PERFORMANCE RANGE
Design Features:
Ø
Pump Casing
The casing
is back pull-out design to allow pulling out the internal components (rotating
parts) for inspection and/or replacement without disturbing the pipe work. The
volute is made of fine- grain cast iron as per ASTM A48 specification equipped
with integrated support feet.
Ø
Impeller
Enclosed,
single suction type cast in one piece. The impeller is dynamically balanced to
ISO1940 and hydraulically balanced through the thrust holes on impeller
suction. The impeller is keyed to shaft and held in lateral position between
the sleeve and the nut.
Ø
Wearing Rings
The pump is
fitted with renewable type casing and impeller wearing rings to maintain proper
running clearance and to minimize the leakage between the suction and discharge
chambers.
Ø
Shaft Seal
TWINNER SYSTEM®
sealing is made of soft-packed stuffing box with graphite impregnated rings.
The gland is made of two halves that greatly facilitates the replacing
operation of the soft packing without the need to disassemble any component.
The stuffing box is fitted with lantern rings to improve the cooling and
lubrication of the shaft
