Durable Bauer Magnum SX for
reliable, low maintenance slurry
and AD digestate pumping
applications
The ‘beating heart’ of many a contractor’s umbilical system for applying
slurry and AD plant digestate to the land is a Bauer Magnum SX2000
centrifugal pump.
owered by an auxiliary diesel
engine or tractor pto, its role is
to extract liquid from store and
send it on its way to distant
field application sites – with a
booster pump installed part
way along the supply pipe if necessary.
Having a reliable pump with plenty of
capacity is essential to get the best
performance out of an umbilical system, which
has the big attraction of relieving fields of heavy
tankers and the soil compaction that can be
caused with even the biggest and best flotation
tyres fitted.
Reliability is another key asset and
contractors often say they are comfortable
operating Magnum SX pumps remotely
because they have been so reliable over the
years – they are tough, hard-wearing and need
very little routine attention or adjustment.
The Magnum SX series pumps have a

number of significant improvements over the
SM series they replaced. Back vanes on the
cast impeller keep the enlarged seal area free
of debris and turbulence inside the impeller
housing has been reduced by eliminating
internal bolt heads.
Four cast iron legs on the spur gear housing
make it easier to mount the complete assembly
securely in the correct location, while the
increased number of splines on the 32mm drive
shaft provides a high input power rating.
There are three models – SX1000 tractormounted, SX2000 engine-driven and SX2600
electric motor-driven – all capable of handling
up to 12% solids thanks to an effective
chopping action. Auto pressure regulation and
self-priming are optional.
The self-priming system includes a small
pump with mechanical, hydraulic or electric
drive, and a syphon on the suction side
protecting the vacuum pump. Any remaining
liquid automatically drains into the suction
stream as soon as the pump starts to deliver.
On the delivery side, a non-return valve is
closed during priming and opens automatically
when the pump gets going.
Such is the output potential of Bauer
Magnum SX pumps that contractors upgrading
to these units may need to invest in bigger
diameter hose to exploit the pumps’
performance potential in full
For couplings, there is no better choice than
Bauer HK, the original quick and secure
connection system for rigid and flexible mobile
pipes available in seven sizes for hoses or
pipes of 49mm to 194mm diameter.
Manufactured from hot-dipped galvanized
steel, the original Bauer coupling has no loose
parts and needs no tools, and with up to 30deg
articulation of the coupling joint, there is no
need for perfect alignment.
