2. Location
Choose a location for the pump which is clean, dry, close to an electrical outlet, and allows convenient access
to stroke length control, frequency control, and tubing connections. Avoid areas where ambient temperature
exceeds 40 °C or falls below 0 °C, or where the pump or tubing would be exposed to direct sunlight. Flooded
suction (mounting the pump below the level of liquid in the supply tank) is strongly recommended, especially
when pumping liquids that readily generate gas bubbles. Sodium hypochlorite and hydrogen peroxide are
common examples of such liquids. (See Figure 1.)
If flooded suction mounting is not possible, a shelf adjacent to (but not directly above) the supply tank often
works well. (See Figure 2.) The supply tank or cover can also be used if it has provisions for mounting a pump.
(See Figure 3.) In any care, the total suction lift should not exceed 1.0 m.
