The pump may be started by applying air pressure to the air valve fitted. In the event of failure to start
the manual overrides fitted to the air valve below the air inlet should be pushed so that the spool is
repositioned, repeat as necessary.
Note the pump will not operate if the head of fluid resistance on the fluid delivery side of the pumping
is equal to, or exceeds air pressure. If a valve is fitted to the suction or delivery side of the pump, this
must be in the open position.
If a valve is fitted adjacent to the pump on the delivery side of the fluid pipe-work, this may be used to
control flow and when necessary, closed to stop flow without damage to the pump. Alternatively, the
pump may be controlled by opening or closing, or varying the air supply, using the valve fitted.
The pump is normally fitted with a 5 port air valve on pumps with 7” and 10” diameter diaphragms,
and with special design, FPL valves on larger size pumps. Capacities and flow rates shown on our
literature and data sheets are based on the use of these valves. Capacities and flow rates may vary if
other types of 5 port valves are fitted. Flotronic pumps reserve the right to supply pumps fitted with
alternative types of valve without notice.
