The DC and DCT are a range of heavy duty high head pumps manufactured by Pentax, designed for the drainage of both clean and dirty water in industrial and domestic settings. Engineered from solid cast-iron pump body and impeller, the Pentax DC and DCT pumps benefit from a double oil bathed mechanical seal housed within a lubricated chamber which offers positive seal lubrication which extends the pump life and offers reliability time and time again. They have a max immersion of 20 metres and the single phase versions are supplied with an external capacitor.
