CMV44. Features and benefitsFig. 5CMV pumpsCMV pumps offer the following features and benefits:Compact designPump and motor are integrated in a compact anduser-friendly design.Modular construction/customised solutionsThe modular construction of the CMV pumps makes iteasy to create many different variants based onstandard factory parts. This means that it is possible tocreate pump variants that are customised for theapplication in question.Worldwide usage• CMV pumps are as standard available with singleandthree-phase motors suitable for 50 Hz voltagesupplies. Other voltage and frequency combinationsto cover markets worldwide are available uponrequest.• Various certificates covering worldwide usage areavailable. See 13. Certificates on page 22.High reliability• New state-of-the-art shaft seal design and materialsoffering these benefits:– high wear resistance and long operating life– improved sticking and dry-running capabilities.• The pumps are less sensitive to impurities in thepumped liquid than similar pumps of thecanned-rotor type.TM05 0727 1511Service-friendly• Service was in mind during the development.• No special service tools required.• Spare parts in stock for quick delivery.• All parts available as kits, single parts or bulks.• Service instructions and video make it simple todisassemble and assemble the pump.• Service kit instructions available where estimatednecessary.Low noise levelThe CMV pumps offer very silent operation.High-performance hydraulicsPump efficiency is maximised by the optimisedhydraulics and carefully crafted production technology.Electro-coated cast-iron parts• Optimised corrosion resistance• Better efficiency because of smooth surfaces.Customised solutionsIt is possible to create many different variants of theCMV pump.For further information, see 20. Customisation onpage 33.• Motor adaptation.• Pump body modifications.Grundfos motorGrundfos motors are remarkably silent and highlyefficient.Data and literature about the CMV pumpsAll literature and technical data related to CMV pumpsare available on line in Grundfos WebCAPS.Features and benefitsEasy installation and commissioning• A Quick Guide is supplied with each CMV pump,which enables easy installation and commissioning.Detailed multilingual installation and operatinginstructions are supplied with each pump.• An installation indicator is fitted on three-phasepumps, which makes it easy to see if the electricalconnection of the motor is correct. Based on themotor cooling air, it indicates the direction of rotationof the motor.TM05 0870 1811Fig. 6Installation indicator7
