1. Introduction
CLP 674 / CLP D 674 pumps are specic designed
for various chemicals, liquids, additives and other
hard-to-handle uids in production systems,
placed in subsea, onshore and oshore applications.
Danfoss CLP pumps are based on the axial piston
principle oering long life and high eciency in
the demanding oil and gas industry. The Danfoss
CLP pumps have a light and compact design,
resulting in one of the smallest footprints on the
market.
All parts are designed to provide long service
life, i.e. long service life with a constantly high
eciency and minimum of service required.
Lubrication of the moving parts in the pumps is
This datasheet covers CLP 674, CLP D 674-025058 / 085-152 / 140-500. In the next pages all
pumps will be named as CLP.
The CLP 674 and CLP D 674 pumps are all
engineered according to API 674. The CLP pumps
provided by the uid itself. No oil lubrication is
thus required.
The pumps are xed displacement pumps in
which the ow is proportional to the number of
revolutions of the input shaft and the pump
displacement, regardless of any counterpressure.
The pump design ensures a minimal acceleration
loss and low pulsation.
If magnetic drive is required, please
contact Danfoss High Pressure Pumps
sales organization for further information.
are made in AISI 316, whereas the CLP D are made
in Super Duplex / Duplex.

2. Benets
• High reliability:
• Constructed to provide maximum
reliability.
• Designed for a wide range of corrosive,
volatile and other hard-to-handle
uids.
• All parts are made of high-grade
materials.
• Minimum service required:
• Generates insignicant pulsations in
the discharge line.
• No oil lubrication is required.
• Long service life and easy maintenance.
• Low energy costs:
• The highly ecient axial piston design
provides the lowest energy consumption
of any comparable on the market.
• Zero risk of lubricant contamination:
• Oil lubricants are replaced with the
pumped medium so there is no
contamination risk from the pump.
3. Application examples • Dehydration / glycol pumping
• Transfer pumps
• Produced water injection
• Wash water system
• Chemical / technical processes
• Water make up pump
• Easy installation:
• One of the smallest, lightest and most
compact designs available in the
market.
• Pump can be installed horizontally or
vertically.
• In most cases no pulsation dampeners
are necessary due to extremely low
pulsations.
• Powered by electric motors or
combustion engines.
• Certied quality:
• ATEX available on request.
• CE available.
• Type approval available.
• Design verication available on
request.
• The pump is designed according to API
674.
• Gas sweeting – “Amine”
• Water and glycol hydraulic uid
• Subsea
• Closed and open drain pump
• Seal ush pump

6. Motor requirements
The required motor power can be calculated by
using the following equation:
n x V x p
P =
600.000 x η
P: Power (kW)
M: Torque (Nm)
η: Mechanical eciency
p: Pressure (barg)
n: Motor speed (rpm)
V: Displacement (cm
3
/rev.)
From the ow curves in section 5, you can
determine the rpm of the pump at the desired ow.
The required torque is calculated as follows:
V x p
M =
62.8 x η
To determine the correct motor size, both the
power and torque requirement must be veried.

pump at 80 barg (1,160 psig)

7.1 Filtration
As many chemicals have very low viscosity,
the CLP pumps have been designed with
very narrow clearance in order to control internal
leakage rates and improve component performance. Therefore it is important that the inlet
liquid is ltered properly to minimize the wear of
the pump.
The main lter must have a ltration eciency of
99.98% at 10 μm. We recommend that you use
precision depth lter cartridges rated 10 μm abs.
β
5000 (equivalent to a ltration eciency of
10 ≥
99.98%). Bag lters and string wound lter
cartridges typically have only 90% ltration
eciency. This means that for each 100,000
particles reaching the lter, 10,000 particles pass
through it compared to only 20 particles in a
lter with an eciency of 99.98%.
For more information on the importance of
proper ltration, please consult our publication
“Filtration” (code number 521B1009), which also
will provide you with an explanation of ltration
denitions and a guidance on how to select the
right lter.
7.2 Noise
Since the pump unit is mounted on a frame, 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 dampeners and to use exible hoses
rather than metal pipes where possible.
The noise level is inuenced by:
• Pump speed:
High rpm makes more uid/structureborne pulsations/vibrations than low rpm.
• Discharge pressure:
High pressures make more noise than low
pressures.
• Pump mounting:
Rigid mounting makes more noise than
exible mounting because of the structureborne vibrations. Be sure to use dampeners
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 (VFDs):
Motors regulated by VFDs can produce
more noise if the VFD does not have the
right settings.
7.3 Preferred design
Purpose of valve “V-1” and “V-2”:
Isolation valves, which make it possible to drain
the pump before servicing.
Purpose of valve “V-3”
Safety/relief valve, this valve must protect the
pump against too high inlet pressure. Too high
inlet pressure can be caused by:
• The pump is rotating in the wrong direction.
• A situation where valve V-1 is closed, valve
V-2 is open and V-5 is leaking.
Purpose of valve “V-4”:
Safety/relief valve, this valve must protect the
pump against too high outlet pressure. Too high
outlet pressure can be caused by:
• A situation where V-2 is closed.
• Check valve V-5 has been mounted in the
wrong direction.
The V-4 setting has to be 10% above the
maximum system pressure. The electric motor
must be designed for this pressure.

Data sheet CLP 674 / CLP D 674
8. Service
Purpose of “V-5”:
Check valve, this valve prevents the ow from
running reverse into the pump when connected
to a multipump system.
Purpose of “V-6”:
Bleed valve, this valve removes air from the
pump and pipes.
Purpose of “V-7” and “V-8”:
Drain valves, those valves help to empty the
pump and pipes for uid prior to service.
Danfoss CLP pumps are designed for long
periods of service-free operation to ensure
low maintenance and life cycle costs. Provided
that the pump is installed and operated
according to Danfoss specications, Danfoss CLP
pumps typically run 1 year between service.
However, the service schedule for your Danfoss
CLP pump may vary according to the application
and other factors.
The life of a pump may be greatly shortened if
Danfoss recommendations concerning system
design and operation are not followed.
Purpose of “PAL”:
Pressure alarm low, this projects the pump from
running dry.
Purpose of “TAH 1-3”:
Temperature alarm high, this protects the pump
from too high inlet media temperature.
Purpose of “TAH 1-4”:
Temperature alarm high, this protects the pump
from running hot due to over pressure or the
pump running dry.
8.1 Spare parts
The following spare parts kits are available for
the CLP pumps.
O-ring and screw set
Shaft seal set
Cylinder barrel
Valve plate set
Retainer set
Piston set
In our experience, poor filtration is the number
one cause of pump damage.
Other factors that aect pump performance and
lifetime include:
• running the pump at speeds outside
specications.
• supplying the pump with water at
temperatures higher than recommended.
• running the pump at inlet pressures
outside specications.
• running the pump at outlet pressures
outside the specications.
We recommend that you inspect your pump
after 1 year of operation even if it is running
without any noticeable problems. Replace any
worn parts if necessary, including pistons and
shaft seals, to keep your pump running eciently and to prevent breakdown. If worn parts
are not replaced, then our guidelines recommend more frequent inspection.
If your pump is running continuously under
“high end performance” conditions we recommend that you inspect your pump after half a
year of operation, replacing worn parts if
necessary.
8.2 Spare part suitcase
Danfoss High Pressure Pumps can provide a
spare part suitcase containing all necessary parts
and instructions for overhaul of CLP pumps.
The suitcase can at any time be returned for rell
of consumed parts.
Contact Danfoss High Pressure Pumps for price
and availability of the spare part suitcase.
