Diaphragm Function in a Metering Pump
The diaphragm is a flexible component that separates the pump drive mechanism from the chemical liquid end. Its reciprocating movement changes the volume inside the pump chamber, allowing chemical solution to be drawn in and discharged through the pump check valves.
TFE and Hypalon Construction
The manufacturer describes this replacement as a TFE/Hypalon diaphragm. Material selection is important because the diaphragm must tolerate repeated flexing while remaining suitable for the chemical service conditions specified for the original pump.
Size 7 Compatibility Verification
The official PULSAtron parts guide lists L0301400-THY for size 7 variants of certain wet ends, including PVT3. Confirm the complete pump model and original diaphragm part number before ordering. Size designation alone does not establish compatibility with every PULSAtron model.
Inspection and Replacement
Inspect diaphragms according to the pump maintenance schedule. Signs of damage may include chemical leakage, reduced output or visible deterioration. These symptoms can have other causes, so inspect the full liquid end when troubleshooting.
Safe Maintenance
Disconnect power, isolate the chemical supply, drain and depressurize the liquid end before diaphragm replacement. Follow the manufacturer procedure for assembly and tightening requirements.
