Irrigation, Water & Treadle Pumps
Features: Each treadle pump has two cylinders which are made of engineering plastic. The diameter of a cylinder is 100.5mm and the height is 280mm. The pump has two pairs of non-return valves, one pair inside of the valve box and the other pair outside. These valve flaps are flat and semicircle . They are made of rubber with the diameter of 90mm and the thickness of 2.5mm. The piston is assembled with one piston rod (25mm x 6mm) ,two rubber cups with the thickness of 5.5mm and three steel plates, the bigger plate in the middle and the other two smaller on each top . The treadles are made of channel steel with the length of 1000mm. The hinge is at the end. The treadle support ensures that the pump is portable and supports all other components of the pump and users. It is made of 50mm x 30mm square steel tube. ADVANTAGES 1. It frees the farmer from the limitations of rain fed farming and raises their capacity to grow crops in both dry and rainy season. 2. Cultivate expansive land area: With the use of Treadle Pump, the Farmers can cultivate all the year round thus increasing their cropping intensity, and never leave their land fallow. 3. Productive : The Treadle Pump is capable of delivering 7,000 litres of water per hour from surface water while being operated by a single person without tiring the user. The pump is capable of working up to a maximum depth of 8 meters. However, operation beyond 7 meters is not recommended to preserve the integrity of the rubber components. 4. The farmers can plant more different crops: Treadle Pump technology enables the farmers to plant crops they were not able to plant before. A series of new advantages is brought with the use of plastic pump body: Light weight Small friction, low wear and tear High efficient Good seal Rustless Corrosion-resistant Low price New engineering plastics, firmly and durable

Fitting instruction and Maintenance

  • Cylinder assembly
  • 1. Locating the rubber cup seal into the cylinder; 2. Pushing the piston inside the cylinder 3. Move up & down in the cylinder. Each piston has two rubber cups, one faces to the bottom of the cylinder and the other to the top. The pistons can be removed from the pump without detaching the rope which connects them together. When replacing the pistons, it is important to take care and make sure these rubber cups are not be damaged. And it is important to keep sealed.
  • Assembly of Treadles
  • Connect the end which has hooks with the piston rod, and the other end with the treadle`s support. Put the dowel into the shaft, when you fixed the treadle.
  • Pump storage and care of Hoses
  • After irrigation is finished, roll up the hose properly in the field ,taking care not to drag it over sharp objects, and then carry it to the homestead. On no account should the hose be loosely folded and dragged over the ground from the field to the homestead, as this will decrease its service life. Store the pump and its fittings in a safe location. Pay particular attention to prevent damage to the hoses and rubber components. Seal the pump intake and discharge pipes to stop rodents gaining access to the flap valves in the valve box. When carrying or storing the pump, avoid denting the cylinders. If this happens the piston will not move easily within the cylinders and water will leak between the rubber piston seals and the cylinder wall, making the pump less effective, furthermore, try not to bend the piston rods.
  • Debris in the Valve Box
  • Mud or vegetation may be accidentally drawn into the Valve Box of the Pump through the Suction Pipe if no mesh strainer is used. To remove such debris, lay the Pump and remove ten nuts that fix the baseboard to the bottom of the Pump. Take great care not to lose any of the nuts or washers. With the nuts and washers off, remove the Baseboard and Rubber Gasket so give access to the Valve Box. Remove any debris and check the condition of the Rubber Flap Valves at the same time, which can be easily seen. After cleaning the Valve Box, fit on the Rubber Gasket, Baseboard and Washers, and retighten the ten nuts.
