Vertical Multi-Stage In-Line Pumps
Construction
Vertical multi-stage pumps with suction and delivery connections
of the same diameter and arranged along the same axis (in-line).
Corrosion-resistant bearing sleeves lubricated by the pumped liquid.
A pump with thrust bearing and sleeve coupling for use of any
standard motor with V1 construction.
Applications
For water supply systems.
For clean non-explosive liquids, without solid, filamentary or
abrasive matter (with adaptation of sealing materials on request).
A universal pump for civil and industrial use, for pressure-boosting
systems, fire-extinguishing systems, high-pressure washing
plants, irrigation, agricultural uses and sport installations.
Operating conditions
Temperature of liquid: from -15 °C to +110 °C.
Operating environment temperature: up to 40 °C.
Maximum permissible pressure in pump casing: 25 bar.
Motor
Standard-type: 2-4 pole induction motor, 50 Hz.
Classification scheme EFF2 or EFF1 (High efficiency) on request.
Construction IM V1 (EN 60034-7).
Insulation class F.
Protection IP 55.
three-phase with rated voltage: up to 3 kW 230/400 V;
from 4 kW 400/690 V.
Rated speed of rotation (50 Hz):
MXV = 2900 rpm
MXV4 = 1450 rpm.
MXV 25-2, 32-4, 40-8
MXV 50-16, 65-32, 80-48
Materials (wetted parts)
Materials (wetted parts)
All parts that come into contact with the liquid, including wet-end
covers, are in chrome-nickel stainless steel AISI 304.

Vertical Multi-Stage In-Line Pumps
Features
Long Service Life with Standard Motor
Pump with thrust bearing without additional axial loads on the motor
bearings.
Any standard motor V1 design (suitable to be lifted in vertical position) can be used, of our choice or of Clientʼs choice.
Easy Assembly of the Motor
With 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 Safety

Single-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 Installation
3.93.029
Vertical 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 Reliable
Single 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.

Vertical Multi-Stage In-Line Pumps
Features
Long Service Life with Standard Motor
Pump with thrust bearing without additional axial loads on the motor
bearings.
Any standard motor V1 design (suitable to be lifted in vertical position) can be used, of our choice or of Clientʼs choice.
Easy Assembly of the Motor
With 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.

Low Cost Installation
3.93.029
Vertical 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 Reliable
Single 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.
