Model Number:

FM73HF 1/4

Quick Overview

1/4 HP 230/460V

Availability: In stock


Graymills pumps are typically found on OEM machine tool equipment and are thus well suited for replacement or retrofit machine tool pumping applications. These pumps can also be used on other industrial applications requiring a vertical cast iron or stainless pump.

FM Series pumps are capable of pumping a wide range of viscosities. They are compact, yet they offer the performance and dependability of larger pumps. Graymills’ volute design enables FM Series pumps to pump down to an extremely low level. Discharge is above the integral mounting flange. These pumps will drop through a 4 ½ “ hole supported by their integral mounting flange.

FM series pumps are available with nickel-plated cast iron pump bodies. Aluminum pump body also available. Stainless steel bottom plates are included when special materials and coatings are ordered. Shafts also available in stainless steel.

Specifications: 1/4 HP, 3450 RPM, ½”NPT horizontal discharge. Maximum viscosity: 500 SSU.
