Tara Pump DetailsTara Pump Details[Home] [Up] [Table of Contents] [Mark II/III/VLOM 50] [Extra Deepwell] [Shallowell Handpump] [Malawi Treadle Pump] [Afridev handpump] [Metal Treadle Pump] [Centrifugal Pumps] [General Info] [Info Request Form] [Water Supply Options] [Guest Book] [Working of a Handpump] [Downloads] [SS/PVC components]TARA Direct Action Handpump Construction DetailsTara Handpump is a revolutionary product which gives water in both the upward as well as the downward stroke of the handle. Since all the underground parts are made of non-corrosive material like PVC and Stainless Steel., the pump is extremely durable over the years.This is also aThis is also a VLOM ( Village Level Operation & Maintainence ) Pump like India Mark IIIThese handpumps are designed for lifting water from bore wells with static water level not exceeding 15 m. They are more cost effective than the Deep well handpumps for medium lifts and are safer from bacteriological contamination and corrosion problems.The term ‘ Direct Action ‘ for a handpump refers to a vertical pumping action using a ‘ T ‘ bar handle connected to a buoyant PVC pump rod. The load is transmitted directly from the user to the pump rod and piston during operation. The buoyant pump rod, of a relatively large diameter,displaces water in both the upward and downward stroke and the buoyancy of the pump rod makes pumping operation easy. The above mechanism eliminates the complications of a lever action handpump such as bearings, axle etc. The direct action handpump is designed for eseyinstallation, construction and maintenance .Construction Details ( See Diagram at the bottom of this page )1. Pump head assembly2. Pump rod assembly3. Rising main4. Cylinder assembly5. Tube well assemblyPump Head AssemblyThe above ground structure consists of pump body and a T-bar handle for direct applications to operate the plunger. The height of the pump body from the platform and the length of handle is designed to suit the stature of different users with comfortable movement of handle for a strokelength of 300 - 400 mm at various positions. Manufactured from high quality steel, this assembly is given a protective zinc coating by hot dip galvanising for effective corrosion resistance.The pump is fabricated from 65 mm and 50 mm NB standard mild steel water pipe and a base flange. The two flanges compress a rubber grommet around the upper well casing as they are tightened, and this forms a sanitary seal between the pump-stand and the casing.The T-bar handle assembly is fabricated from 20 mm NB mild steel pipe by welding the cross-piece to the shaft and the handle nut to the bottom. The assembly is then hot-dip galvanised. It has an overall length of 760 mm, after allowing for the length of the bush and permits a randomstroke length of up to 400 mm. The guide bush is made from HDPE material.The pump rod assembly transmits the mechanical force applied by the user from the pump handle to the piston assembly. In the case of the Tara Direct Action handpumps, the pump rod has another important function : it divides the operating force between the up and down strokes,making it easier for the user.The pump rod assembly consists of top and bottom connectors permanently joined. The top connector joins the uppermost PVC pipe segment to the handle. The connector is a threaded bolt inserted into a PVC bush, machined to fit into the end of the pump rod.The bottom connector joins the piston assembly to the lower end of the pump rod. It consists of a stainless steel spindle .The 3m-long PVC pump rod segments are PVC pipes solvent cemented together using internal connectors consisting of PVC injection moulded threaded adapters. This assembly provides the linkage between the pump handle and the piston in the cylinder. With their light weight and highdisplacement capacity these rods help in reducing the efforts required for the upward stroke due to buoyancy.Rising Main/Cylinder AssemblyThe rising main is connected at the bottom, to the cylinder assembly, and carries water from the cylinder to the pump head. These are 3 m of PVC pipes joined together with a threaded coupler.The cylinder assembly contains the piston rod, piston, foot valve, etc. to provide the necessary pumping action. This mechanism lifts the water upward through the rising main at each stroke. The cylinder body is basically a PVC pipe with a foot valve retainer at the bottom to support thefoot valve. The foot valve receiver is a tapered section at the bottom of the cylinder, which is injection moulded. The cup washer made from high quality nitrile rubber provides easier pump operation. Other components are made from stainless steel, themoplastic mouldings and nitrilerubber. A S.S. grapple is provided with the piston assembly to facilitate the extraction of the foot valve for repair work without removing the riser main.The piston assembly bears the load of the column of water on the upward stroke of the pumping cycle. The rubber flap valve closes on the upstroke to seal the piston parts and opens on the downward stroke to let water pass through to repeat the cycle.The foot valve assembly bears the weight of the column of water and prevents it from leaking while the piston is moving down. The foot valve then opens to allow water into the cylinder on the upward stroke. The assembly consists of a moulded body of high density polyethylene withtriangular apertures covered by a flap valve. A bolt moulded into the valve body connects to the double T-bar guide and an O-ring makes a static seal against the walls of a tapered receiver at the lower end of the cylinder.The angle of seating in the receiver is provided to prevent the O-ring from rolling out when the foot valve is extracted for repair.Tube Well AssemblyIt consists of upper well casing, lower well casing and well screen assembly. The lower casing is provided to place the well screen at the correct underground aquifer. The upper end of the lower casing is cemented to the lower end of the upper casing through the reducing socket. The lowerend is attached to the screen. The well screen, made out of PVC ribbed pipe, is specially designed to provided increased open area and less sand penetration.Retrieving Rod AssemblyThis rod assembly helps in extracting the foot valve assembly from cylinder for maintenance. This rod is manufactured out of 12 mm M.S. Rod and is electroplated.http://www.skipumps.com/tara_details.htm (1 of 3) [1/13/2005 12:46:11 PM]
