AT series gas-liquid booster pump is a single-drive double-acting liquid booster pump with compressed air, which has the advantages of high safety, high output pressure and larger flow.

Features


1. The output pressure can reach up to 3320bar, and the output flow is larger than that of the AH series under the same pressure ratio;
2. The gas drive ensures that the medium does not generate heat, sparks and flames during the transmission process, and the pressurization is safe;
3. The driving gas pipeline does not need to be lubricated, which saves costs and prevents pollution;
4. It is suitable for most liquids and liquefied gases, and can maintain pressure without energy consumption at a predetermined pressure, automatically absorb liquid, automatically maintain pressure, and automatically replenish pressure;
5. The product has compact structure, strong reliability and application fields;

Main features


1. AT series is based on static pressure, when the driving air pressure is 7bar, the air consumption is 1.0m3/min;
2. The driving pressure is 1bar-8.3bar (14.5-120.35psi), and the AT series is a single driving piston (Φ160mm)
3. The high-pressure end is made of stainless steel, and the driving part is made of aluminum alloy;
4. The medium of AT series standard products is water and oil, and the order code is: AT64 (series code + boost ratio)
Description of special products:
About medium: AT series can be applied to various media such as brake fluid and liquefied gas, order code such as: AT20-CO2(series code + boost ratio + boost medium)
About the interface: If you need a special interface, please specify when ordering.

Application scenarios


1. AT series gas-liquid booster pump is suitable for occasions with high output pressure and flow requirements;
2. Hydraulic test/burst test (including but not limited to valves, pressure vessels, pressure switches, hoses, BOPs and other pressurized components;
3. Boosting of vehicle braking system;
4. Calibration of pressure gauges and sensors;
5. Water jet for cutting and cleaning;
6. Leak test, oil and gas well shutdown system;
7. Operation and control of wellhead equipment;
8. Lifting of hydraulic lifting structure;
