1.0 Introduction 1.1 General This instruction manual contains necessary information on the TopGear pumps and must be read carefully before installation, service and maintenance. The manual must be kept easily accessible to the operator. Important! The pump must not be used for other purposes than recommended and quoted for without consulting your distributor. Liquids not suitable for the pump can cause damages to the pump unit, with a risk of personal injury. 1.2 Reception, handling and sto

1.3 Safety 1.3.1 General Personnel who have a pacemaker should not be allowed to work with the magnetic coupling! The magnetic field is sufficiently strong to affect the operation of a pace- maker. A safe distance is 3 metre! Important! The pump must not be used for other purposes than recommended and quoted for without consult- ing your distributor. A pump must always be installed and used in accordance with existing national and local environ- mental and safety regulations and laws. When ATEX

1.3.2.3 Before commissioning the pump unit Read the pump’s operating and safety manual. Make sure that the installation has been correctly carried out according to the relevant pump’s manual. Check the alignment of the pump and motor shafts. The alignment may have been altered during transport, lifting and mounting of the pump unit. For safe disassembly of the coupling guard see below: Disassembly/assembly of the coupling guard. Warning The pump unit must not be used with other liquids than

2.0 Pump description TopGear MAG pumps are rotary positive displacement pumps with internal gear. They are made of cast iron or stainless steel. TG MAG pumps are assembled from modular elements, which allows a variety of constructions. Different magnet coupling executions, heating/cooling options, several sleeve bearings, gear and shaft materials and mounted safety relief valve. 2.1 Type designation The pump properties are encoded in the following type indication, which is to be found on the

3.2.1 Self-priming operation TopGear pumps are self-priming when sufficient liquid is present in the pump to fill up the clearances and the dead spaces between the teeth. (For self-priming operation see also section 3.18.5.2 Piping). 3.2.2 Safety relief valve – Working principle The positive displacement principle requires the installation of a safety relief valve protecting the pump against overpressure. It can be installed on the pump or in the installation. (See 3.19.4 Checklist – Init

3.7.3 Influences The real sound level of the pump unit can for several reasons deviate from the values listed in the tables above. • Noise production decreases when pumping high viscosity liquids due to better lubricating and damping properties. Moreover the resistance torque of the idler is increasing due to higher liquid friction which results in lower vibration amplitude. • Noise production increases when pumping low viscosity liquids combined with low working pressure because the idle

3.10.2 Maximum temperature of internals For some material combinations the general temperature performances must be limited. The maximum allowable working temperature of internals depends on the combination of materials used and their thermal expansions and the interference fit to hold the bearing bush fixed. • Some bush bearings have an extra loc king screw . In this case the maximum allowable tempera- ture is based on the most probable interference fit. • In case the bearing bush has no
