The ACRK series is a high-lift multistage centrifugal pump for high-precision machine tools that need high coolant pressure for cooling and flushing the workpiece. Wetted parts are stainless steel and the mechanical seal uses FKM, so it holds up to heat and long run times. Typical uses: CNC lathes, machining centers, grinders, parts washers and filtration systems.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003e60 Hz build.\u003c\/strong\u003e This listing is for 60 Hz power, the standard in the US.
