Product Overview
An Industrial Hose Pump (heavy-duty peristaltic pump) is a self-priming, positive displacement pump engineered for severe-duty fluid transfer. It isolates the pumped medium entirely inside a reinforced elastomeric hose, ensuring that the fluid contacts only the hose interior and internal pipe connections.
Working Principle: Rotating rollers or shoes mounted on a rotor compress a reinforced rubber hose sequentially. This mechanical action creates a continuous vacuum behind the roller (P_suction) and displaces the fluid forward (P_discharge), eliminating backflow without requiring check valves.
Core Advantages:
• Seal-less & Valveless Design: Eliminates mechanical seals, glands, and check valves, completely preventing leaks, clogging, and product contamination.
• Dry-Running Capability: Can run dry indefinitely without damaging internal components.
• High Volumetric Efficiency: Maintains consistent flow rates regardless of viscosity changes; reversible flow direction.
• Gentle Pumping Action: Low internal shear makes it ideal for shear-sensitive fluids and fragile flocculants.
Typical Media Handled: Abrasive slurries, tailings, ceramic slips, corrosive chemicals (H2SO4, NaClO, FeCl3), high-viscosity sludge, and solid-laden wastewater.
Typical Industries: Mining and mineral processing, municipal/industrial wastewater treatment, chemical processing, ceramics/paint production, and tunneling (bentonite slurry).

Operating Limits: Operating temperature range is -20°C to +85°C (dependent on hose compound). Viscosity limit is up to 100,000 mPa·s.
The hose is the single most critical wear component. Our hoses feature a multi-layer construction: an inner tube, multiple plies of high-strength braided nylon cords, and an outer rubber cover finished by precision CNC grinding.
NR (Natural Rubber):
Excellent abrasion resistance and high resilience. Ideal for mining slurries, sand, and aggregate water.
NBR (Nitrile Rubber):
High resistance to oils, greases, and hydrocarbon-based sludge.
EPDM:
Superior resistance to polar chemicals, concentrated acids, caustics, and ozone.
CSM (Hypalon):
Outstanding resistance to strong oxidizing agents, concentrated mineral acids, and harsh chemicals.
Hose Mandrel Curing: Hoses are manufactured using automated mandrel-wrapping technology, ensuring uniform wall thickness and precise inner diameter tolerance (±0.2 mm), which prevents uneven roller stress.
Rotor & Housing Machining: Pump casings and rotors are machined on CNC boring centers to guarantee exact concentricity and alignment, reducing mechanical friction and extending bearing life.
Factory Testing: Every pump undergoes a 2-hour hydro-static pressure test (at 1.5x working pressure) and performance verification for flow rate and suction lift prior to dispatch.
Certifications: ISO 9001 quality management system; CE compliance for European machinery directives.
Application Assessment & Operating Guidelines
Suction Condition:
Install the pump as close to the source as possible. Flooded suction is recommended for high-viscosity or heavy solid-laden fluids. Max dry suction lift reaches up to 8 meters with a primed hose.
Lubrication:
The pump housing requires a low level of specialized lubricant (food-grade glycerin or silicone oil) to cool the hose and reduce friction against the roller/shoe. Maintain fluid level up to the center of the rotor shaft.
Drive Configuration:
Standard assembly includes a heavy-duty helical-bevel gearbox coupled with an inverter-duty AC motor (VFD compatible for precise flow control).
When evaluating suppliers for heavy-duty industrial hose pumps, verify the following operational capabilities:
Hose Manufacturing Capability: Confirm whether the supplier formulates and cures their own elastomer hoses or relies on generic third-party sourcing. Proprietary rubber compounds directly dictate hose fatigue life.
Spare Parts Traceability: Ensure immediate stock availability for replacement hoses, shims, and rotor rollers to minimize unplanned plant downtime.
Engineering Support: Request clear performance curves (Flow vs. Pressure vs. RPM) tailored to your specific fluid density and solid concentration.
