What is a Heated Gear Pump?
A heated gear pump is a positive displacement pump used to move highly viscous fluids or fluids that solidify at room temperature. It can handle different types of fluids such as asphalt, bitumen, molasses, and chocolate. The pump uses two rotating gears that mesh together to transport the fluid from the suction side to the discharge side. The gears create a vacuum that pulls the fluid into the pump. The pump's housing and gears are heated to prevent the fluid from solidifying or sticking to the pump.
Heated Gear Pump Components
A heated gear pump has several components that work together to transport fluid from one place to another. These components include the following:
- Gears
- Pump Housing
- Bearing
- Shaft
- Drive Gear
- Casing
- Heating Jacket
- Inlet and outlet port
The gears and pump housing are the primary parts of the pump that come into contact with the fluid. They must be made from materials that can withstand the corrosive nature of the fluid. The bearing supports the shaft and ensures that the pump runs smoothly. The drive gear is connected to the motor, which powers the pump. The casing encloses the pump components, while the heating jacket keeps the fluid at the desired temperature. The inlet and outlet ports allow for the fluid to enter and exit the pump.
Applications of Heated Gear Pump
A heated gear pump has several industrial applications in the following areas:
- Chemical and petrochemical industries
- Food and beverage industry
- Pharmaceutical industry
- Cosmetics industry
- Paints and dyes industry
In the food and beverage industry, the pump is used to move chocolates, cream, glucose, syrups, and other viscous fluids. In the pharmaceutical industry, it is used to transport ointments, creams, and other liquid formulations. In the chemical and petrochemical industries, the pump moves molten sulfur, bitumen, asphalt, and others. In the paints and dyes industry, the pump is used to move pastes and paints.
Advantages of Heated Gear Pump
There are several advantages of using a heated gear pump:
- Handles high-viscosity fluids easily
- Controls fluid temperature to prevent solidification
- No pulsation or turbulent flow
- High-pressure capability
- Low noise levels
- Low maintenance required
- Handles hazardous fluids safely
Heated Gear Pump Vs. Other Pump Types
A heated gear pump has some advantages over other pump types:
- Compared to centrifugal pumps, a heated gear pump can handle high-viscosity fluids with ease.
- Compared to diaphragm pumps, a heated gear pump has a higher flow rate and can handle fluids at higher temperatures.
- Compared to lobe pumps, a heated gear pump has a higher pressure capability and is more compact.
However, other types of pumps may be more suitable for specific applications based on fluid properties or operational requirements.
Factors to Consider When Choosing a Heated Gear Pump
When selecting a heated gear pump, the following factors should be considered:
- Viscosity of the fluid
- Temperature range of the fluid
- Flow rate required
- System pressure requirements
- Chemical compatibility of pump materials
- Operating environment conditions
Heated Gear Pump Maintenance
A heated gear pump requires regular maintenance to ensure its continued operation. The pump should be cleaned after use and inspected for wear and tear. The heating jacket should be checked for damage, and the fluid temperature should be monitored to ensure that it is within the required range. The pump housing should be lubricated to prevent corrosion and ensure smooth operation.
Heated Gear Pump Suppliers
Several suppliers provide heated gear pumps for industrial use. Some of the leading suppliers include:
- Viking Pump
- Ampco Pumps Company
