5 Pump Introduction
5.1 Model key
Table 5: Model key Example DPVCI 15/17(19) B
5.2 Description of the product
The vertical, immersible multi stage centrifugal pump
series are designed for pumping liquids for machine
tools, condensate transfer, liquid transfer in industrial
washing machines and similar applications.
The hydraulic assembly is driven by an electric motor.
WARNING
The pump must not be used to transfer
inflammable liquids such as diesel oil
and petrol.
5.3 Ecodesign
Product information according to Regulation 547/
2012 and Directive 2009/125/EC "Ecodesign
Directieve" (water pumps with maximum shaft power
rating of 150 kW, applies only to water pumps marked
with the Minimum Efficiency Index MEI, see pump
nameplate):
•Minimum Efficiency Index: See nameplate,
legend for nameplate. See table 1: Description
sticker.
•The reference value MEI of a water pump with
the best efficiency is = 0.70.
•Year built: See nameplate, legend for
nameplate. See table1: Description sticker.
•Manufacturer's name or trademark, official
registration number and place of production:
See manual or order documentation.
•Information about type and size of the item: See
table 1: Description sticker.
•Performance curves of the pump, including
efficiency characteristics: See documented
curve.
•The efficiency of a pump with a corrected
impeller is usually lower than that of a pump
impeller with a full diameter. A pump with a
corrected impeller is adapted to a certain duty
point, thereby reducing the energy consumption.
Minimum Efficiency Index (MEI) refers to the full
impeller diameter.
•The operation of this water pump at different
operating points can be more efficient and more
economical when it is controlled, for example
using a variable speed controller which adjusts
the pump operation to the system.
•Information for disassembly, recycling or
disposal after the final shutdown: See sub
chapter 4.6.3: Dismantling.
•Information about the efficiency reference value
or MEI = 0.7 (0.4) benchmark index for the pump
on the basis of the pattern in the picture, please
visit: http://www.europump.org/efficiencycharts.
5.4 Modular selection
To suit almost every application the pump is
assembled out of modules which can be selected
depending on the required working range.
Basic modules are:

•Basic pump model, which defines the capacity,
pressure and basic material
•Sealings, which define the elastomers, the
mechanical seal and the shaft seal type.
•Electric motor, which defines all requirements
of the motor such as motor size, power, voltage,
frequency and all possible motor accessories.
5.5 Operation
During centrifugal operation of the pump an negative
pressure is created at the inlet of the impeller. This
underpressure enables the medium to enter the pump
at the suction connection (A).
A stage (B) consists of an impeller and diffuser or an
empty stage. The passage of this stage determines
the capacity of the pump. The diameter of the stages
is related to the centrifugal forces and its “stage
pressure”: the more stages, the more pressure.
This total capacity and raised pressure will be guided
to the discharge connection (C) of the pump.
ATTENTION
Check the seal. Turn the shaft every
three months and just before putting
into operation.
5.6 Measuring, draining and
venting
The pump is provided with plugs for measuring,
venting and to fill the container.
Connection (F) is meant to measure the discharge
pressure using a G ¼ connection.
Connections (F) are meant to vent the pump system
when the pump is not in operation. Or to measure the
discharge pressure of the pump using a G 1/4
connection or to (re)fill the container.
5.7 Working range
The working range depends on the application and a
combination of pressure and temperature. For
specific and detailed limits advice the working ranges
are described in the chapter 5.4: Modular selection.
The overall working range of the pumps can be
summarised as follows:

7 Installation instructions
7.1 Pump location
WARNING
The pump must be installed so that
persons cannot accidentally come into
contact with hot surfaces.
The pump is designed for tank mounting in vertical
position. The pump is positioned in a hole cut into the
cover of the tank (upper side) and is secured to the
tank by four hexagon head screws through the holes
in the mounting flange. It is recommended to fit a
sealing gasket between the pump flange and tank.
7.2 Installation dimensions
Table 9: DPVCI 2-15 B / 15 C
7.3 Setting up the pump
ATTENTION
Pumps which do not stand steady or
stable on their own, should be mounted
on a rigid and stable base.
ATTENTION
Locate the pump at the place with the
lowest risk for noise nuisance.
1. Place and install the pump on a level, stable
surface in a vertical position with the motor on
top. Make sure the pump is always mounted with
a gasket on the top of the reservoir.
2. Make sure that sufficient air can reach the
cooling fan of the motor. For this purpose the
free space above the cooling fan should be at
least 1/4 of the diameter of the fan cover air
intake.
3. It is advised to install a valve on the discharge
connection of the pump.
4. To avoid medium flowing back through the
pump, when idle, make sure a non-return valve
is installed and the inlet is always under liquid
level.
5. Make sure that the inlet of the pump is never
clogged.

7.3.1 Indicators
The arrow on the motor stool indicates the rotating
direction of the motor.
7.3.2 Install bypass
Install a bypass if the pump operates against a closed
valve. The required capacity of the bypass is at least
10 % of the optimum volume flow. At high operating
temperatures a higher volume flow is required. Refer
to the table "Minimum volume flows" in the paragraph
"Working range".
7.3.3 Permissible forces and moments at the
pump nozzles
No piping-induced forces and moments (from warped
pipelines or thermal expansion, for example) must act
on the pump.
7.4 Check seal
Make sure the shaft (210) and cartridge ring (500) is
in the lower position. The coupling bolts (914.01)
should not be tightened.

Then fasten the grub screws (904) firmly (3X).
Lift the coupling, distance between seal cover (471)
and cartridge ring (500) should be 1.5 mm1. Tighten
the coupling bolts (914.01)crosswise according to
table 10: Torques
7.5 Mounting a motor on the
pump
ATTENTION
It is advised to use a specially designed
DP-Pumps motor. Before installing an
other brand/standard IEC-standard
motor, DP-Pumps has to be consulted
to verify the applicability.
The motor has to conform to the following conditions:
•Reinforced bearing at driven end (to withstand
the axial force)
•Axially fixed rotor (to minimize the axial play of
the pumps hydraulic)
•Smooth shaft, no key lock (to improve the
coupling grip and to improve the motor balance)
•Align the motor on the motor stool
•Fit hexagon head bolts (901.04) and tighten the
bolts
•Install coupling (862)
•Fit hexagon socket head cap screws (914.01)
•Install coupling (861)
•Fit hexagon socket head cap screws (914.05)

7.7 Commissioning
WARNING
Pay attention to the direction of the vent
hole and take care to ensure that the
escaping water does not cause injury to
persons or damage to the motor or
other components.
7.7.1 Before starting the pump, be sure:
•that all pipe connections are tight;
•that the pump body is partly filled with liquid
(partly submerged) see figure 7: DPVCI 2-15 B /
15 C;
• that the strainer is not blocked.
7.7.2 Start the pump as follows:
•Close the isolating valve on the discharge side
of the pump;
•If the pump is fitted with a vent valve, this valve
must be opened;
•See the correct direction of rotation of the pump
on the motor fan cover or on the coupling guard;
•When seen from the top, the pump should rotate
clockwise;
•Start the pump and check the direction of
rotation;
•Open the discharge isolating valve a little;
•If the pump is fitted with a vent valve, closed the
valve until the pump is completely vented;
•Completely open the discharge isolating valve.
The pump has now been vented and is ready for
operation.
ATTENTION
The pump is not allowed to run against
a closed discharge valve.
ATTENTION
Seen from the top of the motor the
pump should rotate clockwise. See
7.3.1: Indicators (B). In case of a 3-
phase motor the rotating direction can
be changed by exchanging two of the
three phases.
ATTENTION
Make sure the pump and piping are
installed properly.
7.7.3 After an extended period of non-
operation or storage
During first start-up, check the mechanical seals for
leakage due to seizure or dehydration of the
lubricating film. If so, please proceed as following:
1. Turn shaft manually.
If the mechanical seal is leaking:
1. Disassemble the mechanical seal.
2. Thoroughly clean and decrease the running
surfaces.
3. Assemble the mechanical seal again and retry
start-up.
If this doesn’t solve the shaft leakage, replacement of
the mechanical seal is necessary.
