The professional dual-piston grease pump is engineered for high-performance lubrication in the most demanding applications. Its dual-piston mechanism allows delivers up to three times the grease output of a conventional grease pump, providing 2.4 g per stroke at pressures of up to 6000 PSI (413 bar). This makes it an ideal solution for applications requiring high volume in a short period of time. Manufactured from high-quality materials, it features a die-cast aluminium head, a 1.2 mm reinforced aluminium wall, a follower spring, and a practical bleeder valve for ease of use. Compatible with 400 g cartridges or bulk loading, it is designed to operate reliably even in extremely cold environments. Ideal for professionals in mechanics, agriculture, industry, or maintenance who require speed, durability and precision in greasing operations. TECHNICAL SPECIFICATIONS: Material: aluminium.
