BW Series Insulation Pump

BW Series Insulation Pump

The BW Series Insulation Pump is a specially designed positive displacement pump equipped with a heating (thermal insulation) jacket, intended for the efficient transfer of high-viscosity, temperature-sensitive, or easily solidified media. By maintaining a constant temperature during pumping, the BW Series ensures smooth fluidity, stable flow, and reliable operation even under low ambient temperature conditions.

This series is widely used in industries such as petroleum, chemical processing, asphalt production, food processing, pharmaceuticals, and coatings, where materials require heating to remain in a pumpable state. The insulation structure can be heated by steam, thermal oil, or hot water depending on process requirements.

Product Features

Integrated Heating Jacket Design
The pump casing is equipped with a thermal insulation jacket that allows continuous heating to prevent medium solidification or crystallization.

Suitable for High-Viscosity Media
Designed to handle viscous, semi-solid, or temperature-sensitive liquids such as asphalt, resin, grease, wax, and heavy oil.

Stable and Continuous Flow
Ensures smooth and pulse-free fluid delivery with stable pressure output, even for difficult-to-flow materials.

Strong Adaptability to Temperature Conditions
Maintains optimal operating conditions by controlling media temperature during transportation.

Reliable Self-Priming Capability
Provides strong suction performance and stable start-up even under high-viscosity conditions.

Durable and Long Service Life
Manufactured with high-strength materials and precision machining for wear resistance and long-term stable operation.

Flexible Heating Media Options
Compatible with steam heating, thermal oil heating, or hot water circulation systems.

Working Principle

The BW Series Insulation Pump operates based on a positive displacement mechanism (gear, screw, or rotor type depending on configuration). During operation, the built-in heating jacket continuously maintains the temperature of the pump chamber and the transported medium. This prevents solidification and reduces viscosity, allowing the pump to transfer materials smoothly from the suction side to the discharge side with stable flow and minimal resistance.

Main Applications

The BW Series Insulation Pump is widely used in:

• Asphalt and bitumen transportation systems

• Petroleum and heavy oil transfer

• Resin and polymer processing

• Wax and paraffin melting and transfer
