*NOTE:
“Start up”
performances are available when the pump starts the operations and are constant only if duties are
not continuous (working for time periods not over 20/30 min and with at least 15 min rest).
2.5 – PERFORMANCE CURVES
3.0 – COMMISSIONING
CTRL2-7L series is provided with a
quick mounting support bracket:
a.
- Install the pump in a dry place, firmly to avoid vibrations, and well away from sources of heat and, in any
case, at environmental temperatures not exceeding 40°C. The minimum operating temperature depends on
the liquid to be pumped, bearing in mind that it must always remain in a liquid state.
b. -
Fix the wall support brackets as shown in (fig.3).

Performance curves (fig.2) are obtained testing the pump with water at room temperature and nominal suction height.
The above diagrams indicate max metering pump flow variation in relation to the working pressure in the plant; the
diagrams also include i.v.p. flow loss (injection valve pressure about 0,3÷0,4 bar).
REMINDER: ratings vary with a tolerance of ±5% CTRL2 - 7L / ±10% CTRL2 - 5L which must be taken into account when choosing
the pump typ: above diagrams show the performance and some of the curves have slight variation from nominal rating.
NOTE
when programming pump operations keep in mind that flow variation are related to the system pressure
variation; refer always to pump curves. Also consider that unexpected flow variations may occur for reasons not related
to pump functioning (viscosity, specific weight, sedimentation, etc).
