Data sheet | APP 0.6-46 / APP (W) 5.1-10.2 pumps
1. Introduction
This data sheet is valid for APP pumps both non
ATEX and ATEX certied. ATEX certied pumps
are indicated by Ex in the type designation example APP 0.6 Ex.
The Danfoss range of APP high-pressure pumps
is designed according to EN 809 for use in RO
applications with low viscosity and corrosive
uids such as:
• Sea water
• Brackish water
• Waste water (APP W)
1: Shaft sealing
2: Port ange
3: Bleeding plug
4: Retainer plate
5: Piston/shoe
6: Valve plate
7: Swash plate
8: Cylinder barrel
9: Springs
10: Port plate
11: Flushing valve
(not available on
APP 5.1-10. 2)
12: Housing
13: Tail stock screws
14: Drain plug
Danfoss APP pumps are positive displacement
pumps with axial pistons that move a xed
amount of water in each cycle. Flow is proportional to the number of input shaft revolutions
(rpm). Unlike centrifugal pumps, they produce
the same ow at a given speed no matter what
the discharge pressure.
Below sectional drawing is an example of an
APP pump. The sectional drawing for the specic
pump sizes are to be found in the pump
instruction.
2. Benets
• Zero risk of lubricant contamination:
- Oil lubricants are replaced with the
pumped medium, water, so there is no
contamination risk from the pump.
• Low maintenance costs:
- Ecient design and all-stainless steel
construction ensure exceptionally long
life. When Danfoss specications are
met, service intervals of 8,000 hours can
be expected. Service is easy, and can be
carried out on-site due to the simple
design and few parts.
• Low energy costs:
- The highly ecient axial piston design
provides the lowest energy
consumption of any comparable pump
on the market.
• Easy installation:
- The most compact and lightest design
available.
- The pump can be installed vertically
and horizontally.
- No pulsation dampeners necessary due
to extremely low pressure pulsation.
3. Application examples Danfoss APP pumps are built into a broad range
of RO desalination plants around the world:
• Containerized solutions for hotels, resorts
and residences on islands and in coastal
regions
- Powered directly by electric motors or
combustion engines (with special
coupling).
- All pumps except APP (W) 5.1 - 10.2 are
supplied with an integrated ushing
valve that allows the uid to ow
from inlet to the outlet, when the pump
is not running.
• High reliability:
- All parts are made of high corrosion
resistant materials e.g. Duplex
(EN1.4462/ UNS S31803) and
Super Duplex (EN1.4410/UNS S32750)
stainless steel and carbon reinforced
PEEK.
• Certied quality:
- Pumps available as ATEX certied.
- For other certications, please see data
sheets for APP S (all super duplex) and
APP S 674 (API).
- Positive Material Identication (PMI)
report available on request.
- IATF 16949, ISO 9001, ISO 14001.
• Mobile systems for humanitarian and
military organizations
• Onboard systems for ships and yachts
• Oshore platforms for the oil and gas
industry
• Municipal and regional waterworks

If the ow required and the rotation speed (rpm) of the
pump is known, it is easy to select the pump tting the
application best by using the diagrams below.
Furthermore, these diagrams shows that the
ow can be changed by changing the rotation
speed of the pump. The ow/rpm ratio is
constant, and the “required” ow can be
obtained by changing the rotation speed to a
corresponding value. Thus, the required rpm
can be determined as:
Required ow x Rated rpm
Required rpm =

9.1 Filtration
Proper ltration is crucial for the performance.
maintenance and warranty of your pump.
Protect your pump, and the application in which
it is installed, and by always ensuring that all
ltration specications are met, and by always
changing lter cartridges according to schedule.
Since water has very low vicosity, Danfoss APP
pumps have been designed with very narrow
clearances in order to control internal leakage
rates and improve component performance.
To minimize wear on the pump, it is therefore
essential to lter inlet water properly.
The main lter must have a ltration eciency
of 99.98% at 10 μm. We strongly recommend
that you always use precision depth lter
cartridges rated 10μm abs. ß
≥5000.
10
Please note that we do not recommend bag
lters or string-wound lter cartridges, which
typically have only 50% ltration eciency. This
means that out of the 100,000 particles that
enter such lters, 50,000 particles pass right
through; compare this to precision depth lters
that are 99.98% ecient, and only allow 20 of the
same 100,000 particles to pass through.
For more information on the importance of
proper ltration, including explanation of
ltration principles, denitions and guidance on
how to select the right lter for your pump,
please consult our Filtration information and
specications (Danfoss document number
521B1009).
Noise
Since the pump unit is typical mounted on a
frame or bell housing the overall noise level can
only be determined for a complete system. To
minimize vibrations and noise throughout the
system, it is therefore very important to mount
the pump unit correctly on a frame with
anti-vibration-dampeners, and to use exible
hoses rather than metal pipes where possible.
The noise level is inuenced by:
• Pump speed:
High rpm generates more uid/structure
borne pulsations/vibrations than low rpm,
because of higher frequency.
• Discharge pressure:
High pressure generates more noise than
low pressure.
• Pump mounting:
Rigid mounting generates more noise than
exible mounting, because of structureborne vibrations. Be sure to use dampers
when mounting.
• Connections to pump:
Pipes connected directly to the pump make
more noise than exible hoses, because of
structure-borne vibrations.
• Variable frequency drives (VFD):
Motors regulated by VFDs can produce
more noise if the VFD does not have the
right settings.
9.2 RO system with direct supply:
Inlet line:
a) Dimension the inlet line to obtain
minimum pressure loss (large ow,
minimum pipe length, minimum number
of bends/connections, and ttings with low
or no pressure losses). If relevant, please
consult “Parallel coupled pumps and
iSaves” (180R93549)
Inlet lter:
b) Install an inlet lter (1) in front of the APP
pump (2). Please consult section 9.1,
“Filtration” for guidance on how to select
the right lter. Thoroughly clean pipes and
ush system prior to start-up.
Low pressure relief valve:
c) Install a low pressure relief valve (9) in order
to avoid system or pump damage in case
the pump stops momentarily or is spinning
backwards.
Monitoring pressure switch:
d) Install a monitoring pressure switch (3)
between the lter (1) and the pump inlet.
Set the minimum inlet pressure according
to specications described in item 4 about
technical data. If the inlet pressure is lower
than the minimum pressure set, the
monitoring pressure switch must prevent
the pump from starting or from running.
Hoses:
e) Use exible hoses (4) to minimize
vibrations and noise. Please consult the
Danfoss Hoses and hose ttings data
sheet (521B0909) for guidance.
Inlet pressure:
f) In order to eliminate the risk of cavitation
and other pump damage, pump inlet
pressure must always be maintained
according to specications described in
item 4 about technical data.
Flushing valve:
g) For easy system lling and ushing, an
integrated ushing valve (6) is in
the APP pump (except APP (W) 5.1-10.2).
Non-return valve:
h) A non-return valve (7) in outlet can be
installed in order to avoid backspin of the
pump. The volume of water in the
membrane vessel works as an accumulator
and will send ow backwards in case of the
pump stops momentarily.

Data sheet | APP 0.6-46 / APP (W) 5.1-10.2 pumps
High pressure safety or relief valve:
i) As the Danfoss APP pump begins to create
pressure and ow immediately after
start-up and regardless of any counter
pressure, a safey or pressure relief valve (8)
should be installed after the non-return
valve to prevent system damage and to
avoid high pressure peaks.
Note: If a non-return valve is mounted in the inlet
line, a low-pressure relief valve is also required
between the non-return valve and
pump as protection against high-pressure peaks.

13. Service
Warranty
Danfoss APP pumps are designed for long
operation, low maintenance and reduced
lifecycle costs.
Provided that the pump has been running
according to the Danfoss specications, Danfoss
guarantees 8,000 hours service-free operation,
however, max. 18 months from date of
production.
If Danfoss recommendations concerning
system-design are not followed, it will strongly
inuence the life of the APP pumps.
Other factors that aect pump performance and
lifetime include:
- Running the pump at speed outside
specications.
- Supplying the pump with water at
temperature higher than recommended.
- Running the pump at inlet pressure outside
specications.
- Running the pump at outlet pressure
outside the specications.
Maintenance
Periodic inspections are required to ensure worn
parts (if any), are replaced in due time. Operational conditions such as water quality should be
taken into consideration when determining the
frequency of the inspections. Danfoss recommends yearly inspections.
It is recommended to order the purposedesigned tool kit.
Pump shutdown:
The APP pumps are made of Duplex/Super
Duplex materials with excellent corrosion
properties. It is, however, always recommended
to ush the pump with freshwater when the
system is shut down.
When stopping the pump for more than 1 day
ush the pump with permeate by rotating the
pump for 10 sec. Flushing through the ushing
valve of the pump without rotating the pump is
not enough for cleaning the inside of the pump.
The pump can be ushed with biocide like the
membranes. The biocide must be compatible
with the materials used in our pumps.
Repair assistance
In case of irregular function of the APP pump,
please contact Danfoss High Pressure Pumps.
