The Heavy Duty High Flow Hose Pump is engineered for continuous, heavy-duty industrial fluid transfer handling highly abrasive, corrosive, shear-sensitive, or high-viscosity media. Built on a positive displacement peristaltic architecture, the pumped fluid is totally isolated within a multi-layer reinforced elastomer hose. Because only the inner tube contacts the media, the design entirely eliminates mechanical seals, gland packings, check valves, and internal mating faces-the primary root causes of premature wear, product contamination, clogging, and hazardous leakage.
Working Principle
Fluid displacement is driven by mechanical shoe or roller compression acting directly against the reinforced hose. As the rotor turns, mechanical compression is released, and the natural restitution of the resilient hose creates a powerful dry vacuum-achieving self-priming up to 8.5 meters. The subsequent rotor pass drives the trapped fluid forward in a completely sealed, continuous volume. This direct-displacement mechanism guarantees zero slip at rated operating pressure and prevents internal fluid churning, protecting fragile structures from degradation.
Core Technical Advantages
• Zero Mechanical Seals & Flushes: Eliminates external flush water systems, seal faces, and leakage vectors inherent in centrifugal and progressive cavity pumps.
• Full Bi-directional Reversibility: Operates in reverse at identical flow rates and pressures to safely clear blocked suction lines or empty piping networks.
• Shear-Sensitive Fluid Protection: Low internal velocities preserve the structural integrity of delicate polymers, flocculants, crystal suspensions, and fragile solid mixtures.
• Indefinite Dry-Running Capability: Operates continuously against closed discharge valves or in a dry suction state without causing thermal degradation, friction wear, or mechanical failure to the hose and rotor assembly.
• Rigorous Hydrostatic Proofing: Every structural pump casing undergoes 100% hydrostatic pressure testing at 1.5 times the maximum rated working pressure prior to factory dispatch.
Typical Media Handled
• Mining & Minerals: Mineral slurries, thickener underflow, tailing slurries, and heavy-density mineral concentrates.
• Chemical Processing: Concentrated acids, caustic solutions, titanium dioxide slurries, and viscous polymer emulsions.
• Wastewater & Environmental: Dewatered sludge, lime slurry (milk of lime), polymer dosing, and primary sewage grit.
• Ceramics & Construction: Abrasive ceramic slips, clay slurries, cement grouts, and concrete additives.
Technical Specifications & Selection Guide
Selecting the correct industrial hose pump requires matching system head, media viscosity, and continuous duty cycle against verified hydraulic performance curves.

Supplier Verification & Manufacturing Capability
Machining Precision: Pump housings and rotor assemblies are machined on CNC horizontal boring centers to maintain dimensional tolerances within +/- 0.05 mm, ensuring precise hose compression geometry.
Hose Testing Protocol: Elastomer hoses undergo destructive burst testing, durometer hardness testing, and tensile strength verification per ASTM standards for every material batch received.
Full Traceability: Each pump is stamped with a unique serial number linked to raw material mill test certificates (MTCs), motor test reports, and final dynamic balancing logs.
Frequently Asked Questions
Q: What is the expected service life of the reinforced hose, and how do I know when to replace it?
A: Hose life depends on discharge pressure, operational speed, and media abrasiveness. Under standard operating conditions (under 8 bar and moderate speed), industrial hoses achieve 1,500 to 3,000 operational hours. Replacement indicators include a gradual drop in flow rate, exterior surface cracking near the compression zone, or notification from leak-detection sensors installed in the casing floor.
Q: Can this pump run dry, and for how long?
A: Yes. Because the fluid path is entirely contained within the flexible hose and no dynamic mechanical seals are present, the pump can run dry indefinitely without thermal shock, friction wear, or mechanical damage.
Q: How is flow rate regulated on high-flow hose pumps?
A: Flow rate is directly proportional to rotational speed. Output is controlled using a Variable Frequency Drive (VFD) paired with a heavy-duty parallel shaft or helical bevel gear reducer, allowing linear, repeatable flow adjustment from 10% to 100% of maximum capacity.
Q: What is the maximum suction lift capability of the pump?
A: When properly primed and lubricated, the pump delivers a dry suction lift of up to 8.5 to 9 meters of water column, depending on fluid viscosity and vapor pressure.
Q: What information is required to issue an accurate technical quotation?
A: To select the correct pump model and hose compound, provide the following parameters:
Media name, concentration, and specific gravity.
Solid content percentage and maximum particle size.
Operating temperature range and pH level.
Required flow rate and total dynamic head (discharge pressure).
Power supply availability (Voltage/Frequency/Ex-proof classification).
Q: What standard factory acceptance tests (FAT) are conducted prior to shipment?
A: Every unit undergoes a 2-hour mechanical run test, vibration analysis, flow verification against calculated head, and a complete leak check of the lubrication chamber before issuing the factory test certificate.
