SEFEX Presurized Treadle Pump is a foot operated two cylinder pump and uses Treadles to engage both the operator's legs and full body weight. It can be used to lift water from bore wells, canals, ponds, streams etc. and it is designed to irrigate small area of crops. Water can be delivered overhead Tank upto 16 Mtrs height from ground level. The whole body and other metal parts of the pumps are hot dip galvanized, to minimize the effect of rusting on the metal parts as these parts are always in contact with water. It makes this pump more durable. 

 

The pump is human powered to eliminate the fuel and oil costs associated with motorized pumps and reduces the crop damage and income losses associated with mechanical breakdowns and interruption of the fuel supply. The treadle pump is simple and efficient. If the pump is properly adjusted and maintained, the pump can be operated several hours a day without tiring the operator. The leg muscles, which are the most powerful part of human body, provide the power to drive the pump. Moreover, the pump is operated in a natural way, as walking. 

 

The treadle pump can raise water by suction and by pressure, just like a motorized centrifugal pump. It can also pump water through a distribution pipe. The pump can be used by one adult only. The total vertical distance that water can be pumped is limited by the total weight of the pump operator. One adult weighing 50 Kg. can pump water up to 8m to 16m vertically. 

 

PRODUCT GENERAL DATA

CONSTRUCTION OF PUMP 

Essentially the pump has following parts

  • Pump body having two parallel cylinder and valve box, duly hot dipped galvanized.
  • Two-piston assembly fitted with Cam & Chain arrangement, duly hot dipped galvanized Fig A
  • Two-piston assebly duly galvanized with CI Pulley & Steel rope arrangement Fig B.
  • Two mild steel Treadles rectangular hollow pipes, duly hot dipped galvanized
  • Rubber Valves & Cups (Buckets) v) T-Handle having hollowed pipe, duly hot dipped galvanized. 

 

PUMP BODY 

The cylinders of the Treadle pump are made from mild steel 2mm sheet, which are rolled around and subsequently arc welded, while the Mandrel remains inside the cylinder. This method produces cylinders, perfectly round & smother. The first part of the pump body is the valve plate, which is the top of the valve box to which the Cylinders are welded. The cylinders are placed at the centre on the valve box. This is done to provide room inside the cylinders for seating of the Inlet/Outlet valves. The whole body and other metal parts are hot dip galvanized to minimize the effect of rusting on the metal parts as these parts are always in contact with water. 

 

PISTONS 

The pistons of the Treadle pump consist of two Rubber cups, which are held together by a z clamp at the end of the piston rod. A steel washer is placed between the two Rubber cups. The upper cup faces towards the top of the cylinder. It seals the Piston when the pump is acting on the suction stroke, while the Piston is moving upward. The lower cup faces towards the bottom of the cylinder, it seals the piston when the pump is acting on the Pressure stroke, while the piston is moving downward. Since the Rubber cups are flexible, they expand against the Cylinder as a result of atmospheric pressure (for the upper cup), and the pressure of the water inside the cylinder (for the lower cup), thereby sealing the piston.

 

VALVES

Four rubber valves are used in the Treadle pump, (one Inlet and one Outlet valve in each cylinder) all the valves are simple Check valves which open/close in response to the water pressure acting upon them. The Outlet valve opens away from the cylinder and lets water out of the cylinder when the piston is moving down ward. The Inlet valve opens in to the cylinder and lets water in to the cylinder when the piston moves upward. The two Inlet valves draw water from the Inlet chamber of the valve box that connects it with the Intake pipe. The two Outlet valves discharge water into the outlet chamber, connected to the outlet pipe of the pump.

 

TREADLES 

Treadles are made of rectangle hollow pipe, with broad chequered plates, duly hot dipped galvanized to provide firm grip to user's foot.

 

CAM & CHAIN ARRANGEMENT (FIG. A)

A cam system has been introduced for up and down motion of Treadles. Cam is fabricated of mild steel plate/pipe with Plastic bush for free and friction less movement of Treadles. Chains are used to link treadles with pistons. Axle shaft made up of Mild Steel round is used with Plastic Bush for free movement of Cam & Chain arrangement.

 

5a. PULLEY & STEEL ROPE ARRANGEMENT (FIG.B)

A pulley & steel rope system has been introduced for Up and down motion of Treadles. Pulley is made up of Cast Iron round for free and friction less movement of Treadles. Steel rope is used to link Piston. Treadles & Pulley fitted on Axle shaft of the fixed block.

 

T-HANDLE

T-Handle is made up of mild steel hollow pipe Round/Square duly of dipped galvanized.

 

FOOT VALVE 

At several occasion, users find problems of "priming" in Treadle pumps during start up which consume great deal of their energy. This problem can be eliminated by using a foot valve at the bottom of Suction Hose.

 

Operation Features :

  • The Treadle pump follows the basic lifting principle of the hand pump. It consists of two barrels, pistons and treadles and is operated by one person, who manipulates his/her body weight on the Treadles.
  • The discharge of water ranges between 1400 - 1600 liters Fig. A. and more than 1600 liters Fig. B. per hour.
  • The pump is easy to install, requires little maintenance and can easily be repaired by the user.
  • Minimum operating costs, as it requires no fuel or electricity.
  • The  SEFEX Treadle Pump effectively irrigates land holdings.
  • SEFEX Treadle Pump is best suited to water levels less than 7m below the ground level & has a total pumping head of 15m. Its use is recommended to lift water from ground or surface water-rivers, ponds, streams, canals, wells etc.
  • SEFEX Treadle Pump is one of the cheapest irrigation systems currently available.
