The tank elevation and lateral distance from the metering pump are critical in assuring adequate suction pressure. Level controls and gauges. Job site conditions determine the necessity for remote level gauges and alarms. In all cases, however, a visual calibrated and valved gauge glass should be provided. The basket is placed inside the chemical storage tank.
Some chemicals deteriorate upon exposure to the atmosphere.
Coordinating the floating seal, mixer and dissolving basket in one tank may present a challenge. Suction piping sizing considerations. The suction piping is critical, both with regard to materials of construction and sizing. Obviously, materials must be compatible with the chemical used, and pipe sizing must be adequate for free-flow to the pump suction intake. Distance is also a critical factor, as metering pumps have an entirely different flow formula from other pumps and require much larger suction piping.
