Basics for Hydrotransport
• Our customers handle and transport through pipes
heterogeneous, abrasive and corrosive media with a defined viscosity
• The Competing Systems are:
• train
• truck
• belt
• and comes to pipelines – centrifugal pumps

Displacement vs. Centrifugal Pumps
• Centrifugal Pumps
• use excess water to transport solids
# Dealing with the rescource WATER
# Excessive energy consumption due the excess WATER
• have a hydraulic efficiency of 70% (if new)
Double Hose-Diaphram Pumps have 97%
# energy consumption of PD pumps is 15-25% better
• due to up to 35 m/s impellers and wear plates are worn within 2000h
Double Hose-Diaphragm will stand 8000 h and more.
# cost for the parts, recycling cost, environm., CO2, (pro PD)
# operation safty and reliability (pro PD see Multisafe)

Displacement vs. Centrifugal Pumps
• Decission Process
• In case the question of the owner is:
„when do I have the first ROI“
– Centrifugal Slurry Pumps will be the choice
• In cases the question is:
„what is the total ROI for the livetime of the mine and equipment“
- the first choice in any case is the
Piston-Diaphragm-Pump

Evolution of Pumps- Hose-Diaphragm Pump -
• Hydrostatic Pressure by
surrounding hydraulic liquid
• Pressure inside and outside
the diaphragm is equal
• Hose-diaphragm is not
covering any pressure,
except for static load
• Medium in contact with
diaphragm only

Double Hose-Diaphragm Pumps - Working Principle -
Copyright FELUWA Pumpen GmbH
Copyright FELUWA Pumpen GmbH19
• Double safety due to two hose-diaphragms
• Hermetically sealing between medium,
hydraulic drive system and environment
• Linear flow path without deviations
• Less or no sedimentation
• No dead pockets
• Pump housing is never in contact with the medium
• Small and compact pump head
• Fast volume exchange in pump head
• High efficiency – high energy savings
Hydraulic Efficiency: > 97%
Overall Efficiency: > 85%

Double Hose-Diaphragm Pumps- Pressure sensor -
Foliennr.
• Pressure detection of the area in
between the two hose-diaphragms
• Normally pressure free
• Pressure increases if one diaphragm
fails
• Alarm is set if one hose-diaphragm
fails
• Pump operation can be continued
without any restriction until the
system allows for a shutdown and
repair.

Special Configurations- Double Valves -
Double Valves
• Double valves are used for critical processes, which do not allow an interrupted flow.
• Double valves provide double-safety against smallest leakages.
• Double valves reduce the wear of the valves and increase maintenance intervals.
