Decoding the PTC3 Wet End
In the PTC3 code, P identifies the glass-filled polypropylene head, T identifies PTFE seats and O-rings, C identifies ceramic check-valve balls and 3 identifies the 1/2-inch OD tubing connection. The leading K6 marks a KOPkit for Size 6 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 XXX6XX-PTC3-XXX takes the K6PTC3 kit.
Glass-Filled Polypropylene Head
The FPP pump head distinguishes K6PTC3 from the PVC-headed K6VTC3. Both use PTFE seals, ceramic double-ball valves and 1/2-inch OD tubing, so the head material is the deciding factor when ordering.
K6PTC3 Versus K6PTC4
K6PTC4 uses the same FPP/PTFE/ceramic materials on a Size 6 head but with 1/4-inch NPT threaded connections instead of 1/2-inch OD tubing. The final digit of the wet-end code identifies the connection.
K6PTC3 Versus K6PHC3
K6PHC3 shares the Size 6 FPP head, ceramic valve balls and 1/2-inch OD tubing, but uses CSPE/Hypalon seats and O-rings instead of PTFE. 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 6 head designation.
- Verify the PTC3 wet-end code on the nameplate.
- Check FPP, PTFE and ceramic material requirements.
- Inspect the tubing and valve components.
- Depressurize and isolate the pump before service.
