MXVMXV Vertical Multi-Stage In-Line Pumps
Pumps with frequency converter
The MXV EI pumps are available with power from 0,25 kW up to 11 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 0,25 kW to 11 kWControl range from 1750 to 2900 rpm (2-pole) Control range from 870 to 1450 rpm (4-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 by the installa-tion changes.
Proportional pressure mode with pressure sensor
In this mode the system changes the working pressure according to the required flow rate.
Constant flow mode with flow meter
In this mode the system maintains a constant flow rate value in a point of the installationaccording 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 operational curveincluded within the working range.
Constant temperature modewith temperature transducerIn this mode the system keeps the temperature constant inside a system by changing thespeed 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 posi-
tion) can be used, of our choice or of Client’s choice.
Easy Assembly of the MotorWith the single-piece sleeve coupling the pump unit can be supplied
fully assembled also without the motor. This eliminates the risk of
damage caused by shifting of the pump shaft during transportation.
The motor is simply inserted in the coupling and fastened to the
flange without the necessity for adapting the axial position of the
pump shaft.
Extra SafetySingle-piece coupling guard to be removed only by means of a tool,
positioned around the lantern bracket, thus avoiding accidental
pushing and rubbing against the coupling.
Low Cost InstallationVertical construction with reduced pump height for installation in
small spaces.
In-line connections to simplify the piping layout with the possibility
of inserting the 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 piping on the pump without the creation of distorting loads
causing local friction and early wears.
The lantern brackets compact and robust design maintains a sure
alignment between 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,
work together for low-noise operation.
Low-noise standard motor.

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 posi-
tion) can be used, of our choice or of Client’s choice.
Easy Assembly of the MotorWith the single-piece sleeve coupling the pump unit can be supplied
fully assembled also without the motor. This eliminates the risk of
damage caused by shifting of the pump shaft during transportation.
The motor is simply inserted in the coupling and fastened to the
flange without the necessity for adapting the axial position of the
pump shaft.
Extra SafetySingle-piece coupling guard to be removed only by means of a tool,
positioned around the lantern bracket, thus avoiding accidental
pushing and rubbing against the coupling.
Low Cost InstallationVertical construction with reduced pump height for installation in
small spaces.
In-line connections to simplify the piping layout with the possibility
of inserting the 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 piping on the pump without the creation of distorting loads
causing local friction and early wears.
The lantern brackets compact and robust design maintains a sure
alignment between 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,
work together for low-noise operation.
Low-noise standard motor.
