better together Why UNIQA? The UNIQA range is designed to meet the real needs of civil and industrial wastewater pumping applications. Its design centres on 3 key concepts, which guided the Zenit engineers in the creation of a genuinely hi-tech product. Innovation Innovating means improving, starting with yourself. We have responded with enthusiasm to a fast-changing market and worked passionately to deliver a high-quality product, the shining gem of today’s Zenit range. UNIQA is innovative in performance and technology. Reliability A product's quality lies first and foremost in its...

better together Tailor-made solutions Every UNIQA model is developed to give the best performance for the duty point, with energy saving assured by efficiency class IE3 motors and high-performance hydraulics. Combining a multinational mentality with flexibility, Zenit guarantees effective solutions and products and systems that are genuinely "made to measure". A modular range The UNIQA series is designed with modularity in mind. This approach gives the customer access to a large number of motor-hydraulics-material combinations, so every model is optimised for its intended use. In practice,...

better together Your guide to UNIQA (WET version) Range with ATEX certification: CABLE GLAND Cable gland system with cable holder. The universal thread ring-nut can be removed to fix a rigid or flexible duct to the cable gland to protect the cable from physical and mechanical stresses. On request a special resin seal is applied to prevent all possibility of water leaking into the motor even if the outer sheath is torn. ELECTRICAL CONNECTIONS The terminal board, which simplifies electrical wiring procedures, is in an airtight compartment which can be fitted with a leakage detection sensor....

better together Exclusive cooling system In DRY version models, the motor is cooled by a water-glycol mix circulating in a special closed circuit. The mix is recycled through the pump by an axial impeller rigidly mounted on the shaft and the specially designed steel double jacket which provides the necessary heat exchange between the motor and the external environment. Thanks to this unique system: - the cooling mix is always separate from the wastewater in which the pump is immersed and cannot be contaminated even if water leaks into the oil chamber due to wear of the first mechanical seal...

better together High efficiency motor The heart of the UNIQA range lies in its high-efficiency electric motors, designed to deliver high performances and withstand continuous duty cycles. • PREMIUM IE3 efficiency • NEMA Class A • Class H insulation for all models in the range. S1 duty mode operation even in water at a temperature of 60°C or above. Clogging-proof hydraulics All hydraulic components are designed using latest-generation software for the highest efficiency and the best performance while still ensuring ample free passages. All models with channel hydraulics feature an axial...

better together Monitoring Every UNIQA model can be fitted with sensors for swift signalling of any anomaly, allowing quick action to protect the pump from potential damage. The monitoring system also acquires data on the operation of the machines installed and helps in the targeted planning of maintenance to avoid sudden system shutdowns. STANDARD • Bimetal thermal sensors (motor) • Single-signal double leakage detector (S) to detect the infiltration into the oil chamber of the mechanical seals and/or into the motor. PTC/PT100 thermistors (motor) Single probes for the detection of water or...

better together Research and development Zenit has a department where innovative solutions are developed by specialist engineers using CAD programs and three-dimensional fluid-dynamic simulation systems. Devices’ hydraulic behaviour can be predicted and their criticalities analysed in the design phase, even before construction of the prototype, cutting costs and shortening times to market. The R&D department also has access to a new testing laboratory, featuring a 9 metre square tank 10 metres deep able to contain 750 m3 of water, enabling technical trials on any product.
