What the two listings print

On amazon.co.uk the GS 4003 P shows about £34.65, 8,000 litres per hour, 5.5 metres, 25 mm, 230 V, 7 metres of immersion and 2.3 kg. The star line is 4.3 from 271, and the written reviews are labelled Germany. The GC-DP 3325 shows about £37.97, 330 W, 9,500 litres per hour, 6 metres and 25 mm, with an adjustable float. The voltage line says 120 V, and the star line is 4.4 from 1,050. Neither price includes a hose.

Where the paperwork disagrees

The Güde manual for article 94638 prints 400 W, 4 metres of immersion and 3.25 kg. The amazon listing prints 7 metres and 2.3 kg, and it does not print 400 W. Do not average them. The listing prints a male 1¼ inch port and the manual a female thread. Güde’s English retailer page, priced in kroner and so not a UK price, describes a float and about 25 mm left. The amazon file does not confirm the float. Einhell UK is not a 120 V description, and 1,050 UK reviews do not repair that line.

When to open the GC-DP 3325

Open the GC-DP 3325 when you want United Kingdom review text for a modest 25 mm drain, and when the plate is 230 V with a BS 1363 plug. A 120 V plate means you do not keep it. Particle size and head, before this pair, are on the dirty water pump buying guide.

When to open the Güde, and when to leave both

Open the GS 4003 P when you accept the conflicts. Treat 7 metres and 2.3 kg as unverified against the manual’s 4 metres and 3.25 kg. The listing does say 230 V, which the Einhell listing does not. Shock comments stay labelled Germany. They are not a UK failure rate. Leave both for gravel or a sump that runs all winter. The 35 mm pick is on the best dirty water pump page. Fitting the hose is on how to use a dirty water pump.

Common questions

Which is better for a cooled tub or a small pond drain?
For that 25 mm job, choose the GC-DP 3325 at about £37.97 if the plate matches UK 230 V mains and a BS 1363 plug. You then have 4.4 from 1,050 reviews and a 6 metre head. Choose the GS 4003 P at about £34.65 only if you accept 4 metres of immersion in the manual against 7 metres on the listing, and you can live without UK review text. Neither is the muddy-water pump. Both leave a layer you will mop.
Is the Güde more powerful because the manual says 400 W?
The manual prints 400 W. The amazon.co.uk listing does not. It prints 0.53 hp, 8,000 litres per hour and 5.5 metres. The Einhell listing prints 330 W, 9,500 litres per hour and 6 metres. Do not treat 400 W as the amazon specification. For a short drain, the Einhell’s UK reviews are the stronger evidence, provided the voltage plate is right.
Why does Amazon say 7 metres immersion and the manual 4 metres?
They are different documents. The listing says 7 metres and 2.3 kg. The Güde PDF says 4 metres and 3.25 kg. Do not average them. If you must sink the pump deeper than 4 metres, do not rely on the title until the plate agrees with the manual. Einhell UK states 7 metres of immersion for the GC-DP 3325. That is a third document, and it does not settle the Güde figures.
Can I trust 4.3 from 271 on the Güde?
Not as British buyer opinion. The file marks those reviews as Germany and contains no United Kingdom review text. The GC-DP 3325’s 4.4 from 1,050 is the UK count in this pair. Stars do not describe your socket or a lab test. Read the voltage line and the particle size before the stars. A Germany-labelled 4.3 does not outrank a conflict printed on the listing.
Will either water the lawn?
Einhell UK says the GC-DP 3325’s 0.6 bar is not enough for a lawn sprinkler. The Güde manual forbids pressure boosting. Both move water a short distance to a lower outlet. They are not sprinkler pumps or house boosters. If the lawn is the job, leave this pair.
Which leaves less water?
There is no side-by-side measurement here. Güde’s English retailer page says about 25 mm left. UK reviews of the GC-DP 3325 describe the last 20 to 30 mm. Treat that as the same kind of leftover. A claim of about 1 mm belongs to a different Einhell, the GE-DP 7035 LL, and it needs a hard base. For this pair, plan a mop or a brush for the film.
When would I ignore both and buy a 35 mm pump?
Ignore both for gravel, leaves or cellar silt that will jam a 25 mm intake, or for more than about 6 metres of head in one lift. The 35 mm review-volume pick is the GC-DP 7835, on the best page, at 8 metres and about £50.50. Also leave this pair for a sprinkler, for drinking water, and for a pump that must stay in a cellar sump. The Güde manual rules those duties out, and the GC-DP 3325 is the same modest class.
