NON-CLOG SUBMERSIBLE SEWAGE
PUMPS:
|
| |
Non-clog
submersible sewage pumps offer simple, the most economical
and most reliable way of solving the pumping and disposal
of sewage containing suspended solids “Powerpoint”s
rich experience over several years in the field of designing
and manufacturing of varieties of pump sets has built up
technical know-how and expertise in designing of reliable
and efficient pumps. which need practically on maintenance. These compactly designed pumps are easy to handle and can be installed permanently with the help of automatic
couplings in a small sump from where sewage is to be pumped
or can be used for portable duty. Being submersible they
do not require and pump house. |

Profile Gasket:
|
| |
Ensures flexible, pressure-light
and automatic connectionbetween pump and duckfoot band. |
| |
|
| 8. |
Double Mechanical Seals:
|
| |
All pumps have
as standard equipment double mechanical seals which seal off
the motor from the pump section. The seal has faces made from
silicon carbide for long life. The design of the oil chamber
ensures efficient cooling of the seals. |
|

CONSTRUCTION: |
| |
"Powerpoint” non-clog submersible
sewage plump are of close
coupled compact design and having a pump below and a motor
above,
sump cleaning is possible to a maximum level. These are power
ed by squirrel cage induction dry motors suitable for operation
at 400/400 volts, 3 phase. 50 Hz, Ac supply. Being submersible, they save a lot of costs on construction compared to other
conventional pumps. They also are noice free in operation.
|
| 1. |
Bearings:
|
| |
The bearing arrangements
with double angular contact ball
bearings with deep grove ball bearings give the best resistance
pump. The life rating is over 40000 hrs. The bearing are lubricated
for life with a high temperature grease.
|
| 2. |
Dry, Squirrel cage 3 phase motor:
|
| |
The housing is totally dust
& waterproof for submersible duty.
The cooling is done externally and the special insulation of
the winding takes care of rises in temperature during intermittent
operation. |
| 3. |
Cable Joint:
|
| |
Special triple protection does not permit
any liquid entry into the dry motor
|
| 4. |
Moisture detection probe:
|
| |
The moisture detector
indicates any moisture penetration into the motor.
|
| 5. |
Thermal Motor Protection:
|
| |
Built-in temperature sensors enable tripping of the motor if
the temperature rises above 150 deg.C.and restarts at 80 deg.C,giving
complete dry run protection. Maximum permissible liquid temperature
is 50 deg.C.
|
| 6. |
Guide Device with single/double
guide rail:
|
| |
The guide rail systemfor lowering
and lifting the pump is an outstanding feature. The pump slides
down on to the duckfoot bend and engages with it without bolting. It
is not necessary to enter the sump to carry out inspection
and maintenance work.
|

Energy saving
impellers to suit different applications: |
| |
Depending on the liquid ,impellers
may be semi-open
or closed, running against a wear disc or casing ring.
For industrial sewage, single channel, two channel or
vortex impellers, can be used. |
| |
|
| 10 |
Shaft with rotor:
|
| |
A shaft with a die-cast rotor
on the motor side and a shaft protection sleeve on the pump
side,ensures better life for the shaft. The compact seal arrangement
has minimised shaft over -hang and consequently minimises shaft
deflection. |
| 11 |
The motor portion
is isolated from the pump by an inter mediate casing with double
mechanical seal in the oil chamber. |
|
|
|
|
 |
VORTEX
IMPELLER
Vortex impellers are selected for applications
having long, stringly solids in the pumped liquid or for pumping
solids with high solids concentration |
 |
A vortex impeller creates a wirlpool
or vortex inside the pump volute, solids pass through this vortex
rather then through the impeller. |

|
ROBOTEX
IMPELLER
The special clog-free design of the spiral
vanes impeller makes this pump the first choise for applications
where the key words high efficiency, high suction lifts ,minimum
product damage and low flow disturbance. Mainly used for heavy
& activated sludge. |
 |
 |
|
|
 |
GUIDE
BAR COUPLING:
Guide bar type quick release coupling for
stationery
wet installation .The pump is automatically coupled to
the bend.
IMMERSIBLE:
For stationery installation in a dry sump.Motor
in a flood-proof design with efficient cooling system. Both
for horizontal and vartical installations.
TRANSPORTABLE:
Pump with support and hose adapter for
temporary wet installation. The pump can easily
be moved to other sites . |
|
 |
3.GRINDER
PUMP
For limited quantities of water that
require small discharge pipes. Solids are cut into vary small
particles that can be pumped through these small pipes without
risk of blocking.
|
 |
|
| 4. |
AGITATOR
FOR HIGHEST DENSITY
The agitator which is mounted just below the
intake opening feeds the impeller with high density material. This in combination with the strong vortex created by the
impeller ,leads to unmatched solids concentration. Strong
surface boundaries are mechanically broken, making solids below
accessible for pumping. Oversizes solids are thrown away from
the intake, preventing accumulation of large solids that
would impair performance. |

5. OPEN SINGLE CHANNEL
IMPELLER
In order to achieve the best possible
solids handling performance, the single channel impeller pumps
are equipped with an open single channel impeller running
against an adjustable suction cover. |
 |
6. DOUBLE CHANNEL
IMPELLER
For achieving the highest possible efficiency
the larger channel pumps are fitted with a double shrouded
channel impeller with rubber wear rings.
