Need Chiller advice please!

[Reesj]

I setup my tank recently. As I'm from Sri Lanka and my closed off hood give little room to cool the water from evaporation the temprature creeps up to 29 (Few more I bet by May) and I decided to Get a Chiller (Hard pill to swallow as quite expensive for my budget capital and also Exlectricty bill).

I have a SunSun 50 gallon tank that came with in build sump setup.
I was hoping to setup the Chiller from Last Chamber of Sump (After water gets cleared of particles) water pump-> Chiller-> connect to Display tank return . (Hopefully this is fine even when power out ?).
The Chiller is hailea HC 100A- Rated100L-200L.

The problem is the Pump I already have is 1400LPH and The chiller is rated 200-1000Lph.
I looked around, If I can find a 1000Lph waterpump cheap but can't find anything. Best they have is 1350lph or 700lph.

But the Chiller will have to Pump the water about 5 feet to the Display. This will also reduce the Speed of the pump. From the looks of it it seems 1400lph might be in reality working slower. Also the 700lph that I might have to buy might not make the cut to pump water that high.

What Should I do. Need soem urgent help . Thanks

Edit:- sorry seems wrong section

Can you use a gate valve or similar to regulate the flow of your pump into the Chiller?

Most pumps that are rated for a certain water volume per hour never actually achieve that water volume so it is highly likely that that pump well in the real world put out less than 1000lph

I also got a stop valve thinking I can reduce the flow from that on the advice from the store that sold the chiller. The stop valve comes on 1/2 pipe size.
But the problem is that chiller reqires a small horse size which reducers don't come in.

Any idea how much flow a 1400 lps pump might have pumping the water 4.5 feet on to the Display tank ?

Often, the pump mfg. website has a graph or calculator. If not, try this:

The pump came with the Tank and I have since thrown away the pakaging L(
From that link it seems impossible to deduce the final flow.

Actually with the new lower diameter pipes of chiller the water presure seems moot point when I tried to conenct it today. I had to custome make a reducer from a lathe shop. The reducer made the speed even less.
When I measured the LPH usign a 2Ljug (had to cause it was soo slow) it came to about 225LPH. I went to the lathe shop got the reducer a bit moree wider onmiddle. Still when I came home it now sits at only 300lph.
Which sucks as my tank water volume went down as well as the overflow now making some noice to add to the insult;Facepalm;Facepalm

I don't think even addign a bigger pump will help excet get a lathe shop to make some sort of ultra thin reducer with low durability to increase the flow rate!!
Any thoughts....
