2Description components
2.1 Properties
The pump unit is the heart of the OnePlus automatic greasing system. The
Groeneveld
OnePlus pump is a Low Cost solution for compact off-road machines,
industrial machines and trucks that specifically require NLGI-2 grease and do not
have a compressed air system.
The system will automatically lubricate all points connected to the lubrication
system on a timed cycle, with the correct quantity of grease.
The most significant properties of the OnePlus pump unit are:
• Single grease outlet port.
• Interval time and the grease output quantity can be adapted with two rotary
selection switches on the control unit behind the bottom cover of the pump.
• The control unit monitors the electrical wiring and components.
• The system can be extended with an optional block monitoring switch for
guarding the functionality of a distribution block in the system.
• The indicator lamp, supplied with the optional block switch warns the
operator for serious system errors.
ATTENTION
The minimum grease level and the opening of the maximum pressure re-
lieve valve are not monitored by the controller in the pump.
