• Bearing bushes for the pivot assemblies are made from injection moulded 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 centralisers on riser pipes prevent external wear.
• Standard cylinder components are comprised of injection moulded 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.
• Two options for pedestal designs are available:
  1. Pedestal for concrete stand
  2. Pedestal of India Mark II design with either 3 legs mounting or flange mounting arrangement.
• U-Seal, bobbins and ‘O’ Rings are of Nitrile Rubber and Plunger Rod of Stainless Steel.
• 10 mm dia. x 3 Meters long 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.
• Each rod is provided with a Rubber Centraliser 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.
• A new innovation of BIAC’s R&D Department is 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.
