Positive displacement rotary vane
pumps
MAIN FEATURES
Self priming rotary vane pump with
internal by-pass valve. The pumps use a rotor with sliding vanes to
draw the liquid. The material of
construction is nodular iron with sliding vanes built in a special
self lubricating material. Mechanical seals are available for
different types of liquids. Due to its efficiency the pumps can
handle viscous and also volatile liquids and require less horsepower
than other equivalent pumps. The pumps are capable of higher
flow-rates at lower number of revolutions than other designs.

APPLICATIONS
The pumps are widely used on mobile applications or fixed installations.
With cardan shafts or hydraulic motor the pumps can be installed
on any kind of tank truck or they are coupled to electric or diesel
engine on metal bases to be used either on terminals, heavy duty
dispensers, pumping/metering skids. mobile transfer units. Equipped
with Teflon seals the pumps can also be used on a wide variety of
solvents in the petrochemical industry.
ACCESSORIES
- Strainers
- Hydraulic motor adaptors
