Graymills MSPR5-1.0F

Vertical Coolant Pump. Graymills pumps are typically found on OEM machine tool equipment and are thus well suited for replacement or retrofit machine tool pumping applications. They are high pressure vertically immersed multi-stage booster pumps. These pumps can also be used on other industrial applications requiring a vertical cast iron or stainless pump. The Graymills MSPR series provides steady, pulsation-free coolant delivery that expedites chip removal and heat dissipation needs. These pumps permit increased feed rates by preventing thermal shock to cutting tools and lengthening tool life substantially.

MSPR pumps are designed for extended service life. They are manufactured with long-lasting cast iron in the discharge head and suction head. Corrosion resistant 300 series stainless steel and thermoplastic internal components are encased in a stainless steel shell. The mechanical seal has carbon/silicon carbide faces, FKM elastomers, and 300 stainless steel parts. Abrasion resistant impellers and diffusers are high strength glass-filled thermoplastic. By attaching the suction head and discharge head to the multi-stage body with O-rings and threads, rather than glue and welds, this design is easy to disassemble, easy to maintain.

MSPR pumps can be combined with 21, 38 or 50 gallon Graymills tank kits to create a total circulating system.
