Pump
The TEMEKNA Pump is a high-speed screw feeder
which is installed as feeding unit in front of a pneumatic
conveying pipeline. This pneumatic conveying system can be
designed as conventional pneumatic pipeline system or as
TEMEKNA pipeline system.
The task of the Pump is to feed a defined solids mass flow
into the conveying gas flow against the overpressure in the
conveyor pipe, while at the same time sealing the system
overpressure against the surrounding or the upstream
sections of the plant to keep the gas leakage through the
feeder as low as possible.
This sealing is realized by forming a plug of bulk solids of
defined length at the end of the screw.
Conveying pressures up to approx. 2.5 bar overpressure, in
special cases even higher, as well as conveying distances of
up to approx. 1000 m and throughput capacities of up to
approx. 400 t/h are achieved. It is possible to convey
pulverized bulk solids as well as coarser materials with grain
sizes up to approx. 10 mm. The Pump can be used as a
feeder for dense-phase as well as for lean-phase
conveyance.
Advantages of TEMEKNA Pump
● Non-contact between screw / housing leads to less
wear and high operation reliability
● Only end wing has to be exchanged not complete
screw
● Flexible partial load operation due to sided bearing
system
● No balancing of screw needed
● High sealing effect due to small gap between screw
and wear bushing
● Non-contact labyrinth sealing ideal for higher screw
speed
● Low maintenance costs and time
● Pump designed for non explosive or explosive
bulk materials like coal dust
● 100% feeding / transport of
explosive bulk materials
Main Components of Pump
1. Material inlet
2. Surge bin with dedusting socket
3. Conveying and compressing screw
4. Material discharge area
5. Double sided sealing and bearing
system
6. Material / Gas mixing chamber
7. Conveying gas inlet
8. Conveying pipe connection
Summary
The TEMEKNA solid Pump is a very compact unit due
to the two-sided bearing. The machinery runs extremely quiet
and is characterized by very low power consumption and
reduced pulsation during operation. The wear parts can be
easily replaced, and the pump is suitable for a very wide
range of applications and materials.
To sum it up it can be said that the Claudius Peters Pump
is an excellent bulk feeding system for safety operation
processes with highest plant reliability.
