The AOCHENG GPT-30 Pneumatic Grease Pump Kit is designed for grease dispensing in industrial maintenance and lubrication service environments. With a 30L capacity, it provides a larger grease supply for recurring maintenance tasks. Its pneumatic pump configuration supports high-pressure grease delivery, making it suitable for workshops, machinery servicing, and other applications where grease needs to be supplied to equipment lubrication points.

The GPT-30 is designed for grease dispensing in industrial maintenance departments, machinery service areas, and mechanical workshops. Its 30L container provides the largest listed capacity in the GPT series, making it an option for maintenance operations that consume more grease or prefer fewer container refills during routine lubrication work.
A 30L container provides a larger grease supply than the 12L GPT-12 and 25L GPT-25. Where grease consumption is relatively high, the additional capacity may help reduce refill frequency and interruptions during maintenance. The practical benefit depends on how much grease each task requires and how frequently the equipment is used.
The GPT-30 is shown with a wheeled base that supports movement between service areas. This configuration can be useful when lubrication tasks take place at different workstations. Buyers should consider floor conditions, available maneuvering space, and the intended operating location when assessing whether this mobile design suits their workflow.
Before installation, confirm that the compressed-air supply, grease type, connection size, hose, and dispensing nozzle are compatible with the application. The catalog lists a 1/4-inch inlet/outlet connection and a maximum pressure of 400 bar / 5800 psi for the series. The complete system must be configured within the ratings of all connected components.
The GPT-30 offers a 30L capacity, compared with 12L for GPT-12 and 25L for GPT-25. It may be preferable when a larger grease supply and a wheeled configuration are useful for maintenance operations. Buyers should also consider container dimensions, unit weight, workshop layout, and expected grease consumption rather than selecting a model by capacity alone.

Pneumatic pumps are suitable for high-pressure applications, manual pumps are compact and user-friendly for smaller machines, while electric pumps offer automated and continuous lubrication for larger machinery in industrial settings.
Higher ratios (60:1) generate greater pressure for long-distance grease delivery, while lower ratios (50:1) provide higher flow rates for quickly filling larger areas. Ratio selection depends on viscosity, application, and equipment compatibility.
Applications include heavy equipment lubrication, automotive and transportation, industrial machinery, wind turbines, railroads, and manual greasing tasks. They deliver grease efficiently to multiple lubrication points in various industries, ensuring smooth operation and extended equipment lifespan.
