What is the maximum temperature of water this pump is designed to pump, please?

As I understand it this is a cold water pump. Therefore I only use it for water at is at less than 25 c. It be capable of higher but it's not intended to run a hot water system, were hot water passes through the pump. My pump is fitted before the water heater so pushes cold in to water heater and hot is forced hot enablinng one pump to operate hot and cold .

Are the screw thread fittings in the photo included with the pump?

Yes they are in the two I purchased - not sure about this particular pump as the supplier tends to blend feedback across all the pumps

I need to do ground water sampling. Would this be able to pump groundwater from as deep as 40m up a 10mm hose to ground level?

It's physically impossible to suck water up 40m, even with a perfect pump. If you create a perfect vacuum at the top of the hose, the water will only be pulled up 10m. To pump water up higher, you need to put the pump at the bottom of the hose, where it can *push* the water up. This particular pump would then be able to push the water up about 30m.
