What is a Gear Oil Pump?

A horizontal slewing gear pump circulates gear oil. Gear pumps are categorized as Diesel-driven or motor-driven. Gear pumps can transport oils and other lubricated medium liquids, as long as the liquid temperature is below 60°C. However, gear pumps are inappropriate for media solutions containing significant sulfur, corrosives, hard particles, and fibers. Additionally, extremely flammable, low-flashing medium liquids like gasoline, benzene, etc., should not be transported using gear pumps.

Gear Oil Pump

A gear oil pump is made of gears, shafts, pump bodies, pump covers, bearing sleeves, shaft end seals, and other parts. The gears and shafts have high hardness and are wear-resistant because of strict heat treatment when put in the bushing with the shaft. They deliver lubricant for all functional elements in the pump. The surface residual oil pump has hard teeth. The pump has four bearing sleeves. The end-face interval of the sleeves changes automatically based on the working pressure. Because of a minimal output flow pulse and great volumetric efficiency, the pump's pressure remains stable. The gear oil pump is an essential component of the high-pressure system.

How a Gear Oil Pump Functions

Internal and external gear pumps produce flow when two gears enter and exit a mesh, a common feature of both pumps. The external gear pump uses two identical gears moving in opposition to one another, one of which is powered by a motor, which then drives the other gear. A bearing shaft on either side of the gear supports each gear.

The volume on the pump's input side expands as the gears come out of the mesh. As the gear teeth revolve, liquid flows into the cavity and is trapped there. While liquid does not pass between the gears, it moves around the interior between the teeth and the casing. Finally, pressure is applied to the outlet port due to meshing gears.

Working Principle of Gear Pump

Advantages of Gear Pumps

  • High speed
  • High pressure
  • No overhung bearing loads
  • Quiet operation
  • Design accommodates a wide variety of materials

What is a Barrel Pump?

A barrel pump is a lubricating pump that works best in medium or heavy-duty service circumstances. A quick build-up of lubricating system pressure is required in air-operated central stations or bulk lubricant transfer; air-operated barrel pumps are used. Lubricants often move from the original refinery drums to the reservoirs on the central lubrication systems using air-operated barrel transfer pumps. Barrel pumps are made with high-alloy components, corrosion-resistant parts, and high-quality seals, making them highly effective with less noise and air consumption. Barrel pumps are available in 8, 10, and 16 GPM.

How a Barrel Pump Works

A barrel pump is made of an immersion tube, a motor section, and a pump section. The motor is positioned on top of the immersion tube’s exterior. The immersion tube is as long as the container. This tube is deep and sealed to an opening on top of the container and fits through this opening. Depending on the lubrication, several material constructions and tube lengths are offered to accommodate varying container depths. The pump section is situated at the bottom of the immersion tube. The pump's expanded shaft is housed in a sealed column, driven from the top of the immersion tube. The pumped liquid travels to the discharge port between the sleeve and the tube.

Barrel Pump

Applications of barrel pumps

  • Industrial chemistry and research labs
  • Petroleum sector
  • Water treatment
  • Textiles bleach
  • Power facilities
  • Hospitals

Barrel pumps are designed to fit a certain type of container. For instance, the immersion tube might need to be longer to drain another container since it couldn't get to the bottom of it. The ability to exchange parts makes repurposing barrel pumps simple. Barrel pumps designed for a certain fluid may not discharge another due to a difference in viscosity or chemical incompatibility.

Benefits of barrel pumps

The main benefit of a barrel pump is it reduces risks associated with handling containers manually. It simplifies handling spills, leaks, hazardous gases, and accidents. In addition, pumps for barrels are portable and lightweight, making it simple to move them between containers.
