Deep well hand pumps
summary
Deep well hand pumps are manually operated water lifting devices designed to draw groundwater from deep borewells, typically exceeding shallow depths. They are widely used in rural and remote areas for drinking water supply. These pumps are durable, corrosion-resistant, and designed for long service life.
Why BIS Certificate is Mandatory for Deep well hand pumps
BIS certification is mandatory to ensure deep well hand pumps meet prescribed standards for safety, durability, performance, and public health protection. Since they are used for drinking water supply, compliance with BIS prevents substandard materials, structural failures, contamination risks, and ensures reliable operation in rural water supply schemes.
What is BIS Certified for Deep well hand pumps
The BIS certified specification for deep well hand pumps defines requirements for materials, dimensions, performance parameters, corrosion resistance, galvanization, mechanical strength, and testing methods. It ensures pumps are suitable for potable water use, long-term operation, and compliance with Indian Standards for rural water supply applications.
