The TD series are automatic priming, diaphragm pumps powered by Honda 4 stroke petrol engines (with oil alert). With diaphragm pumps, priming is unnecessary and indefinite dry running is permissible. They can handle site water containing sand, silt and suspended large solids. All models have a lightweight pump end and engine, housed within a protective tubular steel, easy carry frame, but a two wheeled trolley is available as an optional extra. For vibration control rubber engine mounts are fitted. A quick release cam coupling kit, with heavy duty hose clamps, is an optional extra for operator convenience. This popular series of pumps are widely used by contractors, utilities and regularly found on hire fleets.
