PULSAtron K3WTC1 KOPkit Pump Head Repair Kit

The PULSAtron K3WTC1 is a KOPkit liquid-end replacement and pump head repair kit for compatible size 3 PULSAtron chemical metering pumps equipped with the WTC1 wet-end configuration.

The K3WTC1 provides the major wet-end components used during preventive maintenance and repair. Its documented configuration combines a PVC pump head and fittings, TFE/PTFE seats and O-rings, ceramic valve balls and a 3/8-inch OD tubing connection.

Built for Size 3 WTC1 Wet Ends

The K3WTC1 is specifically matched to PULSAtron pumps carrying the size 3 WTC1 liquid-end code. The wet-end code is important because it identifies the materials and connection arrangement required for the pump.

Other size 3 PULSAtron KOPkits can use different head materials, valve-seat materials, valve balls or connection configurations, so the complete wet-end code should be confirmed before replacement.

PVC, PTFE & Ceramic Configuration

The WTC1 configuration uses a PVC pump head and fittings with TFE/PTFE seats and O-rings. The suction and discharge check-valve arrangements use ceramic valve balls.

This material combination is documented for compatible WTC1 chemical metering pumps. Chemical compatibility should still be checked for the actual chemical, concentration, temperature and operating conditions.

Liquid-End Replacement Components

PULSAtron KOPkits are designed to package the principal wet-end maintenance parts together. Documented KOPkit components include:

• Replacement diaphragm
• Pump head
• Check valve assemblies
• Deflection plate
• Shims
• Secondary seal
• Associated liquid-end hardware
• Installation instructions

The exact components supplied should be verified against the current K3WTC1 kit documentation when ordering.

Ceramic Check Valve Balls

The K3WTC1 uses ceramic valve balls within its check-valve system. During operation, pressure changes caused by diaphragm movement allow the check balls to move away from or return to their valve seats.

This guided seat-and-ball action helps maintain one-direction chemical flow through the liquid end and supports consistent metering performance.

Connection Details

The documented WTC1 connection is 0.25-inch ID x 0.38-inch OD tubing. This is commonly described as a 3/8-inch OD tubing connection in replacement-parts listings.

The tubing dimensions should be verified before installation because other PULSAtron wet-end configurations may use different connection sizes.

Documented PULSAtron Applications

K3WTC1 is documented as the required KOPkit for multiple size 3 WTC1 pump configurations. Examples include:

• LBC3SA-WTC1-XXX
• LBC3SB-WTC1-XXX
• LPD3MA-WTC1-XXX

Additional size 3 PULSAtron pumps carrying the WTC1 wet-end code may also use K3WTC1. Confirm the complete pump model before ordering.

Why Use a KOPkit?

The diaphragm, valve seats, check balls, seals and other wet-end components are exposed to continuous mechanical cycling and process chemicals. Their condition can affect priming, valve sealing and chemical delivery.

Using the correct KOPkit allows several commonly serviced components to be replaced together rather than identifying and ordering individual wet-end parts separately.

Maintenance Benefits

• Matched specifically to size 3 WTC1 wet ends
• Provides commonly serviced liquid-end components
• Supports reliable pump priming
• Helps restore proper check-valve operation
• Supports consistent chemical metering
• Simplifies preventive liquid-end maintenance

Selection Note

Before installing K3WTC1, confirm that the pump uses a size 3 WTC1 wet end with PVC head components, PTFE/TFE sealing, ceramic valve balls and a 3/8-inch OD tubing connection.
