Exhibits
The product range includes pumps for grease, engine oil, gear oil, organic solvents and food liquids, as well as hydraulic presses and shock-absorber maintenance equipment. Pneumatic grease-pump families include the American LA series at 45:1, the Japanese SK series at 55:1 and the European BW series at 80:1. LA101, LA201 and LA301 are 45:1 models for 20 liters (5 gallons), while LA401, LA501 and LA601 are 45:1 models for 200 liters (50 gallons). BW101, BW201 and BW301 are 80:1 models for 20 liters (5 gallons), while BW401, BW501 and BW601 are 80:1 models for 200 liters (50 gallons). SK101, SK201 and SK301 are 55:1 models for 20 liters (5 gallons), while SK401, SK501 and SK601 are 55:1 models for 200 liters (50 gallons). Pressurized pneumatic fluid pumps include HV301C at 45:1 for 20 liters (5 gallons) and HV302 at 32:1 for 20 liters of shield-tail oil or ink. Dual-column pressurized fluid pumps include HV102 at 50:1 for 20 and 25 liters, HV103 at 45:1 for 200 liters (50 gallons), HV104 at 50:1 for 200 liters (50 gallons) and HV106 at 55:1 for a 1kg easy-open can. The catalog also covers pneumatic oil pumps for 0#–120# oil and pneumatic gear-oil pumps for 140#–200# oil. Organic-solvent and food-liquid products include a pneumatic organic-solvent pump and a stainless-steel food-grade pneumatic fluid pump. The lubrication lineup also includes manual pumps, grease guns, oil guns, flow meters, oil-drum carts, reels, pressure plates, drum covers, pressure-reducing and regulating valves and filters. Metering and automation products include precision metering valves, high-pressure precision metering valves, large-capacity precision metering valves, pneumatic valves and a numerical-control quantitative oiling system. A standard 100-mesh stainless-steel filter is used to remove fine particles from oil; when blocked, the upper and lower plugs can be removed and debris blown out with an air gun so the filter can operate again without consumable media. The company links its automated quantitative oiling technology with industrial automation goals that include lowering cost, improving efficiency and supporting automated production lines.
Company profile
JO LONG MACHINE INDUSTRIAL CO., LTD. was established in 1976 and initially focused on producing various special-purpose machines. In 1991, the company began producing lubrication equipment and automotive and motorcycle maintenance tools under its own JOLONG trademark. The company states that it has worked for more than 40 years to provide products for industrial users and continues product research and development. Its quality policy emphasizes quality first, customer satisfaction and continuous improvement, with professional and data-based testing applied to products. Production equipment includes CNC numerical-control lathes, CNC machining centers, hydraulic presses and integrated numerical production equipment. Inspection equipment includes a 2D image measuring instrument and an electron microscope, while a pump tester is used to produce data-based test results. Key components are produced in-house using CNC machining centers and CNC numerical-control lathes to support quality control. Integrated production equipment and dedicated assembly machines are used to improve production yield and reduce uncertainty from manual assembly.
