Description
🔧 Working Principle:
Depending on the application, these pumps may be of the:
-
Positive Displacement type (gear, vane, diaphragm) – used for oils and viscous fuels
-
Centrifugal type – for high-volume, lower-viscosity fuel movement
The pump draws liquid through the inlet, and using mechanical energy (usually from an electric or manual motor), pressurizes and pushes the fuel through the outlet.
🔧 Key Components
Component | Description |
---|---|
Pump Housing / Casing | Encloses internal parts and directs fuel/oil flow; made from aluminum, cast iron, or stainless steel. |
Inlet & Outlet Ports | Entry and exit points for fluid; often threaded or flanged. |
Displacement Mechanism | Core component that moves the fluid — varies by pump type (gear, vane, diaphragm, impeller). |
Motor / Drive System | Powers the pump — can be electric (AC/DC), manual, pneumatic, or hydraulic. |
Shaft | Transfers torque from the motor to the displacement mechanism. |
Shaft Seal / Gasket | Prevents leakage of fuel/oil around rotating shaft. |
Relief / Bypass Valve | Protects pump from overpressure; recirculates excess fuel back to suction side or tank. |
Check Valve | Prevents backflow and maintains direction of flow (often in-line or internal). |
Filter / Strainer (Optional) | Prevents debris from entering the pump and damaging internal parts. |
Pressure Gauge (Optional) | Monitors output pressure for safety and efficiency. |
Flow Meter (Optional) | Measures and displays the quantity of fuel/oil transferred. |
Control Panel (if electric) | Enables start/stop and speed control, with overload protection. |
