SUBMERSIBLE PUMPS1.00.00 SCOPE

1.01.00 This specification covers general requirements in respect of design, material, manufacture, construction, testing & inspection at Vendor's / sub-vendor's delivery to side, of submersible pumps.

2.00.00 CODES AND STANDARD

The design manufacture and performance of submersible pumps shall be comply with all currently applicable statues, regulation, and safely codes in the locality where the Equipment will be installed. The Equipment shall also conform to the latest applicable Indian standards listed below other Nation Standards are acceptable, if they are established to be equal or superior to the listed standards. Nothing in these specifications shall be construed to relieve the contractor of this responsibility.

2.01.00 List of Applicable Indian Standards

IS:8034 - Submersible pumps for clear cold fresh water

IS:5120 - Technical requirement of Rotodynamic Special Purpose pumps.

In case of any contradiction with aforesaid standards and the stipulations as per technical specification as specified hereinafter the stipulation of the technical specification shall prevail.

3.00.00 DESIGN AND PERFORMANCE REQUIREMENTS

a) The pump shall be of single stage mono - block type with non-clog design.

b) Components of Identical pumps shall be interchangeable.

c) Pumps shall have a continuously rising head characteristic.

4.00.00 MOTOR RATING

Continuous motor rating (at 50 deg. C ambient) for pumps shall be at least ten percent (10%) above the maximum load demand of the driven equipment in the complete operating range to take care of the system frequency variations.

5.00.00 FEATURES OF CONSTRUCTION

a) Pumps shall be of Submersible, wet pit type.

b) Pumps shall be able to pass through solids upto 40 mm and capable of handling waste water which may contain, sludge, plastic solids etc.

c) Coupling device shall ensure leak proof joint between the pump and discharge elbow. This shall also enable pump to be removed from the sumps without the necessity of dismantling any nuts, bolts etc.

d) Pumps shall be portable type and capable of using in any sump as and when required. Pump shall be provided with required stool, flexible, hoses chain connection etc. for easy installation, removal and maintenance. Adequate length of chain required for lowering the pump into the sump and flexible type discharge pipe shall be provided.

e) Impeller

Impeller type shall be open/semi-closed type/closed as indicated elsewhere. Enclosed impellers shall be equipped with seal rings on their hubs. In case of open impeller, the pump shall be design to take care of the additional thrust produced.

6.00.00 MOTOR

i) Motor shall be coupled directly to the impeller shaft.

ii) The motor shall be suitable for operation when submersed in water. The housing shall have required degree of protection.

iii) Necessary arrangement to be made to make cable entry absolutely water tight, with cores cast in insulation along with cable gland 'O' ring seat.

iv) Built in temperature sensors are to be provided to enable tipping of motor if temperature rises above the design temperature limit. These sensors are to be used directly in the circuiting of control panel. The control circuit should trip the motor if the temperature rises beyond safe limits.

v) Moisture sensors are to be embedded in motor chamber to trip the motor in case of moisture entry in motor due to failure of pump mechanical seal.

vi) Motor shall be oil filled/oil lubricated or water filled type. Pressure equalizing diaphragm and sand guards with seal shall be provided to prevent the water and sand entering the motor.

vii) Power supply to the motor and control connections shall be preferably combined in one cable and shall be flexible copper conductor PVC insulated, armored and overall hard grade PVC sheathed, and suitable for under water service. The cable gland shall be properly sealed to prevent entry of pumped liquid the motor. Length of the cable shall be of suitable for site conditions. The cable shall be terminated on the control panel with necessary facility to terminate with the power receptacle.
