SELF PRIMING PUMPS TYPE: ‘AO’
|
 |
-
Tolerance of capacity±
10% at rated
head and rated RPM.
-
Discharge indicated in the selection
chart apply to water barometric height of 760 mm mercury column and
at a temperature of 300C.
-
Power indicated is that absorbed at
the pump shaft when pumping liquids having specific gravity of 1.0 and
viscosity of 1 CST.
-
Maximum permissible speed is 1800
RPM.
-
For standard execution maximum permissible
temperature of the liquid is 600C. Hot water construction (designated
by ‘H’) is also available for liquids with temperature between 600C.
|
-
For hot water pumps capacity will be
reduced by approximately 10%.
-
Direction of rotation – clock wise seeing
from the drive end. Reverse rotation (designated by ‘RR’) also available
on request.
-
Maximum suction lift is 8
meters. (Including
friction losses) depending pan the duty point. Capacity reduces over
4 M. suction lift.
-
Before starting valves on suction and
delivery sides must be opened.
- Before starting the pump for the first
time it must be filled with liquid to ensure priming. No
subsequent external priming is necessary.

Tolerance on capacity ± 10% at rated RPM.
Capacity applies to liquid at barometric
height of 760 mm mercury and at a temperature of 300C.
Power inputs indicated above are for
specific gravity of 1.0 and viscosity of 1 CST.
For hot water pump ‘H’ capacity is
reduced.
For suction lift of more than 4 M.
capacity is reduced.
