A shoe-type hose peristaltic pump uses 2–4 fixed polyurethane shoes mounted on a rotating carrier to progressively squeeze a heavy-duty reinforced hose (ID 25–250 mm) against a circular housing delivering 0.5–100 m³/h at differential pressures up to 16 bar and viscosities up to 500,000 cP. The larger hose diameter and high-pressure rating make it the industrial-scale choice for abrasive slurry, mining, chemical, and high-viscosity product transfer.
The shoe carrier rotates; each shoe sequentially compresses the heavy-walled reinforced hose between shoe and housing creating a sealed fluid chamber that travels from inlet to outlet. Unlike roller pumps, shoes provide a larger compression footprint reducing hose stress per cycle and extending hose life to 2,000–8,000 hours. The single hose is the only product-wetted component; full-bore passage (no valves or seals in flow path) enables transfer of solids up to 40% by volume and particles up to 50% of hose ID.
Challenges
Hose Replacement Downtime
Hose failure requires stopping process, draining, and 1–2 hour replacement per pump.
Lubricant Contamination of Hose Exterior
Oil-bath lubricated housing requires hose integrity to prevent lubricant ingress into product.
High Pulsation at 2-Shoe Configuration
Two-shoe design produces significant pressure pulsation (2 pulses/rev).
Limited Speed Above 50 m³/h
Hose compression cycle frequency limits maximum speed to prevent thermal hose fatigue.
Abrasive Solids Wear Hose Bore
Hard particle slurries above 5% w/v erode hose bore, shortening hose life progressively.
Solutions
- Quick-Release Hose Clamp System: Patented clamp design reduces hose replacement from 2 hours to 20 minutes.
- Food-Grade Lubricant-Free (Dry-Running) Shoe Design: Eliminates lubrication contamination risk for food, dairy, and pharmaceutical service.
- 4-Shoe Configuration for Smooth Flow: Four shoes reduce pulsation to ±8% of mean pressure acceptable without dampeners.
- VFD Speed Control with Hose Temperature Monitoring: Thermal sensor on hose outer wall triggers speed reduction if fatigue temperature is reached.
- Abrasion-Resistant Hose (Natural Rubber + SBR Core): Specially compounded hose bore extends life 3× against mineral slurry and abrasive product.
Applications
- Mining & Minerals: Abrasive slurry transfer, tailings pumping, ore concentrate and paste fill pumping.
- Chemical: Acid, alkali, and aggressive solvent transfer without seal contamination.
- Food & Beverage: Fruit pulp with seeds, tomato paste, jam with fruit pieces, meat paste industrial transfer.
- Pharmaceutical: API slurry, granulation wet mass transfer, filter cake unloading.
- Wastewater: Sludge transfer, biosolids pumping, filter press feed, thickener underflow.
