Maintaining Chemical Metering Performance
Liquid-end components can wear or accumulate deposits during normal pump operation. The correct KOPkit supports planned replacement of common service parts while preserving the original pump configuration.
Ceramic Double-Ball Check Valves
The CDBL designation identifies ceramic double-ball check valves. This arrangement should not be confused with PTFE double-ball or single-ball valve configurations used in other PULSAtron kits.
FPP and PTFE Materials
Glass-filled polypropylene head construction and PTFE sealing components are specified for the PTC3 wet end. Check chemical compatibility against the intended fluid, concentration and temperature.
Connection Identification
K4PTC3 uses 1/2-inch outside-diameter tubing. The related K4PTC1 uses 3/8-inch outside-diameter tubing. Verify the original fittings before ordering a replacement kit.
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 4 head designation.
- Verify the PTC3 wet-end code.
- Check FPP and PTFE material requirements.
- Inspect the tubing and valve components.
- Depressurize and isolate the pump before service.
