Vertical Multi-Stage Close Coupled PumpsMXV-BMXV-BConstructionVertical multi-stage close coupled pumps with suction and deli-very connections of the same diameter and arranged along thesame axis (in-line).

All parts that come into contact with the liquid, including wet-endcovers, are in chrome-nickel stainless steel with corrosion-resistant bearing sleeves lubricated by the pumped liquid.

ApplicationsFor water supply systems.For clean non-explosive liquids, without solid, filamentary orabrasive matter and non-aggressive for stainless steel (withadaptation of sealing materials on request).A universal pump for civil and industrial use, for pressure-boo-sting systems, fire-extinguishing systems, high-pressurewashing plants, irrigation, agricultural uses and sport instal-lations.

Operating conditionsTemperature of liquid: from -15 C to +90 C.

Operating environment temperature: up to 40 C.

Maximum permissible pressure in pump casing: 16 bar.

Motor2-pole induction motor, 50 Hz (n = 2900 rpm).

MXV-B: three-phase 230/400 V 10% up to 3 kW;400/690 V 10% from 3,7 to 7,5 kW.

MXV-BM: single-phase 230 V 10%,

with thermal protector.

Capacitor inside the terminal box.

Insulation class F.Protection IP 54.Classification scheme IE2 for three-phase motors.Constructed in accordance with: EN 60034-1, EN 60034-30.

EN 60335-1, EN 60335-2-41.

Special features on request- Other voltages.- Frequency 60 Hz.- Protection IP55.- Special mechanical seal- Pump casing seal rings in FPM.- Higher or lower liquid or ambient temperatures.- Flanges to screw, in chrome-nickel steel.

Wider Range of ApplicationAll parts that come into contact with the liquid, including wet-end covers, are in

chrome-nickel stainless steel.

With corrosion-resistant seal rings and guide ring.

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 ReliableThe 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.
