With our extensive product line, we support our customers worldwide in successfully mastering demanding pumping tasks in the fields of water supply, mining, industry and sewage.For planners and users.The RITZ product range.This brochure will give you an overview of our product rangeand will help you to quickly find the right RITZ product for yourspecifi c applications.We have prepared detailed technical information on the indi-vidual product groups, and would be happy to provide them toyou on request.For water supply.More water – less costs.In all sectors of water management, RITZ pumps play a majorrole in the abstraction and distribution of this valuable resource.What is more, the high effi ciency of our products makes itpossible to reduce operating costs. This means that investmentin a RITZ pump amounts to less than 1 % of the energy costsover ten years.For mining.Highest reliability under severestconditions.One of the most important requirements for trouble-free extrac-tion operations is pumping the accumulated mine water outof the working area. Mine operators all over the world rely onsingle-suction and double-suction submersible motor pumpsand high-pressure pumps from RITZ to carry out this import-ant task.For industry.Flexibility and highest econo o mics.RITZ industrial pumps can be used in almost any ap p plication in-volving the pumping of coolants, auxiliary substance e s or operat-ing media in secondary circuits, or where demand ndary circuits, or where demanding washing and cleaning proces s ses are necessary in raw materials handling. RITZ pumps can o o perate in extreme temperatures and under high pressure, in a ggressive and corrosive media and media containing solids, transporting coolants, lubricants, a ransporting coolants, lubricants, acids, bases and oils.For sewage.– maxim m um Long service life – economics.Almost anywhere that sewage has to be moved, wherever relia-Almost anywhere that sewage has to b bility and cost-effectiveness are the main crite e ria in intelligent bility and cost-effectiveness are the m decisions, solutions from RITZ are the right choice.decisions, solutions from RITZ are theContents.10–11|8 – 9| Pumps for industry|Pumps for industry10 –Pumps for mining 9or water supplyPumps fo 6 – 7 | PumS.

This raises the question as to whether the concept of the continuous shaft is still up to date. For example, assembly and disassembly of a pump with a continuous shaft requires a large number of individual steps – time-consuming work by an expert! Logistics and warehousing for numerous different component parts is also associated with high costs. Adaptation to changing heads is generally only possible by replacing the pump – a cost-intensive procedure. The problem is obvious. But so is the solution!The solution.MS-T – Modular Shaft Technology is not only a technological evolution, but also a revolution when it comes to costs.MS-T is designed according to the modular principle – with all of its technical and economic advantages.Q Flexible adaptation to changing pumping conditions – quick and easy byincreasing or reducing the number of stages.Q Simple, time-saving and targeted installation and removal of individual stages,horizontal or vertical as desired.Q A small number of highly-standardised components guarantees high availabilityand short delivery times, as well as low warehousing costs on the part of the user.That is why pumps with MS-T are the perfect solution wherever extremely high demands are placed with regard to operational reliability, freedom from mainten-ance, service life, effi ciency and fl exible heads. In all sectors of water supply, mining and industry.MS-T. Designed to save costs.Complete information is available in our brochure “MS-T – Modular Shaft Technology”, which we would be happy to send you on request.Telephone +49 (0) 71 71/60 90 or under www.ritz.de18 | 1910007005003002001005001000200030004000100305005001000100020005000800020005000700050100[I/s]200500[m³/h][ft]20050010002000[m][US.gpm][Imp.gpm]Well Ø 20" and up Q up to 2,000 m³/h H up to 1,500 m p up to 150 bar t up to +75°C n up to 3600 rpmType:Multi-stage, double-suction submersible motor pumps.Areas of use:Mining, water supply and industry.Media:Pure, slightly polluted and abras-ive raw water, pure water, mineral water, seawater, service water, mine water and cooling water.Special feature: Axial thrust free,double-suction design for particularly long service life and high operational reliability.Materials:grey cast iron, bronze,aluminium bronze, duplex stainless steel Shaft seal:mechanical seal, shaft sealing ringImpeller design: radial impeller Types of installation: U (vertical,horizontal)HDMDesign 61 | 67 | 68HDM. Double-suctionsubmersible motor pumps.Maximum operational reliability. Constant performance – error-free operation: An HDM invented by RITZ guarantees maximum operational reliability with no compromises.High cost-effectiveness. Extremely high effi ciency in operation – up to more than 85 percent for the pump, up to more than 90 percent for the motor – as well as extraordinarily long service life ensure minimum life-cycle costs, which are more decisive than the procurement costs in the long term.The challenge.The use of submersible motor pumps for large volumes or at very large depths is associated with extreme loads on the unit. The higher the pump capacity, the stronger the axial thrust exerted on the pump, the motor and its thrust bearing. The outcome: Overloading and increased risk of failure.The solution.HDM – Heavy Duty Mining. Two pumps are arranged on top of each other rotating in opposite directions and driven by a continuous pump shaft.The division of work between the two pumps provides complete compen-sation of axial thrust, thus solving the problems of forces acting on the unit and of the load on the thrust bearing. At the same time, the fl ow and suction velocity outside the pump is reduced by 50 %. This is more gentle on the well walls around the intake openings and minimises the intake of abrasive substances.The result.Besides the technical advantages – complete compensation of axial thrust, 50 % lower fl ow velocity and smaller-diameter impellers – HDM also provides economic benefi ts: maximum operational reliability, minimum wear and extremely long service life, which can quite often exceed 20 years. Paired with the ideal drive – the RITZ high-performance submersible motor – an unbeatable team!Custom-tailored solutions.Each RITZ submersible motor pump with HDM technology is a custom-made item. It is individually confi gured to suit your requirements.Complete information is available in our brochure “HDM – Heavy Duty Mining”, which we would be happy to send you on request.

Submersible motors.The challenge.The effi cient and cost-effective cooling of submersible motors has long been a hot topic among operators of wells and mines. “Derating” was, and still is, a makeshift solution. But besides the higher investment and energy costs, these oversized, derated motors generally require a larger well diameter. Oil cooling is also questionable in many ways – any defects pose the risk of devastating ecological consequences.The solution. MC-T – Modular Cooling Technology, an intelligent, compact cooling system that lays all of these questions to rest. Here a pump impeller creates motion in the cooling circuit, ensuring fl ow in the proper direction. Cooling channels developed in-house by us guarantee heat absorption from all of the thermal sources, ensure evacuation, and provide optimal heat transmission via the outer wall of the motor to the medium being pumped. The cooling performance can be dimensioned precisely through the use of additional heat-exchanger modules.Technical details and economic advantages.Designed for highest temperatures.Designed for slim deep wells.Q Media temperatures up to 75 °C Q High effi ciency over theentire performance rangeQ Use of drinking water as thecooling fl uidQ Low investment costsQ Reduced energy costs Q Maximum operational reliability Q Long service lifeMC-T – Modular Cooling Technology.The challenge.The deeper the well, the greater the required motor power, and the greater the well diameter. This formula represents a headache for all cost-conscious well operators – all of them, in other words!The solution.MP-T – Modular Power Technology, a new motor technology that achieves about 100 % more power for a given well diameter. This means that slimmer, more cost-effective wells can be implemented. The modular principle allows multiple staging of the motor power, which can be dimensioned to suit the user’s individual requirements.In short:RITZ has redefi ned the performance limits of submersible motors.
