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.
1: Shaft sealing
2: Port flange
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)
report available on request.
- IATF 16949, ISO 9001, ISO 14001.
• High pressure reverse osmosis
• Zero liquid discharge (ZLD)
• Minimal liquid discharge (MLD)

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
