Best Bestway filter pump for a UK above-ground pool

Updated: 21 October 2026

Five Bestway pumps are on amazon.co.uk in this set, from £37.49 to £305.07, and three of the cartridge pages share one 3.8 from 421 review block. That is a poor way to crown a best Bestway filter pump. The useful split is smaller: a cheap 220–240 V cartridge for a 32 mm pool, a step up that states a UK plug, a dearer cartridge with adaptors, and two sand tanks whose voltage line is blank. Prices are the 19 October 2026 shelf prices. The [Bestway filter pump](/hub/pool-care/bestway-filter-pump) comparison carries the full rows. This page names who should buy the £37.49 pump and who should leave it. A qualifying purchase can earn a commission at no extra cost to you.

Best value when the pool is 1,100–8,300 L

The best-value listing, if your pool is in that band and the hose is not 38 mm, is the Bestway 58381, B0CDXX79F7, at £37.49. The bullet states 1,249 L/h (330 gal/h) on a 16 W, 220–240 V motor, for 1,100–8,300 litres. It names a Type I cartridge, 58093. Whether that cartridge is in the box is not stated. There is no adaptor, and the page says the pump cannot connect to a 38 mm hose. The 3.8 from 421 is one copied block on three ASINs. Skip this pump when the hose is 38 mm or you need the plug type printed. How the six-hour sum sits against 1,249 L/h is on the buying guide.

The £49.99 step-up that states a UK plug

Twelve pounds and fifty pence more buys the Bestway 58383, B0CDXTLDD9, at £49.99. In this set it is the only listing that says the item has a UK plug, so it is the top pick when that sentence is your rule. The included-components line is 220–240 V and 29 W, with pump flow of 2,006 L/h and system flow of 1,817 L/h. The title says a Type II cartridge, 58094, is included, plus two 32 mm hoses. It still cannot connect to a 38 mm hose. The same page prints 1,100–14,300 litres and 1,100–8,300 litres. An attribute line says battery powered and 11 g. Ignore it: the pump is corded and the unit count is 3,000 g.

Who should pay £133.92

The Bestway 58389, B0CDXRX6WS, is £133.92 and states 5,678 L/h, described as system flow, at 220–240 V and 86 W, for 1,100–31,700 litres. Open it when the pool is larger than the 8,300 litre line, or when you need adaptors. The listing includes adaptors for 38 mm and 32 mm valves, and the same included-components line also says it works only with 1.5 in / 38 mm threaded valves. A Type III cartridge, 58012, is named. Whether it is in the box is not stated. The plug type is not stated, so this price does not buy the UK-plug sentence on the £49.99 listing. An older 1,500 gal Flowclear page, B08CB3NML2, is a different ASIN and was unavailable.

When sand is the pick instead

Sand is a different job. The £156.47 pump states 950 GPH for 300–4,800 gallon pools. The £305.07 pump states 2,200 GPH for 300–11,200 gallons. Neither states litres, voltage or a plug. Sand is not in the box. US-marked reviews are not British opinion. Sand is the pick only when you will add silica #20 or Polysphere, you accept a blank voltage line, and you would rather backwash than rinse a cartridge. It is not the default best pump. Fineness and the missing sand are on the cartridge versus sand page.

Common questions

Which Bestway pump is the best value under 8,300 litres?
The 58381 at £37.49, if the pool is inside 1,100–8,300 litres and the hose is not 38 mm. It states 220–240 V, 16 W and 1,249 L/h, and it names a Type I cartridge, 58093. The plug type is not stated, and the cartridge may not be in the box. The 3.8 from 421 reviews is shared with two other ASINs, so do not treat that star line as proof this model alone was tested 421 times in the UK.
When is £37.49 the wrong buy?
Skip it when the pool hose is 38 mm, because the listing says there is no adaptor and it cannot connect. Skip it when you need the words UK plug on the page. The shared review block also calls the flow too little for a skimmer or for running overnight, so a pool that depends on a skimmer is a poor match for this cheap cartridge even when the litre range looks right.
Who should pay £133.92 for the 58389?
Someone whose pool sits toward 31,700 litres, or whose valves need the included 32 mm and 38 mm adaptors, and who accepts that the plug type is not stated. The flow line is 5,678 L/h at 86 W, described as system flow. One sentence on the same listing limits the pump to 1.5 in / 38 mm threaded valves. The shared 3.8 from 421 is not a reason by itself to pay that much.
Is the £156.47 sand pump better than the cartridges?
Not as a default. It states 950 GPH for 300–4,800 gallons, sand is extra, and voltage and plug are not stated. The six review bodies in the extract are marked United States. It can suit you if you want a six-position valve and you will buy sand separately after you have checked the supply. It does not beat a £37.49 or £49.99 cartridge on plug clarity.
Can I rank these pumps on the 3.8-star score?
No. That 3.8 from 421 is one copied block on the 58381, 58383 and 58389. It is not three UK results. The sand listings show 4.4 from 32 and 4.5 from 169, and the review bodies in the extract are marked United States. Rank on stated voltage, plug, flow, hose and whether sand is in the box. The stars do not separate these five pumps cleanly.
