We get equipment donations regularly and sometimes the sumps have utility pumps in them that push water back to a tank. IDK why they are called utility. They are magnetically driven, very similarly built to other tank and pond pumps but these do tend to produce higher head pressure and lower flows at the same wattage. Here are 1200 GPH and 1800 GPH examples of ours:

I think we must get well and truly ripped off for electricity cost here in the uk. If I were considering running any pump at 110 watts for any length of time it would have to be moving at least 6 -10 thousand gallons to be even considered as an option. And then just that one pump is gonna cost me around 70p per day to run or £21 per month, £252 a year!

Are you sure about that? Are we talking about a 110-watt pump? In constant use, that would consume less than 3 kilowatt-hours per day. In these parts, that would cost about 30 cents per day, or about $100 per year of continuous use.

I haven't had my coffee yet...but I think one of has a decimal floating around somewhere...:)

Yup, 25p per kWh plus a daily standing charge now that the price has come back down again.

Hence my aversion to seemingly cheap “utility” pumps. The word to me says expensive to run rather than poor at doing the job.

Wow...you are paying roughly 4.5x as much for electricity as I am...and I am always complaining how expensive it is!

I am strictly comparing the cost of the power itself; we have a handful of additional charges, surcharges, fees, taxes and sundry add-ons, but those charges are mostly poorly explained and cunningly presented things that serve to complicate the interpretation of the monthly bill, so I didn't think to include them. As a Canadian, I am fully accustomed to being reamed/robbed/ripped-off by any Crown corporation, so I have become jaded...:)
