BL7914 IPS MULTIRANGE PUMP
BL7914 offers four different ranges provid-
ing greater flexibility.
The flow rate is selectable from:
Knob pos. 2 0 to 2.5 lph (0 to 0.7 gph)
Knob pos. 5 0 to 5.8 lph (0 to 1.5 gph)
Knob pos.10 0 to 10.0 lph (0 to 2.6 gph)
Knob pos.15 0 to 13.3 lph (0 to 3.5 gph)
The above flow rates relate to 0.5 bar
(7.4 psi) pressure.
For charts with the typical flow rates against
pressure see page 11.
All selected ranges are adjustable from 0 to
100% of the pump's maximum capacity.
Other features include:
• Overheating is prevented by the thermo-
static circuit protection device.
• Isolated Power Supply provides the unit
with low voltage (12V) power from 220/
240V or 110/115 VAC for safety.
• Modular design with electrical and me-
chanical assemblies separated.
BL7913 IPS VARIABLE FLOW RATE PUMP
BL 7913 is a single range dosing pump, ideal
for use when the pumping requirement is
constant. The individual pump flow rates
can also be adjusted on the front panel from
0 to 100%.
Four models are available with different dos-
ing capacities:
BL7913/2 5.4 lph (1.4 gph) @ 0.5 bar (7.4 psi)
BL7913/5 7.6 lph (2.0 gph) @ 0.5 bar (7.4 psi)
BL7913/10 10.0 lph (2.6 gph) @ 0.5 bar (7.4 psi)
BL7913/15 13.3 lph (3.5 gph) @ 0.5 bar (7.4 psi)
