IS series high flow horizontal centrifugal water pump electric
power diesel engine
1. IS type single-stage single-suction centrifugal pump according
to international standard ISO2858 specified performance and
dimension design, mainly IS composed of pump body, pump cover,
impeller, shaft, sealing ring, shaft sleeve and suspension bearing
see, etc.
2. IS type single-stage single-suction centrifugal pump pump body
and pump cover parts, from impeller back place subdivision, what
say normally namely after the doors open structure. Its advantage
is easy to check and maintain, repair without acting pump body,
suction line, discharge line and motor, need to remove the extended
coupling among connection parts, can exit rotor parts maintenance.
3.Pump shell (i.e., pump body and pump cover) constitute a pump
studio. Impeller, shaft and rolling bearing for pump rotor.
Suspension bearing components supporting the pump rotor part,
rolling bearing by pump radial force and axial force.
4.In order to balance the axial force of pump, most of the pump
impeller, before and after are equipped with sealing ring, and in
the impeller HouGaiBan the balance hole, because some pump axial
force is not big, impeller back did not set sealing ring and
balance hole.
5. Pump axial sealing ring is by the packing gland, packing ring
and packing, etc, in order to prevent the air intake or a large
number of water leakage. Pump impeller if there is a balance, is
equipped with soft packing cavity and impeller inlet are
interlinked, such as impeller entrance liquid in the vacuum state,
then easily along the shaft sleeve surface intake, so in the
packing chamber are equipped with packing ring through the pump
cover holes, will pump indoor pressure water lead to packing ring
to seal. Pump impeller if not balance hole, because impeller back
liquid pressure is greater than atmospheric pressure, therefore
does not exist gas leakage problem, so don't pack packing ring.
6. To avoid axis wear, in shaft through the packing chamber with
shaft sleeve parts of the protection. Bush and between shaft must
have type O ring, in order to prevent along with surface intake or
leakage.
7. Pump drive way is through the extended elastic coupling and
motor coupling, pump rotation direction, from driving end see, for
clockwise.

Remarks:
1. each model has different flow rate and head lift.
2. each model has different type impeller: A, B, C type impeller.
3. each model could coupled with 2poles or 4 poles motor by
coupling, and also could driven by diesel engine.
