Product Description

Product Specification :

An Oil Hand Pump is a manual suction and discharge device used to transfer oils, fuels, and non-corrosive liquids from one container to another (typically from a 205L drum to a smaller vessel). It eliminates the need to tip heavy barrels and provides a controlled flow for machinery refueling or oil changes.

1. Common Types

Rotary Vane Pump: Uses a hand crank to rotate vanes inside a chamber. Provides a continuous, high-volume flow. Ideal for low-to-medium viscosity oils.
Lever Action Pump: Uses a vertical pumping motion. Best for high-viscosity lubricants (up to SAE 90 or 140 gear oil).
Siphon Pump: A simple, lightweight plastic pump that uses a bellows or bulb to start a gravity-fed flow.
Vertical Piston Pump: A basic "up-and-down" plunger design, often used for smaller chemical or oil containers.

2. Material & Construction

Feature	Specification
Body Material	Cast Iron (heavy-duty), Aluminum, or Polypropylene (chemical resistant).
Seal Material	Nitrile (Buna-N) for standard oils; Viton for fuels/chemicals.
Suction Tube	Telescopic or sectional steel/plastic to reach the bottom of 55-gallon (205L) drums.
Outlet Spout	Curved Metal (rigid) or Flexible PVC Hose with a nozzle.
