This Stainless Steel Cylinder is manufactured with an SS 304 grade body, offering excellent resistance to corrosion, rust, and chemical attack from borewell water compared to conventional cast iron cylinders. It is fitted with SS 316 valve components, a higher corrosion-resistant stainless steel grade specifically chosen for the valve assembly to withstand continuous water contact and repeated mechanical stroke action, paired with nitrile rubber components for reliable sealing on each pump stroke. The cylinder delivers a discharge capacity of 15 liters per 40 strokes per minute, providing efficient and consistent water output for daily use in community and household hand pump installations. This cylinder is also available in a modified configuration for India Mark III pumps, with an open top cap designed to suit a 65mm N.B. G.I. or PVC riser pipe, allowing convenient servicing and replacement of nitrile rubber components without full riser pipe removal. Designed as a dual-purpose cylinder, it is suitable for lifting water through both submersible pumps and hand pumps, making it a long-lasting, low-maintenance choice for installations where corrosion resistance and hygiene are a priority over standard cast iron cylinders.
