Idler Rotors Pearlitic gray iron, hardened and thread ground, size 137
Gaskets Cellulose and non-asbestos fiber
Shaft Seal & Bearing: Type B: Buna N bellows mechanical seal, Buna N O-rings
and standard external, permanently grease packed, deep groove ball bearing
- recommended for distillate fuels and lubricating oil or hydraulic fluids.
Type H: Positive drive mechanical seal, Viton O-rings and external high temperature,
permanently grease packed, deep groove ball bearing.
Outlet Pressure 1500 PSIG (103 BAR) maximum for distillate & residual
fuels and crude oils. 2200 PSIG (152 BAR) for lube, seal and hydraulic fluids.
Minimum recommended differential pressure is 40 PSI (2.8 BAR) when viscosity
> 100 ssu.
Inlet Pressure Type B & H: 75 PSIG (5 BAR) maximum, distillate fuel, lube-
sizes 106-187
Type H: 40 PSIG (2.7 BAR) maximum, residuals and crude oil- sizes 106-187
Viscosity 33 SSU (2.0 CST) minimum
Type B: 3000 SSU (650 CST) maximum (consider cold start)
Type H: Viscosities above 3000 SSU (650 CST)
Temperature Type B: 0 to180°F (-18° to 82°C) Type H: 0 to 250°F
(-18 to 121°C)
Speed See curve termination for maximum speed. Do not exceed 1800 RPM when
pumping residual fuels or crude oil due to the presence of abrasives and contaminants.
Drive Direct only.
Rotation Clockwise facing pump shaft standard.
Mounting May be foot mounted in any orientation.
Filtration Inlet strainers are required to keep contaminants and abrasives
out of the pump and must be selected in consultation with the strainer vendor
to prevent pump starvation. Normally, 60 mesh (0.01 inch- 238 micron) for
light and 1/8-3/16 inch (3-5mm) openings for heavy oils are recommended. Return
line filters for closed loop systems also recommended.
Motor: Reliance 30 HP, 2940 RPM,
380V/50Hz/3Phase, 41.2 Amps, TEFC Enclosure, Continuous Duty, Safety Factor:
1.15. Frame: 286TS, ID: 1MAF65558.
Specifications
Series 12D Imo pumps are intended for relatively high pressure service on
petroleum or similar viscosity liquids. Typical applications include crude
oil pipeline service, fuel atomization for burning in a steam boiler, fuel
injection for combustion gas turbines, fluid power service on hydraulically
operated machinery, gas sealing in centrifugal compressors and hydrostatic
bearing support. These pumps are hydraulically balanced in both the axial
and radial directions which eliminates bearing loads due to discharge pressure.
The single bearing is external to the liquid pumped and does not rely on the
lubricating qualities of the pumped liquid. The single mechanical seal is
exposed only to inlet pressure. 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.
