20l/s underground water submersible pump technical specifications:
1. Pump body
The pump body shall be cast in zinc-free bronze, stainless steel/AISI 316 or cast iron. The body shall be capable to withstand a hydraulic pressure, equal at least to one and a half (1.5) times the shut-off head.
2. Impellers
The impellers shall be cast in high-grade zinc-free bronze or stainless steel. In case of impellers of enclosed type, the bowls shall be equipped with wear rings of renewable type, made of zinc-free bronze and having larger bearing surface, AISI 316 or Thermoplastic Resign armored with Stainless Steel.
3. Shaft
The pump shaft shall be of stainless steel with journals sleeved with renewable, hardened stainless steel sleeves/AISI 420.
4. Bolt and Nuts
All bolts, nuts, studs, washers, etc. shall be manufactured in stainless steel.
The pump shall be fitted with removable shaft bearing sleeves, bearing bushes, casing wear rings and impeller wear rings. Each impeller shall be located on the shaft by identifiable distance sleeves or similar, such that re-assembly of the rotating element can be carried out without the necessity of accurate measurement. The rotating assembly shall be statically and dynamically balanced after which each part of the assembly shall be identified and marked to ensure identical re-assembly after maintenance.
5. Diffuser
Diffuser is made Thermoplastic resin
6. Bearing
Bearings shall be water lubricated and where rubber type bearings are used the bearing material shall be securely bonded to a metal housing. Rubber bearings shall only be used where there is sufficient pressure difference through the bearing to afford adequate lubrication and cooling of the bearing.
7. Stage Casing
Stage Casing is made from AISI 316
8. Motor
The submersible motor shall be of the completely enclosed type for continuous duty under water operation on 400 V 50 Hz, 3 phases AC. Motor performance shall be in accordance with the relevant section of BS 5000:Part 99. The electric motor is Rewindable. Motor Casing is AISI 316
100% of pump units are factory-tested
