The Schmalenberger SZ Cut pump combines a proven centrifugal pump design with a cutting element and optimizes the difficult transport of aluminum chips in the coolant cycle. As the company explains its special advantages, a cutting element made of hardened steel at the suction opening cuts the aluminum chips suspended in the coolant. This prevents a clogging of the pipeline by unbroken knotted chips and improves the transport of coolant with chips. The mixture can subsequently be pumped to a filtration system where coolant and aluminum chips are separated. The simultaneous suction, cutting and the joint transport of coolant and chips serves to minimize the space requirements and lower the energy and investment costs. The manufacturers specify a flow rate of 250 to 1,000 l/min and a delivery head of 8 to 35 m. The pump features a body made of cast iron, an impeller designed with wear-resistant stainless steel, and a carbide cutting element.

The simultaneous suction, comminution and the joint transport of KSS and chips is intended to minimize space requirements, while at the same time reducing energy and investment costs.
