Decoding the PTT3 Wet End
P identifies the glass-filled polypropylene head, the first T identifies PTFE seats and O-rings, the second T identifies PTFE 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. 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-PTT3-XXX takes the K5PTT3 kit.
PTFE Valve Balls
PTFE check-valve balls replace the ceramic balls used in PTC3 kits. Match the ball material to the original pump and the chemical being metered.
K5PTT3 Versus K5PTC3
K5PTC3 shares the Size 5 FPP head, PTFE seals and 1/2-inch OD tubing but uses ceramic double-ball valves. The third letter of the wet-end code tells them apart.
K5PTT3 Versus K6PTT3
K6PTT3 uses the same PTT3 materials and tubing but fits Size 6 pumps. Head size must match the original pump.
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.
