Understanding High-Pressure PVC

The W designation identifies a PVC liquid end associated with higher-pressure pump models. It differs from the standard V-designated PVC head. Confirm the original pump rating rather than assuming a pressure limit from the kit number alone.

How to Find the Right KOPkit for Your Pump

Check the pump nameplate or specification data sheet for the KOPkit number. 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-WTC3-XXX takes the K4WTC3 kit.

PTFE Seals and Ceramic Double-Ball Valves

The WTC3 configuration specifies PTFE seats and O-rings with ceramic double-ball check valves. Verify compatibility for your process fluid.

K4WTC3 Versus K4VTC3

K4VTC3 uses the same PTFE seals, ceramic valves and 1/2-inch OD tubing, but with a standard PVC head. K4WTC3 is the high-pressure PVC version. Order the kit that matches the W or V in your wet-end code.

WTC3 Versus WTCJ

The 3 suffix indicates 1/2-inch OD tubing, while WTCJ wet ends use 3/8-inch OD tubing. Confirm the connection size on the original pump before ordering.

Installation Recommendations

Isolate electrical power, relieve discharge pressure and follow the Pulsafeeder service procedure. Confirm the exact supplied kit components before installation.

Frequently Asked Questions

What does the W in K4WTC3 mean?

W identifies a high-pressure PVC head. A V in the same position identifies a standard PVC head.

Can K4VTC3 replace K4WTC3?

Do not substitute without checking the pump documentation. The head construction differs, and high-pressure pumps should be serviced with the matching high-pressure kit.
