4. TECHNICAL INFORMATION
4.1. Design
These are double suction, split case, horizontal pumps. Since the upper
cover of the pump is dismountable, all the internal components can easily
be replaced without dismounting the pump case and the fittings.
Stuffing box is cooled with water. Gland is easily dismountable type. In
this way, it is very easy to replace and fit up additional seals. Since the
impeller is double suction type, axial force is balanced automatically. .
4.1.1. Locations Of Flange – Flanges
Pumps have normally clockwise rotation when viewed from the driver
side. In this case, suction opening is on the right and discharge opening
is on the left. Suction and discharge flanges are concentric. Suction and
discharge flanges are in accordance with DIN 2533-PN 16. It is possible
to manufacture pumps with counter clockwise rotation.
4.1.2. Auxiliary fittings
Please refer to the technical drawing of the pump for necessary auxiliary
fittings
4.1.3. Impeller
Specially and carefully designed impellers are closed type and have
Francis type blades. They are balanced both statically and dynamically
