2 Upon request, this coupling can be supplied witha spacer. The use of the semi-flexible coupling with spacer allows easyaccess to the pump interior without the need to remove the pipes or removing the spacer, the assembly made up of the support, coverand impeller is removed, the pump casing and the motor alwaysremaining attached to the bed-plate. The suction and discharge pipesremain this way, maintenance is easier for these pumps that are workingduring industrial NL range of pumps are single-stage horizontal centrifugalpumps, with axial suction and radial discharge, built to StandardISO-2858 (DIN-22858), evolved as a result to applying technologicalinnovation to the design and manufacture of the pumps for pumps are based on the sturdy design of NM series (mediumduty), and they are designed to work in processes with divers types ofliquids and with appropriate materials and mechanical seal.

3 The charac-teristics of the NL series are:- High hydraulic Sturdy design (24/24 hours).-Wide variety of materials available, according to the liquid being Different sealing systems with standardized Different seal cooling Modular pumps (component versatility).- Standardized parts with high degree of Minimal and rapid these pumps are normally driven by electric motor mounted ona bed frame, other power drive sources may be used (diesel engine,steam turbine, hydraulic motor, ..).APPLICATIONSThe NL series of itur Pumps has been specially conceived for thepumping of a wide variety of liquids, generally without, or with slightsuspended matter, such as:- Clean liquids- Corrosive or abrasive liquids- High density liquids- Viscous liquidsThese pumps are designed for pumping systems of industrial proc-esses, where a sturdy larger margin and the reliability of the operatingare necessary.

8 Baseplate number 75-580/2] 120] 160- 3 -- 10 -CONSTRUCTIONPump casingWith volute casing and support feet, it incorporates a wear casing to cover sealing is effected by means of an embed-ded and discharge flangesIntegrally cast with the casing, constructed of GG-25 to DIN-2533, and of steel to DIN-2543, crackle-finished "RF" to DIN-2526 form C. Valid for connecting to commercial flanges DINPN-16. Optionally the casing can be supplied with other types offlanges (ANSI, BS, DIN-2512, etc.).Auxiliary connectionsThe standard version carries vent, drain, seal circulation,pressure and vacuum gauge connections. All of these drilledand closed off with the corresponding coverCasting in one piece, and independent of the seal design, itincorporates several extractors in order to facilitate its ringsAll models incorporate a wear ring in the casing, in order tofacilitate repairs and make them impeller, cast in one piece, hydraulically and dynami-cally balanced, with dorsal fins in order to balance out the axialthrust and to avoid the sedimentation of some suspended matterwhich are carried together with the liquid.

9 It is keyed to the shaftand locked by means of a double shaftWell dimensioned, the shaft is especially resistant to bending. Itis provided with a replaceable shaft sleeve, sealed with theshaft itself by means of a toroidal seal. Thus, changing the shaftcan be avoided, in the case of wear or abrasion in the sealingarea, achieving rapid, cheap maintenance. Included is a deflec-tor next to the support in order to protect the ingress of supportOf modern design, it incorporates two total double seal ballbearings, with grease for its entire lifespan and as such itsmaintenance is not required during normal operation. Thebearing protection against external agents (water, dust, ..) iseffected by means of the lip sealing systemsA wide variety of sealing systems can be incorporated, accordingto the type of liquid to be pumped.

10 The NL series of itur Pumpshas for the standard version, provision for the following possibilities: PackingAsbestos-free, provided with the corresponding Plan API-11. Simple mechanical DIN sealStandardized to DIN-24960, on the long version with lockingpin and choke ring. The material used in the contacting facesdepends upon the liquid to be Plan API-11/61. Simple DIN balanced mechanical sealStandardized to DIN-24960, on the long version with lockingpin and choke ring. Balancing is used when the pressuregenerated in the pump requires it. The material used in thecontacting faces depends upon the liquid to be Plan API-11/61. DIN double mechanical seal ("back to back")Standardized to DIN-24960, on the short version with locking pinonly on the process side, and choke ring.
