For site dewatering tasks where high flow rate matters but available space is restricted, a deep sump is narrow, or weight and portability across a working site is a daily consideration, the PL080003 achieves the same maximum flow rate as the 750W model in a significantly more compact and lighter package.
The PL080003 uses a steel plate stretch motor housing rather than the aluminium alloy die casting used in the 500W and 750W models. This construction produces a narrower, shorter body whilst housing the motor and components needed to drive a 250 L/min impeller. In practice this matters when lowering the pump into a confined sump or narrow excavation where a wider pump would not sit correctly, and when carrying the pump repeatedly across a large active site where every kilogram counts over a full shift.
250 L/min max flow rate: Matches the maximum output of the 750W model at 530W rated input. Moves water rapidly from excavations and sumps at low to moderate head heights.
Steel plate stretch motor housing: The most compact construction in the MAX 110V range. At 185mm wide and 305mm tall the pump body is significantly smaller than the 500W and 750W aluminium alloy models, suited to confined spaces and narrow sumps.
Integrated automatic float switch: Activates the pump when water rises to the trigger point and cuts it when the level drops. Confirmed in the manufacturer's exploded diagram as a standard fitted component on the PL080003.
13.0kg gross weight: The lightest model in the MAX 110V submersible range. Easier to transport, lower and retrieve repeatedly across a working shift.
50mm (2") outlet: Standard 2" hose connection compatible with the most common site discharge hose sizes.
6mm particle handling: Passes particles up to 6mm without impeller blockage. Suitable for water containing grit and fine aggregate debris. Not suitable for slurry or sewage.
IP68 rating: Fully sealed for continuous submersion at depths up to 5m under normal operating conditions.
Thermal overload protection: Cuts the motor automatically if the pump overheats. Resets after cooling.
10m power cable: Standard site reach from a 110V transformer.

Site managers, groundworkers, and civil engineers on UK construction sites who need a high-flow 110V pump in a compact, lightweight body. Particularly suited to tasks where the sump or excavation is narrow and a wider pump body would not sit correctly, where the pump is carried between multiple work locations across a large site during a single shift, or where a high flow rate is needed but head height does not exceed 11m. PL080003 delivers the same 250 L/min maximum output as the 750W model in a body 54mm narrower and 84mm shorter, at a weight 6kg lighter.
Dewatering narrow excavation trenches and confined sumps where the 239mm width of the 500W model would not fit correctly.
Rapid water removal from standard foundation excavations and trenches on construction sites at head heights up to 11m.
Moving the pump between multiple dewatering locations across a large site repeatedly during a shift, where lower weight improves operative efficiency.
Pumping accumulated water from underground chambers, inspection pits, and service ducts with restricted access openings.
Temporary drainage during rainfall on civils and utilities sites where surface water must be cleared quickly to maintain progress.
Emergency floodwater removal where rapid deployment from a van or site store is required.
Step 1: Ensure the pump is prepared and positioned correctly before connecting to the mains supply. Never allow the pump to operate if the water level has dropped below the minimum level required, as this may cause damage.
Step 2: Check the water for debris larger than 6mm. The PL080003 has a 6mm maximum particle size, one millimetre less than the 500W and 750W models. Remove stones, aggregate fragments, or debris above this size before lowering the pump.
Step 3: Connect a 50mm (2") discharge hose to the outlet. Secure with a hose clip. Confirm the total vertical rise of the discharge route does not exceed 11m.
Step 4: Connect to a mains supply via an RCD. Confirm a 110V AC supply is available from a site transformer before connecting.
Step 5: The integral float switch will turn the pump off automatically when the water drops below a certain level. Disconnect from mains power at that point. Note: some models may run continuously once powered on, ignoring the float switch. Switch off manually when needed.
Step 6: If the pump stops due to overheating, the thermal overload protection has activated. Disconnect from power, allow the pump to cool for approximately 20 minutes, and investigate the cause before reconnecting.
Step 7: Note that maximum horizontal distance and flow rate are affected by head height. Head height is the vertical distance between the water surface and the highest point the water is pumped to, regardless of hose length. As head height increases, both flow rate and pumping distance decrease.
Exceeding the 6mm particle size limit: this model handles particles up to 6mm, one millimetre less than the 500W and 750W models. Remove all debris above 6mm from the water before starting.
Connecting to 230V supply: a 110V AC site transformer is required. Connecting to 230V mains causes immediate and permanent motor damage.
Running the pump dry: operating without water submerging the pump causes rapid overheating. Keep the pump submerged throughout operation.
Exceeding 11m head height: above 11m vertical head the flow rate reaches zero. Plan the discharge route to stay within this limit.
Carrying the pump by the power cable: always use the carry handle. Lifting or lowering by the cable stresses the cable entry point and can cause water ingress over time.
Always ensure the pump has completely stopped and is disconnected from mains power before attempting any cleaning, inspection, or product care. Technical maintenance and servicing may only be performed by qualified personnel. Connect only via an RCD-protected 110V transformer. Do not handle the pump while standing in water. Do not use for flammable liquids, corrosive fluids, or sewage.
Periodically flush the pump with clean water, particularly after long periods of inactivity or extended use. If used in debris-heavy water, rinse thoroughly after each use. Check and clean the impeller housing regularly to remove any debris build-up. Wipe the exterior with a dry or damp cloth only. Do not use solvents or harsh chemicals. Ensure the pump is completely dry before storing. Store away from direct sunlight and frost. For permanent installations, run the pump weekly to prevent motor issues from developing. Never allow water inside the pump to freeze, as this can cause permanent damage.
Q: How does this pump compare to the 500W model if both have a 2" outlet?
A: The 530W model delivers 250 L/min versus 210 L/min for the 500W, a 19% higher flow rate at a comparable power level. The 530W model also has a more compact body at 185mm wide and 305mm tall, compared to 239mm wide and 356mm tall for the 500W, and is lighter at 13.0kg versus 12.6kg gross weight. The trade-off is a slightly lower maximum head height: 11m for the 530W versus 12m for the 500W. If head height is not a constraint, the 530W is the better specification for high-flow applications in tight spaces.
Q: Why is the maximum particle size 6mm on this model rather than 7mm?
A: The PL080003 uses a steel plate stretch motor housing with a different impeller configuration to the aluminium alloy die-cast 500W and 750W models. The impeller clearance on this construction passes particles up to 6mm reliably. Check the water for debris above 6mm and remove it before lowering the pump. For water with consistently larger particles, the PL080001 or PL080002 with 7mm particle handling is more appropriate.
Q: What does steel plate stretch motor housing mean compared to aluminium alloy die casting?
A: The two terms describe different manufacturing methods for the motor housing. Aluminium alloy die casting injects molten aluminium into a mould to produce a shaped part, typically resulting in a thicker-walled, heavier housing. Steel plate stretch forming shapes steel sheet into the housing profile, producing a lighter and more compact result for the same internal volume. The steel plate housing in the PL080003 is what gives it its narrower 185mm width compared to the 239mm of the aluminium alloy 500W model.
Q: What does the integrated float switch do?
A: The float switch is a buoyancy-activated control that automates the pump's operation. When the water level rises and lifts the float to a set height, it triggers the pump to start. When the water level drops and the float falls below the lower threshold, it cuts the pump. This means the pump manages water accumulation in a sump or excavation continuously and automatically without requiring manual intervention.
Q: Can this pump run unattended?
A: Yes, the integrated float switch is designed for unattended automatic operation. For overnight unattended use, confirm the discharge route is clear and free-draining, ensure the 110V supply is stable and RCD-protected, and check the cable and connections are undamaged before leaving. Note that some units may run continuously rather than cycling with the float switch; confirm behaviour during an attended test run before leaving unattended overnight.
Q: What type of water can this pump handle?
A: Clean water and water containing particles up to 6mm. Not suitable for slurry, silt-laden water, sewage, foul water, or chemically contaminated water. For water containing sediment or hydrocarbon contamination, use appropriate dewatering filters in line with the discharge.
Q: What triggers thermal overload protection and what should I do?
A: Thermal overload cuts the motor if internal temperature exceeds a safe threshold. Common causes include running dry, a blocked impeller, or extended continuous operation in high ambient temperatures. When it activates, disconnect from power, allow the pump to cool for approximately 20 minutes, identify and resolve the cause, then reconnect.
