VERTICAL PUMPS FOR ABRASIVE LIQUIDS

SPUTNIK
PUMP WITH DIRECT COUPLING

Special pumps designed and studied for the conveyance of highly abrasive liquids deriving from stone processing (laboratories and sawmills), from the treatment / washing of aggregates, from the recovery of cement water and in the glass and ceramic processing sectors.

Vertical axis with sealed chamber bearings sized in such a way as to allow the lower part of the shaft to work cantilevered without supports immersed in the liquid.

The bodies are divided into two halves and coated in a special anti-abrasive molded compound (consisting of replaceable and adjustable shells from the outside) The impeller is open-type anti-clogging consisting of a metal core in steel coated with an anti-abrasive compound.

It is possible to apply, on specific request, an extension between the strainer and the lower body in order to increase the maximum immersion height of the pump in order to avoid contact between the liquid to be pumped and the lower bearing (or keep the electric motor out of the tank / well).

Direct coupling to the motor by means of a two-piece elastic coupling.

TECHNICAL SPECIFICATION

AXLE
Vertical pump axle with sealed chamber bearings dimensioned in such a way as to allow the lower part of the shaft to operate without supports immersed in the liquid.

COUPLING
Two-piece flexible coupling complete with protection casing.

BODY
Made of cast iron divided in two halves with protective coating in our special moulded wear-resistant compound, consisting of replaceable shells that can be adjusted from the outside, both to allow rapid and convenient replacement and to eliminate any play caused by normal wear.
In the smaller series the bodies are vulcanised, with shells only on customer request.

DELIVERY CURVE
With interchangeable rubber sleeve for connecting the pump to the delivery pipe.

IMPELLER
Open-type anti-clogging, consisting of a steel core coated with a special anti-abrasive compound.

PUMP STOP
Bracket for fixing the pump to the wall.

PUMP EXTENSION
On specific request, it is possible to insert an extension between the sucker and the lower body in order to increase the distance between the lower bearing and the liquid level, or to allow the electric motor to remain outside the tank.
