Series 6D Specifications

Casing-   High shock capacity ductile (nodular) iron. Consult Imo for steel case availability.

Rotor Housing-   Pearlitic gray iron for rotor sizes 106 through 187; bronze sizes 218 and larger.

Power Rotor- Alloy steel, nitride hardened and thread ground

Idler Rotors-   Pearlitic gray iron, induction hardened and thread ground for sizes 106 through 187; alloy steel, nitride hardened and thread ground

Gaskets-   Cellulose and non-asbestos fiber

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, fluoroelastomer o-rings and external high temperature, permanently grease packed, deep groove ball bearing.

Accessories-   Completely mounted, built to order pump/driver assemblies are available with baseplates, ANSI RF spool pieces, NEMA 'C' face adapters.

Outlet Pressure-   1500 PSIG (103 BAR) maximum for lube, seal and hydraulic oils.  1000 PSIG (70 BAR) maximum for distillate, residual and crude oils.  Minimum recommended differential pressure is 40 PSI (2.8 BAR).

Inlet Pressure-   Type B & H: 75 PSIG (5 BAR) maximum, distillate fuel, lube- sizes 106-187.  50 PSIG (3 BAR) maximum, distillate fuel, lube- sizes 218-400.  Type H: 40 PSIG (2.7 BAR) maximum, residuals and crude oil- all sizes. 

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, sizes 106-187: 0 to 250°F (-18 to 121°C) for <1800 RPM, 0 to 225°F (-18 to 107°C)  for > 1800 RPM. Sizes 218 and up: 0 to 200°F (-18 to 93°C).

Drive-   Direct only.  Magnetic Drive configurations also available.

Rotation-   Clockwise facing pump shaft .

Mounting-   May be foot mounted in any orientation. Flange mounting optional for certain applications.

Filtration-  Inlet strainers are required to keep contaminants and abrasives out of the pump. They 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.
