STOP must be qualified to carry out the operations described in this manual. Tapflo shall not be held respon- sible for the training level of personnel and for the fact that they are not fully aware of the contents of this manual.
GENERAL Health & safety Electric safety Do not carry out any maintenance operation on the pump while it is running or before it has been dis- connected from the power supply. Avoid any danger caused by electric power (for details see current regulations in force).
INSTALLATION Receiving inspection Although precaution is taken by us when packing and shipping, we urge you to carefully check the ship- ment on receipt. Make sure that all parts and accessories listed on the packing list are accounted for. Immediately report any damage or shortage to the transport company and to us. Storage If the equipment is to be stored prior to installation, place it in a clean location.
INSTALLATION Example of installation Fig. 1 Installation 1) YES: gate valve (may also be near pump in the case of long piping) 2) With positive head: tilt of piping towards pump 3) YES: line strainer if particles are present 4) NO: air pockets: the circuit must be short and straight 5) YES: pipe fixing parts 6) Suction line as short and direct as possible 7) YES: check valve (especially for long vertical or horizontal pipes;...
INSTALLATION Instruments In order to ensure a reasonable control of the performance and the conditions of the pump installed, we recommend using the following instruments: a pressure-vacuum gauge on the suction piping; a pressure gauge on the delivery piping. The pressure intakes must be made on straight pieces of piping at minimum five diameters from the pump inlets.
OPERATION Start-up Check manually that the motor is free to turn, moving the motor cooling fan. Make sure that the piping is not clogged and is free from residues or foreign objects. Make sure that the liquid flows regularly into the pump. The pump and piping connected to it, at least the suction pipe, must be full of liquid.
OPERATION Cleaning and disinfection Cleaning and disinfection of the pump system is of greatest importance when the pump is used in a food STOP process installation. Use of a pump system that is NOT cleaned or disinfected can cause contamination of the product.
MAINTENANCE Maintenance work on electrical installations must be performed by qualified personnel and only when the power supply has been shutoff. Follow the local and national safety regulations. Inspections Periodically check suction and discharge pressures. Inspect the motor according to the instructions from the motor manufacturer. In general, a mechanical seal does not require maintenance, but the pump should never run when empty (dry).
MAINTENANCE Assembly and disassembly The assembly and disassembly should only be performed by qualified personnel. Each operation carried out on the machine must always be carried out once all the electrical contacts have been disconnected. The pump-motor unit must be placed in a position where it cannot be started unintentionally.
MAINTENANCE 3.3.2 Impeller (90) and back casing (12) – disassembly Disassemble the pump casing (13) according to chapter 3.3.1 Remove the impeller mounting screw (191) and the washer (192), use spanner key on the cut in pump shaft (pos. 16) to lock the impeller - Fig 6. Remove the impeller (90).
MAINTENANCE Assembly Before assembly, wet the O-rings on the seal with soapy water. Carefully insert the static part of the seal (15B) in the back casing - Fig 12. Fit the back casing (12) onto the back cover (11) - Fig 13. Check the seal fitting dimensions according to table 3.3.3 to ensure the correct pressure on the seal.
MAINTENANCE 3.3.5 Replacement of motor (1) Follow the instructions for disassembly of the impeller and back casing according to chapter 3.3.2. Remove the deflector (17) from the shaft extension (16) - Fig 18. Remove the back cover screws (121) and washers (122) - Fig 19. Remove the back cover (11).
MAINTENANCE Lubricated seal A great option where there is a potential risk of dry running, or where the product tends to solidify or crystallize. An oil chamber is connected to the mechanical seal chamber. The pump is delivered without lube medium in oil chamber! - Before the first start fill up the oil chamber with proper medium (i.e.
A heating or cooling medium is continuously circulated in the jacket. Back casing heating/cooling system is available in sizes: “C” , “D” and "E" of Tapflo CT pumps. Heating/cooling is operated by a jacket placed in pump back casing (12). The jacket have two G ½”...
