3D
Quick Overview
THREE SCREW PUMP
Rated Flow: 4 to 397 gpm (16 to 1501 l/min)Max Inlet Pressure: 50 to 75 PSIG (3.4 to 5.2 bar)
Max Outlet Pressure: 500 PSIG (34.5 bar)
The 3D series pumps is a general purpose design suitable for many applications including lubrication, fuel transport and burner service, low pressure hydraulic applications and hydraulic elevator service. Pump shaft is generously sized to allow belt drive if desired (mechanical seal versions only).
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.
