Jandy R0842500 VS FloPro 2.7 HP Diffuser Kit for VSFHP270DV2A
The Jandy R0842500 is an OEM diffuser kit designed for the Jandy VS FloPro 2.7 HP variable-speed pump model VSFHP270DV2A (DV2A series). The diffuser channels water exiting the impeller, helping the pump maintain efficient flow, stable priming, and smooth hydraulic performance.
What’s Included
- Diffuser with diffuser O-ring
- Mounting screws (2)
- Backplate O-ring
Key Details
- Manufacturer: Jandy
- Part Number: R0842500
- Product Type: Diffuser kit
- Primary Compatibility: Jandy VS FloPro DV2A pump series, commonly listed for VSFHP270DV2A
What This Part Does
- Directs and stabilizes water flow as it leaves the impeller to improve pump efficiency.
- Supports reliable priming and reduces turbulence that can contribute to noise or performance loss.
- Provides sealing at the diffuser/backplate interface using the included O-rings.
When to Replace the Diffuser
- Cracked diffuser body, broken vanes, or visible wear from debris contact
- Reduced flow or inconsistent prime after the basket/impeller area has been cleaned
- Unusual rattling or cavitation-like noise that persists after basic troubleshooting
- Recurring leaks at the wet-end seam where the backplate O-ring seals
Installation Notes
- Disconnect power at the breaker and relieve system pressure before opening the pump.
- Clean sealing surfaces and lightly lubricate O-rings with pool-safe silicone lubricant before reassembly.
- Tighten the diffuser screws evenly (alternate between screws) to keep the diffuser seated squarely.
- If the pump has shown any water intrusion or shaft-side leakage, replace the mechanical seal during the same service.
- Inspect the impeller and diffuser area for debris or damage before closing the wet end.

Maintenance Tip
Keep the pump basket clean and the lid O-ring lubricated to reduce suction strain and turbulence. Stable suction conditions help protect the diffuser and impeller from vibration, cavitation wear, and debris-related damage.
