Davey Firefighter pumps are available in petrol or diesel and single or double stage versions with three or four-way discharges. Petrol driven models are powered by an industry leading Honda petrol engines, while diesel models benefit from a Yanmar diesel engine.

Patented clamped impeller designs enable a longer impeller life, improved performance and easier disassembly in the case of blockage. Pump casings, diffusers and impellers are manufactured from quality corrosion resistant marine grade aluminium for longevity.

The pumps boast patented floating impeller neckrings on the front and back. The front neckring helps improve pumping efficiency, while the back neckring helps extend seal life and dramatically reduces engine wear.
Self-priming from 6 m for the single stage model and 7 m for the twin stage model allows for more versatile installation options.

Further, the pumps also feature low-oil protection on all models. This feature prevents the engine from starting or running if the oil level is inadequate, thus protecting the engine. Electric start models have an electric starter, which requires batteries and leads. Models fitted with recoil starters ensure a choice of starting methods, even if the battery is flat or removed.

How do I choose my Davey Firefighter?
The first step in benefiting from the Davey Firefighter is choosing the best pump for the application at hand.

First, the user needs to choose between single stage and twin stage models. The two models share many of the same great features but the twin model’s double impeller design provides extra strong pressure for longer and higher pumping applications such as uphill applications. The single stage provides a versatility of high flow rates. The single stage models can be identified by their yellow pump casing, while the twin stage has a red pump casing.

Secondly, choose between petrol and diesel. Petrol is recommended for intermittent use, while if the pump is going to be used for prolonged periods, the diesel models are better suited. The range of petrol engines starts with the Honda GX160 (163CC). The diesel Yanmar engines start at 320CC up to the top of the range at 430CC.

Thirdly, decide between pull and electric start. Electric start models simply start easier, but pull starters power-up without the use of batteries.

Fourthly, use an estimate of the volumes of water that will have to be pumped to decide on an engine size. The larger the volume of water the bigger the required engine capacity. This will also help you dictate what size tank to choose.
