FMI Q2V - Manual

INSTRUCTIONS
MODELS Q2B, Q2V
The FMI Ratio:matic Duplex is similar in design to the standard FMI "Q" pump. Please review Q431- Instruction
and Parts Identification sheet for general information on both "Q" Models, and Instruction sheet V100 for the
variable-speed models "Q2V".
DESCRIPTION
The Ratio:matic Duplex pumps configure two Pump Head Modules (PHM's) on one Pump Drive Module. The
position of the PHM's is very important, see figs. 1 &: 2 for proper PHM positioning. There are two operating
modes for the Ratio:matic. In both modes, stroke rate is directly proportional to the flow.
IN-Q2-431- 08
2. Proportioning Flow: with suitable PHM
selection two separate fluids are precisely
proportioned. Ratios are varied by stroke
adjustment of respective Pump Head Modules
relative to each other, see fig. 2.
1. Doubling Flow: with two identical pump
heads twice the normal flow is achieved with
system pulsation's reduced as much as 50%,
see fig. 1.
