Self Priming and Mini Monoblock
Pumps |
|
GEW
is the leading manufacturer of finest multipurpose mini self priming and mini monoblock
pumps. GEW has vast experience in the field of presenting Domestic pumps without
any trouble and reliable quality. The highlights of our pumps are compactability,
easy installation and less maintenance. Our special features include continuous
operation, greater efficiencies, extremely quiet operation and high working pressure.
self priming pumps are designed without footvalue. The internal clearances are kept
to a minimum and for this reason these pumpsets are intended for use with clean
water, free from solides, abrasives and fibrous material to get the best possible
efficiency.

APPLICATION : |
|
Used for water supply to Residential Bungalows and Flats.
GEW HSM & HCM models of Self Priming and Monoblock pumps
employ a 240 volts, 50 Hz capacitor start and run, 2880 RPM, TEFC, Prime mover motors
of single phase. All pumps are tested as per IS : 8472 HCM & HSM motor bodies
are made from high quality extruded aluminium. And DMS motor bodies are made from
cost iron, Dynamic balancing of rotor assembly, ensures better life for bearings
and seals. Pump is made up of close grained cast iron casing and Brass forged impeller.
The volute is designed for maximum output. The front end bearing is protected by
a water thrower ring. Sealing is by means of a bellows mechanical seal fitted over
the shaft which is ground to close tolerances.
We ensure consistent quality by testing the pumps thorughly.
We maintain the required quality control norms very strictly. Operator's Manual
is provided for correct installation.

IMPORTANT NOTES :
1. Use ISI mark quality pipes.
2. Proper size of pipes should be installed as specified in name plate.
3. Reduce number of bends and elbows in the pipe line.
4. The monoblock should be run for a few minutes atleast once in 2
days to prevent the pump from seizing due to rust build - up.
5. Muddy water will damage the pump. Use strainer at the bottom end
of the suction pipe.
6. Ensure that the pump does not run dry to avoid damage to mechanical
seal and impellers.
7. Do not throttle the delivery line using a gate valve, as this will
result in overloading of the motor.
8. Do not wrap the pump with air tight materials such as polythene
sheet, because condensation will form in the tightly wrapped motor and winding will
burnout.
9. Read our Operator's Manual carefully before installing the pump.
NOTE:
1. The performance figures given below are based on mean supply voltage
indicated on the name plate.
2. Pipe sizes mentioned in mm are nearest conversion of inches, but
actual pipes threading are provided as per 'BSP' standard.
3. Total Head = Static Suction + Static delivery + Number of pipe bend,
NRV etc.
4. The self priming time depends upon static suction installatoin conditions
and the duration of use of the pumpset.
5. As we are continuously undergoing the R & D work all the above
matters are subject to change without notice.
6. HCM = High Speed Centrifugal Monoblock HSM = High Speed Self Priming
