Description
DURR Fuel Dispenser Vapor Recovery Vacuum Pump
The JH - VR Vapour Recovery Pump is a type of vacuum pump equipped with integrated flame arresters on both the inlet and outlet sides. Its main function is to suck explosive fuel vapour/air mixtures into the vapour recovery devices of dispensing units at filling stations.
Features and Benefits
- Protection System: In case of ignition at the dispensing valve, this system prevents flame breakthrough during deflagrations or stable detonations of explosive vapour/air mixtures within the explosion group. It is applicable for specific hose and pipe lengths. For example, it can handle a gas return hose with an internal diameter < 10mm in a coaxial hose < 6mm, or an optional coaxial hose < 6mm with an outer diameter < 38mm, followed by an ID 15 pipe (G 1/2”) < 3mm.
- Temperature Limit: The gas temperature in the outlet line should be maintained within 95°C ± 5°C.
- Product Maintenance: To ensure proper functioning, the product must be kept clean.
- Pump Head Options: Users can choose between a single pump head or a double pump head.
- Factory Testing: All pumps undergo 100% factory testing.
Advantages of the Vapour Recovery Pump
- Safety and Reliability: These pumps are designed for safe use at filling stations globally. The integrated flame arresters on the inlet and outlet sides provide maximum safety. They are also suitable as flame arresters in GR systems and comply with ATEX explosion - protection standards.
- High - Quality and Durability: With self - adjusting piston seals, they maintain a constant volume flow throughout their service life. The patented prechamber with a drainage system makes them insensitive to condensate and liquid.
- Energy - Efficiency and Economy: Thanks to their long service life, they are economical in the long run.
- Versatility: They are available with either belt drive or direct drive options. The motors can operate at 380V or 220V, with 1 - Cylinder or 2 - Cylinder configurations.
- User - Friendly Design: Ideal for dispensers with only one dispensing side, they are ATEX certified, oil - free, and maintenance - free. They are resistant to condensate and liquid, with rotation independent of pump orientation. The noise level is less than 70 dB(A), and they have a protection class of IP10. They can operate in a wide temperature range from - 40°C to + 60°C.
