Every pump manufactured by ETEC reflects its extensive experience providing solutions for massive water movements. ETEC develops pumps with high standards of reliability and durability, while maintaining unmatchable efficiency levels even when operating under the toughest conditions. |
1) The Radial water In-take permits a gradual acceleration of the water coming into the pump, resulting in highly improved efficiency and a reduction in the required submergence.
2) The Impeller is fabricated with cast profiled stainless steel blades for high efficiency. The angles of the impeller blades and the fixed paddles are adjusted to the exact TDH dynamic height of pumping
3) The water lubricated pumps have a Stainless Steel shaft supported by marine brass-rubber bushings lubricated by pumped water; exchangeable stainless steel sleeves installed on the shaft protect it from premature wear.
ETEC assists every user of its pumps in a step-by-step process to implement the right design for the pump station and complementary constructions, to guarantee the best performance of the system. |

| 1. |
Pump body fabricated with marine ASTM-131 Grade-A steel plates.
|
| 2. |
The impeller is fabricated with cast profiled paddles in stainless steel, the paddles are designed with the best hydraulic profile.
|
| 3. |
Stainless steel wear-protection ring with electrolytic isolation avoiding wear on the pump's surface next to the impeller.
|
| 4. |
Built-in Heat Exchanger optimizes output and efficiency in Diesel engines by replacing the Radiator.
|
| 5. |
The water lubricated pumps have Stainless Steel shaft supported by marine brass-rubber bushings lubricated by pumped water;
|
 |
Optional: The shaft is lubricated by oil for operations where abrasive particles or strange objects exist in the water. The shaft is supported by a high resistance bronze bushing, Everything is submerged in oil, retained by a mirror type seal. |
Protection Treatment
Sand Blasting, to achieve the norm SSPC-SP5, or "white metal" of all the metallic parts.
Inside and outside application of rust free, extra thick epoxy paint, and inside and outside application of two coats of Epoxy tar paint to complete 12 mils (average certified thickness)
Installation of zinc sacrifice anodes, welded to the body of the pump to protect it against galvanic corrosion in marine applications.
