Basics for Hydrotransport


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

• 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


• 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 Pump


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.
