HHP Jacketed Insulation High Viscosity Pump Introduction

The HHP jacketed insulated high viscosity pump features an internal gear-driven impeller (rotor) that rotates the internal rotor in the same direction within the fully enclosed pump body. The crescent shape of the pump body and the front cover separates the suction and discharge ports. As it rotates, a vacuum is formed at the suction port, drawing in the liquid. The rotor then transports the liquid to the discharge port, where it is pressurized and expelled from the pump, completing the liquid transfer.

HHP jacketed thermal high viscosity pump structure

The annular high viscosity pump is mainly composed of the inner and outer rotors, shaft, pump body, front cover, bracket, seal, and bearings. The sealing is available in two types: mechanical seal and packed seal. For media with high temperature, high viscosity, high density, and strong corrosiveness, a packed seal is recommended.

Advantages of HHP Jacketed Insulation High Viscosity Pumps:

The high viscosity pump (high viscosity rotor pump, asphalt transfer pump) is mainly composed of inner and outer rotors, shaft, pump body, pump cover, bracket, seal, and bearing.

2 Smooth liquid transportation, pulse-free, low vibration, and low noise.

3 The high viscosity pump (high viscosity rotor pump, asphalt transfer pump) has a linear function relationship between speed and flow rate, allowing the flow rate of the pump to be adjusted by changing the speed. High viscosity pumps are suitable for the conveyance of high viscosity media. The shaft end of the high viscosity pump uses a mechanical seal.

The high viscosity pump (high viscosity rotor pump, asphalt transfer pump) maximizes leakage prevention.

5 Suitable for outdoor installation, the fully enclosed magnetic coupling housing protects the external magnet from contacting moisture or external substances.

6 Available materials for various standard sliding bearing types: cast iron, copper, graphite, tungsten carbide.

7 Standard magnet material is neodymium-iron-boron alloy. The optional samarium cobalt magnets allow for a high operating temperature of up to 250 degrees Celsius.

8 Can be transported in both directions.

The external heating jacket for the front cover and magnetic coupling shielding sleeve is a standard optional component.

10-way zipper design.

11 Standard flanged connection, pump head only available.

12 Features an inner and outer casing for protection.

13 Integrated Cooling System Design: A cooling cycle system integrated within the pump, no external cooling required.

14 Dynamic Axial Balance System, reduces axial load to a minimum, lowers power consumption, and extends service life.

15. Hermetically sealed magnetic coupling housing enhances operability. Flow stability: Flow rate is directly proportional to the gear speed, independent of pressure.

High Viscosity Gear Pumps (High Viscosity Rotor Pumps, Asphalt Transfer Pumps) Features:

Smooth Flow: No pulsations or pressure wave peaks; no pipeline vibration.

Versatility: With just an adjustment of the rotor shaft position, the same pump can discharge both diluted solutions and high-viscosity liquids such as asphalt, syrup, resin, polymers, etc.

Reversibility: The liquid flow can be reversed by changing the direction of the gear rotation, allowing the pump to operate efficiently in both directions.

Self-priming: The pump generates high vacuum, enabling rapid self-priming at high self-priming heights, depending on the physical properties of the fluid being pumped (temperature, vapor pressure, viscosity, etc.).

Suggested: Only two moving parts: the drive wheel and the driven wheel, with only one shaft seal.

Robust heavy-duty structure: Low-speed operation. The oversized ball bearing outer housing can withstand axial and radial loads.

Low wear rate: Since the driven wheel and the driven gear are not in a multiple relationship. This means that wear can be evenly distributed across each gear. Because each gear on one gear contacts each gear on the other gear an equal number of times.

Wear Adjustment System: The wear on the rotor edge can be compensated by adjusting the position of the rotor shaft. This way, even under considerable wear, the pump's stability can be maintained.

Simple maintenance, low maintenance rate: Inspection and adjustment can be performed without moving the pump, pipes, or pump drive unit.

Interactivity: Standard component design allows for replacement between different materials and parts with varying characteristics. For example: There are various shaft sealing systems to choose from, and jacketed housings and shaft covers can also be installed to replace standard parts.

Port location can be adjusted: The pump housing can rotate on the bearing housing to suction and discharge liquids from different positions.

Heating jacket preheating: Can be cast integrally with the housing or mounted on the end cap, or installed on the packing gland cover.

Bypass Valve: The bypass valve is installed on the pump and is easy to adjust. Some models of pumps feature a double valve with a heating jacket.

HHP jacketed thermal high viscosity pump working principle:

High-viscosity pumps are rotary positive displacement pumps with internal gears. The liquid flow is generated by two gears, the driving gear and the driven gear. The internal gears are embedded within the external gears, separated by a crescent-shaped baffle. As the gears rotate, the liquid is drawn into the space enclosed by the two gears and the crescent baffle. When the gears mesh, the liquid is compressed and expelled from the pump. Therefore, the liquid flow is smooth, with a large capacity and a compact structure.

Specially designed jacketed pump for asphalt: Asphalt pump with temperature control, capable of quickly melting solidified asphalt inside the pump before startup. Jacket options are available in the bracket, end cover, and bearing areas to prevent asphalt from solidifying inside the pump.
