2.8 Unauthorised modes of operation

Never operate the pump (set) outside the limits stated in the data sheet and in this manual.

The warranty relating to the operating reliability and safety of the supplied pump (set) is only valid if the equipment is used in accordance with its intended use. (ðSection2.2,Page8)

2.9 Explosion protection

Always observe the information on explosion protection given in this section when operating the product in potentially explosive atmospheres.

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 EU Directive 2014/34/EU (ATEX). Especially adhere to the sections in this manual marked with the symbol opposite and the following sections, (ðSection2.9.1,Page10) to (ðSection2.9.4,Page11) 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.

2.9.1 Marking

Pump The marking on the pump refers to the pump part only.

Example of such marking: II 2 G c TX (EN 13463-1) or II 2G Ex h IIC T5-T1 Gb (ISO 80079-36)

Refer to the individual Temperature Limits table for the temperatures permitted for the individual pump variants.

The pump complies with the requirements of type of protection constructional safety "c" to ISO80079-37.

Shaft coupling An EC manufacturer's declaration is required for the shaft coupling; the shaft

coupling must be marked accordingly.

Motor The motor must be considered separately.

2.9.2 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 in addition, the operator of the system is responsible for observing the specified temperature class 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.

T1 Temperature limit of the pump T2 Temperature limit of the pump T3 130 °C T4 60 °C

If the pump is to be operated at a higher temperature, if there is no data sheet or if the pump is part of a pool of pumps, contact KSB for the maximum permissible operating temperature.

If a pump is supplied without motor (as part of a pool of pumps), the motor specified in the pump data sheet must meet the following conditions:

▪ The permissible temperature limits at the motor flange and motor shaft must be

higher than the temperatures generated by the pump.

▪ Contact the manufacturer for the actual pump temperatures.

2.9.3 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 about monitoring equipment.

Maximum permissible

fluid temperature

2.9.4 Operating limits

The minimum flows indicated in (ðSection6.2.5.1,Page42) refer to water and water-like fluids handled. Longer operating periods with these fluids and at the flow rates indicated will not cause an additional increase in the temperatures at the pump surface. However, if the physical properties of the fluids handled are different from water, it is essential to check whether an additional heat build-up may occur and if the minimum flow rate must therefore be increased. The calculation formula in (ðSection6.2.5.1,Page42) can be used to check whether additional heat build-up may lead to a dangerous temperature increase at the pump surface.

1 Volute channel 2 Discharge nozzle 3 Clamping piece 4 Pump shaft 5 Rolling element bearing for pump

shaft 7 Suction nozzle 8 Impeller 9 Casing cover 10 Shaft seal 11 Bearing assembly 12 Drive

Design The pump is designed with an axial fluid inlet and a radial outlet. The hydraulic

system is rigidly connected to the motor via a stub shaft.

Function The fluid enters the pump via the suction nozzle (7) and is accelerated outward in a

radial flow by the rotating impeller (8). In the flow passage of the pump casing (1) the kinetic energy is converted into pressure energy. The fluid is pumped to the discharge nozzle (2), where it leaves the pump. At the rear side of the impeller, the shaft (4) enters the hydraulic system via the casing cover (9). The shaft passage through the cover is sealed to atmosphere with a dynamic shaft seal (10). The pump shaft runs in a rolling element bearing (5), which is supported by a bearing assembly (11). The motor shaft is inserted into the pump shaft (stub shaft). The drive (12) is connected to the pump via the drive lantern (6).

Sealing The pump is sealed by a mechanical seal.

CAUTION

Risk of freezing during prolonged pump shutdown periods

Damage to the pump!

▷ Drain the pump and the cooling/heating chambers (if any) or otherwise protect

them against freezing.

6.1.7 Seal supply system

6.1.7.1 Application

In order to function properly, the mechanical seals require a flushing liquid. The flushing liquid completely fills the space between the inboard and the outboard mechanical seal.

6.1.7.2 Requirements to be met by the seal supply system

When routing pipework and flexible tubing, prevent any high points or ensure that high points can be vented separately to prevent dry running of the mechanical seal. The connecting pipes between the main pipe and the pump must be routed with a continuously rising slope to assure self-venting of the pipe and the mechanical seal, respectively.

6.1.7.3 Types of seal supply systems

Which of the two types of seal supply systems is used depends on the mechanical seal:

6.1.7.3.1 Quench liquid

6.1.7.3.1.1 Applications

A quench liquid is used in the following cases:

▪ Where a single mechanical seal without supportive measures would not work at

all or unsatisfactorily.

▪ Where a double mechanical seal design with pressurised barrier fluid is not

required.

6.1.7.3.1.2 Quench liquid requirements

The quench liquid should preferably form a solution with the fluid handled and be environmentally compatible.

Typical quench liquids ▪ Water with a conductivity of 100 - 800 µS/cm

▪ Water/glycol mixture

▪ Glycerine

The quench liquid should be supplied to the mechanical seals unpressurised (at atmospheric pressure), if possible. Positive pressures of up to 0.5 bar are acceptable.

The one-way quench supply should be adjusted to a constant flow ≥0.4l/min. Periodically check the quench liquid for contamination (replace quench liquid and

clean quench system if necessary).

6.1.7.3.1.3 Applications

6.1.7.3.2 Barrier fluid system

6.1.7.3.2.1 Applications

Barrier fluid systems serve to:

▪ Dissipate friction heat ▪ Prevent the fluid handled from entering the sealing gap

6.1.7.3.2.2 Barrier fluid requirements

The barrier fluid should preferably form a solution with the fluid handled and be environmentally compatible. The barrier fluid should be monitored: Any ingress of the fluid handled can be identified at an early stage by the barrier fluid becoming turbid.

The temperature differences between the barrier fluid and the fluid handled must not exceed 5°C. A general minimum temperature of 0°C applies to the barrier fluid.

The barrier fluid system must be set to a pressure which exceeds the pressure inside the pump by approximately 0.5 to 1bar.

General rule: The maximum permissible pressure inside the barrier fluid system equals 10bar. Actual maximum permissible pressure depending on the material combination and shaft diameter:
