MXV 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.
9
Maximum permissible pressure in pump casing: 25 bar.

Motor
Standard-type: IM V1 (IEC 34-7) construction, insulation class F
(IEC 85), degree of protection IP 55 (IEC 529); three-phase with
rated voltage: up to 3 kW 230/400 V (IEC 38);
from 4 kW 400/690 V (IEC 38).
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

All parts that come into contact with the liquid, including wet-end covers, Internal parts in contact with the liquid in chrome-nickel stainless steel,
are in chrome-nickel stainless steel. with pump casing and upper cover in cast iron (in stainless steel on
request).

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 posi-
tion) can be used, of our choice or of Client’s choice.

Easy Assembly of the Motor

With the single-piece sleeve coupling the pump unit can be supplied 34.02
20.00
fully assembled also without the motor. This eliminates the risk of
14.04
damage caused by shifting of the pump shaft during transportation.
36.00
The motor is simply inserted in the coupling and fastened to the 14.02
flange without the necessity for adapting the axial position of the 64.00
pump shaft. 64.15
28.00
25.02
25.03
64.10
Extra Safety
13.60
Single-piece coupling guard to be removed only by means of a tool,
14.54
positioned around the lantern bracket, thus avoiding accidental 16.00
pushing and rubbing against the coupling. 34.01
14.12
3.93.029

MXV 25-2, 32-4, 40-8

Low Cost Installation
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 14.04
of the piping on the pump without the creation of distorting loads caus- 34.02

ing local friction and early wears. 36.00

14.02
The lantern brackets compact and robust design maintains a sure
28.00
alignment between rotating and fixed parts, reducing vibration.
25.02
The upper cover design prevents entrapment of air around the
64.00
mechanical seal. 14.54
64.15
14.42
25.03
Low-Noise Operation 64.10
The water filled shroud around the stages and thick external walls, 14.00
work together for low-noise operation. 14.12

Low-noise standard motor. 14.12
