About Us

Thompson EnviroprimeĀ® trash pumps are engineered to provide consistent and dependable service on the most difficult job sites. These pumps are used in a wide variety of applications including open pumping and sewage bypassing where moderate air handling is required. The pumps are capable of pumping liquids with high abrasives or solids as large as 3.35" in diameter. EnviroprimeĀ® trash pumps are specifically designed to prevent pumping fluid, such as sewage, from entering the venturi and eventually onto the ground making the EnviroprimeĀ® environmentally friendly and safe.
