2 Safety
10 of 66 Etanorm SYT

Only pumps/pump sets marked as explosion-proof and identified as such in the data
sheet may be used in potentially explosive atmospheres.
Special conditions apply to the operation of explosion-proof pump sets to EC
Directive 94/9/EC (ATEX).
Especially adhere to the sections in this manual marked with the Ex symbol and the
following sections (⇨ Section 2.10.1 Page 11) to (⇨ Section 2.10.4 Page 12).
The explosion-proof status of the pump set is only assured if the pump set is used in
accordance with its intended use.
Never operate the pump (set) outside the limits stated in the data sheet and on the
name plate.
Prevent impermissible modes of operation at all times.
2.10.1 Marking
The marking on the pump refers to the pump only.
Example of such marking: II 2 G c TX
Refer to the Temperature limits table for the temperatures permitted for the
individual pump variants. (⇨ Section 2.10.2 Page 11)
An EC manufacturer's declaration is required for the shaft coupling; the shaft
coupling must be marked accordingly.
The motor must be considered separately.
2.10.2 Temperature limits
In normal pump operation, the highest temperatures are to be expected on the
surface of the pump casing, at the shaft seal and in the bearing areas.
The surface temperature at the pump casing corresponds to the temperature of the
fluid handled. If the pump is heated, the operator of the system is responsible for
observing the specified temperature classes and fluid temperature (operating
temperature).
The table below lists the temperature classes and the resulting theoretical
temperature limits of the fluid handled. (A possible temperature rise in the shaft seal
area has already been taken into account).
The temperature class specifies the maximum permissible temperature at the surface
of the pump set during operation. For the permissible operating temperature of the
pump in question refer to the data sheet.
Table 4: Temperature limits
Temperature class as per EN 13463-1 Maximum permissible fluid
temperature
T1 Temperature limit of the pump
T2 280 ℃
T3 185 ℃
T4 120 ℃
T5 85 ℃
T6 Only after consultation
with the manufacturer
In the following cases, and if ambient temperatures are higher, contact the
manufacturer.
Compliance with temperature class T5 is warranted for the area of the rolling
element bearings based on an ambient temperature of 40°C, assuming that the
pump set is properly serviced and operated and that the surfaces in the bearing area
are freely exposed to the atmosphere.
If temperature class T6 has to be complied with, special measures may have to be
taken with regard to the bearing temperatures.
Misuse, malfunctions or non-compliance with the instructions may result in
substantially higher temperatures.

If the pump is to be operated at a higher temperature, the data sheet is missing or if
the pump is part of a pool of pumps, contact KSB for the maximum permissible
operating temperature.
2.10.3 Monitoring equipment
The pump (set) must only be operated within the limits specified in the data sheet
and on the name plate.
If the system operator cannot warrant compliance with these operating limits,
appropriate monitoring devices must be used.
Check whether monitoring equipment is required to ensure that the pump set
functions properly.
Contact KSB for further information on monitoring equipment.
2.10.4 Operating limits
The minimum flows indicated in (⇨ Section 6.2.3 Page 34) refer to water and water-
like liquids. Longer operating periods with these fluids and at the flow rates
indicated will not cause an additional increase in the temperatures on the pump
surface. However, if the physical properties of the fluids handled are different from
water, it is essential to check if an additional heat build-up may occur and if the
minimum flow rate must therefore be increased. The calculation formula in (⇨
Section 6.2.3 Page 34) can be used to check if an additional heat build-up may lead
to a hazardous temperature increase at the pump surface.

end
The pump is designed with an axial fluid inlet and a radial outlet. The hydraulic
system runs in its own bearings and is connected to the motor by a shaft coupling.
The fluid enters the pump axially via a suction nozzle (6) and is accelerated outward
in a cylindrical flow by the rotating impeller (7). The flow profile of the pump casing
converts the kinetic energy of the fluid 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 into the suction nozzle. The hydraulic
system is closed with a casing cover (3) at the rear side of the impeller; the shaft (4)
enters the casing via the casing cover. The shaft passage through the bearing bracket
is sealed towards the atmosphere with a shaft seal (9). The shaft runs in a plain
bearing and a rolling element bearing (8 and 10); the bearings are supported by a
bearing bracket (5) linked with the pump casing and/or casing cover.
The pump is sealed by a standardised mechanical seal.
If the pump is fitted with a double-acting mechanical seal, the pump is connected to
a quench pot. The unpressurised quench liquid supply serves to prevent any leakage
of the fluid handled towards the atmosphere. It also prevents any contact between
the fluid and the lubricating grease of the rolling element bearing, especially for
fluids which have a tendency to creep.

✓The 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 use a spirit level to align shaft and
discharge nozzle.
Permissible deviation: 0.2 mm/m
2. If required, use shims (2) to adjust the height.
Always fit shims immediately to the left and right of the foundation bolts (4)
between the baseplate/foundation frame and the foundation itself.
For a bolt-to-bolt clearance > 800 mm, fit additional shims (3) halfway between
the adjoining holes.
All shims must lie perfectly flush.
3. Insert the foundation bolts (4) into the holes provided.
4. Use concrete to set the foundation bolts (4) into the foundation.
5. Wait until the concrete has set firmly, then align the baseplate.
6. Tighten the foundation bolts (4) evenly and firmly.
NOTE
For baseplates more than 400 mm wide it is recommended to grout the baseplate with
low-shrinkage concrete.
NOTE
For baseplates made of grey cast iron it is recommended to grout the baseplate with low-
shrinkage concrete.
NOTE
For low-noise operation contact KSB to check whether the pump set can be installed on
anti-vibration mounts.
