The p u m p s are required to p u m p a m i x t u r e of oil, sea water, H20 and particles, at a pressure of 9 bar. Robust and weatherproof, the p u m p s are designed to w i t h s t a n d even the most arduous North Sea conditions, including waves, sea spray a n d temperatures ranging from -7°C to 40°C. The pumps incorporate Mono's Flexishaft system, which provides a single c o m p o n e n t link between the rotary m o t i o n of t h e d r i v e s h a f t a n d t h e eccentric m o t i o n of the helical rotor.
