Head Range Maximum 740 mater
Maximum sand content into the water:
50 g/m3
GENERAL
- Curves tolerance according to ISO 9906 Annex A The performance curves show pump performance at actual speed of standard motor range.
- The speed of motor is approximately:
- 4″ Motors: n = 2870 min-16″ Motors: n = 2870 min-1 8″ Motors: n = 2900 min-110″ Motors: n = 2900 min-1
- Test result with clean cold water, without gas content. The measurement were made with airless water at a temperature of 20° C.
- Head and Power values valid for liquid with density = 1kg/dm³ and kinematic viscosity V= max 1 mm2/s (1 cSt)
- When pumping liquids with a density higher than that of water, motors with correspondingly higher. outputs must be used
- The QH curves apply to a rated motor speed of 2900 min-1
- The performance curves are inclusive of possible losses such as non-return valve losses
- A safety margin of +2 feet is recommended for the NPSH value
MP CURVES
- Q/H: The curve is inclusive of valve and inlet losses at the actual speed.
- Operation without non-return halve will increase the actual head at nominal performance by 0.5 to 1 mtr.
- NPSH: The curve is inclusive of suction interconnector and shows required inlet pressure
- Power curve. The power curve shows pump power input at the actual speed for one stage.
- Efficency curve np% show pump stage efficency
