The best bronze circulating pumps, compared.
Top pick: Hanicks 97549426 – Only title that states WRAS approved, with 6 m head, 65 L/min, 93 W and 10 bar printed. Best value: Trident TP256-130BR – Lowest price at about £89.99, with 6 m head, three speeds, IP42 and 4.1 from six reviews. Updated October 2026.
A bronze circulating pump is the circulator on a domestic hot water secondary return. The parts that touch the water are bronze. It is not the cast-iron pump on a radiator loop. You look one when a long pipe run wastes water at a distant hot tap, when a cylinder loop needs replacing, or when a drawing specifies a bronze pump on a secondary circuit. They cluster around 6 m head and three fixed speeds, and one title states WRAS approved. Port length and unions are not printed, so measure the pump you are removing. The order of those checks is in the [bronze circulating pump buying guide](/hub/heating/bronze-circulating-pump/sub/bronze-circulating-pump-buying-guide). This page is the six-row table from those listings. Bronze is the metal in contact with water you might drink. Port-to-port length of 130 mm and 1½ inch unions are the usual mechanical target, but only one card prints both. Two cards print a maximum flow, either 57 or 65 L/min. The rest leave approval, unions or port length blank. A blank field means the listing did not print that figure, so you cannot treat the title as the specification.

Question 1 of 2
What does the job need?
Hanicks model 97549426 is the only row in this comparison whose amazon.co.uk title states WRAS approved, which matters when a landlord or maintenance contract asks for potable-water proof on the invoice. The listing prints 6 m head, 65 litres per minute max flow, 1½ inch connections, 93 W power, 10 bar maximum pressure, and TF110 °C temperature class, which is more complete than most of the other five. It scores 5.0 from three reviews, and trade-leaning comments mention good quality and fair pricing for a familiar controls brand. The box is bronze pump only, so unions are your responsibility, and three reviews is still a narrow sample. The installation note on the listing points to a qualified professional. Among the six listings on this page, this is the clearest compliance-led pick if the title wording matches your sign-off process.
Pros
Cons
Best for: Installers and landlords who need WRAS wording on the order and a full duty line on the listing.
Less suitable: Tight budgets under £95, or swaps where you must have unions delivered in the same box.
Specifications
Common questions
Does the Hanicks listing claim WRAS approval?
Yes. WRAS approved appears in the product title on amazon.co.uk for this ASIN. Check the nameplate as well. A sibling model is not this approval.
What flow rate is printed?
Maximum flow rate is listed as 65 litres per minute, with a 6 m head, 93 W and a 10 bar maximum pressure.
What do the reviews mention?
Reviews mention good quality, fair pricing, and Hanicks as a familiar heating-controls supplier. The sample is three reviews.
Circulation Pump Ltd’s SE60B lists at £150.00 with 6 m head, 57 litres per minute max flow, three speeds, 230 V supply and 10 bar maximum pressure. A bullet mentions up to five years warranty, which is unusual in this price band if the seller confirms it applies to your install type. The amazon.co.uk line shows 5.0 from two reviews, which is a perfect average on the thinnest count in the set. Application covers domestic and commercial hot water circulation, yet WRAS, unions and port length stay unstated on the listing. Replacement charts often reference this pump class, which helps trade buyers who think in cross-reference numbers rather than brands. Treat the warranty bullet as something to confirm at purchase, and weigh the two-review score against the Hanicks three-review WRAS row if compliance paperwork is the deciding factor.
Pros
Cons
Best for: Trade swaps where you want a named SE60B class pump and will confirm warranty terms with the seller.
Less suitable: WRAS-led landlord jobs, or buyers who want the most review depth per pound spent.
Specifications
Common questions
What flow rate does the SE60B listing print?
57 litres per minute maximum flow rate, with a 6 m head and three speed settings.
How many speed settings are listed?
Three speed settings. The card also states a 230 V supply and 10 bar maximum pressure.
What warranty wording appears?
A listing bullet mentions up to 5 years warranty. Confirm that the wording applies to your install before you rely on it.
Tower’s BRZPUMP sits at £115.95 with 4.6 from four amazon.co.uk reviews, the strongest star average among the mid-price rows that still show a review count. The listing prints 6 m head, three speeds, IP42, and domestic or commercial secondary hot water use. Box contents include instructions, two connecting nut assemblies and two rubber seals, which reduces the chance you finish a Sunday swap without a sealing face. Port length and connection size stay unstated on the listing, so you still need to match the removed pump physically. Four reviews is a thin base for reliability claims, and WRAS does not appear on the listing. If your priority is a slightly higher review average plus hardware in the carton, this row sits between the budget Trident and the compliance-led Hanicks price.
Pros
Cons
Best for: Secondary hot water swaps where you want union hardware and instructions in one box.
Less suitable: Compliance folders that require WRAS in the title, or tight budgets under £95.
Specifications
Common questions
What is included besides the Tower pump?
The listing includes instructions, two connecting nut assemblies and two rubber seals.
What protection rating is printed?
IP42. The card also states a 6 m head and three-speed operation on 230 V, 50 Hz.
Is this listed for secondary hot water?
Yes. Compatibility is stated for domestic and commercial secondary hot water.
The Trident TP256-130BR is the cheapest bronze secondary circulator in this set at £89.99, with a 6 m head, three speeds and IP42 on the listing. Across six amazon.co.uk reviews it averages 4.1, and several buyers describe quiet running once the loop is commissioned on a sensible speed. The listing targets domestic and commercial hot water circulation, though it does not print port-to-port length, union kit contents or WRAS wording. That leaves you to confirm 130 mm fit and seals against the old pump before you drain down. Value comments appear in the Amazon reviews, but the sample is still small compared with a trade merchant sheet. It suits a straightforward like-for-like swap when you already know the footprint and can source unions locally if the box is pump-only.
Pros
Cons
Best for: A budget bronze swap on an existing secondary return when you have verified 130 mm spacing and unions separately.
Less suitable: Landlord sign-off that needs WRAS in the title, or a first-time buy with no measurements from the old pump.
Specifications
Common questions
What maximum head does the Trident listing print?
The listing states 6 m maximum head, with three speeds and IP42 in the bullets.
Does the listing state an IP rating?
Yes. The bullets list IP42.
What do UK reviews mention about noise?
Several reviews praise quiet running in secondary hot water installs. The listing also claims quiet operation. The sample is six reviews at 4.1.
Unvented Components Europe lists the GPD25-6SQ-130 at £94.77 with clearer mechanical data than some rivals: 130 mm port-to-port, 1½ inch BSP, and a three-speed power ladder of 55 W, 70 W and 100 W. The box contents line includes brass union fittings and sealing washers, which matters on a drained secondary loop where a missing seal means an immediate callback. Duty sits in the same 6 m head class as the rest of this set, for hot water circulation. The amazon.co.uk listing carried no star line, so you are buying on specification and seller reputation rather than buyer feedback here. WRAS and IP rating were not printed on the listing. For installers who measure once and reorder the same kit, the included unions are the main reason to pick this row over a bare pump listing.
Pros
Cons
Best for: A measured 130 mm swap where you want unions and washers in the same delivery.
Less suitable: Jobs that need explicit WRAS wording in the product title before purchase.
Specifications
Common questions
What port-to-port length is printed?
The listing states 130 mm port-to-port length, with 1½ inch BSP connections.
Are union fittings included?
Yes. The box contents list the pump, brass union fittings and sealing washers.
What power steps are stated?
Three speeds at 55 W, 70 W and 100 W, with a 6 m head. The listing has no star line.
Heating Parts Warehouse lists the BritTherm 15-60/130 bronze edition at £150.00 with domestic secondary hot water circulation as the stated application. Duty figures match the common class in this set: 6 m head and 65 litres per minute maximum flow, with bronze material called out for wetted parts. The amazon.co.uk listing showed no star score or review count, so there is no buyer feedback here to cross-check noise or longevity. WRAS, unions, port length and speed settings were not printed on the listing. You are paying a premium-band price for specification alignment with 15-60/130 naming rather than review proof. It can still make sense as a named like-for-like reference if your paperwork specifies BritTherm, but verify fit and approvals on the physical label before you drain the loop.
Pros
Cons
Best for: Specified BritTherm 15-60/130 replacements when paperwork matters more than marketplace reviews.
Less suitable: First-time buyers who rely on review counts, or jobs needing WRAS in the title today.
Specifications
Common questions
What application does the BritTherm listing state?
Domestic secondary hot water circulation, with bronze material named for the wetted parts.
What maximum flow is printed?
65 litres per minute, with a 6 m head. Speed settings, unions and port length are not printed.
Is a review score available on the listing?
No. The listing had no star score or review count when the file was read.
Six amazon.co.uk listings are on this page. The score uses the star line and review count where the listing prints one, whether the card states bronze wetted parts and a WRAS line, whether head, flow, connection and unions are printed, and the shelf price against what is in the box. There is no lab test. A missing star line counts as no customer sample. The top pick is the listing whose title states WRAS approved and whose card prints a full duty line. Best value is a different listing: the lowest shelf price that still shows a star line, a 6 m head and three speeds. Weights sum to 100.
Potable-water wording
25%Bronze is the metal for water you might drink. WRAS counts only when this listing says so. A missing WRAS line is an unknown, and a sibling model does not carry approval across.
Mechanical fit
20%The usual domestic target is 130 mm port-to-port and 1½ inch unions. A card that omits them cannot be matched on paper. Measure the pump you remove before you drain the loop.
Duty match
20%Every card in this set prints 6 m head. Flow, where it is printed, is 57 or 65 L/min. Three fixed speeds are the normal control. The highest speed left on all day adds noise and heat loss.
Amazon review line
20%Stars and the review count come from the amazon.co.uk file for that ASIN. Hanicks is 5.0 from 3. Trident is 4.1 from 6. Tower is 4.6 from 4. The SE60B is 5.0 from 2. Two listings have no star line.
Price and the box
15%Shelf price in GBP is read against unions, seals and instructions. The Trident is the lowest at £89.99 and does not print a union kit. The GPD25 and the Tower list hardware in the box. Price alone, with no star line, does not decide best value.
Read potable-water wording, mechanical fit, duty and what is in the box before you compare shelf prices. A star line with two or three reviews is a weak sample. This is not a lab test, and the word bronze in a title is not a WRAS approval.
A bronze circulating pump in this comparison is a domestic hot water secondary-return circulator. Bronze is the metal in contact with water you might drink. You usually need one when a long pipe run wastes cold water at a distant tap, when a cylinder loop needs replacing, or when a drawing specifies a bronze pump on a Worcester-style secondary circuit. The six amazon.co.uk listings sit in a familiar class: 6 m head, often three fixed speeds, and prices from about £89.99 to £150.
A cast-iron central-heating pump is the wrong metal on a secondary return. Water Fittings Regulations 1999, Regulation 4, require suitable fittings where the water is wholesome. Bronze, or a stated approval on this exact listing, is the check.
The usual domestic class here is 130 mm port-to-port and 1½ inch unions. Only one card prints both. A 180 mm body will not drop into a 130 mm gap, whatever the title says about bronze.
These are three-speed pumps where speeds are printed. The top speed run continuously adds noise and heat loss. Set the lowest speed that still clears the wait at the tap, and keep the return insulated.
Start with the metal. Bronze wetted parts are what this category is for. Then match 130 mm centre distance and 1½ inch unions to the pump you remove. Head on every listing here is 6 m. Flow, where the card prints it, is 57 L/min on the SE60B and 65 L/min on the Hanicks and the BritTherm. The GPD25-6SQ-130 is the row that prints 130 mm, 1½ inch BSP, and unions in the box together. The others leave at least one of those blank.
WRAS approved in the title is a paperwork line, and in this set only the Hanicks 97549426 prints it. Confirm the nameplate. Three fixed speeds are the normal control. The GPD25 prints 55 W, 70 W and 100 W. The Hanicks prints 93 W. None of these cards prints an energy efficiency index, so do not treat a bronze body as a lower running cost than an electronically commutated pump. Unions and washers in the carton matter on the first drain-down. The GPD25 lists brass unions and washers.
Three typical situations, each with a recommendation from this comparison.
You want hot water at a far ensuite and you already know the footprint of the old pump. The Trident TP256-130BR is best value at about £89.99, with 4.1 from six reviews and several comments on quiet running. Unions and port length are not printed, so source the seals if the carton is pump-only.
You want 130 mm, 1½ inch BSP and unions in the same delivery. The Unvented Components Europe GPD25-6SQ-130 prints those figures and lists brass unions and washers at about £94.77. The listing has no star line and no WRAS line.
You want WRAS wording on the order and a full duty line on the card. The Hanicks 97549426 is the top pick at about £140.00, with 6 m head, 65 L/min and 93 W printed. The box is the pump only, and the review sample is three.
The top pick is the Hanicks 97549426 at about £140.00. It is the only listing in this set whose amazon.co.uk title states WRAS approved, and the card prints 6 m head, 65 L/min, 1½ inch connections, 93 W, 10 bar and temperature class TF110. The sample is 5.0 from three reviews, and the box is the pump only. Best value is the Trident TP256-130BR at about £89.99, with 6 m head, three speeds, IP42 and 4.1 from six reviews. Skip the Hanicks if the unions have to arrive in the same box. Skip the Trident if the invoice has to say WRAS approved.
