Abstract

A positive displacement multi-cylinder pump, or "radial pump" which cylinders are set in a radial configuration around a central crankcase. The radial pump has been especially designed for the seawater desalination using reverse osmosis (RO) membrane equipment. The pump acts as 1) a high pressure high flow positive displacement pump, 2) a brine energy recovery device, 3) a variable recovery system, and 4) a brine re-circulation system.
