IMO 3D Series
MFG in Monroe, NC & Columbia, KY USA
Series 3D is a general purpose three screw pump available in 19 different displacements. These pumps incorporate full hydraulic balance which cancels axial and radial thrust loads due to discharge pressure.
Mechanical sealed pumps have a single external ball bearing that does not rely on the lubricating qualities of the pumped liquid. The pumps are equipped with replaceable housings (liners) and most sizes are available with an optional steel case. Axial inlets also available in most sizes.
Series 3D pumps are applied for lubrication services, fuel oil transfer and burner applications, hydraulic elevator supply, coolants and many other industrial uses. Very low airborne noise levels are normal for Imo three screw positive displacement pumps as are high operating efficiencies and non-pulsating delivery of flow.
Three-Screw Pumps
The Superior Pumping Technology
Discover our three-screw pumps - the clear choice for superior performance and versatility. The unique design with three interlocking spindles provides an extremely efficient and smooth flow, resulting in impressive overall efficiency.
In addition to excellent controllability, the self-priming pumps offer minimal pulsation and remarkably quiet operation, even at high discharge pressures.
Our three-screw pumps are true all-rounders, capable of handling a wide range of fluids of varying viscosities - from low-viscosity fluids to highly viscous substances. It’s robust design and the high wear resistance of the spindles ensure reliability and long life, making them the ideal choice for critical applications in a variety of industries.
