Designed for Size 4 Pump Maintenance

K4VTCA is intended for compatible Size 4 PULSAtron liquid ends. Its head size, material combination and wet-end suffix must match the original equipment before replacement.

How to Find the Right KOPkit for Your Pump

Pulsafeeder stamps the KOPkit number on every 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 XXX4XX-VTCA-XXX takes the K4VTCA kit.

PVC Head and PTFE Seals

The PVC pump head and PTFE seats and O-rings are the key identifiers of the VTC configuration. Verify suitability for the chemical, concentration and operating temperature.

K4VTCA Versus K4VTC3

Both kits share the same published PVC/PTFE/ceramic materials and 1/2-inch OD tubing. Their wet-end suffixes differ, so match the complete original pump designation before assuming interchangeability.

K4VTCA Versus K4PTCA

K4PTCA uses the same PTFE seals, ceramic valves and 1/2-inch OD tubing, but with a glass-filled polypropylene head instead of PVC. The first letter of the wet-end code tells them apart.

Typical Kit Contents

Pulsafeeder states that solenoid diaphragm pump KOPkits generally contain a diaphragm, head, check-valve assemblies and associated maintenance components. Verify the exact current K4VTCA packing list.

Installation Procedure

Confirm the Size 4 VTCA configuration, disconnect power, isolate the chemical supply and relieve system pressure before servicing. Follow the official Pulsafeeder KOPkit instructions.
