Manual No/Rev W21-002E / 10 1.7 1.8 1.9 Operators Instructions for Unistream Centrifugal Pumps Note any limits to the pump application specified in the contract documentation. Operation of the equipment outside these limits will increase the risk from hazards noted below and may lead to premature and hazardous pump failure. Pumps supplied on pallets may be lifted by forklift truck, to lift from the pallet the pump should be slung as shown. Clear and easy access to all controls, gauges and dials etc.
Operators Instructions for Unistream Centrifugal Pumps parts for storage with the pump. The pump shaft should be rotated by hand at least five turns every six weeks. For special protection of the coupling and electric motor, where applicable, refer to the manufacturers' instructions in the relevant appendix. 2.3.3 Exposed or Extreme Conditions Storage For exposed storage or extreme atmospheric or environmental please refer to SPP Pumps Ltd. storage instructions to suit the applicable.
Manual No/Rev W21-002E / 10 Operators Instructions for Unistream Centrifugal Pumps 4.3 Pump Preparation Abrasion and Entrapment Hazard Do NOT touch any moving or rotating parts. Guards are provided to prevent access to these parts, where they have been removed for maintenance they MUST be replaced before operating the equipment. Remove packaging but leave the flange covers in place, check that impeller rotates freely by hand by turning the shaft. 4.

Manual No/Rev W21-002E / 10 Operators Instructions for Unistream Centrifugal Pumps If the stuffing box is supplied with cooling water or the mechanical seal is supplied with clean water flush, check that the water supply is turned on. Failure to supply the stuffing box or mechanical seal with cooling or flush water may result in damage and premature failure of the pump. ATTENTION Check that the rotating assembly is free to rotate by hand before connecting the power supply.
Operators Instructions for Unistream Centrifugal Pumps signal can still be heard with ear defenders worn. Hazardous Gases, Mists, Sprays and Leaks Be aware of the hazards relating to the pumped fluid, especially the danger from inhalation of noxious and toxic gases, skin and eye contact or penetration. Obtain and understand the hazardous substance (COSHH) data sheets relating to the pumped fluid and note the recommended emergency and first aid procedures.
Manual No/Rev W21-002E / 10 Operators Instructions for Unistream Centrifugal Pumps drained down. Hazardous Materials Wear a suitable mask or respirator when working with Packing and Gasket components that contain fibrous material, as these can be hazardous when the fibrous dust is inhaled. Be cautious, if other supplier's components have been substituted for genuine SPP Pumps Ltd parts, these may then contain hazardous materials.
Operators Instructions for Unistream Centrifugal Pumps and without Lantern Ring 6 6 6 If the packing rings are to be cut from a coil, or length of packing, the size, number of rings and length are shown in the tables. Wrap the packing strip around a dummy shaft of the required diameter, overlapping the coils as shown. Cut diagonally at 45° to produce rings with an overlapped split joint. Note that if packing is cut from flat material or with square joint lines, a good seal will not be achieved.
Manual No/Rev W21-002E / 10 Operators Instructions for Unistream Centrifugal Pumps mechanical seal (43.3), from the bearing housing (33.0). Care must be taken to ensure that the stationery element of the seal and the shaft are not damaged when extracting the shaft. Undo the impeller nut (92.2) in a counter clockwise direction and withdraw the impeller (23.0) from the shaft (21.1).
