Low-Pressure RO Boost Pump – MARCH Mag-Drive Submersible Series

Low pressure boost pumps are used to maintain positive pressure at the inlet of the high pressure pump. Failure to maintain positive pressure at the inlet of a high pressure plunger pump can cause severe damage to the plungers due to cavitation. At Boundless Outfitters, we have curated a collection of low pressure pumps based on common feed flow rates. This MARCH Pump 893-13 is ideal for RO desalinator systems with maximum 0.5 GPM feed pumps. We recommend installing this RO boost pump at least one foot below the waterline to avoid inlet cavitation. This liquid-cooled submersible pump is ideal for damp bilges.

March Pump’s industrial pumps are American seal-less centrifugal magnetic drive pumps ideal for reverse osmosis (RO) feed pump applications. The standard wet end (the materials that come into contact with the solution) is composed of Noryl, Polypropylene, Buna N, Ceramic, and Ceramic Magnet.
