Manufacturers supply Mini Oil Pump with variable piston pump

Oil Pump is a critical component designed to circulate, transfer, or pressurize oil within mechanical systems, ensuring proper lubrication, cooling, and operational efficiency. These pumps are engineered to handle various oil types, including engine oil, hydraulic oil, and industrial lubricants across a wide range of temperatures and pressures. Constructed from durable materials such as cast iron, aluminum alloys, stainless steel, and wear-resistant polymers, oil pumps are built to withstand prolonged exposure to viscous fluids, abrasive particles, and harsh operating conditions.

Optimized for specific tasks, common types include gear pumps, rotary vane pumps, and centrifugal pumps. For example, trochoidal gear pumps (gerotor pumps) are widely used in automotive engines for their compact design and reliable low-pressure oil circulation, while screw pumps excel in high-viscosity industrial applications like fuel transfer.

Key Features

1. High Efficiency and Flow Control:

Deliver flow rates from 5 L/min to 500 L/min, and it’s adjustable to system requirements through variable-speed drives or pressure relief valves.

Ideal for steady lubrication, gear pumps provide consistent flow with minimal pulsation.

2. Robust Material Construction:

Stainless steel or hardened alloy components resist corrosion from acidic or sulfur-containing oils.

Polymer seals (e.g., Viton or PTFE) ensure compatibility with synthetic lubricants and high-temperature oils (up to +150°C).

3. Versatile Design Options:

Submersible oil pumps handle submerged applications like sump oil drainage.

Self-priming models eliminate the need for manual priming, enhancing usability in remote or emergency scenarios.

4. Pressure Handling Capability:

Operate under pressures up to 300 bar (piston pumps) for high-demand hydraulic systems.

Built-in pressure relief mechanisms prevent system overloads and component damage.

5. Energy Efficiency:

Optimized impeller or rotor designs reduce power consumption, particularly in continuous-duty applications.

Electrically driven pumps (AC/DC) offer precise control for energy-sensitive environments.

6. Low Maintenance and Longevity:

Sealed bearings and replaceable wear plates minimize downtime.

Easy-access inspection ports simplify routine maintenance and part replacement.

7. Adaptability to Viscous Fluids:

Centrifugal pumps with wide impeller channels handle high-viscosity oils (e.g., gear oils, heavy fuel oil).

Heating jackets (optional) maintain oil fluidity in cold climates.
