- Proper installation of the pump system, including shaft alignment, coupling of motor and pump is a must. Drive transmission between pumps and motors is very important. Loose belts can cause energy loss up to 15 per cent to 20 per cent.
- Use efficient transmission system. Maintain right tension and alignment of transmission belts.
- Use of modern synthetic flat belts in place of conventional V belts can save five per cent to 10 per cent of energy.
- Properly organised maintenance is very important. Efficiency of worn out pumps can drop by 10 per cent to 15 per cent, unless maintained properly.
- Use low friction rigid PVC pipes and foot valves.
- Avoid use of unnecessary bends and throttle valves.
- Use bends in place of elbows.
- The suction depth of six meters is recommended as optimum for centrifugal pumps. The delivery line should be kept at the minimum required height in keeping with requirements.
- Periodically check pump system and carry out corrective measures such as lubrication, alignment, tuning of engines and replacement of worn-out parts.
- Over irrigation can harm the crops and waste vital water resource. Irrigate according to established norms for different crop.
- Use drip irrigation for specific crops like vegetable, fruits, tobacco, etc. Drip systems can conserve up to 80 per cent water and reduce pumping energy requirement.
- Install multi speed motor.
- Optimise operating voltage level of motor for lightly loaded motors
- Provide interlock for electric motor to avoid idle running.
- Replace motor generating sets with thyristor drives.
- Avoid frequent rewinding of motors. Greater the number of rewind, lesser the efficiency.
- Carry out preventive maintenance and condition monitoring schedule regularly.
