Pulsafeeder J20560 Ceramic Check Valve Ball
Pulsafeeder J20560 ceramic check valve ball with 0.31-inch diameter for compatible CHEM-TECH and PULSAtron chemical metering pump valve assemblies.
The Pulsafeeder J20560 is a ceramic check valve ball used as a replacement component in compatible Pulsafeeder chemical metering pump valve assemblies. The ball measures approximately 0.31 inch in diameter.
This small but important component works within the pump check-valve system, helping control the direction of chemical flow during the suction and discharge cycles.
J20560 Product Details
- Part Number: J20560
- Manufacturer: Pulsafeeder
- Product Type: Check Valve Ball
- Material: Ceramic
- Diameter: Approximately 0.31 Inch
- Application: Chemical Metering Pump Check Valve
Ceramic Check Ball Construction
The J20560 is manufactured from ceramic and serves as the moving ball element inside compatible suction and discharge check-valve assemblies.
During pump operation, movement of the ceramic ball against the valve seat helps open and close the fluid path as pressure changes through the pumping cycle.
Role in Metering Pump Operation
A diaphragm metering pump depends on check valves to maintain one-way chemical flow. During the suction stroke, the appropriate valve opens to allow chemical into the pump head. During the discharge stroke, the valve arrangement changes so chemical can leave the pump while reverse flow is restricted.
The J20560 ceramic ball is one of the components that makes this check-valve action possible.
CHEM-TECH Pump Applications
Pulsafeeder documentation identifies J20560 in the valve assemblies of CHEM-TECH Series 100 and Series 150 mechanical diaphragm metering pumps. Replacement-parts documentation also identifies applications involving Series 200 pumps.
PULSAtron Applications
Current Pulsafeeder replacement-parts catalogs also identify J20560 for compatible PULSAtron Series A+, C, C+, E and E-DC pump configurations.
Because individual pump wet ends can use different valve materials, always verify the complete pump model and existing valve configuration before ordering a replacement ball.
Why Check Valve Balls Matter
The check ball repeatedly moves and seats during pump operation. Chemical deposits, contamination or wear at the ball and valve-seat interface can interfere with proper sealing.
A check valve that does not seat correctly may contribute to reduced priming performance, inconsistent chemical delivery or reverse flow through the liquid end.
When to Inspect or Replace J20560
Inspection of the check-valve components may be appropriate when a compatible metering pump experiences symptoms such as:
- Difficulty priming
- Reduced chemical output
- Inconsistent metering performance
- Backflow through the liquid end
- Visible deposits around valve components
- Wear or damage to the existing ceramic ball
Valve Maintenance
When servicing the check valve, inspect the ceramic ball together with the valve seat, gasket and surrounding valve components. A new check ball cannot correct poor sealing if another mating component is damaged, contaminated or chemically deteriorated.
Selection Note
The J20560 is an individual ceramic check valve ball, not a complete suction valve, discharge valve or check-valve assembly. Confirm that the existing pump specifically requires the J20560 ceramic ball before replacement.
