Manual No/Rev W12-005E / 3 1. Operators Instructions for Horizontal Extended Thrustream Centrifugal Pumps General Information and Safety Instructions The products supplied by SPP Pumps Ltd. have been designed with safety in mind. Where hazards cannot be eliminated, the risk has been minimised by the use of guards and other design features. Some hazards cannot be guarded against and the instructions below MUST BE COMPLIED WITH for safe operation.
Operators Instructions for Horizontal Extended Thrustream Centrifugal Pumps The use of suitable forklift truck and four-chain crane sling equipment is recommended but locally approved equipment of suitable rating maybe used. Manual No/Rev W12-005E / 3 When pumps are not in use, the pump shaft should be rotated several turns, every six weeks. 2.3.2 Long Term Storage Pumps are usually supplied on pallets for handling by forklift truck, to lift from the pallet the pump should be slung as shown.
Manual No/Rev W12-005E / 3 Operators Instructions for Horizontal Extended Thrustream Centrifugal Pumps The standard pump is soft packed but the option to fit internal component mechanical seals or selected external cartridge mechanical seals is provided to suit customer’s requirements. These pumps are normally supplied with a cast iron casing and impeller but bronze may be supplied where required. Other parts may be supplied in a variety of materials to suit the pump application.
Operators Instructions for Horizontal Extended Thrustream Centrifugal Pumps Remove packaging but leave the flange covers in place, check that impeller rotates freely by hand by turning the shaft. into the pump. A screen or basket strainer may also be required to hold back larger items. These should be sized to maintain the flow through them to below 0.6 m/s. If the pump has been in storage, remove any protective coatings.
Manual No/Rev W12-005E / 3 4.9 Operators Instructions for Horizontal Extended Thrustream Centrifugal Pumps faces. These should be checked for cleanliness before assembly and before resorting to using shims under the motor feet. Coupling Alignment To minimise the bearing loading and to achieve full coupling and bearing life, it is recommended that the shafts are aligned as accurately as possible i.e. well below the allowable misalignment of the coupling.
Operators Instructions for Horizontal Extended Thrustream Centrifugal Pumps Disconnect the pump drive by removal of the spacer from the coupling. Connect the electrical supply to the pump unit. Momentarily switch on motor and check direction of rotation. This should match the direction of rotation of the pump. For three phase electric motors, if the direction of rotation is incorrect, disconnect the supply and change over two of the three supply phases. Replace the coupling spacer. 5.2 5.
Manual No/Rev W12-005E / 3 Operators Instructions for Horizontal Extended Thrustream Centrifugal Pumps c) Suction Gauge Reading: If this is lower than normal, investigate and check that valves in the suction pipework are fully open or that the suction lift may have increased. d) Discharge Gauge Reading: If this is lower than normal, check for a leak in the associated pipework or that a valve in the delivery line has been opened when normally it is partially closed. 5.
Operators Instructions for Horizontal Extended Thrustream Centrifugal Pumps 6.1 46 Preparation for Maintenance Manual No/Rev W12-005E / 3 51 Electric Shock & Accidental Starting Hazard ISOLATE the equipment before any maintenance work is done. Switch off the mains supply, remove fuses, apply lock-outs where applicable and affix suitable isolation warning signs to prevent inadvertent re-connection. During maintenance personnel should be aware of the risks of inhaling dangerous fumes or vapours.
Manual No/Rev W12-005E / 3 Operators Instructions for Horizontal Extended Thrustream Centrifugal Pumps 45 by cutting off lubrication to the packing, and the packing will burn and damage the sleeve. o 6.3 9 Generally no maintenance is required on mechanical seals. They should be replaced if leakage occurs but if maintenance is required, the manufacturer's information is given in Appendix IIl. Cut each ring from the spiral at an angle of 45° diagonally across the guidelines.
Operators Instructions for Horizontal Extended Thrustream Centrifugal Pumps bearing can cause severe damage. The work area and all tools used for bearing replacement must be clean and free of dust and grit to prevent contamination of a clean bearing and new grease. Ball bearings should not be dismantled.
