DV
Cooling Water, Ballast, Fire & G.S. Pump
The DV Series pumps are single stage, single suction vertical in-line centrifugal pump. The pump is radially split casing design and it is non self-priming. The pump shaft is well balanced by top ball bearing and bottom bearing bush. This ensures that the impeller is operating in optimal condition. The pump utilizes a flexible coupling, which allows the internal pump component to be removed without dismantling of the motor from the pump or the pump casing from the piping. The pump has a compact flange to flange distance allowing it to be installed in tight machinery space. The pump is noted for its robust construction, high efficiency and reliability. Self-priming of the pump can be achieved by incorporating external self-primer.
