Import 50: 1 Air Operated Grease Pump — Buy in wholesale FOB from Supplier in China

The 50:1 Air Operated Grease Pump from Shenzhen Yaojienterprise Co.,ltd is a pneumatic lubrication pump designed for high-pressure grease delivery in workshops, mines and heavy-equipment maintenance facilities. It operates on a 50-to-1 compression ratio with a working air pressure of 3 to 8 kgf per cm2 and a maximum pressure output of 8 kgf per cm2. The pump moves grease at an output capacity of 500 to 900 grams per minute while consuming 150 litres per minute of compressed air. Key connection points include a BSF 1/4 inch air inlet and a BSF 3/8 inch grease outlet, with a 32 mm diameter suction tube available in lengths of 410 mm, 740 mm or 940 mm depending on drum or pail size.

The pump body is typically cast from aluminium alloy or steel in this product category, with hardened steel piston and cylinder assemblies to withstand the high mechanical advantage of a 50:1 ratio. Seals are normally nitrile or polyurethane, suited to NLGI grade 2 grease at typical ambient temperatures of minus 10 to plus 60 degrees Celsius. The 32 mm suction tube diameter is standard for accommodating 15 to 20 kg grease containers, while the longer 740 mm and 940 mm variants fit 50 kg and 180 kg drums respectively. Buyers should confirm with Shenzhen Yaojienterprise Co.,ltd whether the pump head includes a follower plate and what seal materials are used, as these are not stated in the source data.

This pump serves automotive service centres, construction machinery fleets, mining maintenance crews and industrial plants that require centralised or point-of-use grease dispensing. The pneumatic drive eliminates electrical spark risk, making it suitable for environments with flammable atmospheres when properly grounded. Typical buyers include equipment dealers, aftermarket parts distributors and MRO procurement teams. Prospective importers should verify with Shenzhen Yaojienterprise Co.,ltd whether the unit ships with a hose,配合使用 gun, or drum cover, as these accessories are not listed and are often necessary for immediate operation.
