Your expectation is our standard


The RDV6 pump is a type VS6 vertical multistage can type pump that is used in situations where Net Positive Suction Head Available (NPSHA) is limited. The pumps are designed to the latest edition of API 610 and API 682 standards. The RPG VS6 vertical shaft pumps are engineered with a barrel (suction can). An extensive range of hydraulics gives a comprehensive range of heads and flows to match your process. Varied material options are also available to suit specific fluid requirements.
