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. If staff do not have the relevant knowledge, they should be provided with suitable instruction. The operating safety of the pumps or units (i.e.
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 and in the Confirmation of Order. This applies particularly for the endurance of the materials and smooth running of the pump and shaft sealing. If one or more aspects of the actual operating conditions are different, we should be asked to confirm in writing that the pump is suitable. 1.
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. If abnormal operation or any damage are observed, the pump must cease operation immediately.
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 do not exceed the limit values given. In addition, the pump must be protected against pressure surges such as can be caused by switching off the plant quickly (e.g. by non-return valve on the pressure side, flywheel, air vessel).

Operating instructions 2.2 Permissible Temperatures The values stated in the Confirmation of Order always apply. It is not permitted to exceed or go below these values. If no temperature is given in the Confirmation of Order the maximum permissible pumping medium temperature is 95° C. 2.3 Bearings and Lubrication The roller bearing situated above the shaft takes up the axial forces and radial forces which occur near the coupling. It is filled with grease for its life cycle and thus requires no maintenance.
Operating instructions Automatic Control • Automatic Operations can be attained by fitting a mercury level switch (e.g. Type NGE) or an electrode switch. • The switching device needed to turn the motor on and off (circuit breaker ,Y-∆-automatic circuit breaker) must be suitable for momentary contact control. • An alarm switch functioning independently of the mains can be fitted if desired. 3. Transport, Handling, Storage 3.
Operating instructions 3.2 Storage Pumps or pump units that are stored for a long time before use must be protected against moisture, vibrations and dirt (e.g. by wrapping in oil paper or plastic sheeting). Pumps must basically be stored in a place where they are protected from the weather, e.g. under cover. During this time, all suction and discharge branches and all other intakes and outlets must be closed with dummy flanges or plugs. 4. Assembly, Operation 4.
Operating instructions a screw locking liquid or a centre punch mark. Afterwards when the pipe support clamp has been removed, the pump can be lowered to plate 380 and after inserting the O-ring supplied (to seal against smell) screwed to the foundation frame. To seal against smell place the sealing discs supplied underneath the plate screw fitting (screw head or hexagon nut). 4.3 Connecting the Pipes to the Pump • When laying the pipes make sure that the pump is accessible for maintenance and assembly.
Operating instructions Setting the Level Switch Guide the cables of any level switches through the cable stuffing box of the switch cover 382/S and and clamp according to the desired switching levels. Initial Operations Remember that when starting against closed pressure line valves the power consumed by the pump is converted to heat and and discharged to the pumping medium.
Operating instructions Please note Regular monitoring and maintenance will extend the life of your pump or pump system. • You must observe the area of application given in the Confirmation of Order. • Do not exceed the output given on the motor rating plate. • Running dry, running against a closed pressure side valve or operating in the steam phase of the pumping medium are to be avoided at all costs. • Avoid sudden changes in temperature (temperature shocks).
Operating instructions 5. Maintenance, Servicing Work should only be carried out on the pump or pump unit when it is not in operation. You must observe Point 1.4 „Safety instructions“. Please note Maintenance and servicing work must only be carried out by trained, experienced staff who are familiar with the contents of these Operating Instructions, or by the Manufacturer's own service staff. The work carried out must be duly entered in the „Log Book“ (see Point 11) and confirmed by being signed.
Operating instructions should be particularly taken into account. If necessary, the written agreement of the manufacturer must be obtained. Faults Discharge too low Discharge stops after a time Head too low Head too high Drive mechanism overloaded Pump not running quietly Temperature in the pump too high Temperature at the bearing too high Code no.
Operating instructions 9. Air pocket in pipeline • vent • improve course of pipe 10. NPSH of system too small increase liquid level 11. Air being sucked in • increase liquid level 12. Direction of rotation is wrong • swap over two phases of power supply (to be done by a specialist electrician) 13. Inner components suffering from wear • replace worn parts 14. Density and/or viscosity of liquid handled is too high • seek assistance 15.
Operating instructions 22. Discharge too high • reduce amount carried (throttle slide valve) 23. System-related vibrations (resonance) • seek assistance 24. Manometer indicator wrong • check manometer • get rid of blockages • put manometer in suitable place (no flow distortion or burbling) 8. Repairs Repairs to the pump or pump system may only be carried out by authorised skilled personnel or by the manufacturer's specialist staff. We would be pleased to send you detailed repair instructions on request.
Operating instructions Please note To ensure optimum availability, we recommend that suitable quantities of spare parts are held in stock, especially if these are made from special materials and in the case of mechanical seals, because of the longer delivery times. Ordering Spare Parts When ordering spare parts, please supply the following information: • Type: ________________________ Order no.
