With years of experience in handpumps, Balaji Industrial & Agricultural Castings now brings you the Balaji Direct Action Pump (TARA) under the guidance of UNICEF.

Tara has all VLOM (Village Level Operation & Maintenance) features, suitable for drawing water from low to medium lifts (up to 15 meters). Having proper bore-sealing and without the need of priming (as required in the case of suction pumps), this pump eliminates the possibility of contamination of tubewell water and delivers the ground water that is stored in underground geological formations, which has been found to be biologically safe for human consumption. TARA is suitable for more aggressive soil and water as the below ground components are made of µPVC, thermo-plastic mouldings and stainless steel. This Direct Action Hand Pump is a fine example of excellent workmanship and high standards of quality. That is the hallmark of BIAC.

Salient Features

• The Tara pump conforms to the VLOM concept.
• T-Bar handles at the top of the pump rod for easy operation.
• Cylinder installation is recommended up to a depth of 15 meters below ground level. The diameter of the cylinder is 50 mm. with a maximum stroke of 410 mm. yielding approximately 35 liters per minute.
• High discharge. Discharge in both upward and downward strokes.
• The above ground mechanism consists of a sturdy mild steel hot dipped galvanised fabricated pump head, handle and standing plate.
• The handle bar is jacketed with a stainless steel sleeve for protection against wear and tear and for smooth operation.
• Below ground mechanism is constructed from corrosion resistant components.
  
  
  1. Pump rod and riser pipe are made of HDPE.

Walimi Deep Well Hand Pump manufacturing as per SKAT / HTN Specification

Walimi Hand Pump is available with two different cylinder sizes, suitable for lifting water from depths of 5 m. to 40m.

Stroke length of the pump is 160 +/ - 5.0 mm.

Cylinder of 3" is recommended for depths between 5 to 25 mts. and the discharge is 35 ltrs per Minute of 40 continuous strokes.

Cylinder of 2" is recommended for depths between 20 to 40 Mts. and the discharge is 15 ltrs. per Minute of 40 continuous strokes.

The Walimi Hand pump is suitable for boreholes with casing sizes of nominal bore 100 mm (4"), 125 mm (5") and 150 mm. (6") internal diameter. For exact positioning of the rising main, the corresponding centralizes need to be placed at every pipe joint and one at the cylinder.

If the Walimi Handpump is to be used in dug wells, no suction pipe and centralizes are required. To avoid swinging of the rising main during operation, precautions to be taken for locating the riser pipes inside the well and the "Anti-swing pipe" has to be fixed.
