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

This model delivers a maximum head of 50 metres, maximum suction of 3–4 metres, maximum pressure of 60 PSI and a maximum flow rate of 1330 litres per minute, which is listed as up to 80,000 litres per hour level. The pump also features a solid cast impellor and carbon ceramic seal, helping it handle hard-working conditions and making it suitable for sandy or pebbly water.  

Power comes from a DEK F700 New Series 668cc 18hp air-cooled diesel engine with single cylinder direct injection and electric start, giving you diesel efficiency with straightforward starting on site. A 5.5 litre fuel tank and listed 88dB noise level at 6 metres round out the package, making it a solid choice for larger transfer jobs where petrol is not ideal.  

As with other serviceable equipment we sell, we can support this pump with in-house servicing and repairs in Hamilton, and we carry backup and replacement parts. This unit is shipped on a pallet and needs to go to an urban business address, with home delivery available by quote. It is backed by a 12 month domestic warranty and 6 month commercial warranty.
