MXV EI Vertical Multi-Stage In-Line Pumps

Pumps with frequency converter

The MXV EI pumps are available with power from 0,75 kW up to 22 kW,the pumps are equipped with I-MAT installed on board which allows torealize a variable-speed system extremely compact and efficient, ideal inapplications of water supply and in the distribution of hot and cold water. The pump is equipped with transducers suitable for operation and isalready programmed at the factory.

Advantages- Energy saving- Compact design- Easy to use- Programmable to suit the system requirements- Reliability

CostructionThe system comprises of:- Pump- Induction motor- I-MAT Frequency converter- Motor adapter for the motor mounting of the frequency converter- Connection cable between frequency converter and induction motor- Transducers

Main featuresRated motor power output from 0,75 kW to 22 kWControl range from 1750 to 2900 rpm (2-pole) Protection against dry runningProtection against operations with closed connection portsProtection against system leakagesProtection against overcurrent in the motorProtection agains overvoltage and undervoltage of the power supplyProtection against current unbalances between phases

Mode at a constant pressurewith pressure sensor

In this mode, the system maintains the preset pressure when the flow required bythe installation changes.

Proportional pressure mode with pressure sensor

In this mode the system changes the working pressure according to the requiredflow rate.

Constant flow mode with flow meter

In this mode the system maintains a constant flow rate value in a point of theinstallation according to the required pressure.

Fixed speed mode with setting of the speed preferential rotation.

In this mode, by changing the working frequency, you may choose any operationalcurve included within the working range.

Constant temperature modewith temperature transducerIn this mode the system keeps the temperature constant inside a system bychanging the speed of the pump.

Long Service Life with Standard MotorPump with thrust bearing without additional axial loads on the motor bearings.Any standard motor V1 design (suitable to be lifted in vertical position) can beused, of our choice or of Client’s choice.

Easy Assembly of the MotorWith the single-piece sleeve coupling the pump unit can be supplied fullyassembled also without the motor. This eliminates the risk of damage causedby shifting of the pump shaft during transportation.The motor is simply inserted in the coupling and fastened to the flange with-out the necessity for adapting the axial position of the pump shaft.

Removable mechanical SealEasy removal of the mechanical sealwithout dismantling the motor (for MXV50-15, MXV 50-20 and MXV 100 withmotors exceeding 4 KW).

Extra SafetySingle-piece coupling guard to be removed only by means of a tool, positionedaround the lantern bracket, thus avoiding accidental pushing and rubbingagainst the coupling.

Low Cost InstallationVertical construction with reduced pump height for installation in smallspaces. In-line connections to simplify the piping layout with the possibility of insertingthe pump in straight pipe-lines. Disassembly, inspection or cleaning of internal parts without removal of piping.

Robust and ReliableSingle PN 25 construction for all pump sizes.The suction and discharge nozzles arranged in-line absorb the forces of the pip-ing on the pump without the creation of distorting loads causing local friction andearly wears.The lantern brackets compact and robust design maintains a sure alignmentbetween rotating and fixed parts, reducing vibration.The upper cover design prevents entrapment of air around the mechanical seal.

Low-Noise OperationThe water filled shroud around the stages and thick external walls, worktogether for low-noise operation.Low-noise standard motor.

MXV 50-15, MXV 50-20


ConstructionVertical multi-stage pumps with suction and delivery connections ofthe same diameter and arranged along the same axis (in-line).Corrosion-resistant bearing sleeves lubricated by the pumped liquid.Removal of the mechanical seal without dismantling the motor(for MXVL 50, MXVL 100 with motors exceeding 4 KW).A pump with thrust bearing and sleeve coupling for use of anystandard motor with IM V1 construction.
