PVC, PTFE and Ceramic: The VTC Configuration
The VTC material code pairs a standard PVC pump head with PTFE seats and O-rings and ceramic double-ball check valves.
How to Find the Right KOPkit for Your Pump
The KOPkit number is stamped on the pump nameplate and listed on the 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 model in the format XXX4XX-VTCJ-XXX takes the K4VTCJ kit.
VTCJ Versus VTC1
VTCJ and VTC1 both use 3/8-inch OD tubing with the same PVC/PTFE/ceramic materials. Their suffixes differ, so do not assume the kits are interchangeable without checking the original pump designation.
VTCJ Versus VTCA and VTC3
K4VTCA and K4VTC3 share the same materials but use larger 1/2-inch OD tubing. K4VTCJ is the 3/8-inch OD version. K4VTC2 is the 1/4-inch NPT threaded version.
Typical Maintenance Components
Solenoid diaphragm pump KOPkits generally include a pump head, diaphragm, check-valve assemblies and associated service components. Verify the exact contents of the supplied K4VTCJ kit.
Installation and Safety
Disconnect electrical power, isolate the chemical supply and relieve system pressure. Follow the official manufacturer installation instructions.
