The filtration system includes a tank and a pump for suctioning clean filtrate from the tank and pumping filtrate into a discharge manifold. The pump includes a suction inlet port, an impeller and a discharge head. A suction connection to the filtrate is provided in the side wall of the tank and a fixed discharge housing includes an annular enclosure which cooperates, when the pump is installed, with the pump discharge head to connect the pump discharge to the manifold. To install the pump, the inlet suction port and impeller are passed horizontally through the annular enclosure for sealing connection with the tank receptor ring. The discharge head mates with the annular enclosure whereby filtrate may be pumped from the tank through the discharge head to the manifold. To remove the pump, the pump is displaced in the opposite horizontal direction by withdrawing the head from the annular housing and the impeller and suction inlet port through the annular housing. Alternatively, the pump can be pre-mounted in a holder or container, with the discharge head prealigned with the annular enclosure, where the inlet suction port does not require sealing connection with a receptor ring. |
