The Hevvy/Toyo HT Twins Series Submersible Slurry Pump is a versatile dewatering system designed to extract/transport media with up to 40% solids (Class 1 & 2 slurry rating). The HT Twins Series comes in 3 through 50 HP configurations, with discharge port sizes of 3 or 4 inches, depending on configuration. High Chrome impellers and other wear components vastly extend the service life of this model. This includes a durable agitator, preventing build up on the sump floor and thereby reducing maintenance required. This pump features thicker walls to withstand heavy abuse, and large internal clearances ensure smooth passage of mediums with higher concentrations of solid material. Balanced radial forces allow for longer bearing and seal service life. Each unit's motor has run dry capability, with inbuilt thermal protection. Variable voltages available with all models.
