Vaporless Manufacturing

Vaporless LD-2100 or PLC-5000 with 98LD-2000PLC
(for Rigid and Flexible Pipelines)


Certification Leak rate of 3.0 gph at 10 psi* with PD = 100% and PFA = 0%.
Leak rate of 0.2 gph at operating pressure with PD = 100% and PFA = 0%.
Leak rate of 0.1 gph at 1.5 times operating pressure* with PD = 100% and PFA = 0%.
*Since leak rate varies as a function of pressure, this leak rate and pressure were certified using an equivalent leak rate and pressure, in accordance with an acceptable protocol.
Leak Threshold 2.5 gph for leak rate of 3.0 gph.
0.136 gph for leak rate of 0.2 gph.
0.068 gph for leak rate of 0.1 gph.
A pipeline system should not be declared tight if the test result indicates a loss that equals or exceeds this threshold.
Applicability Gasoline, diesel, aviation fuel.
Other liquids may be tested after consultation with the manufacturer.
Specification System tests pressurized flexible, fiberglass and steel pipelines.
Tests are conducted at operating pressure.
Pipeline Capacity Maximum of 172 gallons for rigid pipelines.
Maximum of 39.5 gallons for flexible pipelines.
Waiting Time None between delivery and testing.
None between dispensing and testing.
Test Period Response time is less than 8 minutes for leak rate of 3.0 gph.
Response time is 1 hour, 48 minutes to 10 hours, 54 minutes for leak rates of 0.2 and 0.1 gph.
System Features Permanent installation on pipeline.
Automatic testing of pipeline.
Preset threshold. Single test to determine if pipeline is leaking.
LD-2100 is a stand alone system.
PLC-5000 must be coupled with the 98LD-2000.
Pump shutdown, message display and alarm activation if leak is declared.
Calibration Equipment must be checked annually for capability of detecting a line leak of 3.0 gph and, if necessary, calibrated in accordance with manufacturer's instructions.
