TriPlus

Progressive NLGI-2 automatic lubrication system

TriPlus is a unique progressive lubrication system that offers the possibility of three independently operating circuits. It is the ultimate solution for machines and vehicles which have different components requiring different lubrication, such as wheeled excavators, cement pumps or mixers and backhoe loaders.

The main benefits at a glance

  • Up to three independently operating lubrication circuits
  • Grease delivery independently of the ambient temperature
  • Optimal grease dosage per lubrication point
  • Equipped with a follower plate that ensures that all the grease in the reservoir is used. This means that the reservoir wall remains clean, allowing to check the grease level visually. Ageing of the grease as a result of oxidation is also prevented
  • Filling coupling with filter prevents contamination of the grease during refilling
  • In-cab display for settings and system monitoring

Applications

The TriPlus is suitable for many applications. A number of possible applications are shown below. You are welcome to contact Groeneveld for tailored advice.

Follower plate

Like all of Groeneveld's refillable lubrication systems, the TriPlus has a follower plate, which assures that the grease in the reservoir is isolated from the outside air, preventing oxidation and ageing of the grease, dirt and water. In addition, the follower plate keeps the reservoir clean so that the grease level always remains visible and UV radiation will have less effect.

Three lubrication circuits

The TriPlus has three lubrication circuits that can be programmed and operate independently. An ideal solution for inter alia, backhoe loaders, where the front of the machine does not need to be lubricated when the rear excavation arm is being used and vice versa. This prevents the unnecessary lubrication of components that are not moving. Other examples are the undercarriage and crane assembly of a mobile excavator, or a truck chassis and a cement mixer or pump body.

Control unit

The control unit is the heart of the TriPlus. This electronic control unit, with a real-timer clock and memory, ensures that each lubrication circuit receives the exact amount of grease that has been programmed. These settings can always be adjusted to changing working conditions. The in-cab display allows the operator to check the system's operation easily. The comprehensive diagnosis indications make maintenance simple and allow remote assistance. The readable memory makes it easy to assess the system’s past functioning, such as the timely refilling of the grease reservoir.

Temperature independent

In the case of progressive lubrication systems, the grease delivery of the pump is normally based on time. As temperature has a major effect on how well the grease can be pumped, the grease delivery can fluctuate considerably. This does not apply to the TriPlus, as the grease delivery is measured based on the actual number of pump revolutions. In this way, the exact pre-set amount of grease is provided.

Divider blocks

Groeneveld's progressive divider blocks stand out because of their unique quality and combination possibilities. This allows exactly the right system to be assembled for each and every application, where each lubrication point always receives the correct amount of grease. Not too little, preventing metallic contact (and causing disturbing sounds), excessive wear and unexpected downtime. And certainly not too much, because waste and environmental pollution have no place in a good business practice.
For its progressive systems, Groeneveld provides anti-corrosive divider blocks with a high quality zinc-nickel coating. This treatment withstands a 720-hour salt-spray test and thus offers the best possible protection against corrosion.

System overview

The TriPlus automatic lubrication system consists of the following components:

  1. An electric pump (plunger pump) 
  2. Primary grease lines between the pump and the divider blocks and between the divider blocks themselves
  3. Main divider block
  4. One or more divider blocks (composed of various metering segments)
  5. Grease lines to the lubrication points
