Hand operated grease pump - depression model - 300/800 cm³

Hand operated grease pump - depression model - 300/800 cm³

Advantages:

• Has a smooth adhesion to the lubricating surface with the correct grease capacity, so no excess grease is leaked
• You don't have to worry about the dirt and impurities that have entered the grease port, so tidier than other ways of greasing
• Use of a single tube, so no return pipe required
• With simple guidance for the best effect

Instructions:

• When moving the operating rod, the plunger (iron core) is moved simultaneously to allow the cylinder to come under negative pressure. Due to the closed air pressure of the tank, the grease then enters the cylinder through the suction opening. Now operate the rod to push the grease through the tube into the cylinder by pressing the plunger and pushing the non-return valve open. When the internal pressure reaches the specific pressure of 100 kg / cm², the downward pressure valve will return the grease to the tank.
