Treadle Pump

Ajay Pressurized 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 12 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 fuel and oil costs associated with motorized pumps and reduces the crop damage and income losses associated with mechanical breakdown s and interruption of the fuel supply. The treadle pump is simple and efficient. If the pimp 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 the water can be pumped is limiter by the total weight of the pump operator.

INTRODUCTION

One adult weighing 50Kg. can pump water up to 8m to 12m vertically.

Essentially the pump has following parts

1. Pump body having two parallel cylinder and valve box, duly hot dipped galvanized.

2. Two-piston assembly fitted with Cam & Chain arrangement, duly hot dipped galvanized Fig A.

3. Tow mild steel Treadles rectangular hollow pipes, duly hot dipped galvanized

4. Rubber Valves & Cups (Buckets)

5. T-Handle having hollowed pipe, duly hot dipped galvanized.

CONSTRUCTION OF PUMP

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 & smoother. 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.

PRODUCT GENERAL DATA

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.

PISTONS

VALVESFour 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 and lets water in to the cylinder when the

piston moves upward. The two Inlet valves draw water from the Intel 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.

1) CAM & CHAIN ARRANGEMENT

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

Following two types of models are available

(A) Galvanized steel Treadle Pump with Cam & Chain arrangement

1. Suction Lift : 7mtrs maximum

2. Delivery Head : Upto 16 mtrs

3. Discharge : 1400-1600 liters/hour

4. Irrigable Area : Upto 2 acres of land

Cam & Chain arrangement

T-HANDLE

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

galvanized.

FOOT VALVEAt 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.

PEDALING TO PROSPERITY• For millions of farmers the Treadle pump can bring a sea change to their live.

• It gives them ownership of water-cucial for a successful harvest.

• It is more efficient, more affordable and most appropriate to their needs.

• It provides an assured access to water, freeing farmers from the vagaries of nature or erratic electric and diesel supply.

made up of Mild Steel round is used with Plastic Bush for free movement of Cam &

Chain arrangement.

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 1500 - 1600 liters per hour.

• The pumps is easy to install, requireslittle maintenance and can easily be

repaired by the user.

• Minimum operating costs, as it requires no fuel or electricity.

• The AJAY Treadle Pump effectively irrigates land holdings.

• AJAY Treadle Pump is best suited to water levels less than 7m below the

ground level & has a toal pumping head of 15m. its use is recommended to lift

water from ground or surface water- rivers, ponds, streams, canals, wells etc.

• AJAY Treadle Pump is one of the cheapest irrigation system currently

available.

• Can push water uphill as well as simply pulling it from the source.

• Can be used on steep sloping land where the water source may be at the

bottom.

• Ownership of water-crucial for a successful harvest.

• Greater efficiency than traditional methods.

• More affordable than diesel and electricity-driven pump sets.

• Assured access to water without being subjected to the vagaries of nature

and erratic electricity and diesel supply.

• Flexibility to grow a variety of crops. which have different irrigation needs.

• Easy operation in many cases the pump is owned and operated independently

by women.

• Easy self-maintenance.

• Self-reliance a tool, which give farmers a just return on their labour.
