2.10.1 Marking

The marking on the pump refers to the pump part only. Example of such marking: II 2 G c TX Refer to the Temperature limits table for the temperatures permitted for theindividual pump variants.

An EC manufacturer's declaration is required for the shaft coupling; the shaftcoupling 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 at thesurface 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 thefluid handled. If the pump is heated, the operator of the system is responsible forobserving the specified temperature class and fluid temperature (operatingtemperature). The table below lists the temperature classes and the resulting theoreticaltemperature limits of the fluid handled. (A possible temperature rise in the shaft sealarea has already been taken into account).

The temperature class specifies the maximum permissible temperature at the surfaceof the pump set during operation. For the permissible operating temperature of thepump in question refer to the data sheet.

Table 4: Temperature limits

Temperature class to EN 13463-1 Maximum permissible fluidtemperature

Gland packing

The gland packing consists of braided teflon rings sliding against a bush fitted on therotating shaft. It is used above all for handling sticky fluids or fluids which tend tosolidify, whose lack of lubricating properties would destroy a mechanical seal. Thegland packing can also be fed with a flushing or barrier liquid. This protects thegland packing against overheating and also constitutes a hydraulic barrier betweenthe fluid handled and the atmosphere.

Lip seal

The lip seal consists of a joint ring made of FKM (Viton) or thermoplasticpolyurethane (S1-Ecopur). The lip seal can either be designed to replace a mechanicalseal or to be fitted in the pump from the front end (i.e. rotor end) for greater ease ofmaintenance.

4 Description of the Pump (Set)

18 of 70 Vitalobe

The pump is designed with a radial fluid inlet and outlet in either horizontal orvertical position. The hydraulic system is connected to the motor by a shaft coupling.Normally, frequency inverter controlled geared motors are used. The pump and themotor are mounted on a common baseplate.

The fluid is pumped by two counter-rotating intermeshing rotors (lobes) inside therotor casing (2). Each rotor (3) is mounted on a shaft (6) by means of a screw (4). Theshafts run in bearings located in the bearing bracket (11), and shaft rotation issynchronised via spur gears (10). In the gearbox, the rotation of the driving shaft (9)is transferred to the driven shaft. The rotors (3) inside the casing (2) are synchronisedsuch that they do not contact each other. As the rotor lobes disengage, theincreasing volume between the lobes creates a vacuum on the suction side, drawingthe fluid through the suction nozzle (1) into the rotor casing. The fluid is trapped inthe space between the rotors (between the lobes) and transported through the rotorcasing to the pump's discharge nozzle (14). As the rotors re-engage, the volumebetween them decreases, the pressure at the discharge (14) increases, and the fluid isforced out of the rotor casing. The pump set is bi-rotational, i.e. capable of providingfull pump performance in either direction of rotation. The flow rate is adjusted byincreasing or decreasing the rotational speed of the motor, and thus the rotorrevolutions, as required.

The pump is sealed either by a mechanical seal (5), a shaft seal ring or a glandpacking, depending on the application conditions.

Various seal designs can be used. (⇨ Section 4.1 Page 15)

▷ Always clean the piping and check for contamination before connecting it tothe pump.

NOTEThe piping must be cleaned whenever changes have been made to the system (e.g.after fittings have been installed), without dirt getting into the pump.

5.4.1 Connecting the piping

DANGERExcessive loads acting on the pump nozzlesDanger 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 withouttransmitting any stresses or strains.

▷ Take appropriate measures to compensate thermal expansion of the piping.

CAUTIONIncorrect earthing during welding work at the pipingDestruction 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.

NOTEIt is recommended to install check and shut-off elements in the system, depending on thetype of plant and pump. However, such elements must not obstruct proper drainage orhinder disassembly of the pump.

✓ The suction lift line has been laid with a rising slope, the suction head line with adownward slope towards the pump.

Vitalobe 23 of 70

✓ A flow stabilisation section having a length equivalent to at least twice thediameter of the suction flange has been provided upstream of the suction flange.

CAUTIONDry running of the mechanical seal/pump malfunctionDamage to the pump!

▷ Route the suction line such that air pockets are prevented.

▷ The suction line must not leak.

▷ Avoid sharp bends and valves fitted directly upstream of the pump which wouldaffect the approach flow to the pump and thus the NPSH available.

▷ Install a foot valve for suction lift operation to prevent drainage of the suctionline.

✓ The nominal diameters of the pipelines are at least equal to the nominaldiameters of the pump nozzles.

✓ To prevent excessive pressure losses, adapters to larger diameters have a diffuserangle of approx. 8°.

✓ The pipelines have been anchored in close proximity to the pump and connectedwithout transmitting any stresses or strains.

NOTEIt is recommended to fit gate valves immediately upstream and downstream of the pumpinto the suction and discharge line, respectively. This will prevent the fluid handled fromflowing back when the pump is stopped or removed for servicing/maintenance. Thesegate valves must always be fully open when the pump is running; they must not be usedfor control duties. Operation against a closed gate valve will inevitably result in pump/system damage.

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 suctionand discharge nozzles of the pump.

CAUTIONWelding beads, scale and other impurities in the pipingDamage to the pump!

5.4.3.4 Flushing connection for the mechanical seal

CAUTIONFailure to use or incorrect use of auxiliary connections (flushing liquid)Malfunction of the pump!

▷ Use and install any auxiliary connections in such a way that a proper flow isensured.

CAUTIONIncorrect flushing operationMalfunction of the pump!

▷ The flushing liquid must circulate correctly whenever the pump is running.

▷ The flushing medium used must be compatible with the fluid handled by thepump.Incorrect operation of the flushing system will result in destruction of themechanical seal and contamination of the fluid handled by the flushing medium(and vice versa).

▷ The temperature difference between the flushing liquid and the fluid handledshould not exceed 5° C.

The flushing lines must be connected to the supply and return side of the twomechanical seals, respectively (see Fig.: Mechanical seal flushing system). Flushing isused if the fluid handled tends to crystallise, or solidify when in contact with theatmosphere. The flushing liquid should be supplied at a flow rate of approx. 0.5 to 1l/min and a pressure of 0.5 -1.0 bar (flushing pressure < pump pressure). In the case ofdouble mechanical seals, the flushing pressure can be higher than the pressure insidethe pump, allowing the flushing liquid to be used as a barrier fluid (for hazardousfluids).
