The Bermuda Filterforce Duo pumps are built to last with an outlet, and also an inlet designed for attaching to a skimmer.

As with the Filterforce, the running costs on the Filterforce Duo are also very low, complete with a 3 year guarantee (excluding impeller & shaft).

An extremely durable range of powerful, specialist filter pumps. All 5 models are extremely low wattage starting with the great value Filterforce Duo 3500 all the way up to the 10000 liters per hour model.

Colin Ellson Asked:

Does the Bermuda 4500 pump come with a fused plug or is it open ended to connect straight to an outdoor socket? If a plug is used, what fuse would be needed?

We Replied:

Dear Colin Thank you for your question. This unit will come open ended, it is against EU regulations to sell pond equipment with a moulded plug. A 3 amp fuse would be sufficient. Should you wish to contact us further or to place an order, please call us on 0121 355 7701. Thank you for using our online Q&A system. Kind regards Dan Everton

Denise Guest Asked:

For about two weeks my 4500 fire force duo has worked for about 10 hours then stopped. I've cleaned it although it doesn't look clogged but it still doesn't pump. I bought it about 18 months ago, what do you suggest?

We Replied:

Dear Denise Thank you for your question. If the entire pump has been cleaned and the fault is still present, then there must be a fault with the main pump. If the unit is still under warranty, show the company you bought it from a bank statement showing the amount being debited on the day of purchase and they should swap it for a new one providing the tests in-store prove conclusive. Should you wish to contact us further or to place an order, please call us on 0121 355 7701. Thank you for using our online Q&A system. Kind regards Dan Everton
