The firm Ercone Marelli pumps led to the last edition of the international water exhibition, Smagua, held at the fair of Zaragoza from 11 to 14 March, its new range of centrifugal pumps CF/FQX, among other options.

The company was present with a booth in the tenth eighth edition of the international water exhibition in Zaragoza with a wide range of their latest products. Thus, the company presented its new range of centrifugal pumps which are designed for applications of greater responsibility and for the most demanding specifications made according to the needs of the client. Ercone Marelli pumps used the occasion of the event to present to customers and visitors new bombs CF and FQX, vertical double suction machines.

Marelli has developed a complete range of pumps used in desalination systems. Since the sea water or brackish water with large flow rates and low pressures and stockings, to high pressure in plant bombs, the signature offers a wide range of action comprising flows of 20,000 m3/h up to 1,080 metres of water column pressure.

From the type of bombs with which they work include the horizontal split camera monoetapa (PDH), horizontal radial seal (TKI/TKO) multistage, horizontal camera multistage (DVMX), vertical double suction (CF), semiaxiales vertiacles monoetapa and multistage (FG) and standardized DIN 24256 (ND).

The important part of the development is geared to ensure the continuous operation of the plant with high yields. The selection and use of materials such as the duplex and super duplex ensure high levels of reliability and performance.

Supply, sanitation and water treatment

The technology of water treatment and the provision for the use of more developed societies has allowed to increase the levels required on all computers. So Marelli pumps, faithful to the criteria of this type of very specialized client, has created a range of centrifugal pumps with ad hoc criteria. For this market, the company designs and manufactures pumps up 42,000 m3/h and pressures of up to 500 meters column of water. In this regard, the signing gives rise to horizontal pumps party House monoetapa (PDH), horizontal split camera of double stage (PDHH), horizontal multistage radial seal (TKN/TKI), vertical double suction (CF), vertical double suction semiaxiales stages (FQX)vertical, semiaxiales, monoetapa and multistage (FG), standardized 24256 DIN (ND) and standard DIN 24255 (NEI).

Improvements in the designs of these families of pumps are aimed at increasing the cycle of life, defining mechanical double seam applications loaded waters, and packings in those cases which require more maintenance. The materials for these applications are based on cast iron GG25, being the analysis of pumped water who marks the use of one or other material to Aisi 604 L, with most required uses.

For irrigation and transport, Marelli develops technical solutions for easy installation and low maintenance, to ensure lower costs (LCC) pumps life cycle. This design allows the end customer programmes of preventive maintenance with low investment and high screening in the permanence of the station without failures. The company provides the solution PDHV (game camera in vertical pumps), which allow having a lower cost of the civil works, to be a compact mechanical solution, and create a more reliable team by not having to use the engine coupling. With design capacity of up to 15,000 m3/h and pressures of up to 400 meters column of water, Marelli cover design solutions consistent with the applications in this market.

In that regard, the company offers vertical pumps starting camera monoetapa (PDHV), horizontal camera item monoetapa (PDH), horizontal split House of double stage (PDHH), horizontal multistage radial seal (TKN), vertical double suction (CF), vertical double suction semiaxiales stages (FQX)vertical, semiaxiales, monoetapa and multistage (FG/FV), standardized 24256 DIN (ND) and standard DIN 24255 (NEI).

Pumps working in discontinuous regime with a high-maintenance, being simple machines service and low maintenance costs are valued in irrigation and transport. The pumps are designed with criteria of robustness and simplicity mechanical, installing in the majority of cases packing before mechanical closures, to increase the MTBF (mean time between failures).
