Viton Valves Shurflo 94-390-05 Spare Part Series 8000
Modelo: 94-390-05- Sku: SHURREP012
- Vendor: Shurflo
Specifications
Product Description
The Viton Shurflo 94-390-05 Valve Kit is the original replacement part for diaphragm pumps of the 8000 series. Manufactured in Viton (FKM), a high-performance elastomer, they ensure a fast and tight seal with very low pressure loss even when working with demanding chemicals. If your equipment loses pressure at rest, takes time to prime, “hunts” with everything closed, or shows irregular flow during spraying, replacing the valves is the most effective intervention to restore performance and reliability.
Main Features
- OEM reference 94-390-05: direct compatibility with Shurflo 8000 series pump heads.
- Material Viton (FKM): excellent chemical resistance to fertilizers, herbicides, pesticides, oils, and common solvents.
- Factory seat and geometry: hermetic sealing and low pressure loss to maintain flow rate.
- Fast suction/discharge switching: less cavitation and quieter operation.
- Superior durability: thermal and mechanical stability for long working hours.
- Easy installation inside the pump head; no adjustments or machining required.
Advantages or Benefits
- Like-new performance: stable flow, fast priming, and sustained pressure.
- Protects the system: relieves the pressure switch and motor by eliminating internal leaks.
- Greater availability: reduces maintenance downtime and extends the life of the pump head.
- Chemical versatility: suitable for demanding spraying and cleaning mixtures.
- Cost-effective service: quick intervention with original replacement and immediate results.
Purpose or Applications
Especially recommended for agricultural spraying, pest control, professional cleaning, light industrial washing, and pressurized water services with Shurflo 8000 pumps, where chemicals and working temperatures require a high-specification elastomer.
