The RDS cylinder is available in 50mm, 60mm, 70mm and 80mm sizes. The RDS models are specially designed for boreholes deeper than 60 meters with a stroke length of 360mm (14"). The stainless steel tube is 60mm longer than the standard cylinders and operates with a double ring plunger. Rod supports and unique Jooste foot valves are fitted. The rust retainer is fitted on the last galvanised rod preventing rust or sand from settling in the cylinder.
