The Graymills IMV08-E is a compact, vertical immersion coolant pump rated at 1/8 HP, designed for machine tool and industrial recirculation systems. It runs on 115/230 V single-phase power and operates at roughly 3,450 RPM, delivering up to 10 GPM of flow.

Built with a cast-iron pump body, a carbon-steel shaft, and a plastic impeller, the IMV08-E is rugged and designed to tolerate liquids containing fine contaminants — with no internal bearings or seals immersed in the liquid.

Its compact size (overall length ~ 6″; overall height ~ 11-13/16″) makes it ideal for tight tank installations. And with a maximum allowed viscosity of 500 SSU, it supports a wide range of coolants and cutting fluids.

Typical Applications

• Machine Tool Coolant Systems: Circulating flood coolant for lathes, mills, and machining centers.
• Parts Washers / Wash Tanks: Used in cleaning systems where you want to recirculate wash solution or degreaser.
• Tank-Based Fluid Systems: Ideal for use in closed tanks or sumps, especially paired with Graymills’ tank systems.
