Solar Dual Pumps

The solar dual pumps is an innovative pump designed to utilize the power of the sun during the day and act as a normal hand pump when the solar energy is not available, hence assuring uninterrupted water supply for drinking, sanitation, personal hygiene etc. The system consists of a submersible pump which runs on power generated from the photo-voltaic solar cells and is suitable for use on bore-wells with 100 mm (and above) diameter up to 80-90 meters depth. In practice a solar array is installed near the bore-well, a submersible pump powered with DC motor is installed below the hand pump cylinder. The pump is connected to a storage tank and the collected water is dispensed through a stand post. This system can also be used on other water sources such as open wells or tanks.

Solar Pumps

A Solar Pump is designed to utilize the direct current from the array efficiently, even as the energy production varies throughout the day. Solar Pumps suggest a clean and uncomplicated substitute to fuel-burning engines and generators for domestic water, livestock and irrigation. They are most efficient during dry and sunny seasons; require no fuel deliveries and needs very less safeguarding. They are powered by photo-voltaic panels (not a single battery is used) and the flow rate is determined by the intensity or radiation of sunlight. Thus the Solar Power Pumps are more cost-effective and have not as much of impact on the environment than the pumps operated by the combustion engine.

Joy Pump

Joy - See Saw Pumps

Joy pumps are an innovative concept of pumping water from bore-well, a sump or a rainwater harvesting tank. It uses playful energy of children or operators collectively to pump water. See Saw pumps use force lift technology to draw water from a water source to an overhead tank above the ground level for storage and distribution. It doesn’t require electric power. See Saw pumps work on the same technology and use the reciprocating motion to move the valves of a water cylinder. These pumps use a specially designed mechanism to convert the revolving motion to a reciprocating one. The technology below the ground is same as the hand pump technology, hence making it very easy to maintain at village level.

Hand Pumps

India Mark II Hand Pump

The India Mark II hand pumps family was developed as a low cost option for rural water supply program. The pump is specially designed for the prolonged and continual community use in demanding conditions. Besides India, the India Mark II hand pump is used throughout the world in many developing countries including Asia, Africa and Latin America to pump water from deep bore-wells. These pumps are manufactured and supplied conforming to Bureau India Standards IS: 15500-2004. In order to ensure trouble free service in the field, these pumps are manufactured adhering to strict internal quality control system.

India Mark III Hand Pump

The India Mark III VLOM deep well hand pumps’ design evolved to replace the India Mark II in remote locations where special tools were rarely found. Conforming to IS: 15500-2004 standard, India Mark III hand pump has open top cylinder (OTC), which facilitates pulling out of plunger assembly. It also assists in changing valve assembly from the cylinder without pulling out the water cylinder and riser pipes. These pumps are modified versions of India Mark II hand pumps; moreover G.I. pipes measuring 65/50 NB in diameter are used in this pump. Use of the VLOM pump thus reduces requirement of heavy tools, users including women can be trained for the repairs. Hence it is named as (VLOM) Village Level Operation Maintenance pump.

Afridev Hand Pump

AFRIDEV hand pumps have all the features of VLOM hand pumps and additionally it has been designed to overcome the maintenance problems faced by the rural/ unskilled operators, so that woman can easily handle it too.

Force Lift Hand Pump

The various water supply schemes to provide adequate, safe and potable drinking water to the rural & urban masses since last more than 6 decades include open dug-wells, bore-wells & piped water supply schemes. The rural population however prefers less strenuous but expensive piped water supply schemes which however have financial limitations. In order to fulfill the ever increasing demands of rural & urban classes, a low cost Mini Water Supply scheme in the form of Force lift hand pump was developed.
