Plunger Height
Adjustment Screw A special locking screw operated with a 2.5mm Allen key that is adjusted from
the top of each pump body to adjust the height of the plunger. A pressure pad
operates on the side of the adjuster screw.
The higher the plunger in relation to the top of the rail the greater the grease
output
Plunger Return
Spring The spring returns the plunger to its static position after the plunger has been
depressed by the train wheel (or manually).
Pump Body Pump contains:
1 plunger (complete with integral non return valve)
1 plunger height adjustment screw
1 plunger return spring
1 grease outlet non-return valve
1 bleed screw
1 delivery hose outlet pipe
1 pump support bracket.
The grease is delivered from the reservoir via the feed hose and fills the
primary chamber of the pump unit. When the system is primed the grease
then fills the secondary chamber via the plunger integral non-return valve.
Once the plunger is depressed by the train wheels, (or manually) the grease is
transferred via the outlet non-return valve to the outlet pipe and then through
to the delivery hoses.
On the return stroke of the plunger its integral non-return valve opens and
allows grease to flow into the secondary chamber from the primary chamber.
Grease Outlet non-
Return Valve The non-return valve acts as a stop valve, preventing the grease in the Blade
path from being drawn back into the pump body as the plunger rises.
Once the plunger is depressed by the train wheel, (or manually), the grease is
transferred from the secondary chamber through the outlet non-return valve,
permitting grease to flow through to the Blade via the delivery hoses.
Bleed Screw Once open, any air trapped in the secondary chamber is able to be released
when the plunger is operated or fully raised.
Delivery Hose There is a specific length of delivery hose supplied with each lubricator, which
has to be cut to fit between a pump body and a Blade assembly.
The hose is secured using a hose clip at each end of the hose.
The delivery hose transfers the grease from the pump outlet to the Blade inlet.
Blade (Grease
Dispensing Unit) The Blade has multiple ports at the top of the grooved plate, which allows the
grease to be delivered to the gauge corner and/or gauge face of the rail for
the train wheels to pick up and spread along the curve.
