The GH Single Screw Pump with Bridge Breaker Agitator is a high-performance industrial pump designed for handling viscous, shear-sensitive, and solid-laden fluids in demanding industrial applications. This specialized pump combines the robust GH single-screw pump design with an integrated bridge breaker agitator, ensuring continuous flow and efficient material transfer even in tanks prone to material bridging or sedimentation.
Constructed with high-quality stainless steel or abrasion-resistant alloys, the GH Single Screw Pump delivers exceptional durability, corrosion resistance, and reliability. The integrated bridge breaker agitator prevents material accumulation and bridging in storage tanks or silos, allowing for uninterrupted feeding of viscous or slurry-like substances.
This pump is ideal for industries such as chemical, food, pharmaceutical, wastewater treatment, and heavy industry, where high-viscosity materials, solids, or abrasive slurries must be transferred, mixed, or dosed precisely. Its modular design allows easy integration into existing pipelines, storage tanks, and process lines, while offering seal-less or mechanical seal options for hygienic or aggressive fluid handling.

The integrated bridge breaker agitator ensures continuous material flow, preventing bridging or compaction of viscous or semi-solid substances. Its rotor and stator configuration minimizes pulsation and shear, preserving product quality during pumping.
The GH Single Screw Pump with Bridge Breaker Agitator is used in industries and applications that require reliable viscous material transfer and tank de-bridging.
High-viscosity adhesives and resins: Ensures continuous flow from tanks to mixers.
Corrosive slurries and chemical pastes: Stainless steel or alloy construction prevents corrosion.
Polymer solutions and coating materials: Maintains uniform consistency during pumping.
Thick sauces, syrups, and pastes: Prevents bridging in storage tanks and ensures smooth transfer.
Honey and molasses: Continuous flow for batching and filling lines.
Chocolate, peanut butter, and other viscous foods: Gentle handling preserves product integrity.
Creams, ointments, and gels: Hygienic models with CIP/SIP compatibility ensure contamination-free transfer.
Biopharmaceutical slurries: Prevents settling and ensures uniform feed to process lines.
Active ingredient suspensions: Maintains homogeneity during pumping.
Sludge pumping: Breaker agitator prevents compaction in storage tanks.
Thick slurry transfer: Handles high solid content fluids effectively.
Dewatering feed: Smooth pumping to dewatering units or treatment lines.
Mineral slurries: Handles abrasive, viscous material with high solids content.
Cement and grout transfer: Prevents bridging and blockages.
Construction material pumping: Consistent flow for continuous operations.
To ensure optimal operation and longevity, follow these guidelines:
Mounting: Install horizontally or vertically according to process requirements.
Connections: Secure inlet and outlet using flanges or sanitary fittings as appropriate.
Drive Alignment: Ensure proper alignment with electric, VFD, pneumatic, or hydraulic drive.
Priming: Pre-fill pump or start at low speed to avoid dry running.
Start-Up: Begin at low speed to gently prime viscous fluids.
Flow Control: Adjust speed using VFD or manual controller for precise delivery.
Agitator Operation: Set bridge breaker agitator speed to prevent material bridging in tanks.
Monitoring: Check vibration, temperature, and noise to ensure smooth operation.
Cleaning: Perform CIP/SIP cycles for hygienic models; flush abrasive materials to prevent wear.
Routine Inspection: Examine seals, bearings, rotor, and agitator for wear.
Lubrication: Maintain proper lubrication for drive components.
