4 Description of the Pump (Set)
16 of 56 Etanorm-RX
Design The pump is designed with an axial fluid inlet and a radial or tangential outlet. The
hydraulic system runs in its own bearings and is connected to the motor by a shaft
coupling.
Function The fluid enters the pump axially via the suction nozzle (6) and is accelerated
outward by the rotating impeller (7). In the flow passage of the pump casing the
kinetic energy of the fluid is converted into pressure energy. The fluid is pumped to
the discharge nozzle (2), where it leaves the pump. The clearance gap (1) prevents
any fluid from flowing back from the casing to the suction nozzle. At the rear side of
the impeller, the shaft (4) enters the casing via the casing cover (3). The shaft passage
through the cover is sealed to atmosphere with a shaft seal (8). The shaft runs in
rolling element bearings (9 and 10), which are supported by a bearing bracket (5)
linked with the pump casing and/or casing cover.
Sealing The pump is sealed by a shaft seal (KSB cartridge seal or gland packing).

For positioning, installing and operating sprinkler pumps, always comply with the
following fire protection standards and directives:
▪VdS CEA 4001
▪CEA 4001
▪EN 12845
▪NFPA 20
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
Always install the pump set in a horizontal position.
5.3.1 Installation on the foundation
L1

Fig.7: Fitting the shims
L Bolt-to-bolt distance 1 Shim
2 Shim if (1) > 800 mm 3 Foundation bolt
üThe foundation has the required strength and characteristics.
üThe foundation has been prepared in accordance with the dimensions given in
the outline drawing/general arrangement drawing.
1. Position the pump set on the foundation and level it with the help of a spirit
level placed on the shaft and discharge nozzle.
Permissible deviation 0.2 mm/m.
2. Use shims (1) for height compensation, if necessary.
Always fit shims, if any, immediately to the left and right of the foundation
bolts (3) between the baseplate/foundation frame and the foundation.

5 Installation at Site
18 of 56 Etanorm-RX
For a bolt-to-bolt distance (L) > 800 mm fit additional shims (2) halfway between
the bolt holes.
All shims must lie perfectly flush.
3. Insert the foundation bolts (3) into the holes provided.
4. Use concrete to set the foundation bolts (3) into the foundation.
5. Wait until the concrete has set firmly, then level the baseplate.
6. Tighten the foundation bolts (3) evenly and firmly.
7. Grout the baseplate using low-shrinkage concrete with a standard particle size
and a water/cement ratio of ≤ 0.5.
Produce flowability with the help of a solvent.
Perform secondary treatment of the concrete to DIN 1045.
NOTE
For low-noise operation contact KSB to check whether the pump set can be
installed on anti-vibration mounts.
(Only if permitted in accordance with the fire protection directives!)
NOTE
Expansion joints can be fitted between the pump and the suction/discharge line.
(Only if permitted in accordance with the fire protection directives!)
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 pipelines in close proximity to the pump and connect them without
transmitting any stresses or strains.
▷Observe the permissible forces and moments at the pump nozzles.
▷Take appropriate measures to compensate 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.

Etanorm-RX
NOTE
VdS-certified pumps must be connected in compliance with the current VdS CEA
4001 regulations.
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 equal to or greater than the nominal
diameters of the pump nozzles.
The nominal diameter of the suction line shall be in compliance with VdS form
3003. The installation of check and shut-off valves is also defined by VdS form
3003.
üTo prevent excessive pressure losses, adapters to larger diameters must be in
accordance with the fire protection directives.
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.
▷Observe the information in (ðSection7.2.2.2,Page31) .
3. Check that the inside of the pump is free from any foreign objects. Remove any
foreign objects.
4. If required, install a filter in the piping (see drawing: Filter in the piping).
Observe the regulations laid down in the fire protection directives!

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.
5. 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.

The following condition must be met:
∑IFVI, ∑IFHI, and ∑IMtI are the sums of the absolute values of the respective loads
acting on the nozzles. Neither the load direction nor the load distribution among the

DANGER
Risk of potentially explosive atmosphere by mixing of incompatible fluids in the
auxiliary piping
Risk of burns!
Explosion hazard!
▷Make sure that the barrier fluid and quench liquid are compatible with the
fluid pumped.
