Which Trotec water pump fits the job?
Updated: October 2026
A borehole, a rain butt and a flooded cellar can all contain water, but they do not need the same pump. If you are deciding which Trotec water pump to buy, start with where the pump will sit and what the water contains, not the largest litres-per-hour figure. The [Trotec pump comparison](/hub/cooling/trotec-pump) covers eight amazon.co.uk listings across five duties. This page helps you close the unsuitable listings before you compare price, head or customer ratings. The Products Compared editorial team compiled these rows in October 2026 from those listings. We did not run a laboratory test.

Start with the job, not the litres
Flow figures only make sense when two pumps perform the same kind of work. The TWP 4006 E is a clean-water submersible with a stated flow of 7,300 l/h at about £49.50. The TDP 370 E costs about £230.19 and states 5,100 l/h, yet it is a slim deep-well pump intended to raise water under pressure from a borehole. Ranking those two by flow would be like choosing between a bucket and a hose reel by capacity alone.
Ask where the pump will sit, and whether the water is clean or could hold mud and leaves. A borehole also needs a long, narrow pump working against vertical head. Those answers lead to five duties: deep well, surface garden pumping, domestic pressure supply, submerged clean water or submerged waste water.
Five duties in this set
For a borehole, begin with the four TDP listings. The TDP 370 E and TDP 750 E both state 5,100 l/h and a 23 m cable. The TDP 5500 E and TDP 7500 E use different flow, head and power lines. Continue with the Trotec deep-well pumps before choosing between them.
For a rain butt, pond or cistern while the pump stays dry, the TGP 1005 E is the surface garden pump. Its title states 3,300 l/h, 4.2 bar and 7 m suction. Fill it before use. It is not a pump to lower into a flood.
Part 4610000195 is the pressure-set listing. The bullets describe a vessel and pressure switch, although the title does not say pump. For submerged use, the TWP 4006 E is titled for clean water and the TWP 11000 ES for waste water.
Keep figures inside one duty
The TWP 11000 ES states up to 20,000 l/h, but that does not make it a borehole pump. Strainers that refer to particles larger than 1.8 mm, and the TGP 1005 E pre-filter from 1 mm, do not make those products dirty-water pumps.
Treat oddly formatted fields as warning labels. The TDP 370 E lifting field prints 40 meters Metres, beside a highlight of 4 bar and 20 m immersion. The TDP 750 E prints 5E+1 Metres. Keep both lines and check the model manual.
Measure the narrowest part of a borehole. Bullets describe a 10 cm body and a well of at least 12.5 cm, while the TDP 750 E dimensions are 12.5 × 12.5 cm. None of the eight listings names a hose. The TDP 370 E fitting is described for 1/4 inch hoses, and the TDP 750 E for 1 1/4 inch. No listing states a BS 1363 plug or drinking-water approval.
When a pump is the wrong next step
Ask a competent electrician or well contractor to deal with fixed wiring you did not install, a repeatedly tripping RCD, an unknown rising main, or a borehole whose depth and yield have not been established.
These listings provide no drinking-water approval. If water is already entering an occupied building, avoid electrical hazards and contact an appropriate professional. Once the type is chosen, follow the Trotec pump setup guide.
Match the duty, then the price
Stay with the four TDP listings for a borehole, the TGP 1005 E when the pump stays dry, and a TWP title when you lower the pump. Compare price only after the duty matches. A qualifying amazon.co.uk purchase may earn us a commission at no extra cost to you.
Common questions
Which Trotec pump fits a borehole rather than a water butt?
Choose among the four TDP deep-well listings for a borehole, after checking diameter, head, cable and outlet. For a water butt with the pump kept dry, the TGP 1005 E is the surface option. If the pump will be lowered into clean butt water, the TWP 4006 E is the relevant submersible listing.
Can the TGP 1005 E empty a flooded basement?
It is a surface garden pump that must be filled before use and kept out of the water. A TWP submersible is the more relevant type for drainage. Use the TWP 4006 E only for clean water. The TWP 11000 ES is the waste-water title, although its amazon.co.uk listing gives no solids size.
Why is 7,300 l/h not better than 5,100 l/h?
The 7,300 l/h TWP 4006 E and the 5,100 l/h TDP models do different work. The TWP moves clean water while submerged. A TDP raises water from a narrow borehole against head. Compare flow only after duty, fit and required head match.
What is listing B085364BJS for?
Part 4610000195 and the bullets identify a pressure set with a vessel and pressure switch. The listing gives no head or pressure in bar, so verify the matching documentation before you treat it as a ready service-water pump. The amazon.co.uk title does not say pump.
Should you trust the amazon item-type field?
Not by itself. Several fields conflict with titles, model numbers or bullets. Check the exact model and part number, then read the correct English manual. Keep listing and manual figures separate where they disagree.
Does a higher price mean a better pump?
No. The highest price in this set belongs to a deep-well model, the TDP 5500 E at about £345.28, while the lowest belongs to a clean-water submersible. Each can be the right purchase for its own duty and useless for another. Compare price only among products that fit the same job.
