High Performance, Long Lasting Pumps

Durable and Efficient

The AMP® Extended Run Semi-Trash Pump is a versatile workhorse ready to tackle a variety of jobs. To ensure the best performance, longer life and smoother operation, we gave this heavy-duty water pump a cast iron impeller and volute to increase pump life in semi-trash situations. We also added a multi-directional discharge that puts fluids where you want them.

Handles the Toughest Jobs

The high-end silicone carbide mechanical seals in this AMP®Extended Run Semi-Trash Pump are harder, tougher and stronger than common aluminum oxide seals and have superior resistance to corrosion, wear and heat so you can use it in all kinds of situations. It also has our cutting-edge check valves that hold a prime when the pump is not running to quickly get you back up and pumping.

Built Tough

Because job sites can be dangerous and accidents happen, we knew you’d want to protect your pump. This is why it is has a fully welded rugged steel roll cage. It gives the pump maximum protection at the jobsite and while transporting. The wide base gives rock-solid stability.
