Pneumatic Grease Gun (Square Pump) - 12L/40L Industrial High-capacity Air-powered Lubrication Pump
Product Overview
The Pneumatic Grease Gun (Square Pump) is a compact and powerful industrial-grade air-powered lubrication device, available in two large-capacity specifications: 12L and 40L. It features a robust black cylindrical grease reservoir with a distinctive red top cover, integrated black carrying handle, and a stable base, offering a solid structure that is easy to move and operate. Powered by compressed air, it delivers sustained high-pressure output, specifically designed to meet the high-intensity, high-frequency centralized lubrication demands in automotive repair shops, for construction and mining equipment, and in large-scale manufacturing plants. As a source manufacturer, we provide comprehensive customization options including capacity, color, and accessories, and support professional OEM/ODM private-label services.
Primary Uses
  • Centralized Maintenance in Automotive & Transport: Ideal for rapid and efficient lubrication of numerous grease points on vehicle chassis, bearings, etc., in truck fleets and bus repair centers.
  • Field Maintenance for Construction Machinery: Provides reliable, continuous lubrication service for equipment like excavators, loaders, and rollers at job sites, even in harsh conditions.
  • Periodic Lubrication of Industrial Production Equipment: Used for systematic, cyclical greasing of multiple lubrication points on key machinery in production lines, such as large machine tools, stamping presses, and conveyor systems.
  • Heavy Equipment Workshops: Serves as a standard lubrication tool in workshops for mining, port, and steel mill equipment, meeting high-volume grease dispensing requirements.
Materials and Construction
  • Grease Reservoir: Manufactured from high-strength steel with a wear-resistant black coating for corrosion and impact resistance. The red top cover ensures a tight seal, effectively preventing dust ingress and leaks.
  • Power & Pump Unit: At its core is a high-efficiency pneumatic motor paired with a professional plunger pump (square pump design). Driven by compressed air, it generates stable, extremely high output pressure. The air inlet line features a standard quick-connect coupling and a filter-regulator unit.
  • Operation & Mobility Components: The barrel incorporates a sturdy black metal carrying handle for easy transport and tilting during operation. The included black metal base ensures stable placement and can be optionally fitted with casters.
  • Delivery System: Connects to an ultra-high-pressure oil-resistant wire-braided hose and a heavy-duty alloy grease gun, ensuring smooth and precise grease delivery.
Core Functions and Features
  • Square Pump Design, High Efficiency & Power: The unique square pump (plunger pump) design, driven by compressed air, generates sustained high pressure far exceeding that of standard pumps, easily handling the thickest greases with exceptional dispensing speed.
  • Large Grease Capacity, Minimizes Downtime: Offered in 12L (standard) and 40L (extra-large) capacities, it is particularly suited for prolonged, multi-equipment continuous lubrication tasks, significantly reducing work interruptions for grease refills.
  • Air-powered, Safe & Reliable: Pure pneumatic operation with no electrical components eliminates spark hazards entirely, making it safe and explosion-proof for oily, wet, or otherwise safety-sensitive environments.
  • Robust & Durable, Easy Maintenance: The all-metal main body and industrial-grade components ensure an extended service life. Modular design allows for simple and quick routine maintenance and replacement of key seals.
  • Portable & Ready-to-Use: The compact cylindrical design with handle and base allows for easy storage and movement to any work point. It is ready for immediate operation upon connection to the workshop air supply.
Specifications
  • Model: Pneumatic Grease Gun (Square Pump)
  • Available Capacity: 12L / 40L
  • Drive System: Pneumatic (requires connection to 6-8 bar compressed air supply)
  • Output Pressure: Ultra-high Pressure (specific range adjustable based on configuration)
  • Standard Quantity: 1 unit
