Fluid Handling

· Suitable for a wide range including clean, clear, non-abrasive  fluid to fluids  with abrasive, high-solid content.

· Not suitable for high viscosity fluids

· Lower tolerance for entrained gases

· Suitable for clean, clear, non-abrasive fluids.  Specially-fitted pumps suitable for abrasive-slurry service.

· Suitable for high viscosity fluids

· Higher tolerance for entrained gases

· Requires clean, clear, non-abrasive fluid due to close tolerances

· Optimum performance with   high viscosity fluids

· Higher tolerance for entrained gases
