SS Submersible > 4″ Submersible Pumps 2m³/h
Have Question?
Point Stainless steel Submersible Pumps are ingeniously designed and developed employing latest engineering softwares, high-tech machinery of pumping technology to deliver the best possible hydraulic efficiency . All these pumps are made of corrosion resistance Stainless steel with Non return valve. These pumps are made by High quality AISI 304 / AISI 316 grade stainless steel.
The 4″ Stainless steel Submersible Pumps discharge range from 0.4m³/hr to 18m³/hr and Head range from 4.0m to 520m. The 4″ Stainless steel Submersible Pumps are available with 1 ¼”, 1 ½” & 2″ Outlet Size.
Point Stainless steel Submersible Pumps are used for Public water supply, Irrigation, Fountains, De-watering, Sprinkler systems, Industrial water supply and Pressure boosting systems.
Features of Point Stainless steel Submersible Pumps: Stainless steel impellers and diffusers to resist corrosion, Built in non-return valve to protect the pump against water hammer, highly efficient, good resistance to sand, Energy efficient hydraulic design for cost effective operation, Easy to install and dismantle for service in the field if necessary .
Pumped Liquids
Non-aggressive, non-explosive, pure, cold, fresh water without abrasives particles having the following characteristics.
| Temperature | 91.4 F |
| Chlorine ion density | 500 ppm (max.) |

6″ : PS6S – 30, PS6S – 48 and PS6S – 60
Connection
Screwed pipe connection with BSP thread as standard
NPT thread pipe connection are avilable on request
Curved Conditions
The conditions below apply to the curves shown the following pages.
Common
- Tolerances in accordance with ISO 9906, Annex A.
- Test Results with clean cold water, without gas content. Measurements have been made with airless water at a temperature of 20oC
- Head and power values valid for liquids with density p = 1,0 kg/cm3 and kinematic viscosity v = max 1 mm2/s (1cSt)
- When pumping liquids with a density higher than that of water, motors with correspondingly highter outputs must be used.
- The QH curves apply to a rated motor speed of 2900 rpm.
- The performance curves are inclusive of possible losses such as non-return valve losses.
- A safety margin of +0.5m is recommended for the NPSH range
4″ & 6″ Curves
- QH : the curves are inclusive of valve and inlet losses at the actual speed
- Power curve : the power curve shows pump power input at the actual speed for one stage.
- Efficiency Curve : n% shows pump stage efficiency.
Operating Conditions
| Liquid temperature | 0o to + 45oC |
| Max. sand content into the water | 50g/m3 |
| Max. starts per hour | 30 at regular intervals |
| Direction of rotation | Clockwise as seen from the pump coupling side. |
Impeller / Diffuser
These pumps are made with SS impeller and Diffuser for high efficiency and less loss. Impellers and Diffusers are avilable with various material grades like AISI 304 / AISI 316.
Shaft
Stainless steel pump shafts are designed and made of AISI 304 / AISI 431 grade Stainless steel material.
Non return Valve with body
The integral Non return valve prevents back flow and reduces the risk of water hammer which paves the way for trouble free performance. Non return valve available with various material grades like AISI 304 / AISI 316.Suction Housing
Suction housing are designed & manufactured in investment casting with various material grades like AISI 304 / AISI 316.
Wearing Ring / Intermediate Bush
The wearing Ring and Intermediate bush are made with high quality rubber like NBR which has less wear and tear resistance.
Strainer
Strainers are provided in the inlet which prevent the oversized particulars entering inti the pump.Reliability
Reliability is ensured by means of high material standard and process methods. Pump parts are made up of stainless steels. These can withstands high abrasive and corrosive environment. Bush bearing and other rubber components are also designed to withstand sand abration and erosion.
Technology – Pump
The technology of submersible pumps are multistage single suction centrifugal type and provided with integral check valve which can be coupled to a submersible electric motors. The submersible pumps are designed and manufactured to provide smooth and easy installation.
Point submersible pumps can be offered with either Point water filled submersible motors or other NEMA standard motors.
The pump is checked during each stage of the assembly process up to the final stage, where in every pump is checked for flow, pressure, power consumption and leaks.
Material Options
The submersible pumps are available in stainless steel AISI 304 and AISI 316 grade in 4″ and 6″ submersible pumps.
| Pump shaft | AISI 304 & AISI 431 |
| Diffuser casing | AISI 304 / AISI 316 |
| Impeller | AISI 304 / AISI 316 |
Efficiency
To make a positive impact in the pump efficiency level effective measures have been taken in designing every component. Superior manufacturing methods are adopted to achieve higher efficiencies.
Durability
The best material, high quality manufacturing methods and rigorous safety tests are conducted to ensure superior strength and durability of each product range.
