Replacing Water Pump

[Secoast]

Hi all.
I'm suffering from hunting and an increase in noise from the hot water/central heating pump. At least I'm pretty certain its the pump.
The crurrently fitted unit is shown below in the first link. This has been installed for nearly 6 years. I've decided to replace it but justwondered what the difference is between this unit and the similar 55/130 unit shown in the second link below. I can see a small difference in flow rates, but other than that is their any reason not to go for the cheaper option.

Any advice greatly appreciated.

The only difference is the first one is newer

The second link it's probably new old stock

That's what I suspected.
