What the K5PTC3 Part Number Means
Every PULSAtron KOPkit number follows the same pattern. K identifies a KOPkit and 5 is the head size. In the PTC3 wet-end code, P is the glass-filled polypropylene head, T is PTFE seats and O-rings, C is ceramic check-valve balls and 3 is the 1/2-inch OD tubing connection.
How to Find the Right KOPkit for Your Pump
Pulsafeeder stamps the KOPkit number on the pump nameplate and lists it on the pump specification data sheet. You can also build it from the pump model number: the fourth character is the head size and characters seven through ten are the wet-end code. A pump model in the format XXX5XX-PTC3-XXX takes the K5PTC3 kit.
Glass-Filled Polypropylene and PTFE Materials
The FPP pump head and PTFE seats and O-rings define the PTC3 material configuration. Verify compatibility with the chemical, concentration and temperature being metered before installation.
K5PTC3 Versus K4PTC3 and K5PHC3
K4PTC3 uses the same PTC3 materials and tubing but fits Size 4 pumps, so the two are not interchangeable. K5PHC3 fits the same Size 5 head with the same FPP head and tubing, but uses CSPE/Hypalon seats and O-rings instead of PTFE.
Typical Kit Contents
According to Pulsafeeder, solenoid diaphragm pump KOPkits typically contain a diaphragm, pump head, check-valve assemblies and related model-dependent service parts. Confirm the exact K5PTC3 package contents before installation.
Installation and Safety
Disconnect electrical power, isolate the chemical feed and relieve system pressure before servicing. Follow the official Pulsafeeder KOPkit installation instructions.
Frequently Asked Questions
Which pumps does the K5PTC3 fit?
It fits PULSAtron pumps with a Size 5 head and a PTC3 wet end. Check that the pump nameplate lists K5PTC3 or that the model number matches XXX5XX-PTC3-XXX.
Can I use K4PTC3 on a Size 5 pump?
No. Head size must match. K4PTC3 is built for Size 4 liquid ends only.
How often should a KOPkit be replaced?
Service intervals depend on the chemical, duty cycle and operating conditions. Many operators keep a spare KOPkit on hand and replace it as part of scheduled preventive maintenance.
