1 IL series Centrifugal marine IN-LINE pumps

2 DESCRIPTION Vertically built centrifugal IN-LINE pumps are made with standardized DIN-22 parts, with in-line suction and discharge flanges. This arrangement requires very limited installation space, making spacesaving a great advantage in the layout design of pumps in the engine room. The flexible coupling design with spacer between pump and motor allows for easy and handy maintenance, since the internal parts of the pump can be reached without the need to remove any pipes or motor parts. IL ILS ILC ILCS In the compact version, with no spacer connection (ILC), dismantling is just as easy, offering the same advantages in terms of access. Service specifications - Maximum flow: m/h - Maximum manometric height: m.c.a. - Maximum turning speed:,00 rpm - Maximum temperature: ºC - Maximum casing pressure: bar CONSTRUCTION - Spiral casing with in-line suction and discharge flanges. - Closed impeller with axial compensation holes. APPLICATIONS The ITUR Pumps IL(S) and ILC(S) series are generally used with clean or slightly laden liquids (fresh water, saltwater, etc) and are very suitable for a wide variety of tasks aboard a vessel: Cooling of main and auxiliary engines Bilge Ballast Fire fighting Cargo tanks cleaning Inert gas seal and cooling Brine circulation Deck washing S.W. fishing park Cooling and air conditioning As there are several possible implementations, these pumps can also be used in land-based industry, water supply and irrigation, particularly in cases where there are space-saving needs in the pumping station. SERIES RANGE The series comprises different sizes of pumps, and can be supplied in four versions of construction: - IL series, with flexible coupling with spacer between pump and motor - ILS series, same as IL series but with automatic priming system - ILC series, compact with rigid connection between pump and motor - ILCS series, same as ILC series but with automatic priming system - Wear rings in pump casing and cover. - DIN-21 PN- flanges, with RF finish, in accordance with DIN- 22 form C; alternatively these can be supplied according to other standards. - Mechanical seal. - Lubricated amply-sized bearings. - I.E.C. in V-1 (vertical) standardized electric motor. These are particularly sturdy pumps. The IL and ILS versions have a two-bearing support, whereas the compact versions (ILC and ILCS) come with an intermediate bearing independent from the actual motor bearings. STANDARDIZED MATERIALS Depending on the type of service and fluids to be pumped, there are different standardized materials: USE Ref.

3 ILS - ILCS SELF-PRIMING SERIES The ILS and ILCS series pumps come with an automatic priming system via an auxiliary liquid ring self-priming pump connected to the main pump. Upon starting up the pump the electrovalve () opens and starts up the auxiliary priming pump (2), which does its job by starting to extract the air in the intake pipes and discharging it through the electrovalve (). The air outlet () should be connected to a suitable drainage area. At the same time, a timer is activated, which after a certain amount of time, gives the start up order to the main pump, with both pumps working jointly. When the water reaches the main pump the pressure is increased; this is detected by the pressure switch (). When it reaches the preset value a second timer is activated, which, after a preset time, disconnects the electrovalve and the auxiliary pump. The timers, as well as the relays and necessary control switchgears, should be integrated in the electric panel. Hence, in the course of a work cycle the auxiliary pump does not run more than strictly necessary in order to properly prime the main pump. It then continues for another few minutes to ensure proper operation, and then shuts off. The priming pump is inactive until it becomes necessary to prime the main pump again. The entire process is fully automatic. INTERCHANGEABILITY OF PARTS In the IL or ILS series the components shown in the top line of the table are standardized and interchangeable among the different models of pumps which have the same letter in the part. Example: the shaft for pump model / is identical and interchangeable with model 1/, since the letter C appears in the shaft column for both. The advantage of this standardization is that with a minimum amount of stock in parts, quick and handy maintenance is ensured for a variety of different pump models.
