Pulsafeeder J30511 FPP/CSPE Hypalon Bleed Valve Kit - 3/8-Inch

Pulsafeeder J30511 FPP/CSPE Hypalon Bleed Valve Kit

The Pulsafeeder J30511 is an FPP/CSPE bleed valve kit with a 3/8-inch tubing connection for compatible CHEM-TECH chemical metering pumps. The manufacturer parts schedule identifies its sealing configuration as CSPE, also commonly referenced as Hypalon.

CSPE-Sealed Bleed Valve Configuration

J30511 is distinguished by its CSPE/Hypalon sealing material. It is not the same as J30513, which uses Viton, or J30514, which uses PTFE. The original pump wetted-material configuration should determine the correct replacement.

Air Venting During Priming

Gas trapped in the pump liquid end can interfere with normal chemical intake and discharge. During the manufacturer-recommended priming procedure, the bleed valve provides a path for releasing trapped air through the designated connection.

Material Compatibility

CSPE is an elastomer used in selected chemical-handling applications. Its suitability depends on the actual chemical, concentration and temperature. Confirm compatibility of the entire wetted assembly before installation.

Difference from PVC/Hypalon Kits

J30511 uses an FPP body, whereas J30507 is listed as a PVC/Hypalon kit with the same nominal 3/8-inch tubing size. Housing material is therefore another important selection factor beyond the seal designation.

Maintenance and Replacement

Inspect the valve for deposits, leakage, damaged tubing connections and worn sealing components. Isolate the chemical supply and relieve pressure before servicing the pump.
