Trade & Hire Flood Pump Kit | Stream SPK530 - 230V or 110V
Built for the job
Trade and hire flood pump kit for contractors, hire fleets and flood response
Two hoses, both voltage options, and a pump that clears a floor to 1 mm.
This FPS Engineered™ kit pairs the Stream SPK530 with 6m of 25mm reinforced suction and delivery hose, 10m of 25mm layflat, cam coupling and adapter and three stainless-steel clips. Run the short reinforced length on its own for a quick job, or couple the layflat on for 16m of reach.
We are the exclusive UK supplier of the SPK530, which appears on hire fleets and in flood response kits across the country. It steps up from our domestic puddle pumps on every count that matters on site: 170 litres per minute, 11 m of head, 5mm free passage, and a specially designed bottom plate that takes water down to around 1mm.
Part of our wider puddle pump, 110 V pump and flood defence ranges.
Why two different hoses
Because the first six metres and the last ten metres are completely different problems.
The hose leaving the pump has to survive the awkward part of the job: over a threshold, up a flight of steps, around a doorframe, through a hatch. That needs reinforced suction and delivery hose, which holds its shape and will not kink and starve the pump when it is bent. Six metres is enough to get out of almost any space.
Once you are outside, the problem changes. Now you want a light reach to get the water well clear of the building, and you want it to pack down small at the end of the day. That is layflat, which rolls flat, weighs a fraction as much and stores in a fraction of the space.
Supplying one type only means compromising at one end or the other. Most kits give you a single hose. This one gives you both, plus the joiner to couple them, so you use the right hose in the right place.
At a glance
- Pumps down to around 1mm: A purpose-designed bottom plate, so the floor comes back to damp rather than needing mopping.
- 170 litres per minute, 11 m head: 10,200 litres an hour, with enough head to lift out of a basement and still run a distance.
- Reinforced plus layflat: 6m that survives steps and doorways, 10m that gives reach and packs down small.
- Integral swing check valve: Built into the pump, so water in the hose cannot run back when you switch off. No separate valve to buy.
- Water-cooled for continuous duty: Rated to keep running at low water levels rather than cutting out when the water gets shallow.

Choose 230V for domestic and general-purpose mains, or 110V for site use through a transformer. Same kit, same hose, same fittings.
How the kit connects
The SPK530 has a 25mm discharge connector on top. The reinforced hose pushes over it and is secured with a clip. The discharge connector can be turned to run horizontally instead of vertically, which matters in a low crawl space or under a floor where there is no headroom for the hose to rise before it turns.
To extend, push the cam coupling and adapter into end of the suction and delivery hose and the layflat, securing each with a hose clip. That is what the three clips are for: one at the pump, two to join the cam attachments. Connect the cam attachments and fix togther by pushing down the locking handles.
There is no non-return valve in the kit because the pump has one built in. The integral swing check valve stops the water standing in the hose running back through the pump when you switch off, which on a lift out of a cellar is the difference between finishing the job and pumping the same water twice.
Two ways to run it
Estimated flow with the hose discharging freely. Uphill lift is measured from the water surface to the point where the hose discharges.
| Set-up | Uphill lift | Estimated flow | Per hour |
|---|---|---|---|
| 6 m reinforced only | 2 m | Approx. 115 L/min | Approx. 6,900 litres |
| 6 m reinforced only | 4 m | Approx. 100 L/min | Approx. 6,000 litres |
| 6 m reinforced only | 6 m | Approx. 85 L/min | Approx. 5,100 litres |
| Full 16 m run | 2 m | Approx. 85 L/min | Approx. 5,100 litres |
| Full 16 m run | 4 m | Approx. 75 L/min | Approx. 4,500 litres |
| Full 16 m run | 6 m | Approx. 63 L/min | Approx. 3,800 litres |
Estimated using the published SPK530 curve and Hazen-Williams friction for 25 mm bore, with the hose discharging freely. Only add the layflat when you need the reach. Every extra metre of hose costs flow, so the shortest run that gets the water somewhere safe is always the fastest. Work out a specific run with our pump performance calculator.
Manual control, and why that suits trade use
The SPK530 is manual. It has no float switch and will not stop on its own.
On an attended job that is what you want. A float switch would cut out with water still on the floor, and this pump exists to take the floor down to 1 mm. Manual means it keeps pumping until you decide it is finished. Read our blog on low level pumps
The trade-off is that it needs an operator. Switch off at the plug once the water is cleared, because running dry will damage the pump, and do not leave it as a standby pump in an empty sump. For unattended protection, our automatic sump and basement kits use level sensing instead.

Built for a hire fleet
Hire equipment lives a harder life than owned equipment. It gets loaded wet, stored badly, run by whoever is on site that day, and it has to come back working.
Wear-resistant parts and continuous duty. The water-cooled design lets the pump keep running at low water levels rather than tripping out, and the wearing components are specified for it. The thermal cut-out protects the motor when somebody inevitably lets it labour.
Layflat that stores. Ten metres of 25mm layflat rolls into almost nothing, which matters when a kit has to fit in a van alongside everything else and come out again undamaged.
What can I use it for?
- Flood response in homes, commercial units, cellars and basements
- Site drainage, excavations, trenches and hard standings
- Flat roofs, light wells, stairwells and lift pits
- Car parks, roadways and yards after heavy rain
- Behind flood barriers, clearing seepage as it collects
- Emptying water storage containers, tanks and unoccupied hot tubs once cooled
Water quality limits
Clean and lightly contaminated water, solids to 5 mm. Sand, silt and abrasive grit will wear any clean-water pump and can invalidate the warranty. Not for sewage, foul water or salt water. Where the water carries settled silt and fines that need stirring back into suspension, the EVAK Trenchman with its built-in agitator is the right pump.
Frequently asked questions
Why does the kit come with two different hoses?
Because they do different jobs. The 6m reinforced hose holds its shape over thresholds, up steps and around doorframes without kinking. The 10 m layflat is light and packs down small, which is what you want once you are outside and just need reach. The cam joiner couples them for a 16m run.
Do I need to use both hoses?
No, the 6m reinforced hose on its own gives you around 115 litres per minute at 2m of lift, against 85 with the full 16m coupled on. Only add the layflat when you actually need the distance.
Do I need a non-return valve?
No. The SPK530 has an integral swing check valve, so water in the discharge hose cannot run back through the pump when you switch off. That is one fitting fewer to buy, fit and lose.
Which voltage should I choose?
110V for construction sites, where power comes through a transformer. 230V for domestic properties, commercial buildings and general-purpose mains. If you work across both, most fleets carry 110V and use a transformer where needed.
How is it different from the Essential Home Flood kit?
Considerably more pump. The SPK530 moves 170 litres per minute against 70, lifts 11m against 6, passes 5mm solids against 3, clears to 1mm rather than 2, and is available in 110V. It also has a built-in check valve. The home kit is right for one property used occasionally; this one is built for repeat use across jobs.
Will it run continuously?
Yes. The water-cooled design is specified for continuous duty at low water levels, and the thermal cut-out protects the motor if it overheats. It still needs an operator, because it is manual and will not stop when the water is gone.
Can I add more layflat?
Yes, with another cam joiner and clips, but be realistic about the cost. At 25mm bore, friction is already taking more than half the pump's available head on the 16m run. Beyond about 20m you are losing more than you gain, so get the water somewhere safe as directly as you can.
