The filtration system includes a tank (10) and a pump (P) for pumping filtrate form the tank (10) into a discharge manifold (40). The pump (P) includes a suction inlet port (94), an impeller (53) and a discharge head (H). A suction connection (32) is provided in the side wall of the tank (10). The unit has a fixed discharge housing (46) including an annular enclosure (90). To install the pump (P), the inlet suction port (94) and impeller (53) are passed horizontally through the annular enclosure (90) for sealing connection with the tank receptor ring (30). The discharge head (H) is mated with the annular enclosure (90) whereby filtrate may be pumped from the tank (10) through the discharge head (H) to the manifold (40). The remove the pump (P), the installation procedure is reversed, beginning by withdrawing the discharge head. Alternatively, the pump can be pre-mounted in a holder (68) with the discharge head prealigned with the annular enclosure, with the above sealing connection not required. |
