Pumps should be grouped together with good maintenance access to the motor, and good personnel access to seals and suction / discharge valves. Maintenance access should allow for removal of the motor either by ‘A' frame, forklift truck or a small crane, motors should point towards the main vehicle access route. Space should be allowed for piston removal on reciprocating pumps. Always check manufacturer's drawings for any special requirements.
Pumps in acid or toxic service should be within a curbed area to contain spillage and a water wash point should be provided near the curbed area. Pumps containing flammable liquids operating above auto ignition temperature present a high fire risk and should not be sited under pipe racks or aerial coolers.
