Tsurumi C Series cutter pumps

Tsurumi has produced the C Series range of cutter pumps, designed to chop up oversized, fibrous waste material. The three-phase, heavy-duty pumps feature a bore ranging from 50 to 100 mm. The largest pump in the range has a capacity of 2750 L/min and a max head of 26 m.

The series incorporates a large open-channel impeller with a cutter mechanism. A sintered tungsten carbide alloy tip is brazed on the impeller vane. As the impeller rotates, the vane slices against the serrated edge of the suction cover, chopping fibrous matter into small fragments that won’t clog. The cutter impeller chops through sewage, rawhide, plastic rags and other materials in seconds.

The series include features that extend the life of the pump, including an anti-wicking cable entry that prevents water from entering the motor if the power lead is damaged or the end of the cable is accidentally submerged. A double silicon carbide seal is standard on all models. Both seal surfaces are submerged in an oil chamber, away from the pumped liquid. This ensures lubrication and protects ingress of foreign materials.

The oil bath features an ‘oil lifter’ that increases mechanical seal longevity. The lifter ensures both the upper and lower seals are lubricated and cooled, even if the oil level in the chamber is low.
