Back plate is the part of the pump which fits with the
bearing housing with the help of bolts.Back plate consist
of gland ring towards bearing side where mechanical seal or
gland packings are arranged in such a way that handled
fluid by the pump can be protected from leaking in
atmosphere.Other end of the back plate is towards impeller
which becomes one of the wall in between the suction
casing.Potential energy of Sucked liquid will be turned to
kinetic energy by the high speed rotaion of impeller,during
this operation sucked liquid will be filling the close
clearance in between backplate and impeller which helps in
incresing of pressure.
Back plate has wear ring in its id which has nearly 0.1 mm
clearance with the wear ring on impeller which helps in
preventing the back flow of the discharge to suction and
increases the efficiency.

Answer / dhruv

THE BACK PLATE OF THE CENTRIFUGAL PUMP IS THE MECHANICAL
SEAL HOLDER AND WHERE THE PRESSURE MORE THEN THE OPERATING
PRESSURE DEVELOPS WITH THE HELP OF FLUSSING FLUID TO
PREVENT THE OPERATING FLUID FROM LEAKAGE.

hi ankur

what i have asked and what u r telling.
i am asking what is back plate and its purpose
okey
if u know then give the correct answer
and who has given this answer is yes useless fellow

Answer / dhananjay

Back plate is the part of the pump which fits with the
bearing housing with the help of bolts.
The back plate is of pressed steel manufacture, which together with the pump casing form the actual fluid chamber in which the fluid is transferred by means of the impeller.

Answer / ibrahim

The backplate is of pressed steel or any rigid material, based on application. This backplate and pump casing together form an actual pump liquid chamber where the fluid is undergoing the process.

hi Dhruv
ur answer is not clear

Answer / ankur

as we know that , centrifugal pump is that hydralic pump
which is to convert kinetic energy into pressure energy so
for this purpose their is a impeller on which backward
curved vanes are designed having goes on increasing aera
that rotate tha water and creat kinetic energy &then it
converted into into preser energy.
