TrustLube® - Xtreme Grease is a modern high performance product, suitable for extreme applications in heavy industries. The extreme load carrying capacity and consistency make the product the first choice for marine applications with extreme loaded equipment. The grease is easily pumpable in TrustLube® systems despite its high base oil viscosity.
The functional thickener in TrustLube® - Xtreme Grease gives the product extreme load carrying capacity, making it suitable for heavily loaded applications. The grease has an excellent mechanical stability, good corrosion protection and water resistance which are important in wet and corrosive environments.
Air pressure drives the piston in the pneumatic motor. The piston pumps the lubricant, through the cylinder and check valve, to the pump exit. The pump is operated by an electric air valve, which pressurizes the pump cylinder. When the pump is depressurized, a compression spring returns the piston to its starting position and re-fills pump exits with a specified amount of lubricant.
The pump itself is connected to two main lines, through the use of a switch over valve. On its first cycle, the lubricant is pumped through main line 1. The main line supplies the metering devices with lubricant.
The pistons of the metering devices are moved in to their adjusted end positions, thus dispensing an exact metered quantity of lubricant. Once all the metering devices have dispensed their lubricant to the lubrication point, the system is hydraulically closed. This causes the pressure to rise in main line 1.
The system controller now turns off the pump and switches the change-over-valve to main line 2. Now the second cycle starts, which is identical to the first, but makes use of main line 2. After the cycle is completed the system switches back to main line 1.
The pump has a double action design. This allows for grease dispensing on both the up and down stroke, which guarantees a steady and continues delivery. It is operated pneumatically by an air motor and comes with a follower plate to avoid kedging in the grease.
