CONSTRUCTION
Horizontal end suction, free shaft end centrifugal pump, two or more stages, composed of :
- Suction cover;
- Intermediate guide blade diffusers;
- Volute pump casing;
- External tie-rods for suction cover and diffusers fastening to pump casing;
- Closed type impellers;
- Bearing stand.

Suction port: axial;
Discharge port: radial, top-directed with the possibility, on request, to be horizontally positioned by 90 on both sides.  Two impeller  wear rings, easily replaceable, are lined in the pump casing and in each diffuser.
The shaft is loaded by large-size bearings, housed in bearing stand and oil lubricated; shaft of three of more stage pumps, is guided by an additional bushing housed in the suction cover.
Adjustable packing-seal, easily replaceable, housed in the stuffing box contained in the pump casing ; through the packing, the shaft is protected by a polished hard-chromium hard-facing or by a chromium-plated sleeve.
A heavy-duty bearing stand supports by overran brace the wet assembly and at the same time, is the setting base; for three or more stages pumps a suction end foot support is provided.

APPLICATION
Water supply for domestic
Industrial and agricultural uses
Municipalities
Fix or mobile rain-irrigation schemes
Fire-fighting equipment’s
Pressure boosting plants

USE LIMITS
Standard construction MEC-MR pumps are suitable to handle fresh water, free from mechanically and chemically aggressive contents.  Temperature of the pumped liquid: -4 F/+ 194 F
Maximum content of suspended solids, with hardness and granules of silt: 40 gr/m3
Coaxial driving only, by flexible coupling or carbon shaft.

TOLERANCE
Given specifications relate to cold water (15 C) at a pressure of 1 bar (atmospheric) and are guaranteed, as for all series pumps, according to ISO standards 2548 class C.
On demand, pumps can be tested according to ISO 3555 class B.
