Design The horizontal multistage centrifugal pump is designed for handling clean or slightly
aggressive fluids containing water. The pump is easy to install, commission and
operate. The hydraulic assembly is driven by an electric motor. All hydraulic system
components of the pump are made of stainless steel. The pump casings are available
in stainless steel or cast iron.
The pump is suitable for transporting cold and warm water and boosting the
pressure thereof without any wear on the components within the specified operating
range. Fluids whose viscosity or density differ from water can also be transported. In
this case, a motor with adjusted rating might be required.
The pump is designed with openings for measuring, draining and venting. These
openings are closed with screw plugs. Connection (5) serves to fill and vent the pump
or measure the inlet pressure and suction pressure using a G1/4 connection.
Connection (6) serves to drain the pump or measure the discharge pressure using a
G1/4 connection.
Function The rotating impeller causes the pressure to drop at the impeller inlet. This pressure
drop makes the fluid enter the suction nozzle (1). Each stage (2) consists of an
impeller and a diffuser. The flow rate of the pump is determined by the free passage
of the stage. The pressure at the stage depends on the impeller diameter. Given the

4 Description of the Pump (Set)
16 of 36 Comeo
modular design system, the number of impellers can be selected to ideally match the
required duty point. After the fluid has left the last impeller, it is guided back
through the pump in the passage between the pump stages and the pump casing (3)
and leaves the pump at the discharge nozzle (4).
Sealing The pump is sealed by a standardised mechanical seal.
4.6 Noise characteristics
The noise characteristics given refer to the motor. See motor literature supplied.
4.7 Scope of supply
Depending on the model, the following items are included in the scope of supply:
▪Pump

all wetted components.
▷Observe the data given in the order confirmation.
5.2 Checks to be carried out prior to installation
Place of installation
WARNING
Installation on mounting surface which is unsecured and cannot support the load
Personal injury and damage to property!
▷Use a concrete of compressive strength class C12/15 which meets the
requirements of exposure class XC1 to EN206-1.
▷The mounting surface must have set and must be completely horizontal and
even.
▷Observe the weights indicated.
1. Check the structural requirements.
All structural work required must have been prepared in accordance with the
dimensions stated in the outline drawing/general arrangement drawing.
5.3 Installing the pump set
CAUTION
Ingress of leakage into the motor
Damage to the pump!
▷Never install the pump set with the "motor below".
1. Install and fasten the pump set on a sturdy and level foundation in a dry, frost-
proof room.
2. Make sure that sufficient air can reach the fan opening of the motor.
(The clearance above the fan opening must measure at least 1/4 of the diameter
of the fan cover air intake.)
3. Place a spirit level on the discharge nozzle to align the pump set.

5.4 Piping
5.4.1 Connecting the piping
DANGER
Impermissible loads acting on the pump nozzles
Danger to life from leakage of hot, toxic, corrosive or flammable fluids!
▷Do not use the pump as an anchorage point for the piping.
▷Anchor the pipes in close proximity to the pump and connect them properly
without transmitting any stresses or strains.
▷Take appropriate measures to compensate for thermal expansion of the piping.
CAUTION
Incorrect earthing during welding work at the piping
Destruction of rolling element bearings (pitting effect)!
▷Never earth the electric welding equipment on the pump or baseplate.
▷Prevent current flowing through the rolling element bearings.
NOTE
Installing check and shut-off elements in the system is recommended, depending on
the type of plant and pump. However, such elements must not obstruct proper
drainage or hinder disassembly of the pump.
NOTE
VdS-certified pumps must be connected in compliance with current information
from VdS CEA 4001.
üThe suction lift line has been laid with a rising slope, the suction head line with a
downward slope towards the pump.
üA flow stabilisation section having a length equivalent to at least twice the
diameter of the suction flange has been provided upstream of the suction flange.
üThe nominal diameters of the pipelines are at least equal to the nominal
diameters of the pump nozzles.
As far as the nominal diameters in the suction and discharge line, and installation
of check valves and shut-off elements in a fire protection system are concerned,
observe the sizing specifications in the relevant directives.
üAdapters to larger nominal diameters are designed with a diffuser angle of
approx. 8° to avoid excessive pressure losses.
üThe pipelines have been anchored in close proximity to the pump and connected
without transmitting any stresses or strains.
1. Thoroughly clean, flush and blow through all vessels, pipelines and connections
(especially of new installations).
2. Before installing the pump in the piping, remove the flange covers on the
suction and discharge nozzles of the pump.
CAUTION
Welding beads, scale and other impurities in the piping
Damage to the pump!
▷Remove any impurities from the piping.
▷If necessary, install a filter.

NOTE
Use a filter with laid-in wire mesh of 0.5 mm x 0.25 mm (mesh size x wire diameter)
made of corrosion-resistant material.
Use a filter with a filter area three times the cross-section of the piping.
Conical filters have proved suitable.
4. Connect the pump nozzles to the piping.
CAUTION
Aggressive flushing and pickling agents
Damage to the pump!
▷Match the cleaning operation mode and duration for flushing and pickling
service to the casing and seal materials used.
5.5 Fitting a bypass
NOTE
If the pump is operated against a closed valve, installing a bypass is recommended.
The bypass capacity must correspond to at least 10 % of the optimum volume flow
rate.
5.6 Electrical system
5.6.1 Information for planning the electrical connection
Rated current
The permissible rated current of the motor is shown on the motor name plate. It
indicates the operating range of the motor. The motor protection switch can be pre-
set to this value to protect the motor. By measuring the actual current of the pump
during operation the motor protection switch can be pre-set to a specific value for
protecting the pump/motor combination. This current value can also be used to select
appropriate electrical equipment such as drives with frequency inverter, master
switch, conductor diameter, etc.
