TE series self-priming centrifugal, drainage pumps are powered by compact Subaru-Robin diesel engines. They have carbon ceramic mechanical seals, aluminium pump housings, and, for increased abrasion resistance, have cast iron volutes and impellers. These materials ensure maximum durability for the pumping of clear and black water as found on building sites. All models are housed within a protective tubular steel, easy carry frame. Maximum suction lift is 8 metres, however 6 metres, or less, is recommended. They perform the same duties as petrol pumps, but enjoy the economies of diesel fuel without the bulk of the traditional engine design. Hose couplings, washers, clips and strainers are supplied with all pumps, but hoses are extra.
