SERVICE PUMPS
There are four horizontal, two-stage, centrifugal service pumps used to pump raw water from the water source,
pump water from the settling tank to the UF module for the first filtration, pump water as a backwash of the UF
membrane cartridges in the UF module, and distribute product water from the product tank.
The pumps are non-self-priming type. The service pumps connect to the control module with electrical cables.
The service pumps are interchangeable but the couplings on the suction and discharge ports have different
configurations for the function to be performed. The service pumps are mounted on an upper/lower module for
transportation and storage. Maximum permissible operating pressure is 145.04 psi (10 bar). See Figure 14 and
Figure 15.
