What the K5VTT4 Part Number Means
K identifies a KOPkit and 5 is the head size. In the VTT4 wet-end code, V is the PVC head, the first T is PTFE seats and O-rings, the second T is PTFE valve balls and 4 is the 1/4-inch NPT threaded connection.
How to Find the Right KOPkit for Your Pump
Pulsafeeder stamps the KOPkit number on the pump nameplate and lists it 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 XXX5XX-VTT4-XXX takes the K5VTT4 kit.
Threaded NPT Connections
The 4 suffix identifies 1/4-inch NPT threaded connections instead of compression tubing fittings, for installations that use rigid piping or threaded adapters at the liquid end.
PTFE Seats and PTFE Valve Balls
The VTT configuration uses PTFE for both the seats and O-rings and the double-ball check valves. Confirm that PVC and PTFE suit the chemical, concentration and temperature being metered.
K5VTT4 Versus K5PTC4
K5PTC4 also uses 1/4-inch NPT connections on a Size 5 head, but with a glass-filled polypropylene head and ceramic double-ball valves. Match the complete wet-end code before ordering.
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 K5VTT4 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 instructions.
