Safety

2 Safety

The manufacturer does not accept any liability for damageresulting from disregard of the entire documentation.

2.1 Intended use• Only use the pump to pump the agreed pumped liquids

(→ additional instructions - pump data sheet).

• Adhere to the operating limits (→ pump data sheet).

• Avoid running dry for prolonged periods:

– The pump can be run dry for brief periods (dependingon the pumped liquid, application process and type ofseal). Consult the manufacturer if necessary.

– Make sure the pump is only operated with, and neverwithout, pumped liquid.

• Avoid cavitation:– Fully open the suction-side valve and do not use it to

adjust the flow rate.– Open the pressure-side valve completely.

• Take system-side measures (e. g. safety valve) whichprotect the pump from impermissible overpressure.

• Consult the manufacturer about any other use of the pump.

Prevention of obvious misuse (examples)• Observe the operating limits of the pump with regard to

the temperature, pressure, viscosity, flow rate and speed(→ pump data sheet).

• When pumping liquids containing solids, adhere to thelimits for the proportion of solids and the grain size(→ pump data sheet).

• Do not operate the pump while the suction-side orpressure-side valves are closed.

2.2 General safety instructionsTake note of the following regulations before carrying outany work.

2.2.1 Product safetyThe pump has been constructed according to thelatest technology and recognized technical safety rules.Nevertheless, operation of the pump can still put the life andhealth of the user or third parties at risk or damage the pumpor other property.

• Only operate the pump if it is in perfect technical conditionand only use it as intended, staying aware of safety andrisks, and in adherence to the instructions in this manual.

• Keep this manual and all other applicable documentscomplete, legible and accessible to personnel at all times.

• Keep the information on the machine in a complete andlegible condition.

• Refrain from any procedures and actions that would posea risk to personnel or third parties.

• In the event of any safety-relevant malfunctions, shut downthe pump immediately and have the malfunction correctedby appropriate personnel.

• In addition to the entire documentation for the product,comply with statutory or other safety and accident-prevention regulations and the applicable standards andguidelines in the country where the pump is operated.


Safety

2.2.2 Obligations of the operating company

Safety-conscious operation• Only operate the pump if it is in perfect technical condition

and only use it as intended, staying aware of safety andrisks, and in adherence to the instructions in this manual.

• Ensure that the following safety aspects are observed andmonitored:– Adherence to intended use– Statutory or other safety and accident-prevention

regulations– Safety regulations governing the handling of

hazardous substances– Applicable standards and guidelines in the country

where the pump is operated

• Make protective equipment available.

Qualified personnel

• Make sure all personnel tasked with work on the pumphave read and understood this manual and all otherapplicable documents, especially the safety, maintenanceand repair information, before they start any work.

• Organize responsibilities, areas of competence and thesupervision of personnel.

• Have all work carried out by specialist technicians only:– Installation, initial start-up, repairs, maintenance– Work on the electrical and electronic equipment

• Make sure trainee personnel only work on the pump undersupervision of specialist technicians.

Safety equipment

• Provide the following safety equipment and verify itsfunctionality:– For hot, cold and moving parts: safety guarding

provided by the customer for the pump– For potential build up of electrostatic charge: ensure

appropriate grounding.– provide an appropriate safety valve on the pressure

side between the pump and the first shut-off device

Warranty

• Obtain the manufacturer's approval prior to carrying outanymodifications, repairs or alterations during the warrantyperiod.

• Only use genuine parts or parts that have been approvedby the manufacturer.

2.2.3 Obligations of personnel

• All directions given on the pumpmust be followed (and keptlegible), e.g. the arrow indicating the sense of rotation andthe markings for fluid connections.

• Do not remove the safety guarding for hot, cold or movingparts during operation.

• Use protective equipment whenever necessary.

• Only carry out work on the pump while it is not running.

• Isolate the motor from its supply voltage and secure itagainst being switched back on again when carrying outany fitting or maintenance work.

• Reinstall the safety equipment on the pump as required byregulations after any work on the pump.

2.3 Specific hazards

2.3.1 Explosion-hazard area

• (→ ATEX additional instructions).

2.3.2 Hazardous pumped liquids

• Follow the safety regulations for handling hazardoussubstances when handling hazardous (e.g. hot,flammable, poisonous or potentially harmful) pumpedliquids.

• Use protective equipment when carrying out any work onthe pump.

Do not touch the running pump.Do not carry out any work on the running pump.Isolate the motor from its supply voltage and secure itagainst being switched back on again prior to any fitting ormaintenance work.



WARNINGCleaning agents present a risk of poisoning in thefoodstuffs industry!

Only use cleaning agents which are compatible with thepumped liquid.Use the cleaning agent specified by the manufacturer.Observe company-internal cleaning guidelines.

CAUTIONMaterial damage due to water in the area around thebearings!

Seal the bleed hole in the oil filler plug.

1. Disconnect the suction and pressure lines from the pumpcasing.

2. For pumps with axial supports, remove the pipe adapter.3. Unscrew the fastening screws.4. Carefully remove the pump casing.5. Remove seal ring on the intermediate flange.6. Clean/sterilize the pump casing and internal pump

components with a suitable cleaning agent.7. Insert a new seal ring (SL series only) in the intermediate

flange and use a blunt object to press it down into thegroove.

8. Carefully slide the pump casing over the spindles whileobserving the installation position of the suction pipeand outlet flange (→ additional instructions - dimensionaldrawing).

9. Screw in and tighten the fastening screws.10. Remove the seal from the bleed hole in the oil filler plug.

✔ Stand-by pump filled and bledOperate the pump and stand-by pump alternately.


Maintenance

7 Maintenance


Trained service technicians are available for fitting andrepair work. When requesting service, present a pumpedmedium certificate – DIN safety data sheet or document ofcompliance (→ 9.7 Document of compliance, Page 41).


7.1 InspectionsThe inspection intervals depend on the operational strainon the pump.


Do not touch the running pump.Do not carry out any work on the running pump.



1. Check at appropriate intervals:– Temperature of antifriction bearings with metal cage

(alarm at 100 °C, shutdown ≤ 120 °C)– Normal operating conditions unchanged– Coupling alignment and condition of elastic parts– If present, make sure the safety valve is functioning

properly (→ manufacturer's specifications)– Blocking pressure system, condition of the blocking

medium2. For trouble-free operation, always ensure the following:

– No dry running for prolonged periods– No leaks– No cavitation– Suction-side gate valves open– Pressure-side gate valve open– Unclogged and clean filters– No unusual running noises or vibrations– No excessive leakage at the shaft seal– Function of the auxiliary operating systems

7.2 MaintenanceMechanical seals have functional leaks (→ manufacturer'sspecifications).Mechanical seals are subject to natural wear, which islargely dependent on the respective operating conditions(e.g. pumped liquid, continuous or intermittent operation,etc.). Therefore, general statements regarding theirservice life cannot be made.

Intermittent operation, high temperatures, low viscositiesand aggressive ambient and processing conditions reducethe service life of the bearings.

7.2.1 Maintenance table


Have all electrical work carried out by qualified electriciansonly.




Make sure the coupling guard is fitted after working on thepump.

WARNINGRisk of injury and poisoning due to hazardous or hotpumped liquids!

Use protective equipment when carrying out any work onthe pump.If possible: allow the pump to cool down beforecommencing work.Make sure the pump is switched off and depressurized.Empty the pump, safely collect the pumped liquid anddispose of it in accordance with environmental rules andrequirements.

Perform the maintenance work as specified in the followingtable unless required otherwise by the operating mode.
