PULSAtron K3KTC1 PVDF/PTFE KOPkit

Restore the liquid end of a compatible PULSAtron metering pump with the PULSAtron K3KTC1 KOPkit. This maintenance kit is engineered for size 3 pumps using the KTC1 wet-end configuration and brings the primary service components together under one replacement part number.

The K3KTC1 configuration is built around PVDF wetted components, TFE/PTFE sealing materials and ceramic check balls. It is designed for the KTC1 connection arrangement using 0.25-inch ID x 0.38-inch OD tubing, commonly described as a 3/8-inch OD connection.

What K3KTC1 Identifies

The K3KTC1 part number identifies a specific PULSAtron KOPkit configuration rather than a universal pump repair kit:

• K3: Size 3 pump-head configuration
• KTC1: PVDF/PTFE/ceramic KTC1 wet-end arrangement
• Head & Fittings: PVDF
• Seats / O-Rings: TFE / PTFE
• Valve Balls: Ceramic
• Tubing: 0.25-Inch ID x 0.38-Inch OD
• Nominal Connection: 3/8-Inch OD Tubing

PVDF Liquid-End Components

The KTC1 wet end uses PVDF for the documented head and fitting configuration. PVDF is widely used in chemical-feed equipment where its chemical-resistance properties are appropriate for the process fluid.

Material compatibility should still be checked against the actual chemical, concentration, temperature and operating conditions of the application.

PTFE Sealing Surfaces

The K3KTC1 configuration uses TFE/PTFE seats and sealing components. These components form part of the sealing arrangement inside the liquid end and check valves.

Proper sealing is particularly important in a metering pump because worn or contaminated valve seats can interfere with priming and accurate one-direction chemical delivery.

Double Ceramic-Ball Valve Configuration

PULSAtron catalog nomenclature describes K3KTC1 as PVD/TFE/CDBL. The CDBL designation refers to the ceramic double-ball check-valve configuration used with this wet end.

The guided seat-and-ball arrangement responds to pressure changes generated by diaphragm movement, allowing chemical to enter and leave the liquid end in the intended direction.

Designed as a Complete Maintenance Solution

A KOPkit is intended to simplify routine liquid-end maintenance. Rather than sourcing the commonly worn pump-head components individually, the kit groups the matched service parts under the K3KTC1 number.

PULSAtron KOPkit documentation describes these kits as including the pump-head assembly with suction and discharge valve cartridges, diaphragm, head screws, washers and related wet-end service components.

Common KOPkit Service Components

• Pump head assembly
• Suction valve cartridge / assembly
• Discharge valve cartridge / assembly
• Replacement diaphragm
• Valve sealing components
• Pump-head screws
• Washers
• Associated wet-end maintenance parts

Kit contents can be revised by the manufacturer, so the current package contents should be confirmed when ordering.

3/8-Inch OD Tubing Arrangement

The K3KTC1 is documented with a 0.25-inch ID x 0.38-inch OD tubing connection. Replacement-part suppliers commonly simplify this measurement to a 3/8-inch connection.

This connection should be verified against the existing pump because similar PULSAtron KOPkits are available with larger tubing or threaded connections.

Verified PULSAtron Pump Applications

K3KTC1 is documented as the required KOPkit for several size 3 PULSAtron KTC1 configurations. Verified examples include:

• LB03SA-KTC1-G19
• LB03EA-KTC1-XXX
• LC03SA-KTC1-XXX
• LD03SA-KTC1-XXX
• LPA3SA-KTC1-500
• LPB3MA-KTC1-XXX
• LPK3MA-KTC1-XXX

This list represents documented examples and should not be treated as the complete compatibility range. Matching the K3KTC1 KOPkit number or complete KTC1 pump model is the safest method of selecting the service kit.

When Liquid-End Service May Be Needed

Routine inspection of the liquid end can help identify wear before it causes a significant reduction in pump performance. Service may be appropriate when:

• The pump becomes difficult to prime
• Chemical output becomes irregular
• The pump loses prime after shutdown
• Check valves contain deposits or contamination
• The diaphragm or sealing components show wear
• Preventive maintenance is due

Why Use the Matching KOPkit?

Using the correct KOPkit keeps the replacement components matched to the original wet-end configuration. For K3KTC1, that means maintaining the documented size 3, PVDF, PTFE and ceramic-ball arrangement rather than mixing parts intended for a different liquid end.

Selection Reminder

Choose K3KTC1 when the pump documentation calls for this exact KOPkit or confirms a compatible size 3 KTC1 wet end. Verify the complete pump model and the 3/8-inch OD tubing arrangement before installation.
