Page 5: General
Operating instructions 1. General 1.1 Foreword This product complies with the safety requirements of EC Machinery Directive 2006/42/EC. The staff employed on installation, operation, inspection and maintenance must be able to prove that they know about the relevant accident prevention regulations and that they are suitably qualified for this work. -
Page 6: Safety Regulations
Operating instructions In order for the guarantee to apply, it is essential that the pump or pump unit is used in accordance with the operating conditions given on the type plate, confirmation of order and in the Data Sheet. This applies particularly for the endurance of the materials and smooth running of the pump and shaft sealing. -
Page 7: Safety Instructions For The Operator
Operating instructions Safety instructions for the operator • Depending on the operating conditions, wear and tear, corrosion or age will limit the working life of the pump/pump unit, and its specified characteristics. The operator must ensure that regular inspection and maintenance are carried out so that all parts are replaced in good time which would otherwise endanger the safe operation of the system. -
Page 8: Speed, Pressure, Temperature
Operating instructions Speed, Pressure, Temperature Suitable safety measures must be taken at the plant to ensure that the speed, pressure and temperature of the pump and the shaft sealing do not exceed the limit values given in the Data Sheet. The given admission pressures (system pressures) must also be sufficiently high. In addition, the pump must be protected against pressure surges such as can be caused by switching off the plant quickly (e.g. -
Page 9: Back Flow
Operating instructions Back flow In systems where pumps are operating in closed circuits under pressure (gas cushions, steam pressure), the pressure of the gas cushion must not be reduced via the pump, since the back flow speed may be much higher than the operating speed, which would destroy the unit. 2. -

Operating instructions Please note Please Sling ropes must not be fixed to ends of shafts or the ring loops of the motor. note Do not stand underneath suspended loads; take note of the general regulations on prevention of accidents. The pump/pump unit must be secured against tipping over and slipping until it has been fixed in its final location. -
Page 12: Installation And Alignment Of Coupling
Operating instructions To prevent vibrations being transmitted to adjoining components, the foundation should be laid on a suitable insulating base (panels providing insulation against structure-borne sound or vibration panels). Please The size of these insulating panels will vary, depending on circumstances, and note should therefore be determined by an experienced specialist.. -

Operating instructions Adjustment using dial gauge: Adjustment using precision ruler: Normal coupling Expansion coupling • Check/measure the alignment at several points using a precision ruler and sensor. If a dial gauge is used, one coupling side is to be turned. •... -
Page 14: Connecting The Pipes To The Pump
Operating instructions Design NAN.. and NHN.. • Align the coupling again after pump has reached normal operating temperature and system pressure (if applicable), check once again and if necessary adjust. Read Point 4.5 „Starting up“ first. • It must be possible to turn the unit by hand smoothly and easily. •... -
Page 15: Auxiliary Pipes
Operating instructions • Before connecting up to pump: remove protective coverings from suction and discharge branches. • To protect the shaft sealing (especially mechanical seals) against foreign bodies, it is recommended that a sieve, 800 micron, is installed in the suction/intake pipe when the motor is being started up. -
Page 16: Starting Up
Operating instructions 4.5 Starting up The plant may only be started up by people who are familiar with the local safety regulations and with these Operating Instructions (especially with the safety regulations and safety instructions given here). In order to be able to observe and monitor the shaft sealing, no protective covering is provided in this area. -
Page 17: Operation And Monitoring
Operating instructions 4.6 Operation and Monitoring Be particularly careful not to touch hot machine parts and when working in the unprotected shaft seal area. Remember that automatically controlled systems may switch themselves on suddenly at any time. Suitable warning signs should be affixed. Please Regular monitoring and maintenance will extend the life of your pump or pump note... -
