

FAQ
Q: Are you an impartial industrial components dealer or a direct China water pump factors factory?
A:We are a direct, ISO9001-certified engineering water pump components manufacturing facility and precision fluid-control factor manufacture exporter primarily based in China. We function our personal cleanroom injection molding bays, computerized ultrasonic welding arrays, computerized hydraulic stress check stations, and clean-room packaging lines, passing direct-factory wholesale price financial savings straight to your element procurement margins.
Q: Can your manufacturing unit furnish full certification forms for food-contact or consuming water compliance?
A: Yes, absolutely. For food, beverage, or scientific applications, our manufacturing unit makes use of one hundred percent virgin, un-recycled polypropylene resins accompanied by means of fabric traceability certificates. We mechanically furnish B2B purchasers with complete FDA compliance documentation, NSF-grade compound declarations, and RoHS/REACH chemical protection screening sheets to make certain clean clearance thru worldwide customs.
Q: Do you provide customization picks for distinctly corrosive fluids like sturdy acids or ozone?
A: Yes, we are a thoroughly succesful OEM/ODM supplier. For aggressive chemical or ozone environments, we can improve the 12x26.5mm valve configuration in our factory: substituting the general PP housing with top class PVDF (Fluoropolymer) and changing any steel springs with Hastelloy or whole springless gravity-ball architecture, making sure final chemical resistance.
Q: How do we impervious a pattern batch to execute computerized lifecycle and burst-pressure testing?
A: We relatively inspire complete laboratory contrast earlier than logging mass grant agreements. We can ship a pattern lot of 5-10 gadgets of our inventory 12x26.5mm take a look at valves for assessment (setup costs and DHL/FedEx air freight apply). Once the factors pass by your inner lifecycle verification and a formal wholesale quantity manufacturing contract or container run is locked in, the sampling charges are a hundred percent credited returned to your industrial balance.
