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 .

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 20^oC
• 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.
