Threaded NPT Connections
The final digit 2 identifies a 1/4-inch NPT threaded connection rather than a compression tubing fitting. This makes K4VTC2 suited to installations that use rigid piping or threaded adapters at the pump liquid end.
PVC Head with PTFE Seats
The VTC configuration pairs a standard PVC pump head with PTFE seats and O-rings. Confirm that PVC and PTFE are compatible with the chemical, concentration and temperature being metered.
Ceramic Double-Ball Check Valves
The C designation identifies ceramic check-valve balls in a double-ball arrangement. This should not be confused with 316 stainless steel or PTFE ball configurations used in other PULSAtron kits.
VTC2 Versus VTC1 and VTC3
K4VTC1 and K4VTC3 share the same PVC/PTFE/ceramic material combination but use 3/8-inch and 1/2-inch OD tubing connections respectively. K4VTC2 is the threaded NPT variant. Match the complete original wet-end code before ordering.
Preventive Maintenance Benefits
PULSAtron KOPkits group common liquid-end service components into one replacement package, helping simplify scheduled maintenance and reduce delays when diaphragm or check-valve parts require service.
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 K4VTC2 package contents before installation.
Installation and Safety
Disconnect electrical power, isolate the chemical feed and relieve system pressure before servicing. Use a compatible thread sealant on NPT connections and follow the official Pulsafeeder KOPkit installation instructions.
