OPERATING MANUAL - SAXMAG V It is imperative to observe important information/signs directly attached to the machine such as - Sense of rotation arrow - Symbol for liquid connections - Rating plate Make sure they are kept clean and are easily legible. Qualification and training of personnel The personnel entrusted with the operation, maintenance, inspection and installation of the pump must be suitably qualified for the job. -
Page 8: Safety Instructions For Maintenance, Inspection And Installation Work
OPERATING MANUAL - SAXMAG V If hazardous media (e.g. explosive, toxic, hot) leak out, they must be drained off to prevent exposure of people or the environment to any risk. Relevant legal provisions must be observed. Furthermore, the magnetic field might damage data carriers and electronic components. -
Page 9: Filling The Unit
OPERATING MANUAL - SAXMAG V 2.9.1 Filling the unit Normally the system of suction and discharge lines and consequently the pump’s interior that is in contact with the fluid is permanently filled with the pumped medium during pump operation to prevent any potentially explosive atmosphere and the risk of dry running. -

Page 11: Maintenance
OPERATING MANUAL - SAXMAG V Safety information: The relevant admissible operating temperature of the pump is indicated in the data sheet. If the pump is operated at a higher temperature and no data sheet is available or the pump is used as a “pool pump”, contact the manufacturer for the maximum admissible operating temperature of the pump. -
Page 12: Transport, Intermediate Storage
OPERATING MANUAL - SAXMAG V Transport, intermediate storage 3.1 Transport The pump unit must be transported properly by competent personnel. Make sure that the pump or pump unit remains in a horizontal position during transport so that it will not slip out of the transport suspension points. -
Page 13: Intermediate Storage/Preservation
OPERATING MANUAL - SAXMAG V Intermediate storage/preservation As required, pumps should be tested and set using a liquid that also serves to protect the pump’s interior for a period of six months from the time of delivery. This liquid is a mixture of lube oil and passivating neutral detergent. -
Page 14: Description Of The Product And Accessories
OPERATING MANUAL - SAXMAG V Description of the product and accessories General description 4.1.1 General description of the pump V-Series internal gear pumps are volumetric rotary displacement pumps with internal gears designed to deliver fluids of any viscosity. The flow of the fluid to be delivered is produced by two gears: The directly driven rotor designed as a gear and the pinion which, also designed as a gear, engages the rotor in an off-centre configuration. -
Page 15: Operating Principle Of The Gear Pump
OPERATING MANUAL - SAXMAG V 4.1.2 Operating principle Arranged in a pump casing a gear pump has two gears that mesh to provide its pumping action through rotation in opposite senses. The gears are mounted on two shafts which, in turn, are supported in the pump casing and the pump cover. -

Page 17: Bearings
OPERATING MANUAL - SAXMAG V 4.3.1.1 Internal rotor The internal rotor is mounted on the pump drive shaft. The magnets are pasted on the rotor outside and hermetically sealed in to protect them from chemical attack. 4.3.1.2 External rotor The external rotor with the coupling hub is mounted on the motor shaft. The magnets sit on its inside. The magnets actually fitted are provided as a function of the torque to be transmitted by the coupling. -

Page 20: Foundation
OPERATING MANUAL - SAXMAG V Foundation The structure must be prepared such that the dimensions conform to those shown in the dimensional drawing/installation drawing. The concrete foundations shall have a sufficient concrete strength (at least Class X0) to permit safe and functional mounting according to DIN 1045 or an equivalent standard. -
Page 21: Start-Up And Placing Out Of Service
OPERATING MANUAL - SAXMAG V To prevent entry of foreign matter, which may result in destruction of the pump, a suction filter with a filter rating needs to be installed on the inlet side. Given its inner flow resistance, the filter rating must be sufficiently large since it affects the pump's suction capacity. -
