Data sheet | APP W HC 15 -30
1. Introduction
This data sheet is valid for APP W HC pumps.
The Danfoss range of APP W HC high-pressure
pumps is designed according to EN 809 for use in
water applications like:
• High pressure RO
• Zero liquid discharge (ZLD)
• Minimal liquid discharge (MLD)
•
Danfoss APP pumps are positive displacement
pumps with axial pistons that move a fixed
amount of water in each cycle.

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
Flow is propor tional to the number of input shaft
revolutions (rpm). Unlike centrifugal pumps, they
produce
the same flow 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 specific
pump sizes are to be found in the pump
instruction.
2. Benefits
3. Application examples
• 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:
- Efficient design and all-stainless steel
construction ensure exceptionally long
life. When Danfoss specifications are
met, service inspections 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 efficient 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.
Danfoss APP pumps are designed or use in a
broad range of plants around the world for:
- Powered directly by electric motors or
combustion engines (with special
coupling).
- All pumps are supplied with an
integrated flushing valve that allows the
fluid to flow 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.
• Certified quality:
- Positive Material Identification (PMI)

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

9.1 Filtration
Proper filtration 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
filtration specifications are met, and by always
changing filter 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 filter inlet water properly.
The main filter must have a filtration efficiency
of 99.98% at 10 μm. We strongly recommend
that you always use precision depth filter
cartridges rated 10μm abs. ß
≥5000.
10
Please note that we do not recommend bag
filters or string-wound filter cartridges, which
typically have only 50% filtration efficiency. This
means that out of the 100,000 particles that
enter such filters, 50,000 particles pass right
through; compare this to precision depth filters
that are 99.98% efficient, and only allow 20 of the
same 100,000 particles to pass through.
For more information on the importance of
proper filtration, including explanation of
filtration principles, definitions and guidance on
how to select the right filter for your pump,
please consult our Filtration information and
specifications (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 flexible
hoses rather than metal pipes where possible.
• Variable frequency drives (VFD):
Motors regulated by VFDs can produce
more noise if the VFD does not have the
right settings.
9.2 System with direct supply:
Inlet line:
a) Dimension the inlet line to obtain
minimum pressure loss (large flow,
minimum pipe length, minimum number
of b ends/connections, and fittings with low
or no pressure losses). If relevant, please
consult “Parallel coupled pumps and
iSaves” (180R93549
Inlet filter:
b) Install an inlet filter (1) in front of the APP
pump (2). Please consult section 9.1,
“Filtration” for guidance on how to select
the right filter. Thoroughly clean pipes and
flush 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 filter (1) and the pump inlet.
Set the minimum inlet pressure according
to specifications 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 flexible hoses (4) to minimize
vibrations and noise.
Inlet pressure:
f) In order to eliminate the risk of cavitation
and other pump damage, pump inlet
pressure must always be maintained
according to specifications described in
item 4 about technical data.
The noise level is influenced by:
• Pump speed:
High rpm generates more fluid/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
flexible 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 flexible hoses, because of
structure-borne vibrations.
AI283147317727en-000601 | 102019
Flushing valve:
g) For easy system filling and flushing, an
integrated flushing valve (6) is in
the APP pump.
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 flow backwards in case of the
pump stops momentarily.
9
Data sheet | APP W HC 15 -30
High pressure safety or relief valve:
i) As the Danfoss APP pump begins to create
pressure and flow 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.

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 W HC pumps are made of Duplex/Super
Duplex materials with excellent corrosion
properties. It is, however, always recommended
to flush the pump with freshwater when the
system is shut down.
Repair assistance
In case of irregular function of the APP W HC
pump, please contact Danfoss High Pressure
Pumps.
If Danfoss recommendations concerning
system-design are not followed, it will strongly
influence the life of the APP pumps.
Other factors that affect pump performance and
lifetime include:
- Running the pump at speed outside
specifications.
- Supplying the pump with water at
temperature higher than recommended.
- Running the pump at inlet pressure outside
specifications.
- Running the pump at outlet pressure
outside the specifications.
