Leading Supplier and Manufacturer of Hand Pump such as Malda Hand Pumps, Afridev Deep Well Hand Pumps, Extra Deep Well Mark ll and India Mark II Deep Well Hand Pumps from Bengaluru.
Malda Hand Pumps
The design of malda hand pump is based on a buoyant pump rod that is directly articulated by the user, discharging water in both up and down strokes. It suitable for lifting water from depths of 1 to 15 meters. This kind of pump eliminates every possibility of contamination with proper bore sealing, without need of any priming (as required in the case of suction pumps). Malda hand pump creates required force to draw ground water stored in geological formation below the ground, which has been found to be biologically safe for human consumption. Malda has been specially designed to be used in boreholes and in drug wells. The pump conforms to the quality standards of skat, switzerland. These pumps are easy to install and maintain. Most of the repair and job can done with simple hand tools only. Construction all the 'below ground' components, riser main pipes & pump rods are made of hdpe. The pump stand assembly and pedestal assembly are hot dip galvanized conforming to iso 1461 for protection against corrosion. The coating thickness pedestal assembly and pump stand is 70 to 80 microns.
