What the K6VTC3 Part Number Means
K identifies a KOPkit and 6 is the head size. In the VTC3 wet-end code, V is the PVC 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. From the 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 XXX6XX-VTC3-XXX takes the K6VTC3 kit.
PVC Head with PTFE Seats
The VTC configuration pairs a standard PVC pump head with PTFE seats and O-rings and ceramic double-ball check valves. Confirm compatibility with the chemical, concentration and temperature being metered.
K6VTC3 Versus K6PTC3 and K5VTC3
K6PTC3 fits the same Size 6 head with the same seals, valves and tubing, but uses a glass-filled polypropylene head instead of PVC. K5VTC3 uses the same VTC3 materials but fits Size 5 pumps. Head size and head material must both match.
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 K6VTC3 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 K6VTC3 fit?

Can I use K5VTC3 on a Size 6 pump?
