Great pump at a fraction cost of the big brand

By: on 19 April 2017
We own several honda and yanmar engine pumps and recently we were looking for a cheaper alternative pump. I have seen Thornado pump a couple times on a water truck. I contact the company and the sales team is very professional and good product knowledge. I decided to give it a try. The pump is really well built. Works really well without any problem. The pump has been on the job for more then 10 weeks now. This pump is seriously as good ad the big brand pump.

Great pump

Pump works really well but the strainer for the suction hose need to be made of metal instead of plastic it is simply not strong enough.

Amazing pump - Thornado 4 inch diesel water transf

Great little unit. Bought 2 units of the Thornado 4 inch diesel water transfer pump for our farm to transfer water from a dam approx 300m. The pump is really robust. Electric start with this diesel engine is a champion mate. We own this pump for about 6 months now. And i think its time to provide our review. HIGHLY RECOMMENDED & VALUE FOR MONEY!
