PULSAtron K3VVC9 KOPkit Pump Head Repair Kit
PULSAtron K3VVC9 KOPkit for size 3 VVC9 wet ends with PVC head components, Viton seals, ceramic valve balls and 3/8-inch connection.
The PULSAtron K3VVC9 is a KOPkit pump head repair and liquid-end maintenance kit designed for compatible size 3 PULSAtron chemical metering pumps equipped with the VVC9 wet-end configuration.
The K3VVC9 combines the principal wet-end components needed for scheduled maintenance and repair. Its documented material configuration includes PVC head components, Viton/FPM valve seats and O-rings, ceramic valve balls and a 3/8-inch connection.

Designed for VVC9 Liquid Ends
The K3VVC9 is matched specifically to size 3 pumps carrying the VVC9 liquid-end code. This code identifies the material and valve configuration used in the pump wet end.
Matching the complete wet-end code is important when selecting a KOPkit because other size 3 PULSAtron pumps can use different head materials, elastomers, valve components and connection arrangements.
PVC Wet-End Construction
The K3VVC9 uses PVC pump-head and wet-end components. PVC is commonly used in chemical metering equipment where its chemical-resistance characteristics are appropriate for the process fluid.
The suitability of PVC should always be confirmed for the specific chemical concentration, temperature and operating conditions of the application.
Viton / FPM Valve Sealing
The VVC9 configuration uses Viton/FPM valve seats and O-rings. These elastomer components provide sealing surfaces within the liquid-end valve arrangement.
Valve-seat and O-ring condition is important for maintaining reliable check-valve operation. Worn or chemically deteriorated sealing components can contribute to poor priming, backflow or inconsistent chemical output.
Ceramic Valve Balls
The suction and discharge check-valve arrangement uses ceramic valve balls. As the pump diaphragm cycles, pressure changes move these balls against and away from their valve seats.
This check-valve action helps maintain one-direction chemical flow through the liquid end.
VVC9 & Off-Gassing Chemical Applications
PULSAtron pumps equipped with the VVC9 configuration are documented for applications involving sodium hypochlorite and other chemicals that may release gas.
Compatible pump configurations may incorporate a degassing arrangement that helps manage gas accumulation in the pump head. The exact configuration should be confirmed from the complete pump model number.
KOPkit Service Components
PULSAtron KOPkits package commonly serviced wet-end components together to simplify pump maintenance. Documented KOPkit contents include:
- Pump head
- Discharge valve assembly
- Suction valve assembly
- Replacement diaphragm
- Pump head screws and washers
- Deflection plate
- Shims
- Secondary seal
- Degassing valve assembly when required for the applicable degas model
Connection Details
The K3VVC9 is identified as a 3/8-inch connection KOPkit. Compatible pump documentation also describes certain size 3 VVC9 pump connections as approximately 0.25-inch ID x 0.38-inch OD.
The existing pump tubing and complete model configuration should be checked before installation.
Documented Compatible Pump Models
Current replacement-parts documentation identifies K3VVC9 for compatible models including:
- LB03SA-VVC9-XXX
- LC03SA-VVC9-XXX
- LD03SA-VVC9-XXX
- LE03SA-VVC9-XXX
These are documented examples rather than an exhaustive compatibility list. Verify the KOPkit number on the pump nameplate or specification data before replacement.
Preventive Maintenance Benefits
The diaphragm, valve seats, O-rings and check balls are exposed to continuous movement and process chemicals during normal metering-pump operation. Servicing these components can help restore dependable liquid-end performance.
- Helps maintain reliable pump priming
- Supports proper check-valve operation
- Helps reduce unwanted backflow
- Supports consistent chemical delivery
- Packages matched wet-end service components together
- Can reduce maintenance downtime
Selection Note
K3VVC9 is specifically configured for size 3 VVC9 wet ends. Confirm the complete PULSAtron pump model, PVC/Viton/ceramic material configuration and connection size before installation.
