Sumas utilizes primarily IMS pumps ranging in sizes up to 12". These pumps are  capable of handling animal, vegetable, municipal, pulp and paper wastes in a wide array of consistencies ranging from liquid slurries to semisolids. Impeller heads can vary depending on the type or class of material, allowing a versatile use of the pump.  Materials that contain debris such as plastics, paper and/or semi-solid chunks, that are small enough to pass through the pumps, are ground and shredded using one of our Muffin Monsters, that likewise range in sizes up to 12". These machines are extremely effective in breaking down materials commonly found in wastewater treatment plants before the materials are removed for beneficial reuse or land application purposes.
