The DEK 100-80 Cast High Pressure Diesel Pump is built for serious pumping jobs where you need strong flow, solid pressure and diesel reliability. With a cast iron pump, 100mm (4”) inlet and 80mm (3”) outlet, this unit is designed to move large volumes of water efficiently while still delivering the pressure needed for tougher transfer work. It is a practical option for New Zealand farms, irrigation setups, rural properties and contractors needing dependable high-volume pumping performance. 

This model offers a maximum head of 50 metres, maximum suction of 3–4 metres, maximum pressure of 60 PSI and a maximum flow of 1330 litres per minute, with output listed as up to 80,000 litres per hour level. The pump is fitted with a solid cast impellor and carbon ceramic seal, and the product page notes it is suitable for sandy / pebbly water, making it a good fit for harder-working conditions. 

Power comes from a DEK F420 New Series 420cc 11hp air-cooled diesel engine with single cylinder direct injection and both electric and recoil start, giving you a straightforward and reliable diesel setup on site. A 5.5 litre fuel tank, 88dB noise level at 6 metres, 68kg weight and compact overall dimensions make it a strong option for users wanting diesel pumping power without stepping up to a much larger machine.

The listing notes this unit is shipped on a pallet, must go to an urban business address, and home delivery is available by quote.
