Vogelsang presents flexible and efficient
pumps for the agricultural sector
High quality and minimal operating costs.
t the last EuroTier
(November 15th to
18th, 2016, in
Hanover) Hugo
Vogelsang
Maschinenbau
GmbH presented the pump
innovations for the agricultural
sector using the motto "Pumps for
Life". The focus was on the VX
series of rotary lobe pumps.
"Quality pays off. That is what we
stand for and we are continually
developing our VX series of rotary
lobe pumps to ensure that they are
more flexible and easier to
maintain and have a longer service
life," explains Harald Vogelsang,
Managing Director of the specialist
provider for pump, shredding,
distribution and spreading
technology.
VX series: efficient filling
technology for liquid manure
tankers
The VX series is an optimal
solution for liquid manure tankers.
It is high-performing, self-priming,
even from deep pits, insensitive to
foreign matter, compact and low in
A
weight. Technical innovations
enable long durability, thereby
significantly lowering operating
costs. An outstanding example of
such innovation is our patented
InjectionSystem. This integrated
system ensures foreign matter is
injected directly into the pump
chamber and therefore preventing
lobe tips collisions. Experience in
the field has demonstrated
durability can be increased by up
to 2.5 times. At the same time, the
housing geometry enables better
sealing of the lobes to the pump
housing. Due to these benefits, the
InjectionSystem has proven its
worth in the market and is used in
serial production today by reputed
tanker manufacturers.
Low maintenance and assembly
The pump housing is clad with
radial and axial protective plates
made from extra hardened special
steel, which also contributes to
increased durability and ease of
maintenance of Vogelsang rotary
lobe pumps. All rotary lobe pumps
in the VX series are also equipped
with the Quality Cartridge

mechanical seal. This patented
technology encloses all sealing
components and enables the seal
to be replaced in a single working
step. This significantly reduces
maintenance work and any risk of
assembly faults. An optional repair
set is also available for this sealing
system. The pulsation-free HiFlo®
lobes can be replaced easily and
restore the delivery capacity to 100
percent following replacement.
One pump with different drive
types
The Universal Drive System
(UDS) enables the same
Vogelsang rotary lobe pump to be
equipped with different drive types
depending on the type of
application. Combined with a shaft
and drive adapter, the VX series
can be equipped flexibly and
operated with hydraulic and
geared motors as well as the
classic cardan shaft or three-
speed manual gearbox depending
on the application. This is a
concept that eases the
management of spare parts and
increases flexibility.
Controllable flow rate for
precision spreading
The rotary lobe principle is ideal
for precise spreading across the
entire working width and length
due to its speed dependent
delivery volume. Vogelsang offers
two new variants of the speed
sensor in order to control the VX
series, which are integrated
compactly and robustly into the
housings. Screwed directly into
the gearbox, the sensor measures
the speed and is independent of
the drive type. Connected with the
UDS, the speed sensor is installed
in the drive adaptor and measures
the speed on the adapter toothing.
Based on these measurements,
the flow rate is then calculated so
that the desired spreading
capacity can be precisely
regulated.
