hopper feed pump for harsh material such as dewatered sludge

Hopper feed pumps are designed with a rectangular hopper feed, screw propeller design, and bridge breaker to ensure efficient and consistent operation. Featuring compact design, low maintenance costs and customized optimization options, they have been used in many industries for material handling.
It has been widely used wherever high viscosity, low fluidity or even non-fluid media need to be handled, especially in wastewater treatment, food processing, chemical and other industrial fields.

hopper feed pump Main Parameters:

• Conveying capacity: 0.1m³/h ~ 200m³/h
• Pressure: up to 4.8MPa or higher

hopper feed pump features and advantages:

1. Conveying low-fluidity or non-fluidity medium: especially suitable for high viscosity and high solid content medium, such as resin, dewatered sludge, concentrated pulp, etc.
2. Rectangular hopper feeding: the rectangular hopper and screw propeller design optimizes the feeding and material conveying efficiency, capable of handling various materials with viscosity or solids.
3. Optimized design: The hopper and feeding screw can be customized and optimized according to specific process requirements.
4. High-pressure conveying capacity: the pump can withstand up to 4.8MPa or higher pressure, adapt to the harsh working environment.

hopper feed pump Structural features:

1. Direct connection frame design: pump and drive device directly flange connection, compact structure, small footprint, light weight, reducing the length of the pump, reducing the overall weight of the equipment and maintenance costs. Users can also choose the bearing frame type.
2. Low maintenance costs: simple structural design makes pump maintenance easier and less costly.
3. With bridge breaking device: specially designed bridge breaking device can prevent the occurrence of bridging phenomenon in the poor fluidity of the material, to avoid the clogging of the pump chamber, to ensure the long-term stable operation of the equipment.

hopper feed pump Application fields:

1. Sewage treatment: used for conveying dewatered sludge, thickened sludge and other high viscosity and high solid content of the waste.
2. Food industry: for conveying all kinds of media with viscosity, such as concentrated fruit juice, slurry, etc.
3. Chemical industry: suitable for conveying resin, viscous chemical solutions and other high-viscosity media.
4. Other industries: such as pulp concentrates, oil sludge, etc. need to transport high viscosity and solid-containing media.

Preventing bridging phenomenon:

Bridging phenomenon often occurs in the poor fluidity of the medium, especially in the suction inlet of the pump, the material may accumulate, clumping, resulting in the inability to enter the pump chamber normally, thus causing the pump to run dry, which may result in damage to the equipment. For this reason, the feed pump is designed with a bridge-breaking device to ensure smooth material flow and prevent the occurrence of bridging phenomenon.

The role of the bridge-breaking device:

Through the specially designed low-power bridge-breaker, regularly stirring the media, destroying the material bridging state, to ensure that the material can continue to flow into the pump chamber, to avoid clogging and equipment damage.
