    You will need one that is suitable for potable water, which limits the choice considerably.  Such a pump could also be used for a hot water recirculation loop and a quick Google suggested that recirculation pump yields more results than destratification pump.

    Would the new one fit with existing pipework or would you need to make changes.
    Grunfos pumps do a good range and have been around a long time.
    You can downloads specs and sizes from website.

    remember over the life time of  use the energy used between types of  pumps will add up ,so is  worth investing in as low energy one that will do the job

    Also worth considering the payback time.  If you destratify the hot water you can keep your cylinder hotter so if you are heating it with free solar power you save money on days when a sunny day is followed by a cloudy day.  If there are 50 such days a year and you save 50p worth of electricity each time then you will save £25 per year.  If the pump cost you £125 it will have paid for itself after 5 years.  For "green" investments a five year payback period is not bad, provided the pump lasts significantly longer.  But I have no idea if my estimates are accurate.
