(sliding frame and discharge and pre-pressing screw for feeding a thick matter pump). Depending on the
Depending on the customised system
assemblies such as an assembly platform
insulation/heating or instrumentation are added

Functional description and design features
A sliding frame made of a bevelled special profile is moved back and forth over the flat silo floor by a hydraulic cylinder
back and forth over the flat silo floor. During the forward movement
the inclined profile edge underruns the material
which is conveyed to the discharge screw
is conveyed to the discharge auger by the driving edge. The sliding frame supports the even and complete
complete sludge discharge into the silo discharge screw and prevents bridging of the medium. Due to the
The even lowering of the silo contents ensures that the sludge is discharged as in a mass flow (first in
first out)
and segregation is prevented
The necessary projection for the drive is approx. 2.80 metres
The lifting speed of the discharge sliding frame can be infinitely adjusted manually to optimise the operating behaviour
operating behaviour. A stuffing box seal and (optional) automatic centralised grease lubrication ensure that the system is sealed against the conveyed material
of the system against the conveyed material
The PDSL series is price-optimised
Installation in rectangular or square steel silo with flat base
Silo dimensions (lxw): 5,500 x 3,500 mm
Cylinder stroke: 800 mm
Weight of the frame: 1.2 tonnes
The silo discharge system consists of
Discharge sliding frame made of special profile S 355
in two or three sections depending on size for transport and easy assembly
with bolted connection
Double-acting hydraulic cylinder
short design
with coupling rod (multiple chrome-plated)
clamping coupling
clamping flange and driver
Spherical cap for aligning the hydraulic cylinder during assembly
Special seals and guide bands as well as contact protection for coupling rod
Two non-contact limit switches on the hydraulic cylinder for stroke reversal
Blockage monitoring
Automatic centralised grease lubrication via the thick matter pump lubrication system
Electrical and hydraulic controls
Safety devices
The proper functioning of the discharge sliding frame is monitored by non-contact limit switches and control of the lifting time
and control of the lifting time. If the set lifting time is exceeded
the lift reverses automatically and a fault signal is issued
(without interrupting operation)
The hydraulic circuit is pressure-monitored. In the event of a blockage of the discharge sliding frame
the stroke is reversed automatically
stroke reversal takes place automatically
When planning
please consider the space required for the hydraulic cylinder outside the silo as well as a free space for removal
for removal

A gate valve can be used to shut off parts of a system for a variety of reasons. The
gate valve is installed either under a silo
bunker etc. in the inlet of the Putzmeister pump
This is advantageous for carrying out any maintenance work in the pump hopper when the silo is full
