Curve

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.

Ideal for pumping of sewage containing stringy materials and rags. Pd series pumps are built with large clearances that allow ample free passages for the pumping of biological sludge wastes.

The 6" stainless steel submersible pumps are made discharge range from 7m3hr to 80m3hr and head range from 4.5m to 550m. The 6" stainless steel submersible pumps are available with 2", 2 ", 3" & 4" outlet size.
