The VP sectional progressive metering de-
vice is available in the designs VPM (metric
threaded connectors) and VPG (inch thread-
ed connectors).
With their metering device sections (meter-
ing sections), VPM and VPG cover a nominal
volume per outlet and cycle of 0.1 cm
3 (twin
section) to 1.2 cm 3 (single section).
The inlet of the metering device is located
at an inlet section. The outlets are at the
downstream metering device sections. The
delivery ducts are sealed by elastic seals
(plates). An end section is located down-
stream of the last metering device section.
All sections are interconnected with tie-rods.
They seal the metering device assembly.
The volumetric flow fed via a tube is forcibly
distributed in a predetermined ratio to the
outlets, i.e., to the lubrication points or the
downstream progressive metering devices.
Pistons aligned in series meter the lubricant
for two opposite outlets each and control the
function of the neighboring piston. This way,
the function of the sectional metering device
