Description of the HIGH CENTS industrial centrifugal pumps

A range of high capacity low head heavy-duty open impeller centrifugal pumps made from die-pressed stainless steel aisi 316 with capacities up to 84m3 per hour and heads up to 15m sold either as wet end alone; pump and motor; pump and motor and trolley mount. The HIGH CENTS range of pumps mounts standard closed externally ventilated 1400 rpm B3/B5 motors with IP55 protection from 3HP through 7.5HP. The HIGH CENTS pumps are made to ISO 9002 norms.

The HIGH CENTS pumps feature :
*High capacity with 1400 rpm motors.
*Cold die-pressed from heavy duty 4mm thick stainless steel sheet metal for greater mechanical resistance, elimination of vibrations and noise reduction.
*Built entirely from stainless steel aisi 316.
*Reduction of welding procedures to increase simplicity and heighten resistance. The few welds are deeper because of the thickness of the metal and ensure greater reliability.
*Indvidual testing of every pump in conformity with ISO 9002 norms so as to guarantee the best quality and conformity with specifications.
*Open-impellers enabling liquids with solids in suspension to be pumped.
*Availability of trolley mount complete with switch and plug
*Availability of flanges for welding
*Supplied with steel base for simple and rapid installation.
*Single impeller horizontal axis monoblock coupling.
*Standard externally ventilated B3/B5 EEC motors for continuous duty with IP55 protection with an extra protection ring on the motor shaft and a stainless steel back plate separating the pump from the motor.
*Careful internal and external polishing to ensure the highest possible level of resistance to corrosion and optimum hydraulic efficiency.
*Inlets and outlets female gas threaded, or with flanges.
*Choice of mechanical rotative type seals with Viton(R) and Teflon (PTFE)(R) rings.
*Temperature -10 degrees C to + 120 degrees centigrade
*Maximum system pressure 10 bar.

Applications

HIGH CENTS industrial centrifugal pumps are for use with dirty liquids with threads and solids in suspension where traditional pumps cannot be used. The 1400 rpm motors offer the following advantages:
-lower cavitation problems as operating temperatures increase
-better NPSH values
-lower wear and tear of parts and absence of vibration
-gentle treatment of the liquids pumped.

INDUSTRIAL PLANTS

Circulation of liquids including corrosive and abrasive liquids and liquids with solids and threads in suspension in industrial plant, such as, purely by way of example, in the textiles, galvanisation, and water treatment sectors.

ALIMENTARY LIQUIDS

Wine, fruit juices, edible oils, beer, milk products not requiring strictly hygienic pumps (for hygienic sanitary pumps please refer to MILKY WHEY pumps), brine solutions and alimentary liquids generally.

PHARMACEUTICAL LIQUIDS

Wax, liquid soaps, creams, syrups, shampoos etc

LIQUIDS IN THE LIGHT CHEMICALS INDUSTRIES

Starch, water based glues, emulsions, glycerine, glycols, latex, animal and vegetable fats.

Do NOT use HIGH CENTS pumps for:

Aggressive liquids for which the construction materials used are not suitable such by way of example as chloric acid, hydrochloric acid in any concentration, silver chloride, hydrofluoric acid, muriatic acid, sulphuric acid, hydrobromic acid, molten antimony and aluminium, ammonia, sulphur chloride and so on.
Liquids with temperatures over 90 degrees C (viton(R) rings) or 120 degrees C (teflon(R) rings)
In environments where system pressure is higher than 10 bar.

SPECIFICATIONS

Capacity
