  • Page 19 8. Models Proportional/constant pump driven by a current signal. Setting the switch on constant position, the pump has flow control (front panel knob may be set from 0% to 100% of pump nominal capacity). Flow control is electronically set and it operates on pump injections number. To avoid linearity problem do not set the knob of pump flow between 0% and 10%. Setting the switch on the proportional position, the pump capacity is set proportionally to analog current input signal; a signal change will be followed by a linear change of pump’s capacity. The current range is 0÷20 mA (0 dosing, 20 max dosing). The maximum pump capacity for maximum input signal is set by the % marked knob. The FIC pump can be controlled by any electronic device (such as pH-meter, redox-meter, etc) that has an analog current signal output. This signal must be applied to the bipolar cable provided with the pump, using the following connections: - Red wire : positive (+) - Black wire : negative (-) proportional constant stroke speed knob on/off button...

  • Page 21 8. Models Proportional/constant pump driven by a water meter digital signal. Setting the switch on constant position, the pump has flow control (front panel knob may be set from 0% to 100% of pump nominal capacity). Flow control is electronically set and it operates on pump injections number. To avoid linearity problem do not set the knob of pump flow between 0% and 10%. It is furthermore possible to divide the maximum magnet strokes per minute by 1, 10 and 100 using the switch on the front panel. Setting the switch on proportional position, for each external pulse corresponds one pump stroke. This pump can be driven by a CTFI or CWFI series water meters. This pump can also be driven by a digital signal coming from a “voltage free” contact. Driving signal is applied on the BNC plug on the left bottom of front cover. Dividing factor (N) value is obtained multiplying the value on the adjustment knob using the multiplying switch (x1, x10, x100). Capacity definition for “FPV” and “FAPV” pump Use the following formula to obtain minimum pump capacity: ppm x m ——————————————— = l/h 1000 x K l/h - minimum pump capacity required ppm - product amount to dose in p.p.m. (gr/m k - dosed product dilution factor (pure chemical k=1) - maximum capacity of system to be treated in m /h.

  • Page 23 8. Models FPVM Proportional/constant pump driven by a water meter digital signal. Setting the switch on constant position, the pump has flow control (front panel knob may be set from 0% to 100% of pump nominal capacity). Flow control is electronically set and it operates on pump injections number. To avoid linearity problem do not set the knob of pump flow between 0% and 10%. It is furthermore possible to divide the maximum magnet strokes per minute by 1 (÷1), 10 (÷ 10) and 100 (÷100) using the selector on the front panel. The electronic capacity adjustment sets the injection per minute. Setting the switch on the proportional position and the selector on “multiplier” (X1), the pump gives a stroke each 10 external pulses sent. Setting the selector on “divider” (÷1 or ÷ 10), the pump gives at maximum a stroke each external pulse sent and at minimum a stroke each 100 pulses sensed (knob n=10, switch ÷ 10). This pump can be driven by a CTFI or CWFI series water meters. This pump can also be driven by a digital signal coming from a voltage free contact. Driving signal is applied on the BNC plug on the left of the bottom pump cover. “FPVM” and “FAPVM” capacities are defined by the same formulas used for “FPV” and “FAPV”. proportional constant stroke speed knob on/off button selector “multiplier/divider” (1, 10, 100)
  • Page 24 8. Models Timered/constant dosing pump. Setting the switch on the constant position, the pump has flow control (front panel knob may be set from 0% to 100% of pump nominal capacity). Flow control is electronically set and it operates on pump injections number. To avoid linearity problem do not set the knob of pump flow between 0% and 10%. Setting the switch on timered , the pump starts working when an external pulse is provided. Working active time for each external pulse is set on the adjustment knob in the range between 0 and 60 seconds (different time are available upon demand). The capacity can be also changed adjusting the stroke per minute, operating the % marked knob, at the same time. The double parameter adjustment (strokes and time) allows the use of this pump in high capacity systems, where the pulses are not enough to drive a PV type pump. TE pump is provided of a coaxial cable (RG58) with BNC plug to connect the command signal. Use following formula to evaluate the knob adjustment: 3600 —————————— = sec. imp/h imp/h - water meter output pulse per hour sec - time in seconds to be set on time knob Maximum tag capacity can be decreased 10 or 100 times in the “F” and “FA” pumps using the 1/10/100 switch (where available). In that case the % marked knob will work on the maximum set capacity. timered time regulation knob on/off button stroke speed knob...
  • Page 25 8. Models FPDR Intermittent constant metering pump with adjustable pause and work times. Metering is set using three knobs on the front panel: - (%) knob (red coloured range) sets speed stroke - (10÷180 seconds) Pause knob sets time between one metering and the next - (10÷180 seconds) Work knob sets metering time Once powered the pump, it always starts its working cycle metering for the set time. The pump can be provided with a N.O. (1A / 230Vac) service contact: this contact is active while metering. If the level input is active while the service contact is active, pump stops and service contact gets back to N.O. Service contact is available through a bipolar cable out of the pump. Once refilled the tank or recovered the level input, the pump starts to dose for the remaining time missing to complete the set work time once stopped.
