3.18.2 Location
3.18.2.1Short suction line
Locate the pump/pump unit as close as possible to the liquid source and if possible below the liquid supply level. The better the suction conditions, the better the performance of the pump. See also section 3.18.5.2 Piping.
3.18.2.2Accessibility
Sufficient space should be left around the pump/pump unit to allow proper inspection, pump isolation and maintenance.
Sufficient space should be left in front of the pump to enable disassembly of the pump cover, idler and idler pin.
•For loosening pump cover refer to ma
•For disassembling rotating parts (rotor shaft and magnetic coupling) refer to mb
•To adjust pressure of safety relief valve refer to mc
For dimensions of ma, mb, mc see chapter 6.0.

It is imperative that the operating device of pump and/or pump unit is always accessible (also during operation).
3.18.2.3Outdoor installation
The TopGear pump may be installed in the open, the ball bearings are sealed by rubber
3.18.2.4Indoor installation
Locate the pump so that the motor can be vented properly. Prepare the motor for operation according to instructions provided by the motor manufacturer.
When flammable or explosive products are pumped, a proper earthing should be provided. The components of the unit should be connected with earthing bridges to reduce the danger arising from static electricity.
Use explosion free or explosion proof motors according to local regulations. Provide suitable coupling guards and suitable couplings.
Excessive temperatures
Depending on the fluid being pumped, high temperatures may be reached inside and around the pump. From 60°C onwards the safety representative must provide the necessary protective means and place “Hot surfaces” notices.
When insulating the pump unit, ensure that adequate cooling is allowed for the bearing housing. This is required for cooling of the bearings and grease of the bearing bracket.
(see 3.18.7.7 Guarding of moving parts).
Protect the user against leakages and possible liquid streams.
