  • Powerful Engine

When you first look at this semi-trash water pump’s specs, you’ll notice the mighty engine. The Generac 208cc 4-cycle OHV engine delivers the whooping 158 gallons per minute.
No doubt, this semi-trash water pump is perfect for tough challenges of any type. For increased comfort, the manufacturer has included a low-oil shut down to protect the engine from damage. Also, let’s not forget the difference in the impeller design. The four-vane design allows the gadget to pump larger particulate.

  • Large Capacity

Of course, power doesn’t matter unless there’s some formidable capacity to use. Well, the 3.4-gallon steel fuel tank provides up to five hours of runtime in optimal conditions. Perhaps, this characteristic is more than enough to empty your garden pond.

  • Portable and Lightweight

Furthermore, the Generac ST20K-6822 wouldn’t be so attractive if it wasn’t for its portability and weight. While it’s not the most lightweight semi-trash water pump in the class, it’s still easy to carry. As for the weight, the 73.9 lbs on the machine is still too heavy to carry. Thankfully, the manufacturer has included two wheels to make it more maneuverable. Also, you can use the folding handle for effortless transportation.

  • Durable

Yet another advantage, dealing with heavy-duty tasks, opts for more durable construction. Arguably, the manufacturer has decided to bet on the traditional open-frame design. Buyers can enjoy the 1-inch frame that can withstand harsh weather.
Moreover, the silicon carbine mechanical seal is durable enough to prevent damage from abrasive particles. That’s one of the reasons why it’s essential to get this semi-trash water pump for unfiltered water.

  • Easy to Assemble

If you’re not so tech-savvy, you may find the assembling of this machine to be a huge relief. What’s more, the pump comes with a pre-measured amount of oil. Within a few steps, you’ll be ready to go.
