Understanding Your Application Needs

Before you start looking for an External Gear Pump Manufacturer, it is essential to evaluate your specific application requirements. Consider the following:

  • Fluid Type: What kind of fluid will you be pumping? Is it viscous, corrosive, or abrasive? Determine the oil viscosity and fluid characteristics to ensure the pump is suited for the task.
  • Pressure Requirements: Know the maximum and minimum pressure your system requires. Choose a pump that can handle the specific pressure range needed for efficient operation.
  • Temperature Conditions: Identify the operating temperature range. High temperatures may require special materials or lubricants.

Key Specifications of External Gear Pumps

When reviewing different external gear pumps, there are several specifications to focus on:

  • Flow Rate: Establish the required flow rate for optimum performance. Your chosen gear pump should meet the desired flow rate without overloading.

  • Drive Type: Gear pumps can come with various drive types like electric, hydraulic, or mechanical. Ensure the drive type aligns with your operational setup.

  • Size and Weight: Consider spatial constraints. The size and weight of the pump should be compatible with your installation area.

Common Pump Materials

Different materials can influence the durability and performance of external gear pumps. Here are popular materials and their typical applications:
