Decoding the PHC3 Wet End
In the PHC3 code, P identifies the glass-filled polypropylene head, H identifies CSPE/Hypalon seats and O-rings, C identifies ceramic valve balls and 3 identifies the 1/2-inch OD tubing connection. The leading K5 marks a KOPkit for Size 5 heads.
How to Find the Right KOPkit for Your Pump
The KOPkit number is stamped on the PULSAtron nameplate and printed on the pump specification data sheet. From the model number, read the fourth character for head size and characters seven through ten for the wet-end code. A model in the format XXX5XX-PHC3-XXX takes the K5PHC3 kit.
CSPE/Hypalon Seats and O-Rings
Hypalon (CSPE) elastomer seals are the key difference between PHC3 and PTFE-sealed PTC3 configurations. Seal material should be matched to the original pump and checked against the chemical being metered.
Glass-Filled Polypropylene Head
The FPP pump head distinguishes K5PHC3 from the PVC-headed K5VHC3. Both use Hypalon seals, ceramic valve balls and 1/2-inch OD tubing, so the head material is the deciding factor when ordering.
K5PHC3 Versus K5PTC3
K5PHC3 and K5PTC3 share the Size 5 FPP head, ceramic valves and 1/2-inch OD tubing. K5PHC3 uses Hypalon seals while K5PTC3 uses PTFE seals. Match the original wet-end code rather than substituting.
Typical KOPkit Components
Pulsafeeder describes typical solenoid diaphragm KOPkits as including the pump head, diaphragm, check-valve assemblies and associated maintenance components. Exact contents depend on the supplied kit revision.
Maintenance Checklist
- Confirm the Size 5 head designation.
- Verify the PHC3 wet-end code on the nameplate.
- Check FPP, Hypalon and ceramic material requirements.
- Inspect the tubing and valve components.
- Depressurize and isolate the pump before service.
Frequently Asked Questions
What is the difference between K5PHC3 and K5VHC3?
K5PHC3 has a glass-filled polypropylene head and K5VHC3 has a PVC head. Seals, valve balls and tubing are otherwise the same.
Is K5PHC3 the same as a K5PHC1?
No. The final digit is the connection code. The 3 suffix indicates 1/2-inch OD tubing, while a 1 suffix indicates 3/8-inch OD tubing.
