We are offering afridev hand pump. Introduction
“aov”
afridev hand pump
application data
minimum bore size .. 100 mm.
Internal dia. Of cylinder ... 50 mm
stroke length ... 225±3 mm.
Average discharge per stroke ... 17 liters per minute of 40 strokes.
Operating depth (approx.) ... Up to 80 meters
salient features data
• bearing bushes for the pivot assemblies are made from injection molded special grade plastic.
• variable handle settings suit changes in static water levels.
• 225 mm stroke length of the handle provides a water discharge of 17 litres per minute per 40 strokes with an installation depth range between 15 m to 45 m below ground water.
• easy to install, can be accomplished by village women mechanics.
• cone plate and rubber cone for improved attachment of upvc riser pipe to pump body.
• extra long spigot ends in riser pipe to ensure high joint strength, leak proof pipe joints, and verticality of the pipe string. Rubber centralizers on riser pipes prevent external wear.
• standard cylinder components are comprised of injection molded interchangeable plunger and foot valve assemblies, made from modern engineering plastics.
• the afridev pump’s cylinder is also suited to use cast gun metal monolithic plunger and foot valve assemblies of the universal cylinder.
• alternative stainless steel lined cylinder is available for aggressive water conditions.
• quick release eye & hook ‘tool-less’ ends on connecting rods with rubber centralisers, are standard supply. These facilitate maintenance and protect the riser pipe against internal wear.
• the vlom (village level operation and maintenance) design has been developed for easy handling of maintenance problems without the need of special skills.
• non-corrosive underground components are capable of handling corrosive water and therefore will last longer.
• lightweight µpvc riser pipes; easy installation & inexpensive.
• adjustable handle to suit varying installation depths.
• three options for pedestal designs are available:
a. square flanged.
B. three legged.
C. skat -4, pedestaly with anchor assembly.
• cup seal, u-seal, bobbins and ‘o’ rings are of nitrile rubber and plunger rod of stainless steel.
• mild steel hot-dip galvanized rod / ss with forged eye and hook connectors welded at both ends. this provides easy rod connections without use of any tool. & also connecting rod with welded coupling.
• each rod is provided with a rubber centralizer to avoid contact with µpvc riser pipe.
• fulcrum & rod hanger pins are supported on special grade plastic bush bearings which are very easy to replace at village level.
• µpvc cylinder 50 mm id with gun metal plunger assembly / inter changeable plunger and foot valve made with special grade plastic material.
• µpvc pipe 63mm od x 47 mm wall x 3 meters long with socket-spigot cemented joint.
• each pipe is provided with a rubber centraliser to avoid contact with casing pipe.
• the fgrp connecting rods (glass fibre reinforced plastic), which provide the same advantages of mils steel & stainless steel, yet are light weight and long lasting.
