The field-proven Shurflo 5059-3611-D011 pump delivers 14.4 litres per minute at 2.75 bar with current draw of 14 amps.

This pump is designed with a Santoprene® diaphragm for chemical resistance and maximum life, as
well as Viton® valves for maximum chemical resistance. Also included is a builtin
bypass, set at 90 PSI [5.86 bar], which protects the pump in the
event of dead-heading. The pump is available in the same footprint as other
Shurflo pumps, allowing users to upgrade to a higher performance on existing
installations.
