60 Hz PRODUCT RANGEHISTORYZenit was established in the late 1950s. It was founded by Ugo Zeni to build andrepair electric motors and hydraulic pumps.It was based in Modena. It served the Italian market.In 1977 the company reins passed into the hands of the founder's daughter, Adriana,and her husband, Italo Bottan. The range of products Zenit designed and built wasextended: centrifugal, self-priming, volumetric, submerged, submersible and surfaceelectric pumps. The core market continued to be Italy.In 1985 the company took the strategic decision to focus its production efforts onsubmersible pumps for soiled waste water.1990 saw the start of Zenit's expansion on to export markets in Europe, Asia andSouth America. It was also the year when Davide Bottan, the owners' eldest son,joined the firm.From 1990 to 1994 Zenit tripled its turnover and in 1995 it obtained UNI-EN-ISO 9001certification.In 1996 the company moved to the new plant at San Cesario, 10,000 m 2 in area.Lorenzo Bottan, Davide's brother, joined the company.During 1998-2002 the company expanded onto new markets and expanded its rangewith products for wastewater treatment: mixers, aerators and oxygenators.2001 was the year of foundation of APEX, a software firm which became a memberof the Zenit group.Between 2003 and 2004 Zenit was granted UNI-EN-ISO 9001:2000 companycertification and ATEX product certification.In 2006 it opened a new Regional Office in Singapore and in 2007 it inaugurated thenew production and sales location in China, on a site of 16,500 m 2 , with buildingscurrently occupying 8,000 m 2 of this.From 2006 to 2008 Zenit expanded its San Cesario plant to a total of 19,000 m 2 , andstart work on one the construction of one of Europe's most complete test tanks.In 2009 the new EMEA Regional Office (Europe, Middle East and Africa) in Luxembourgstarted operations: buildings of 3,000 m 2 on a site of 6,500.THE ZENIT LOGO1958 1977 2000 20105

lifting systems60 Hz PRODUCT RANGEPrefabricated lifting stations are an effective, economicalsolution for collecting domestic wastewater and transferringit to a sewer at a higher level or where there are barriers togravity run-off, or where the wastewater requires grinding.The BlueBOX series consists of rotary moulded polyethylenetanks of 90, 150, 250 litres, fitted to take one pump or 400litres for two pumps.The special shape is inspired by the Pininfarina design of theBlue Series pumps.Their construction characteristics make BlueBOX systemsextremely versatile and easy to install.Operation and UseThe collection tank receives household wastewater from drains of any kind, and any rainwater or seepage drains.The pump installed inside the tank refluxes the wastewater into the sewer.The cover and pipe joints are fitted with seals to ensure airtight connections.BlueBOX units are designed to allow a large number of intake, outlet and ventilation pipe connection options, allowing effective usewhatever the space available.A grinder pump capable of breaking down any solids in the wastewater, and refluxing it to large distances, can be installed inside the unit.This allows the pumped liquid to be passed through even small-diameter pipelines, with considerable financial savings on the total cost ofthe system.26

60 Hz PRODUCT RANGERemote Control SystemsNowadays, microprocessor remote control systems are an essential tool for the operationof water treatment plants.There are many benefits to be had from the use of remote control systems, due mainly to thecapability for receiving and sending data from and to remote positions in real time.This allows the simultaneous management of several plants, with rapid intervention inresponse to malfunctions only, reducing the costs arising from scheduled services andinspections.What's more, the uniform distribution of the workload across the various machines installedoptimises wear of rotary components, reducing expenditure on parts and labour.The saving of the key data for the pumps installed in a log file allows constant monitoring oftheir operating parameters and scheduling of servicing work to prevent inconvenient plantstoppages.The use of “intelligent” systems also generates an improvementin safety standards. The processing of alarms linked to operatingparameters provides notification and allows immediateintervention in case of malfunctions such as, for example,crossing of level thresholds, dry operation and the accidentalentry of water into the mechanical seal oil sump before theseevents can constitute a threat to normal operation of the plant.There is also a specific input for a tamper alarm, preventingunauthorised modification of the parameters set, ensuringabsolutely safe operation.commander 20-50The COMMANDER is a microprocessor unit for integration in the electricalcontrol panel, capable of managing plant operation.The COMMANDER is available in 2 versions: the COMMANDER 20 for control ofup to 2 pumps and the COMMANDER 50, able to control up to 5 pumps.Use is simplified by a menu which guides the user in the setting and selection ofthe various functions step by step.The user is provided with a liquid crystal display showing plant data and akeypad for setting the operating parameters.35
